Chapter 3 Provisioning PXM1E Communication Links

Quickstart Provisioning Procedures

IISP Link Configuration Quickstart

The quickstart procedure in this section provides a summary of the tasks required to configure Interim

Inter-Switch Protocol (IISP) links on Cisco MGX switches. This procedure is provided as an overview

and as a quick reference for those who have previously configured these types of connections.

Note AINI is a newer protocol that is designed to replace the function of IISP. Unless you are configuring a

link with another switch that does not support AINI, you should configure an AINI link instead of an

IISP link. IISP links provide fewer capabilities than AINI links. For example, IISP links cannot support

UNI 4.0 connections.

Step 6

cnfpnportsig <options> At one end of the AINI trunk, VPI and VCI allocation must be

disabled. VPI and VCI allocation is enabled by default on a

PXM1E trunks. To disable this feature, enter the command:

8850_LA.7.PXM.a > cnfpnportsig 1:1.1:1 -vpivcialloc

disable

Step 7

uppnport <portid> When signaling configuration is complete, bring up the port.

Step 8

addaddr <options> Add destination addresses to local end of the trunk.

See the “Defining Destination Addresses for Static Links”

section later in this chapter.

Step 9

addaddr <options> Add static addresses to destination ports. This step is required

when addresses are not dynamically assigned to the CPE at the

destination ports.

See the “Assigning Static ATM Addresses to Destination Ports”

section later in this chapter.ater in this chapter.
