~SELERING │ # Sectra Token Ring Server for DOS Select Ring menu Sectra Token Ring Server for DOS is a DOS program that allows you to monitor and control IEEE 802.5 token ring networks. Sectra resides on a workstation in a ring and can access one or two rings that have a network interface card in the workstation. Sectra allows you to monitor, troubleshoot, and control node access to a token ring network from a single vantage point. Sectra is designed to continuously run on your workstation. If you have to unload it, just press <esc>. For more help, call Thomas-Conrad Technical Services at the following number. Free telephone support is available 24 hours-a-day, 7 days-a-week at (800) 332-8683. Sectra has an easy to use interface. Everything is accessed and controlled from menus. Pressing <F1> in any window gives you context-sensitive help. THE SELECT RING MENU: QUICK REFERENCE The Select Ring menu provides access to Sectra's menu and window system. Before selecting a Sectra function, you must first select a ring. Thereafter, the Sectra functions that you select or data that you display pertain to this ring. The Select Ring menu displays the name of the two rings attached to the workstation, as well as the status of each ring. If you have not assigned a name to each ring, Sectra will display the adapter addresses of each token ring adapter in your workstation. FIELD DESCRIPTIONS: Ring Name: The ring name (if you have supplied a name) or the address of the token ring adapter in the Sectra server. FIELD DESCRIPTIONS: Ring State: The present ring status. A ring can be in one of six states: Uninitialized: Sectra has not yet started collecting data for the ring. Normal: The ring is operating normally--that is, only transmitting AMP and SMP frames. Ring State: Re-organizing: Due to changes on the ring, Sectra is temporarily reorganizing its database for the ring. Beaconing: The ring is transmitting beacon frames, indicating a hard error (an error that prevents normal ring operation). Card not Available: The adapter or driver is not installed or cannot be accessed by Sectra. Adapter Error: The adapter has had an error condition and is attempting to correct it. This is a temporary condition. If the adapter is not able to correct the problem, this error will change to Card not Available. The adapter is not collecting data while in this state. KEYS: <> <> To select a Ring, use the arrow keys to position the cursor on the appropriate ring. <Enter> Displays the View/Manage Ring menu for the selected ring. <F1> Press for help in any Sectra window. For more information, please refer to the User's Guide. ~VIEWMANG │ # View/Manage Ring You can access most of Sectra's menus and windows from the View/Manage Ring screen. In addition, the screen contains a summary of error and configuration information for the selected ring. All counters are subject to a 999,999 limit. If you ever have a counter reach the limit, you should reset the ring counters in the Ring Data window. THE VIEW/MANAGE RING MENU: QUICK REFERENCE FIELD DESCRIPTIONS: Ring Status Window: Adapter Address: The address of the selected ring's adapter in the Sectra server. Ring Status Window: Let Sectra Remove Nodes: Indicates whether you will let Sectra deny access to nodes that shouldn't be on the ring. Nodes can be denied access to a ring for being unauthorized, for being on the ring outside of their allowed time periods, or if they have been manually blocked. Event Logging: Indicates whether Sectra records events for the selected ring. Inserted Nodes: The number of nodes currently inserted in the ring. Total Nodes: The total number of nodes in Sectra's database for the ring, regardless of whether they are currently inserted into the ring. Ring Status Window: Unauthorized Nodes: The number of unauthorized nodes currently inserted into the ring. Beacon Frames: The number of beacon frames that have been transmitted on the ring since the ring counters were last reset. A beacon frame indicates that a hard error has occurred on the ring. A hard error totally disrupts the transmission of user data on the ring. Isolating Errors: The number of isolating errors that occurred on the ring since the ring counters were reset. An isolating error is a soft error that can be isolated to a specific area of the ring. Soft errors can disrupt token ring operation, thus degrading performance. A low number of soft errors can be expected to occur on any ring. Ring Status Window: Non-Isolating Errors: The number of non-isolating errors that occurred on the ring since the ring counters were reset. A non-isolating error is a soft error that cannot be isolated to a specific area of the ring. Counters Reset: The date and time when the error counters for the ring were last reset. View/Manage Ring Menu: View Error Summary: Displays error summary information on a node by node