Configuring Fibre Channel Interfaces
Note • The interface must be disabled using a shutdown command before it can be taken out of service.
• The interface cannot be a member of a PortChannel.
• Taking interfaces out of service releases all the shared resources to ensure that they are available to other
To take an interface out of service, perform these steps:
Step 1 switch# configure terminal
Enters configuration mode.
Step 2 switch(config)# interface fc 1/1
Selects the interface and enters interface configuration submode.
Step 3
switch(config-if)# no channel-group
Removes the interface from a PortChannel.
Step 4 switch(config-if)# shutdown
Disables the interface.
Step 5
switch(config-if)# out-of-service
Takes the interface out of service.
Use the show port-resources module command to verify the out-of-service configuration for interfaces on a Generation
2 and Generation 3 switching module.
This example shows a 24-port 4-Gbps module:
switch# show port-resources module 9
Module 9
Available dedicated buffers are 5429
Port-Group 1
Total bandwidth is 12.8 Gbps
Total shared bandwidth is 12.8 Gbps
Allocated dedicated bandwidth is 0.0 Gbps

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.
