Verifying CEM for CESoPSN on T1 Interface
Use the following commands to verify the pseudowire configuration for CESoPSN:
• show cem circuit—Displays information about the circuit state, administrative state, the CEM ID of the
circuit, and the interface on which it is configured. If cross connect is configured under the circuit, the
command output also includes information about the attachment circuit status.
• show mpls l2 vc—Displays information about the MPLS VC.
• show mpls l2 vc detail—Displays detailed information about the MPLS VC.
