Examples

address-allocation

Displays statistics for the fcid allocation

 

 

cache

The cache is used by the principle switch to reassign the FC IDs for a

 

device (disk or host) that exited and reentered the fabric. In the cache

 

content, VSAN refers to the VSAN that contains the device, WWN refers

 

to the device that owned the FC IDs, and mask refers to a single or entire

 

area of FC IDs.

 

 

allowed

Displays a list of allowed domain IDs.

 

 

domain-list

Displays list of domain ids granted by the principal sw

 

 

fcid persistent

Displays persistent FCIDs (across reboot)

 

 

statistics interface

Displays the statistics of fcdomain

 

 

fc slot/port

Specifies a Fibre Channel interface.

 

 

fcip fcip-id

Specifies an FCIP interface. The range is 1 to 255.

 

 

iscsi slot/port

Specifies an iSCSI interface.

 

 

vsan vsan-id

Specifies a VSAN ID. The range is 1 to 4093).

 

 

None.

 

EXEC mode.

 

This command was introduced in Cisco MDS SAN-OS Release 1.0(2).

Issuing the show fcdomain with no arguments displays all VSANs. The VSANs should be active or you will get an error.

The following example displays the fcdomain information for VSAN 1.

switch# show fcdomain vsan 1

The local switch is a Subordinated Switch.
