Cajun A500 ATM Switch User Guide

U Third-party ATM switches and Lucent ATM switches -  In these configurations, you 

need to both set the link type and configure either a static route , PVC, or PNNI. The 

section "Configuring/Modifying the Link Type", later in this chapter, describes how 

to configure the link type and activate the Cajun A500 port. The section 

"Configuring Permanent Virtual Channels and Paths"  describes how to configure a 

PVC.

Configuring the Link Types for the Cajun A500

Specify a link type to be assigned to an Cajun A500 port determines the service to be 

supplied by the Cajun A500 over that port. This is done by specifying a link type from 

the available set of link types for each active port in your Cajun A500. 

Note:  When you first bring up an Cajun A500, all ports are disabled (down). Ports 

must be in this state when you configure the link type for the port.

Note:  If using ILMI 4.0, and the external device supports auto-configuration, the 

system auto configures and all that is necessary is bring up the port.

To configure the link type for a Cajun A500 port:

1. Bring the ATM port down, if it is not already.
2. Configure the link type.

3. Bring the ATM port up.

4. View the link types specified for each port.

5. Configure custom link types.

The following sections explain how to complete each of these steps.

Guidelines for Determining the Link Type

The following guidelines help determine which link type to use. The value you select 

depends upon what the system directly attached to your Cajun A500 uses to establish 

communication with the Cajun A500.

U Systems such as LAN (non-ATM) switches or servers typically support UNI 3.0, 3.1, 

or 4.0 signaling, using the Interim Local Management Interface (ILMI) protocol. 

U Third-party ATM switches and Lucent ATM switches that support UNI 3.0 or 3.1 

signaling, use PNNI.
