Configure the ATM WAN Interface

Perform these steps to configure the ATM interface, beginning in global configuration mode.

	Command	Purpose
Step 1
	interface type number	Enters interface configuration mode for the ATM
		interface (labeled ADSLoPOTS or G.SHDSL on
	Example:	the back of your router).
	Router(config)# interface atm 0	Note This interface was initially configured
	Router(config-if)#	during basic router configuration. See
		“Configure WAN Interfaces” section on
		page 1-7.
Step 2
	pvc vpi/vci	Creates an ATM PVC for each end node (up to ten)
		with which the router communicates. Enters ATM
	Example:	virtual circuit configuration mode.
	Router(config-if)# pvc 8/35	When a PVC is defined, AAL5SNAP
	Router(config-if-atm-vc)#	encapsulation is defined by default. Use the
		encapsulation command to change this, as shown
		in Step 3. The VPI and VCI arguments cannot be
		simultaneously specified as zero; if one is 0, the
		other cannot be 0.
		For details about this command and additional
		parameters that can be set, see the Cisco IOS
		Wide-Area Networking Command Reference.
Step 3
	encapsulation {aal5auto aal5autoppp	Specifies the encapsulation type for the PVC and
	virtual-template number [group group-name]	points back to the dialer interface.
	aal5ciscoppp virtual-template number	For details about this command and additional
	aal5mux protocol aal5nlpid aal5snap}
		parameters that can be set, see the Cisco IOS
	Example:	Wide-Area Networking Command Reference.
	Router(config-if-atm-vc)# encapsulation
	aal5mux ppp dialer
	Router(config-if-atm-vc)#
Step 4
	dialer pool-member number	Specifies the ATM interface as a member of a
		dialer profile dialing pool. The pool number must
	Example:	be in the range of 1–255.
	Router(config-if-atm-vc)# dialer
	pool-member 1
	Router(config-if-atm-vc)#
