Configuring Optional Serial Layer 2 PVC Parameters
This task describes the commands you can use to modify the default configuration on a serial Layer 2
PVC.
Prerequisites
Before you can modify the default PVC configuration, you must create the PVC on a Layer 2
subinterface, as described in the “Creating a Serial Layer 2 Subinterface with a PVC” section on
page 529.
Restrictions
The configuration on both ends of the PVC must match for the connection to be active.
SUMMARY STEPS
1. configure
2. interface serial interface-path-id.subinterface l2transport

4. encap [cisco | ietf]
5. service-policy {input | output} policy-map
6. fragment end-to-end fragment-size
7. fragment-counter
8. end
