Monitoring and Maintaining L2VPN
To monitor and maintain the configuration of L2VPN features, use the following commands in privileged
EXEC mode. Note that with the exception of the show mpls l2transport command, these commands
can produce output that is meant to be used by Cisco Systems technical support personnel only.
Caution Because debugging output is assigned high priority in the CPU process, it can render the system
unusable. For this reason, use debug commands only to troubleshoot specific problems or during
troubleshooting sessions with Cisco Systems technical support personnel. Moreover, it is best to use
debug commands during periods of low network traffic and few users. This decreases the likelihood that
increased debug command processing overhead will affect system use.

Command Displays
show mpls l2transport Information about AToM VCs that have been enabled to route
Layer 2 packets on a router, including platform-independent
AToM status and the AToM capabilities of a particular interface.
show pxf cpu atom PXF-specific forwarding AToM and LS information for an
interface or VCCI (column 1 forwarding information).
show mpls l2transport vc Information about AToM virtual circuits (VCs) that have been
enabled to route Layer 2 packets on a router.
show pxf cpu mpls label PXF-specific forwarding information for a label. The output has
been extended to indicate AToM disposition labels, specifically,
the transport type associated with the label and the set of output
features associated with the label, such as control word and
sequencing.
show pxf cpu subblocks Status and PXF-related parameters for the interface and has been
extended to display column 0 of AToM status.
show ssm Platform-specific information about active segments.
debug pxf atom ac AToM information related to attachment circuit events.
debug pxf atom mpls AToM information related to MPLS Forwarding Information
(MFI)-driven events.
