CONFIGURATION GUIDE RELEASE 22.9.R1
Virtual chassis
Step 4. On the active CPM node, add the configuration for the new IMM-only node using the
config>system>vc-stack>vc-stack-node command, specifying the MAC address of the new
IMM-only node and reusing the same slot number as the failed IMM-only node.
Step 5. Connect to the console of the replacement IMM node.
Step 6. Connect the new IMM node to the stacking ring.
Step 7. Reboot the IMM node by toggling the power to it
Step 8. On boot up, interrupt the boot process and specify imm-only for the vc-stack-node-type boot
loader.
Step 9. Save the BOF configuration and let the boot proceed.
Expected outcome
The node will boot up as an IMM-only node. The appropriate stack LED on the front panel of the
node will glow steady.
Expected outcome
Services are not interrupted, as the active CPM (CPM-A) is present and has not been rebooted (assuming
the active CPM has an uplink to the network). If one of the IMM-only nodes is converted to a CPM-IMM
node, the services on that IMM node are affected as the node is rebooted to effect the change to a CPM-
IMM node.
5.7.3 Replacing the current active CPM node with another node
If the active CPM node needs to be replaced and has not failed, switchover to the standby CPM can be
forced before using the procedure outlined in Replacing a standby/active CPM-IMM node with another
CPM-IMM node.
5.7.4 Expanding a VC by adding a new IMM-only node
This scenario is similar to Replacing an IMM-only node with another node except that instead of replacing
an existing IMM-only node, a new node is being added. This requires the configuration file on the
active CPM to be updated by adding the new IMM-only node VC configuration parameters using the
config>system>vc-stack>vc-stack-node command, without deleting or modifying any existing VC
configuration parameters.
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.
