Note

Taking Interfaces Out of Service

You can take interfaces out of service on Generation 2 switching modules. When an interface is out of
service, all the shared resources for the interface are released as well as the configuration associated with
those resources.
The interface must be disabled using a shutdown command before it can be taken out of service.
Note
Taking interfaces out of service releases all the shared resources to ensure that they are available to other
Caution
interfaces. This causes the configuration in the shared resources to revert to default when the interface
is brought back into service. Also, an interface cannot come back into service unless the default shared
resources for the port are available. The operation to free up shared resources from another port is
disruptive.
The interface cannot be a member of a PortChannel.
Note
To take an interface out of service, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# interface fc 1/1
switch(config-if)#
Step 3
switch(config-if)# no channel-group
Step 4
switch(config-if)# shutdown
Step 5
switch(config-if)# out-of-service
Putting an interface into out-of-service will
cause its shared resource configuration to
revert to default
