Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# fcdomain fcid database
switch(config-fcid-db)#
Step 3
switch(config-fcid-db)# vsan 1000 wwn
33:e8:00:05:30:00:16:df fcid 0x070128
switch(config-fcid-db)# vsan 1000 wwn

switch(config-fcid-db)# vsan 1000 wwn
11:22:11:22:33:44:33:44 fcid 0x070100 area
Unique Area FC IDs for Some HBAs
Only read this section if the HBA port and the storage port are connected to the same switch.
Note
Some HBA ports require a different area ID than storage ports when they are both connected to the same
switch. For example, if the storage port FC ID is 0x6f7704, the area for this port is 77. In this case, the
HBA port's area can be anything other than 77. The HBA port's FC ID must be manually configured to
be different from the storage port's FC ID.
Switches in the Cisco MDS 9000 Family facilitate this requirement with the FC ID persistence feature.
You can use this feature to preassign an FC ID with a different area to either the storage port or the HBA
port. The procedure in this example uses a switch domain of 111(6f hex). The HBA port connects to
interface fc1/9 and the storage port connects to interface fc 1/10 in the same switch.

Persistent FC IDs Manual Configuration
Purpose
Enters configuration mode.
Enters FC ID database configuration submode.
Configures a device WWN
(33:e8:00:05:30:00:16:df) with the FC ID
0x070128 in VSAN 1000.
To avoid assigning a duplicate FC ID, use
Note
the show fcdomain address-allocation
vsan command to display the FC IDs in
use.
Configures a device WWN
(11:22:11:22:33:44:33:44) with the FC ID
0x070123 in VSAN 1000 in dynamic mode.
Configures a device WWN
(11:22:11:22:33:44:33:44) with the FC IDs
0x070100 through 0x701FF in VSAN 1000.
To secure the entire area for this
Note
fcdomain, assign 00 as the last two
characters of the FC ID.
