Modifying the FC domain ID optional | Cisco Systems 9124E manual

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-allocationcommand 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.

On Demand Ports

Use the interface command to enable On-Demand Ports. The following example shows how to 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

switch(config-if)# no shutdown
