Verifying installed licenses

switch# show license usage
For more information about the CLI, see the Cisco MDS 9000 Family NX-OS Fundamentals Configuration
Guide.
Modifying the FC domain ID (optional)
If the Cisco MDS 8Gb 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 it 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 command 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 static domain ID enter the command:
switch(config)# fcdomain domain 2 static vsan 237
This command 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.
To disable a port, enter the following commands:
switch# config t
switch(config)# interface ext1
switch(config-if)# shutdown
To enable a port, enter the following commands:
switch# config t
switch(config)# interface ext1