basis. Useful for identifying faulty nodes. View Nodes: Displays the database and extremely detailed error information for each node. View/Manage Ring Menu: View Event Log: Provides a real-time view of ring events currently being logged for the selected ring. Maintains a history of those events. Useful for ring troubleshooting. View Ring Data: Provides an all-in-one display of the selected ring's configuration and error information. Select Events to Highlight: Allows you to choose which events in the event log are highlighted. Select Events to Log: Prevents selected events from being logged. Lets you focus on the events that are important to you. Define Alarms: Determines which conditions on the ring trigger an alarm to get your attention. View/Manage Ring Menu: Specify Ring Parameters: Allows you to change configuration information such as the ring's name. KEYS: <Esc> Exits to the Select Ring menu. <F4> If event logging is turned off, pressing <F4> turns event logging on. When event logging is turned on, pressing <F4> turns event logging off. NOTE: Sectra will not log events for the ring if event logging is off. KEYS: <F8> If you are currently letting Sectra remove nodes, pressing <F8> stops Sectra from removing nodes. Sectra will no longer remove nodes from the ring under any circumstance. If you are NOT letting Sectra remove nodes, pressing <F8> will allow Sectra to remove nodes. Sectra will remove nodes from the ring that are unauthorized, that are on the ring outside of their allowed time periods, or that have been manually blocked. For more information, please refer to the User's Guide. ~MONEVENT │ # Monitor Event Log The Event Log window allows you to monitor events in real-time for the selected ring. To monitor another ring's events, you must go back to the Select Ring menu by exiting help and pressing <esc> twice. For information about specific events, please refer to the User's Guide. If event logging is stopped (indicated by the "Event Logging Stopped" message in the title bar), you will only be able to view past events. To turn event logging on, exit help, press <esc> to return to the Manage/View Ring menu and press <F4> to start event logging. THE EVENT LOG WINDOW: QUICK REFERENCE The Event Log window has two display modes: -> Monitor mode (default) -> History mode In the Monitor mode, the window displays events as they occur. New events are displayed at the bottom of the window. The window automatically scrolls up as needed to display events and the cursor is always at the bottom of the scroll bar. Any attempt to manually scroll the Event Log window when it's in the Monitor mode puts the window into the History mode. In the History mode, the window displays the event log for the ring. You can manually scroll to any event in the log. New events continue to be collected and can be viewed by entering the Monitor mode. Placing the cursor on the last event in the log THE EVENT LOG WINDOW: QUICK REFERENCE returns the window to the Monitor mode. After 15 minutes of inactivity in the History mode, the Event Log window will return to the Monitor mode automatically. If you stay in the History mode for an extended period, Sectra may temporarily exceed the event log file size limit. The event log file will return to normal size upon exiting the History mode. FIELD DESCRIPTIONS: Events: Descriptions of events occurring on the ring. Time: The time at which the event occurred. KEYS: <Esc> Exits the Event Log window and displays the View/Manage Ring menu. <> <> Moves up or down one line in the event log, respectively. Moving to the latest event in the log returns the Event Log window to the Monitor mode. <PgUp> Puts the Event Log window in the History mode and pages up through the event log. <PgDn> Pages down through the event log. Paging down to the latest event in the log returns the Event Log window to Monitor mode. KEYS: <Home> Puts the Event Log window in the History mode and displays the oldest events in the event log. <End> Puts the Event Log window in the Monitor mode and displays the latest events in the event log. For more information, please refer to the User's Guide. ~VIEWEVEN │ # Event Log History The Event Log window allows you to view past events for the ring you have selected. To view event history for a different ring, you must go back to the Select Ring menu by exiting help and pressing <esc> twice. For information about specific events, please refer to the User's Guide. THE EVENT LOG WINDOW: QUICK REFERENCE The Event Log window has two display modes: -> Monitor mode (default) -> History mode THE EVENT LOG WINDOW: QUICK REFERENCE In the Monitor mode, the window displays events as they occur. New events are displayed at the bottom of the window. The window automatically scrolls up as needed to display events and the cursor is always at the bottom of the scroll bar. Any attempt