If the stacking ports are not connected together to form a ring connecting all the
nodes of the VC, any failure in the VC (whether a link or a node failure) will isolate
some nodes off of the VC, affecting all the services on those nodes. In addition, if the
uplink is through one of the nodes that has been isolated or has failed, services using
the uplink for the entire VC are affected. The procedure here assumes a ring of
stacking ports is configured.
In the following scenario, it is assumed that a CPM-IMM node has failed and needs
to be replaced. It is assumed that a redundant CPM node is configured and another
CPM-IMM node is currently active. The replacement node might be a new node from
the factory or a node that has been previously used as an IMM node.
Step 1. Use the MAC address or slot number to determine whether the failed node
is CPM-A or CPM-B. The node to be added as a CPM-IMM node must be
configured based on which one failed. For the purposes of this example, it
is assumed that CPM-B (the standby CPM) has failed.
Step 2. Disconnect the stacking port on the failed node and complete the stacking
ring.
Step 3. On the active CPM, remove the configuration of the failed CPM-IMM node
(CPM-B) from the BOF using the bof no vc-stack-node command.
Step 4. On the active CPM, add the configuration of the new CPM-IMM node as
CPM-B to the BOF using the bof vc-stack-node command.
Step 5. Save the BOF for the configuration to take effect immediately.
Step 6. If the replacement node is an existing IMM-only node, follow these steps.
i. Remove the IMM-only node configuration from the configuration file of
the active CPM using the config system vc-stack no vc-stack-node
command.
ii. Connect to the console of the IMM-only node.
iii. Reboot the node by toggling the power button.
iv. On boot up, interrupt the boot process and configure the node as CPM-
IMM (CPM-B) by configuring the following BOF parameters:
• specify cpm-imm for vc-stack-node-type
• specify the slot number and MAC address of each CPM-IMM node
in the bof>vc-stack-node command
Step 7. If the replacement node is a new node, follow these steps.
i. Physically connect the new node into the VC ring (the stacking ports
are connected to form a ring so that an alternate path always exists).
ii. Reboot the node.
iii. Connect to the console of the new node.
iv. Power on the node.
