Example
In the following example, ATM 3/0/0 is configured as an NNI:
!
interface atm 3/0/0
no atm auto-configuration
atm nni
!
Verifying NNI Configuration
To verify NNI configuration for an ATM interface, use the show atm interface EXEC command:
Switch# show atm interface atm 3/0/0
Interface: ATM3/0/0 Port-type: oc3suni
IF Status: UP Admin Status: up
Auto-config: disabled AutoCfgState: not applicable
IF-Side: Network IF-type: NNI
Uni-type: not applicable Uni-version: not applicable

Interim Interswitch Signaling Protocol Interfaces
The Interim Interswitch Signalling Protocol (IISP) defines a static routing protocol (using manually
configured prefix tables) for communication between ATM switches. IISP provides support for switched
virtual circuits (SVCs) on ATM switches that do not support the Private Network-to-Network Interface
(PNNI) protocol. For more information, see the “Configuring ATM Routing and PNNI” chapter in the
ATM Switch Router Software Configuration Guide.
Figure4-3 shows an example IISP interface that connects the Cisco 6400 to a switch in the ATM cloud.
