cnfspvcprfx

Configure SPVC Prefix—configure a node-level prefix for SPVCs.

For the node to support SPVCs, it must have a 13-byte SPVC prefix that applies to the entire node. No

SPVCs can exist on the node until it has an SPVC prefix. Likewise, to change this prefix, no SPVCs can

exist on the node.

Prerequisites

Setting up a node and a network requires advance planning for the PNNI node addressing scheme. For

basic guidance on the topic of address planning, refer to related material in the Cisco MGX 8850 Switch

Software Configuration Guide, Release 2.

Cisco provides a default SPVC prefix that is the same as the Cisco-supplied ATM address prefix. Each

of these default prefixes contains an International Code Designator (ICD) that is unique to Cisco

Systems. Therefore, Cisco Systems recommends that you change the ICD identifier for both the ATM

address prefix and the SPVC prefix if the node is planned for operation in a public ATM network. If the

node operates in a private ATM network, it can keep the default ATM and SPVC address prefixes.

The following list shows the order of prerequisite commands and the cnfspvcprfx command. All

commands run on the PXM45.
