Interface Type Section This section prompts you for the ATM interface type configuration of the ports on the Interface Modules which are installed in the CoreBuilder 7000 family ATM switch chassis.
There are four interface types: UNI, E-IISP, IISP and PNNI. The UNI type is normally used when an edge device is connecting to a switch. The E-IISP type is normally used when connecting to another CoreBuilder 7000 or 9000 switch. The IISP type is used to connect to a device which does not recognize the E-IISP protocol used by the CoreBuilder 7000 family ATM switch such as switches of other vendors. The PNNI type is normally used to connect switches to other similar or different types of switches when you want each switch to have a global view of the entire network.
PNNI is available in version 4.5 extended only.
To enter the interface type configuration:
1At the NNI type of port prompt, enter the NNI type for the port you just specified. Enter “U” for UNI, enter “E” for E-IISP, enter “I” for IISP, or “P” for PNNI.
2Repeat step 1 until you have specified the interface type for all of the ports that are in the Corebuilder 7000 family ATM switch chassis.
