Verifying Autoconfiguration
To check if autoconfiguration is enabled or disabled on an NLC interface, use the show atm interface
EXEC command.
In the following example, autoconfiguration is disabled on the OC-3 ATM interface 1/0/0:
Switch# show atm interface atm 1/0/0
Interface: ATM1/0/0 Port-type: oc3suni
IF Status: UP Admin Status: up
Auto-config: disabled AutoCfgState: not applicable

ATM Interface Types
This section describes how to configure NLC interfaces of the following types:
• User-Network Interfaces, page 4-3
• Network-to-Network Interfaces, page 4-5
• Interim Interswitch Signaling Protocol Interfaces, page 4-6
Note Whenever a change in the interface protocol (such as UNI, NNI, or IISP), side, or version is configured,
ATM signaling and ILMI are restarted on the interface. When ATM signaling is restarted, all switched
virtual connections (SVCs) across the interface are cleared; permanent virtual connections are not
affected.
User-Network Interfaces
The User-Network Interface (UNI) specification defines communications between ATM-based products
(a router or an ATM switch) located in a private network and the ATM switches located within the public
carrier networks.
Figure4-1 shows example UNIs configured between the Cisco 6400 and a digital subscriber line access
multiplexer (DSLAM).