to manually scroll the Event Log window when it's in the Monitor mode puts the window into the History mode. In the History mode, the window displays the event log for the ring. You can manually scroll to any event in the log. New events continue to be collected and can be viewed by entering the Monitor mode. Placing the cursor on the last event in the log returns the window to the Monitor mode. After 15 minutes of inactivity in the History mode, the Event Log window will return to the Monitor mode automatically. If you stay in the History mode for an extended period, Sectra may exceed the event log size. THE EVENT LOG WINDOW: QUICK REFERENCE The event log file will return to normal size upon exiting the History mode. FIELD DESCRIPTIONS: Events: Descriptions of events occurring on the ring. Time: The time at which the event occurred. KEYS: <Esc> Exits the Event Log window and displays the View/Manage Ring menu. <> <> Moves up or down one line in the event log, respectively.

For more information, please refer to the User's Guide. ~RINGDATA │ # Ring Data Window The Ring Data window displays configuration information and error summary information about the ring. All counters are subject to a 999,999 limit. THE RING DATA WINDOW: QUICK REFERENCE FIELD DESCRIPTIONS: Adapter Address: The address of the token ring adapter in the Sectra server. FIELD DESCRIPTIONS: Errors: Beacon Frames: The number of beacon events that occurred on the ring since the ring's error counters were reset. Isolating Errors: The number of isolating errors that occurred on the ring since the ring's error counters were reset. Non-Isolating Errors: The number of non-isolating errors that occurred on the ring since the ring's error counters were reset. Counters Reset: When the ring error counters were last reset. Nodes: Allow Unauthorized Nodes: Indicates whether unauthorized nodes are allowed in the ring. Let Sectra Remove Nodes: Whether or not Sectra can remove a node from the ring for being either unauthorized, not allowed or blocked. Inserted Nodes: The number of nodes currently in the ring. Authorized Nodes: The number of authorized nodes currently inserted into the ring. Event Log: Event Logging: Indicates whether or not Sectra is actively recording events for the ring. KEYS: <F10> Resets the error counters that Sectra maintains for the ring. Does not reset the error counters for each node. <Esc> Exits the window and returns to the View/Manage Ring menu. For more information, please refer to the User's Guide. ~ERRORSUM │ # Error Summary The Error Summary window displays the total number of beacon frames, isolating errors, and non-isolating errors for each node inserted into the ring. Nodes are listed on the left of the window, beginning with the adapter in the server. Error counts for each node are shown on the right of the window. All counters are subject to a 999,999 limit. THE ERROR SUMMARY WINDOW: QUICK REFERENCE FIELD DESCRIPTIONS: Node: The nodes currently inserted into the ring are displayed in ring order. A starburst () means that if you let Sectra remove nodes, this node will be removed. An exclamation point (!) means that this node is unauthorized. FIELD DESCRIPTIONS: Beacon Frames: The total number of beacon frames transmitted by the node since the node's error counters were reset. A beacon frame indicates that a hard error has occurred on the ring. Isolating: The total number of isolating errors reported by the node since the node's error counters were reset. An isolating error is a soft error that degrades ring performance, and can be isolated to a specific area of the ring. A low rate of soft errors normally occur as nodes enter or leave the ring. Non-isolating: The total number of non-isolating errors reported by the node since the node's error counters were last reset. A non-isolating error is a soft error that cannot be isolated to a specific area of the ring with the exception of the Receiver Congestion error, which occurs at the node reporting the error. KEYS: <F7> Resets the error counters that Sectra maintains for all nodes currently inserted on the ring. <F10> Resets the error counters that Sectra maintains for the highlighted node. <Esc> Exits the window and returns to the View/Manage Ring menu. For further information, please refer to the User's Guide. ~ANODDATA │ # Node Data for Inserted Nodes The Node Data window displays configuration information about the ring's nodes. There are two versions of the window: one for inserted nodes (nodes currently inserted into the ring) and one for inactive nodes (nodes not in the ring). Press <F6> to display the Node Data Window for Inactive Nodes. The Node Data Window for Inserted Nodes displays the inserted nodes on the left side of the window. The nodes are displayed in the order in which they occur on the ring, beginning with the token ring adapter in the