Cisco MDS 9124e Fabric Switch for HP c-Class BladeSystem 25
Modifying the FC domain ID (optional)
If desired, you can modify the domain ID. If the Cisco MDS 9124e Fabric Switch is not powered on
until after it is connected to the fabric and the default FC domain ID is already in use, the domain ID
for the new switch is automatically reset to a unique value. If the switch is connected to the fabric
after is has been powered on and the default domain ID is already in use, the fabric segments.
Use the show fcdomain address-allocation command to display domain ID allocation
statistics, including a list of assigned domain IDs.
To modify a preferred domain ID enter the command:
switch(config)# fcdomain domain 3 preferred vsan 8
This configures the switch in VSAN 8 to request a preferred domain ID 3 and accepts any value
assigned by the principal switch. The domain range is 1 to 239.
To modify a preferred domain ID enter the command:
switch(config)# fcdomain domain 2 static vsan 237
Configures the switch in VSAN 237 to accept only a specific value and moves the local interfaces in
VSAN 237 to an isolated state if the requested domain ID is not granted.

use this command:
switch# config t
switch(config)# interface ext1
switch(config-if)# shut
switch(config-if)# port-license acquire
Disabling and enabling a port
Use the shutdown and no shutdown commands to disable and enable ports. The following
shows how to enter the shutdown command:
switch# config t
switch(config)# interface ext1
switch(config-if)# shutdown
The following shows how to enter the no shutdown command:
switch# config t
switch(config)# interface ext1
