Initially Configuring the POS Interface

You should configure the following properties for a newly installed POS OC-12c uplink interface:

IP routing

IP address

Encapsulation type

Clock source

You should also configure the following properties to match those of the interface at the other end:

Keepalive messages

Cisco Discovery Protocol (CDP)

Cyclic redundancy check (CRC)

Scrambling

Encapsulation type
