Enabling this setting forces TCP/IP to transmit Ethernet packets using 802.3 SNAP encoding. By default, the stack transmits packets in DIX Ethernet format. It will always receive both formats.

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value called 'ArpUseEtherSNAP' using the settings below.

Exit your registry, you may need to restart or log out of Windows for the change to take effect.


(Default)	REG_SZ	(value not set)
ArpUseEtherSNAP	REG_DWORD	0x00000001 (1)

Settings:

System Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters]
Name: ArpUseEtherSNAP
Type: REG_DWORD (DWORD Value)
Value: (0 = false, 1 = true)
