Chapter 20 Configuring L2 Virtual Private Networks Monitoring and Maintaining L2VPN Table 20-11 Output (Disposition Router) Class Map Match Criteria (continued) Match Criteria Frame Relay DLCI VLAN ID Packet Length DE bit (Frame Relay) Interface ATM Ethernet Frame Relay HDLC and PPP no no no no no no no no no no no no N/A N/A N/A N/A 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. Command show mpls l2transport show pxf cpu atom show mpls l2transport vc show pxf cpu mpls label show pxf cpu subblocks show ssm debug pxf atom ac debug pxf atom mpls Displays 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. PXF-specific forwarding AToM and LS information for an interface or VCCI (column 1 forwarding information). Information about AToM virtual circuits (VCs) that have been enabled to route Layer 2 packets on a router. 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. Status and PXF-related parameters for the interface and has been extended to display column 0 of AToM status. Platform-specific information about active segments. AToM information related to attachment circuit events. AToM information related to MPLS Forwarding Information (MFI)-driven events. 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.
