Provisioning And Booting Up The Vc In Standalone Mode - Nokia 7210 Configuration Manual

Virtual Chassis
5.2 Provisioning and Booting Up the VC in
The 7210 SAS supports manual bootup for a VC.
To provision a node to belong to a VC, it must be configured with the chassis-role
parameter set to standalone-vc. The chassis-role parameter is a BOF parameter
in the boot loader context.
Of the two nodes configured as CPM-IMM, one becomes the active CPM and the
other becomes the standby CPM, ready to move to the active role should the current
active CPM fail.The node designated as the active CPM uses the configuration file
available locally or remotely at boot up. It distributes the configuration to all members
of the VC. Setting the chassis-role parameter to standalone-vc ensures that the
member nodes of the VC do not use any local configuration at boot up.
The IMM-only node configuration and the service configuration is always done on the
active CPM. The active CPM-IMM node distributes the configuration information to
other VC members when the user has saved the TiMOS configuration.The IMM-only
nodes receive the service configuration from the active CPM through VC
management messages, while the standby CPM receives the service configuration
through the high availability (HA) reconcile mechanism.
The active CPM-IMM also sends out VC management packets with VC configuration
information to IMM-only member nodes. The IMM-only nodes use the management
packets to obtain the VC configuration and join the VC.
The VC requires a single IP address and MAC address to be managed as a single
entity. The current active CPM owns the IP address and responds to all the
messages sent to this IP address and uses the MAC address as required (for
example, for ARP).
The show>chassis command displays power, fan, and alarm statuses of the VC by
consolidating the statuses of all cards provisioned in the VC. The show>card
command displays power, fan, and alarm statuses for individual cards.
