Before You Configure IP
Before you configure IP, created lower-layer interfaces over which IP traffic flows.
For example, to configure an ATM interface:
host1(config)#interface atm 1/0host1(config-if)#atm sonet stm-1host1(config-if)#no loopbackhost1(config-if)#atm clock internal chassishost1(config-if)#interface atm 1/0.10host1(config-if)#atm pvc 10 0 20 aal5snapRefer to the appropriate chapters for information about configuring a specific type of interface.
