logical-chassis principal-priority

Sets the priority of a switch to assign a specific RBridge ID the role of principal node in a logical
chassis cluster.

Synopsis

logical-chassis principal-priority priority-value

no logical-chassis principal-priority

Operands

priority-value

Sets the priority for the switch. A lower number means a higher priority.
Values range from 1 through 128.

Defaults

None

Command Modes

RBridge ID configuration mode

Description

If all switches boot up at the same time, the default priority is the same and all switches will
compare their mutual intents. The switch with the lowest switch WWN becomes the principal
switch. However, you can use this command to select the principal switch in a logical chassis
cluster. For this command to take effect, you need to issue the logical-chassis principal-switchover
command.

Usage Guidelines

This command can be used only on nodes that are part of a logical chassis cluster. The node,
however, can be disconnected from the cluster when you issue the command.

Use the no form of this command to remove a priority value from this node.

You can view the principal priority in both the show running config (using the rbridge-id operand)
and show vcs detail command outputs (both are run in Privileged EXEC mode).

Examples

To set the principal priority to 5 for switch that is in logical chassis cluster:

switch# configure

switch(config)# rbridge-id 5

switch(config-rbridge-id-5)# logical-chassis principal-priority 5
