ATM AAL	AAL5
ILMI keepalives	Not supported

Initially Configuring the ATM Uplink Interface

You should configure the following properties for a newly installed ATM uplink interface:

•IP routing

•IP address

To initially configure the ATM uplink interface, perform the following steps, beginning in global configuration mode:

	Command	Purpose
Step 1
	Router(config)# ip routing	Enables IP routing.
Step 2
	Router(config)# interface atm	Enters interface configuration mode and specifies the ATM
	slot/subslot/interface	interface to configure.
	Router(config-if)#
Step 3
	Router(config-if)# ip address	Assigns an IP address and subnet mask to the interface.
	ip-address subnet-mask
Step 4
	Router(config-if)# atm clock	Specifies the internal clock for the interface. The default mode
	internal	for the clock is no internal, which is the same as the line clock.
Step 5
	Router(config-if)# no shutdown	Enables the interface with the previous configurations.
