Usage Guidelines The pvc command and the encapsulation command work together. The use of these commands with
Layer 2 local switching is slightly different from the use of these commands with other applications. The
following list highlights the differences:
• For Layer 2 local switching, you must add the l2transport keyword to the pvc command. The
l2transport keyword enables the PVC to transport Layer 2 packets.
• The Layer 2 local switching encapsulation command works only with the pvc command. You
cannot create switched virtual circuits or VC bundles to transport Layer 2 packets. You can use only
PVCs to transport Layer 2 packets.
