Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

PurposeCommand or Action
Configures the switch in the specified VSAN to accept
only a specific value and moves the local interfaces in
switch(config)# fcdomain domain
domain-id static vsan vsan-id
Step 2
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.
switch(config)# no fcdomain domain
domain-id static vsan vsan-id
Step 3
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.
switch(config)# fcdomain domain
domain-id preferred vsan vsan-id
Step 4
Resets the configured domain ID to 0 (default) in the
specified VSAN. The configured domain ID becomes
0 preferred.
switch(config)# no fcdomain domain
domain-id preferred vsan vsan-id
Step 5
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
empty.
Configuring Allowed Domain ID Lists
To configure the allowed domain ID list, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Configures the list to allow switches with the
domain ID range in the specified VSAN.
switch(config)# fcdomain allowed
domain-id range vsan vsan-id