network server. Going higher in the list represents going upstream on the ring. Going lower represents going downstream. Data for the currently highlighted node is displayed in the right side of the window. THE INSERTED NODE WINDOW: QUICK REFERENCE FIELD DESCRIPTIONS: Node List: The nodes currently inserted. A starburst () by a node means that if you let Sectra remove nodes, this node will be removed. An exclamation point (!) means this node is unauthorized. Name: A user-supplied name for the selected node. If no name has been supplied, this field is blank. Type: Specifies the type of function performed by the node (for example, file server, workstation, print server). This is user-supplied text. Address: The selected node's adapter address. FIELD DESCRIPTIONS: Inserted: The date and time the selected node was last inserted into the ring. Last Seen: The date and time Sectra last saw the selected node communicate on the ring. Authorized: Indicates whether a node is authorized to be on the ring. You authorize a node by selecting that node and pressing <F9> or by pressing <F5> to authorize all nodes. If unauthorized nodes are not allowed on the ring, and you let Sectra remove nodes (<F8> in View/Manage Ring menu), Sectra will remove all unauthorized nodes from the ring. First Seen: The date and time Sectra first saw the selected node in the ring. FIELD DESCRIPTIONS: NAUN: The name of the selected node's nearest active upstream neighbor (NAUN). Allowed: The days of the week and hours of the day during which the selected node is allowed on the ring. If a node is inserted during a time other than when it is allowed, it will be removed from the network, provided you first let Sectra remove nodes. Removed: The number of times (since the node was placed in Sectra's database) that Sectra has forced the selected node off the ring. Location: The physical location of the selected node (user-supplied text). FIELD DESCRIPTIONS: Machine: The type of computer at the selected node (user-supplied text). Adapter: The type of token ring adapter at the selected node (user-supplied text). Driver: A description of the token ring driver at the selected node (user-supplied text). Comment: A comment about the selected node (user-supplied text). KEYS: <F2> Displays the Error Counters window for the node selected on the left side of the window. <F3> Displays the Modify Node Data window for the node selected on the left side of the window. <F5> Authorizes all inserted nodes on the ring. <F6> Displays the Node Data for Inactive Nodes. <F8> When a node is blocked from inserting into the ring, selecting the node and pressing this key unblocks the node. When a node is not blocked from inserting into the ring, selecting the node and pressing this key blocks the node. Blocking a node removes the node from the ring and blocks KEYS: <F8>... the node from further access to the ring. Remember, the node will not actually be blocked unless you first let Sectra remove nodes. <F9> Authorizes the selected node to be inserted into the ring. A node that is not authorized to be inserted into the ring is marked with an exclamation point (!). <Ins> Displays the Add Node window, which is used to add a node to the Sectra database. <Esc> Exits the window and returns to the View/Manage Ring menu. For more information, please refer to the User's Guide. ~NODERROR │ # Node Error Counters The Node Error Counters window displays the error counters that Sectra maintains for each node. All counters are subject to a 999,999 limit. The three node error categories are: Beacon frames: A beacon frame indicates that a hard error occurred. Hard errors totally disrupt normal ring operation by not allowing any user data to be transferred on the ring. Isolating Errors: An isolating error is a soft error that can be isolated to a specific area of the ring. Soft errors can disrupt token ring operation, thus degrading performance. A low number of soft errors can be expected to occur on any ring. Non-isolating errors: A non-isolating error is a soft error that cannot be isolated to a specific area of the ring. Appendix A of the User's Guide provides a detailed description of all hard and soft errors recognized by Sectra. THE NODE ERROR COUNTERS: QUICK REFERENCE FIELD DESCRIPTIONS: Beacon Frames: The number of beacon frames transmitted by the node indicating a hard error exists on the ring upstream from the node. Isolating Errors: Abort Delimiter: The number of times the node cancels a frame it is transmitting. Isolating Errors: A/C (Access Control): The ARI/FCI bits are not being set properly in AMP and SMP frames. The node downstream is unable to determine the address of its upstream neighbor. Burst: The number of times a node detects that no data was transmitted by its nearest active upstream neighbor for 5 half-bit times. Internal: The number of times the node