Using default configuration in logical chassis cluster to avoid segmentation issues

Using a command called default-config enable allows a node to rejoin a logical chassis cluster by obtaining the configuration of the principal node in the cluster.

Enabling this feature can eliminate the following segmentation issues:

  • A node rebooting while a global configuration change could not be applied.
  • ISL connectivity to the primary node going down while configuration is in progress.

Brocade recommends not enabling this feature on every node (especially on core nodes) in the cluster.

The following restrictions apply:

  • This command cannot be used on the principal node of the logical chassis cluster.
  • Principal priority cannot be set on a node which has this feature enabled.

For information on how to use this command, refer to the default-config enable command in the Network OS Command Reference.
