Chapter 33 Configuring Domain Parameters
Domain IDs
Tip
If you configure an allowed list on one switch in the fabric, we recommend that you configure the same
list in all other switches in the fabric to ensure consistency or use CFS to distribute the configuration.
An allowed domain ID list must satisfy the following conditions:
• If this switch is a principal switch, all the currently assigned domain IDs must be in the allowed list.
•
If this switch is a subordinate switch, the local runtime domain ID must be in the allowed list.
• The locally configured domain ID of the switch must be in the allowed list.
•
The intersection of the assigned domain IDs with other already configured domain ID lists must not
be empty.
Configuring Allowed Domain ID Lists
To configure the allowed domain ID list, perform this task:
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 21, “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.
Command Purpose
Step 1
switch# configuration terminal
switch(config)#
Enters configuration mode.
Step 2
switch(config)#
fcdomain allowed
domain-id range
vsan vsan-id
Configures the list to allow switches with
the domain ID range in the specified VSAN.
switch(config)# no fcdomain allowed domain-id
range vsan vsan-id
Reverts to the factory default of allowing
domain IDs from 1 through 239 in the
specified VSAN.
