The l2 ping command is a proprietary command that allows a user to trigger an LBM message.
For B-VLANs, specify either the destination MAC address or node name.
Note
The virtual node MAC address does not support CFM Layer 2 ping.
This provides a simpler command syntax than the standard LBM commands, which require the user to specify the MD, MA, and MEP ID information. The l2 ping command provides a ping equivalent at Layer 2 for use with nodes on the SPBM B-VLAN in the customer domain. SPBM B-VLANs support the SMLT virtual option for the source mode.
Important
CFM CMAC Layer 2 ping and Layer 2 traceroute traversing over Fabric Extend tunnels are not supported when originating from a VSP 4450 Series.
