5.7.5 Removing a Node from a VC (Standby CPM or IMM)

If the node to be removed is the standby CPM-IMM node, see Replacing a Standby/

Active CPM-IMM Node with Another CPM-IMM Node and update the BOF on the

active CPM node by removing the VC configuration parameters for the node being

removed.

If the node to be removed is an IMM-only node, see Replacing an IMM-only Node

with Another Node and update the configuration file on the active CPM node by

removing the VC configuration parameters for the node being removed.

5.7.6 Adding a New Standby CPM Node Into an Existing

This scenario is similar to Replacing a Standby/Active CPM-IMM Node with Another

CPM-IMM Node, with the VC configuration information of the new CPM-IMM node

being added to the BOF of the active CPM node.

5.7.7 Configuration Guidelines for Upgrading, Adding, or

Removing a VC Node

The following configuration guidelines apply for upgrading, adding, or removing a VC

node.

• When upgrading an IMM-only node to a CPM-IMM node, ensure connectivity is

available between the IMM and the current active CPM-IMM node over the

stacking links.

• A power cycle may be required if the role is changed from a CPM-IMM node to

an IMM-only node.

5.8 VC Split Scenarios

A VC split can occur as a result of the following failures in a VC:

• a single stacking link failure

• a single node failure