discovers an error internal to itself. Line: The number of times the node detects a frame corrupted with bit errors. Other Isolating: The number of other isolating errors detected by the node. Non-isolating Errors: Frame Copy: The number of times the node receives frames intended for itself that have already been read by another node. Frequency: The number of times the node detects that the active monitor ring clock differs too much from its own. Lost Frame: The number of times the node does not receive back the frame it has transmitted. Receiver Congestion: The number of times the node loses a frame addressed to it because of a lack of buffer space. Token: The number of times the Active Monitor detects an error has occured in the token. Non-isolating Errors: Other non-isolating: The number of other non-isolating errors detected by the node. For All Counters: Errors/Minute: The average number of errors per minute for the node since its counters were last reset. Counters Reset: The date and time when the node's error counters were last reset. Session: Indicates how many errors have occurred since the node was last inserted into the ring. For All Counters: Total: Indicates how many errors have occurred since Sectra started counting errors for the node. KEYS: <F2> Displays the node data window for the node selected. <F10> Resets all error counters for the node to zero. Both the session and total counts are reset. <Esc> Exits to the View/Manage Ring menu. For more information, please refer to the User's Guide. ~INODDATA │ # Node Data for Inactive Nodes The Node Data Window for Inactive Nodes displays configuration data for nodes not currently inserted into the ring. Press <F6> to return to the Node Data Window for Inserted Nodes. THE INACTIVE NODE WINDOW: QUICK REFERENCE FIELD DESCRIPTIONS: Node list: Displays the inactive nodes. A starburst () by a node means that if you let Sectra remove nodes, the node will be removed when it attempts to insert. An exclamation point (!) means that the node is unauthorized. FIELD DESCRIPTIONS: Name: A user-supplied name for the selected node. If no name has been supplied, this field is blank. Type: Specifies the type of function performed by the selected node (for example, file server, workstation, print server). This is user-supplied text. Address: The selected node's adapter address. State: The possible node states are as follows: Blocked - The node is not on the ring and is blocked from accessing the ring. State: Not Allowed - The node is not currently allowed on the ring but is allowed on the ring at other times. Not Inserted - The node is currently allowed on the ring but is not inserted into the ring. FIELD DESCRIPTIONS: Last Seen: The date and time Sectra last saw the selected node in the ring. Authorized: Indicates whether a node is authorized to be on the ring. You authorize a node by selecting that node and pressing <F9> or by pressing <F5> to authorize all nodes. FIELD DESCRIPTIONS: First Seen: The date and time Sectra first saw the selected node in the ring. Allowed: The days of the week and hours of the day during which the selected node is allowed on the ring. If a node is inserted during a time other than when it is allowed, it will be removed from the network, provided you first let Sectra remove nodes (<F8> in the View/Manage Ring menu). Removed: The number of times (since the node was placed in Sectra's database) that Sectra has forced the selected node off the ring. Location: The physical location of the selected node (user-supplied text). FIELD DESCRIPTIONS: Machine: The type of computer at the selected node (user-supplied text). Adapter: The type of token ring adapter at the selected node (user-supplied text). Driver: A description of the token ring driver at the selected node (user-supplied text). Comment: A comment about the selected node (user-supplied text) KEYS: <F3> Displays the Modify Node Data window for the node selected on the left side of the window. KEYS: <F5> Authorizes all inactive nodes to insert into the ring. <F6> Displays the Node Data for Inserted Nodes window. <F8> Removes a node from the ring and blocks the node from further access to the ring. Remember, Sectra will not actually block a node unless you first let Sectra remove nodes (<F8> in the View/Manage Ring menu). Unblocking a node returns the node to normal control, which means that the node may insert into the ring unless it is not allowed on at this time or it is unauthorized and unauthorized nodes are not allowed. KEYS: <F9> Authorizes the selected node to insert into the ring. A node that is unauthorized is marked with an exclamation point (!). <Ins> Displays the Add Node window, which is used to add a node to the Sectra database. <Del> Deletes the node selected on the left of the window from the Sectra database. <Esc> Exits the window and returns to the