About CFS Distribution of Allowed Domain ID Lists
You can enable the distribution of the allowed domain ID list configuration information to all Cisco SAN
switches in the fabric using the Cisco Fabric Services (CFS) infrastructure. This feature allows you to
synchronize the configuration across the fabric from the console of a single switch. Because the same
configuration is distributed to the entire VSAN, you can avoid possible misconfiguration and the
possibility that two switches in the same VSAN have configured incompatible allowed domains.
Use CFS to distribute the allowed domain ID list to ensure consistency in the allowed domain ID lists
on all switches in the VSAN.
Note We recommend configuring the allowed domain ID list and committing it on the principal switch.
For more information about CFS, see Chapter 7, “Using Cisco Fabric Services.”
Enabling Distribution
CFS distribution of allowed domain ID lists is disabled by default. You must enable distribution on all
switches to which you want to distribute the allowed domain ID lists.
To enable (or disable) allowed domain ID list configuration distribution using Fabric Manager, perform
this task:
Step 1 Expand Fabricxx > VSANxx > Domain Manager, and then choose Allowed in the Logical Domains
pane for the fabric and VSAN that you want to set the allowed domain ID list for.
You see the CFS configuration in the Information pane.
Step 2 Set the Admin drop-down list to enable and the Global drop-down list to enable to enable CFS
distribution for the allowed domain ID list.
Step 3 Click the Apply Changes icon to enable CFS distribution for the allowed domain ID list.
Locking the Fabric
The first action that modifies the existing configuration creates the pending configuration and locks the
feature in the fabric. After you lock the fabric, the following conditions apply:
• No other user can make any configuration changes to this feature.
• A pending configuration is created by copying the active configuration. Subsequent modifications
are made to the pending configuration and remain there until you commit the changes to the active
configuration (and other switches in the fabric) or discard them.
Committing Changes
To apply the pending domain configuration changes to other SAN switches in the VSAN, 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 SAN switches throughout the VSAN
and the fabric lock is released.
