Enabling iSLB Configuration Distribution

To enable CFS distribution of the iSLB configuration, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# islb distribute
switch(config)# no islb distribute

Locking the Fabric

The first action that modifies the existing configuration creates the pending configuration and locks the
feature in the fabric. Once you lock the fabric, the following conditions apply:
•
•
iSCSI configuration changes are not allowed when an iSLB CFS session is active.
Note

Committing Changes to the Fabric

To apply the pending iSLB configuration changes to the active configuration and to other MDS switches
in the fabric, you must commit the changes. The pending configuration changes are distributed and, on
a successful commit, the configuration changes are applied to the active configuration in the MDS
switches throughout the fabric, the automatic zones are activated, and the fabric lock is released.
To commit iSLB configuration changes to other MDS switches in the fabric, activate iSLB automatic
zones, and release the fabric lock, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# islb commit

Discarding Pending Changes

At any time, you can discard the pending changes to the iSLB configuration and release the fabric lock.
This action has no affect on the active configuration on any switch in the fabric.