View/Manage Ring menu. For more information, please refer to the User's Guide. ~ADDNODE_ │ # Add a Node The Add Node window is used to add a node to Sectra's database. If you let Sectra remove nodes, and unauthorized nodes are not allowed on the ring, then this is your only method for allowing new nodes on the ring. Press <Esc> to return to the previously displayed Node Data window. The only information that you must enter in the Add Node window is the node's adapter address. All other information is optional. THE ADD NODE WINDOW: QUICK REFERENCE FIELD DESCRIPTIONS: Adapter Address: Specifies the node's adapter address. This is the only information that you must supply to add the node into the database. Name: Specifies a name for the node (user-supplied text). Sectra uses this name to identify the node in its menus and windows. Type: Specifies the type of function performed by the node (for example, file server, workstation, print server). This is user-supplied text. FIELD DESCRIPTIONS: Allowed Days: A menu that allows you to specify the days of the week during which the node is allowed on the ring. To select days, place the cursor on the Allowed Days field, press <Enter>. Press <ins> to add allowed days. Press <del> to restrict daily access. Press <esc> to exit the menu. Allowed Time: Specifies the hours during the day when the node is allowed on the ring. This a continuous period of time with start and stop points that must be specified to the hour and minute. A 24-hour numbering scheme (0-23 hours) is used. Location: Specifies the physical location of the node (user-supplied text). FIELD DESCRIPTIONS: Machine: Specifies the type of computer at the node (user-supplied text). Adapter: Specifies the type of token ring adapter at the node (user-supplied text). Driver: Specifies the type of token ring driver at the node (user-supplied text). Comment: A comment about the node (user-supplied text). KEYS: <Esc> Exits to the previously displayed Node Data window. If any changes were made, you will be asked if you really want to add this node to the database. ~DELNODE_ │ # Delete a Node Deletes the node selected on the left side of the window from the Sectra database. Deleting a node does not necessarily prevent it from inserting in the ring later on. In fact, Sectra will create a new database entry if the node you delete inserts in the future. The node, however, will be treated as a new and unauthorized node. Only delete nodes that are unlikely to join the ring again later on. Enter <N> to CANCEL the deletion. Enter <Y> to DELETE the node from the database. ~MODNODE_ │ # Modify Node Data The Modify Node Data window is used to add or change information about nodes that are already in the database. Press <Esc> to return to the Node Data window. THE MODIFY NODE WINDOW: QUICK REFERENCE FIELD DESCRIPTIONS: Adapter Address: Specifies the node's adapter address. This is a read-only field. Name: Specifies a name for the node (user-supplied text). Sectra uses this name to identify the node in its menus and windows. FIELD DESCRIPTIONS: Type: Specifies the type of function performed by the node (for example, file server, workstation, print server). This is user-supplied text. Allowed Days: A menu that allows you to specify the days of the week during which the node is allowed on the ring. To select days, place the cursor on the Allowed Days field and press <Enter>. Press <ins> to add allowed days. Press <del> to restrict daily access. Press <esc> to exit the menu. Allowed Time: Specifies the hours during the day when the node is allowed on the ring. This a continuous period of time with start and stop points that must be specified to the hour and minute. A 24-hour numbering scheme (0-23 hours) is used. FIELD DESCRIPTIONS: Location: Specifies the physical location of the node (user-supplied text). Machine: Specifies the type of computer at the node (user-supplied text).

Comment: A comment about the node (user-supplied text). KEYS: <Esc> Exits to the previously displayed Node Data window. If any changes were made, Sectra asks you to confirm whether or not you really want to save the changes you made. Enter <Y> to SAVE the changes in the database. For more information, please refer to the User's Guide. ~NODEBLOK │ # Node Blocking Node blocking removes a node from the ring until you explicitly tell Sectra to unblock the node. Node blocking can be useful for removing a malfunctioning node from the ring or for temporarily denying a node access to the ring. NOTE: Node Blocking will not remove a node from the ring unless you first let Sectra remove nodes. For more information, please refer to the User's Guide. ~DEFIHIGH │ # Select Events to Highlight You can specify which events Sectra highlights in the event log. This enables you to keep track of ring events that you consider significant. Error events are highlighted