Specifying Static or Preferred Domain IDs

When you assign a static domain ID type, you are requesting a particular domain ID. If the switch does
not obtain the requested address, it will isolate itself from the fabric. When you specify a preferred
domain ID, you are also requesting a particular domain ID; however, if the requested domain ID is
unavailable, then the switch will accept another domain ID.
While the static option can be applied at runtime after a disruptive or nondisruptive restart, the preferred
option is applied at runtime only after a disruptive restart (see the
page
Note Within a VSAN all switches should have the same domain ID type (either static or preferred). If a
configuration is mixed (some switches with static domain types and others with preferred), you may
experience link isolation.
To specify a static or preferred domain ID, perform this task:
Command
Step 1
switch# configuration terminal
switch(config)#
Step 2
switch(config)# fcdomain domain domain-id
preferred vsan vsan-id
switch(config)# no fcdomain domain domain-id
preferred vsan vsan-id
Step 3
switch(config)# fcdomain domain domain-id
static vsan vsan-id
switch(config)# no fcdomain domain domain-id
static vsan vsan-id

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.

Purpose
Enters configuration mode.
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.
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.
