Chapter 4      Configuring PPP over ATM with NAT
  Configure the ATM WAN Interface
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
Example:
Router(config)# interface atm 0
Router(config-if)# 
Enters interface configuration mode for the ATM 
interface (labeled ADSLoPOTS or G.SHDSL on 
the back of your router).
Note
This interface was initially configured 
during basic router configuration. See 
Step 2
pvc vpi/vci
Example:
Router(config-if)# pvc 8/35
Router(config-if-atm-vc)# 
Creates an ATM PVC for each end node (up to ten) 
with which the router communicates. Enters ATM 
virtual circuit configuration mode.
When a PVC is defined, AAL5SNAP 
encapsulation is defined by default. Use the 
encapsulation command to change this, as shown 
in 
. 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
Step 3
encapsulation {aal5auto | aal5autoppp 
virtual-template number [group group-name] | 
aal5ciscoppp virtual-template number | 
aal5mux protocol | aal5nlpid | aal5snap
Example:
Router(config-if-atm-vc)# encapsulation 
aal5mux ppp dialer
Router(config-if-atm-vc)# 
Specifies the encapsulation type for the PVC and 
points back to the dialer interface. 
For details about this command and additional 
parameters that can be set, see the
Step 4
dialer pool-member number
Example:
Router(config-if-atm-vc)# dialer 
pool-member 1
Router(config-if-atm-vc)# 
Specifies the ATM interface as a member of a 
dialer profile dialing pool. The pool number must 
be in the range of 1–255.