by default. To highlight an event, place the cursor over the event with the arrow keys, press <Y> and press <enter>. To no longer highlight an event, place the cursor over the event, press <N> and press <enter>. Appendix A of the User's Guide provides a detailed description of each event. ~DEFIFILT │ # Select Events to Log You can specify which events Sectra displays and logs. This enables you to keep track of ring events. The fewer events you decide to log, the more time the event log history will span. All events are recorded by default. To record an event, place the cursor over the event with the arrow keys, press <Y> and press <enter>. To filter an event, place the cursor over the event, press <N> and press <enter>. Appendix A of the User's Guide provides a detailed description of each event. ~DEFIALAR │ # Alarm Definition The Alarm Definition menu is used to select whether certain error conditions automatically trigger an alarm for the ring. THE ALARM DEFINITION WINDOW: QUICK REFERENCE FIELD DESCRIPTIONS: Errors: Beacon Frames: Specifies whether too many beacon frames per minute on the ring triggers an alarm. If yes, the user must specify the threshold to trigger the alarm. Errors: Isolating Error: Specifies whether too many isolating errors per minute on the ring triggers an alarm. If yes, the user must specify the threshold to trigger the alarm. Non-Isolating Error: Specifies whether too many non-isolating errors per minute on the ring triggers an alarm. If yes, the user must specify the threshold to trigger the alarm. Other Events: Too Many Nodes on Ring: Specifies whether too many nodes inserted into the ring triggers an alarm. If yes, the user must specify the threshold to trigger the alarm. Other Events: Node Removed From Ring: Specifies whether Sectra will send an alarm when it removes a node from the ring. Node Inserted for First Time: Specifies whether a node inserting into the ring for the first time triggers an alarm. KEYS: <Esc> Exits to the View/Manage Ring menu. For more information, please refer to the User's Guide. ~RINGPARS │ # Specify Ring Parameters The Specify Ring Parameters menu is used to configure Sectra for each ring in the network. THE SPECIFY RING PARAMETERS WINDOW: QUICK REFERENCE FIELD DESCRIPTIONS: Adapter Address: The address of the token ring adapter in the network server. This is a read-only field. Ring Name: Specifies the name by which Sectra identifies the ring in its menus. The ring name can contain any printable ASCII character and can be up to 12 characters long. Allow Unauthorized Nodes on Ring: Specifies whether unauthorized nodes are allowed on the selected ring. WARNING: MAKE SURE YOU AUTHORIZE ALL LEGITIMATE NODES BEFORE NOT ALLOWING UNAUTHORIZED NODES ON THE RING. FAILURE TO DO SO MAY RESULT IN NODES BEING REMOVED FROM THE RING THAT SHOULD HAVE ACCESS. Let Sectra Remove Nodes: Specifies whether Sectra will deny access to nodes that shouldn't be on the ring. Nodes can be denied access to a ring for being unauthorized, for being on the ring outside of their allowed time periods, or if they have been manually blocked. WARNING: BEFORE LETTING SECTRA REMOVE ANY NODES FROM THE RING, MAKE SURE YOU HAVE AUTHORIZED LEGITIMATE NODES, UNBLOCK NODES THAT SHOULD NOT BE BLOCKED AND THAT ALLOWED TIME PERIODS ARE APPROPRIATE FOR EACH NODE. FAILURE DO TO SO CAUSES SECTRA TO REMOVE NODES FROM THE RING THAT SHOULD HAVE ACCESS. KEYS: <Esc> Exits the menu and returns to View/Manage Ring menu. ~TOGGLOGN │ # Event Logging Event logging allows you to observe what is happening on the ring in real-time, and maintains a history of recent events. Sectra updates all the error counters and ring configuration information even when event logging is off. If you leave event logging on, you will always have recent ring history at your disposal for troubleshooting. If you leave it off, you will save a small amount of CPU processing time. However, when a problem occurs that requires analysis of ring events, you must first turn event logging on. For more information, please refer to the User's Guide. ~TOGGBLOC │ # Letting Sectra Remove Nodes The node removal process is a very powerful tool for maintaining security and for automating troubleshooting efforts. Nodes can be removed from a ring by explicitly blocking them, by making them unauthorized, or by restricting the time a node is allowed on. If you don't want to use these features, you may disable the entire node removal process. If you stop Sectra from removing nodes, Sectra will NEVER remove nodes from the selected ring. When you are ready to let Sectra remove nodes, it becomes very important you understand the different ways nodes may be removed from the ring. Without this knowledge, you may inadvertently remove users off the network that are legitimately trying to complete their work. When you let Sectra remove nodes, nodes