9. Verify that the global configuration is available by running the show global-running-config
command.
10.While logged on to the principal node in the logical chassis cluster, copy each saved local
configuration file from the remote location to the principal node as follows:
copy location_config_filename running-config
NOTE
You must run this command for each local configuration file you saved (one for each node).
The configuration file is automatically distributed to all nodes in the logical chassis cluster. Each node
will contain the same global configuration after the above steps are performed. Each node will also
contain the local configuration information of all the other nodes.
11.Verify that the local configurations are available by running the show local-running-config
command.
12.Log in to the principal cluster and make any desired global and local configuration changes. These
changes then are distributed automatically to all nodes in the logical chassis cluster.
NOTE
You can enter the RBridge ID configuration mode for any RBridge in the cluster from the cluster
principal node. You can change the principal node by using the logical-chassis principal priority
and logical chassis principal switchover commands. For more information about cluster principal
nodes, refer to
Selecting a principal node for the cluster on page 77.
Selecting a principal node for the cluster
Logical chassis cluster principal node behavior includes:
• All configuration for the logical chassis cluster must be performed on the principal node.
• By default, the node with the lowest WWN number becomes the principal node.
• You can run the show vcs command to determine which node is the principal node. An arrow in the
display from this command points to the WWN of the principal node.
• You can select any node in the logical chassis cluster to become the principal by running the logical
chassis principal priority command, followed by the logical-chassis principal switchover
command, as shown in the following example (in this example, RBridge ID 5 is being assigned with
the highest priority):
switch# configure
switch(config)# rbridge-id 5
switch(config-rbridge-id-5)# logical-chassis principal-priority 1
switch(config-rbridge-id-5)# end
switch# logical-chassis principal-switchover
A lower number means a higher priority. Values range from 1 to 128.
Until you run the logical-chassis principal switchover command, the election of the new principal
node does not take effect.
Converting a logical chassis cluster to a fabric cluster
To transition all nodes in a logical chassis cluster to a fabric cluster, using default configurations,
perform these steps:
1. Make sure all the nodes that you intend to transition from a logical chassis cluster to a fabric cluster
are online. Run either the show vcs or show vcs detail command to check the status of the nodes.
2. Log in to the principal node on the logical chassis cluster.
