The following steps describe how to manually bring up a VC using nodes shipped from the factory that are being booted up for the first time.
Users can boot up a single node or a set of nodes that are to be part of a VC. As well, users can power on one node, all the nodes, or a set of nodes; there is no restriction on the power sequence. The following steps describe the sequence when all nodes are booted up together; however, the steps here do not dictate the order of service provisioning and do not preclude preprovisioning of services on the active CPM. Service preprovisioning is allowed after the VC configuration, including the VC node member configuration, is complete.
The CPM-IMM nodes are configured through the BOF and do not require further configuration to be part of the VC.
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.
