Optional Configurations

There are several standard, but optional, configurations that might be necessary to complete the configuration
of your serial SPA.
Configuring the Encapsulation Method
When traffic crosses a WAN link, the connection needs a Layer 2 protocol to encapsulate traffic. To set the
encapsulation method, use the following commands:
SUMMARY STEPS
1. Router# configure terminal
2. Router(config)# interface serial slot/subslot/port:channel-group
3. Router(config-if)# encapsulation encapsulation-type {hdlc | ppp | frame-relay}
4. Router(config-if)# crc {16 | 32}
DETAILED STEPS
Command or Action
Step 1
