4.4 VLAN Loopback
The VLAN Loopback feature provides the capability for Layer 2 per VLAN loopback. It includes a loopback
responder and a loopback initiator (Layer 2 Ping). The frame format and message processing is 802.1ag
compatible. Any vendor having implemented the 802.1ag standard can loop back the 9145E initiated
loopback message and vise versa.
Using the loopback initiator, the 9145E can perform a Layer 2 Ping test. For the loopback responder, the
9145E implements a set of default values so it can loop back any VLAN ID and any MD level, and the
Ethertype will be defaulted to the standard 0x8902.
The user may change the Ethertype via UI, Telnet or SNMP. Both IEEE 802.3 and LLC SNAP formats are
supported. The 9145E loopback responder responds to both formats. For the loopback initiator, the user
selects which format to use.
