About Allowed Domain ID Lists
By default, the valid range for an assigned domain ID list is from 1 to 239. You can specify a list of ranges
to be in the allowed domain ID list and separate each range with a comma. The principal switch assigns domain
IDs that are available in the locally configured allowed domain list.
Use allowed domain ID lists to design your VSANs with nonoverlapping domain IDs. This helps you in the
future if you need to implement IVR without the NAT feature.
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

To configure the allowed domain ID list, perform this task:
Procedure

OL-16597-01
Command or Action
switch(config)# fcdomain domain
domain-id static vsan vsan-id
switch(config)# no fcdomain domain
domain-id static vsan vsan-id
switch(config)# fcdomain domain
domain-id preferred vsan vsan-id
switch(config)# no fcdomain domain
domain-id preferred vsan vsan-id
empty.
Command or Action
switch# configuration terminal
switch(config)# fcdomain allowed
domain-id range vsan vsan-id
Purpose
Configures the switch in the specified VSAN to accept
only a specific value and moves the local interfaces in
the specified VSAN to an isolated state if the requested
domain ID is not granted.
Resets the configured domain ID to factory defaults in
the specified VSAN. The configured domain ID
becomes 0 preferred.
Configures the switch in the specified VSAN to request
a preferred domain ID 3 and accepts any value assigned
by the principal switch. The domain is range is 1 to 239.
Resets the configured domain ID to 0 (default) in the
specified VSAN. The configured domain ID becomes
0 preferred.
Purpose
Enters configuration mode.
Configures the list to allow switches with the
domain ID range in the specified VSAN.
