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.
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.