may be removed from the network in the following ways: Blocking: You may want to temporarily block a node from the ring. For instance, you may want to block a malfunctioning node or a station temporarily not in use. <F8> in the Node Data Window for Inserted and Inactive nodes allows you to Block and Unblock nodes. Allowed Times: You may want to allow a node access to the ring for certain specified periods of time. For instance, a receptionist may have access to the ring from 9 AM to 5 PM, but the node should be denied access at other times because the node is in an unsecured area. The allowed times for a node can be changed in the Node Data Window for Inserted and Inactive nodes by pressing <F3>. Unauthorized: You may want to prevent a node that you have never seen before from inserting in your ring. For instance, suppose a hacker inserts into the ring with his own node adapter in the middle of the night. If unauthorized nodes are NOT ALLOWED, then Sectra will remove the hacker node from the ring. WARNING: BE SURE TO AUTHORIZE ALL LEGITIMATE NODES BEFORE INSTRUCTING SECTRA TO REMOVE ALL UNAUTHORIZED NODES. For more information, please refer to the User's Guide. ~CHEKUNAT │ # Allow Unauthorized Nodes on Ring Specifies whether unauthorized nodes are allowed on the selected ring. If unauthorized nodes are not allowed on the ring, then nodes never seen on the ring before will be removed right after they insert. It is recommended that you allow unauthorized nodes on the ring until you know exactly who should and should not be authorized. Remember, Sectra will not remove unauthorized nodes unless you first let Sectra remove nodes. WARNING: MAKE SURE YOU AUTHORIZE ALL LEGITIMATE NODES BEFORE NOT ALLOWING UNAUTHORIZED NODES ON THE RING. FAILURE TO DO SO MAY RESULT IN NODES BEING REMOVED FROM THE RING THAT SHOULD HAVE ACCESS. For more information, please refer to User's Guide. ~RESETALL │ # Reset All Node Error Counters When all node error counters are reset, each node's error counters are set to zero. By resetting the error counters, it is easier to distinguish the nodes reporting errors now, from the nodes that reported errors in the past. ~NOINACTV │ # No Inactive Nodes Right now, every node Sectra knows about is currently inserted in the selected ring. When a node leaves the ring, Sectra will allow you access to the View Inactive Nodes window. ~CONFIG__ │ # Reconfiguring Sectra's Database Sectra maintains a separate database for each ring. Sectra distinguishes between the rings by using the adapter address of each card in the server. In the unlikely event a token ring card fails, or for some reason you decide to replace a old token ring card with a new one, you need to tell Sectra which database goes with which card. Sectra displays one adapter address at a time, and asks you which ring database that adapter is associated with. If you desire, you can erase an existing database by selecting New Ring. For more information, please refer to the User's Guide. ~NOFSBLOK │ # Unable To Block File Server Sectra will not allow you to block the file server from accessing the ring. When you remove the file server from the ring, you not only deny others access to the file server, you also impair Sectra's ability to monitor the ring. ~DUPLADDR │ # Node Address Already Exists The node you are attempting to add already exists. Locate the node in either the Inserted or Inactive Node window and press <F3> to modify the node's data. You can only have one database entry for each unique adapter address on the selected ring. ~MUSTALLW │ # Must Allow Server Access at All Times Sectra does not allow you to limit the period of time the file server can access the ring. When you remove the file server from the ring, you not only deny others access to the file server, you also impair Sectra's ability to monitor the ring. ~MUSTAUTH │ # Server Must be Authorized Sectra does not allow you to make the file server unauthorized. Unauthorized nodes can be removed from the ring. When you remove the file server from the ring, you not only deny others access to the file server, you also impair Sectra's ability to log events. ~UNLOADHL │ # Unloading the Sectra Token Ring Server The Sectra Token Ring Server is designed to run continuously on your workstation. On a well-behaved network, it requires a small amount of CPU time. When there are network problems, it goes to work collecting information to help you return the ring to normal operation. ~NONULLAD │ # You Must Enter a Valid Address You cannot enter an all zero address. Please enter the hexadecimal address of the adapter you wish to add to the ring. If you do not know the adapter address, just insert the adapter into the ring. Sectra will see the node and will automatically enter the node into the ring's database for you. For more information, please refer to the user's guide.
