High Performance Local Ethernet Bridge. Self-Learning Bridge with Support for 2,000 Nodes. 115VAC.



The LANLine 5220L high performance Local bridge provides the simplicity needed for typical networking needs, yet offers sophisticated capabilities which can be enabled for even the most demanding application. As a self-learning bridge, the unit can be installed in virtually any network topology in a matter of minutes, without requiring ANY prior configuration. But as the need dictates, advanced features such as SNMP management and custom protocol filtering can be enabled. As a local bridge,

LANLine 5220L helps simple and complex networks achieve maximum performance via wire rate filtering and forwarding, as well as source and destination address filtering. Protocol filtering enables the network manager to designate which protocols the LANLine 5220L will forward and which it will screen out. Access to resources can be restricted based on protocol type if desired. Port map filtering enhances network security by ensuring that specific nodes cannot communicate with devices on the second LANLine 5220L LAN port.

The filter table manages up to 2,000 nodes and with its programmable aging timeout feature, which removes inactive nodes from the table, LANLine 5220L can support any size network. LANLine 5220L supports the IEEE 802.1 D Spanning Tree Algorithm. Spanning Tree enables multiple pathways between LANs to be supported, yet only one path is active at any time. Should the primary link fail, a secondary path can be activated to guarantee access to key resources.

An easy-to-use console enables speedy configuration and provides a wide range of statistics to facilitate management of the network. The console can be accessed from any device on the network via TELNET, or through direct connection of a terminal to the console port. SNMP support ensures LANLine 5220L can be managed by any SNMP management system.
