When the VC configuration information has been committed in the CLI, the active
CPM node sends the VC configuration to all other nodes in the VC through VC
management messages over the stacking ports.
When the IMM-only nodes receive the VC management messages from the active
CPM, they confirm the VC configuration by matching their chassis address to the
MAC address contained in the VC message.They then retrieve the TiMOS image
from the active CPM and use it to boot up.
While booting up with the TiMOS image, the standby CPM node undergoes another
CPM election arbitration process, which results in the node detecting itself as
standby. The node then executes the HA reconcile process and synchronizes its
management and control plane state with the active CPM. It receives the current
running configuration with the VC configuration and the current BOF configuration
present on the active CPM.
The VC is now ready for use.
5.6.2 Subsequent Reboot of the Stack (with Correct BOF
Present)
This scenario assumes that the BOF configured on each node during the first time
boot up is saved locally and contains the VC configuration required for the node to
boot up. It also assumes that the chassis-role parameter in the bootflash is set to
standalone-vc for each node.
The following sequence occurs in the boot loader context and in the TiMOS context.
There is no user intervention required.
• In the boot loader context, all the nodes in the VC read their bootflash and the
BOFs that are present locally, and receive their VC configuration.
• In the boot loader context, the nodes configured as cpm-imm go through a CPM
election process and the node with the lower slot number is chosen as the active
CPM. Both nodes proceed to boot up using the TiMOS image (both.tim).
• In the TiMOS context, both the cpm-imm nodes again read the BOFs that are
present locally and receive their VC configuration.
