Cisco Systems DSC9148D8G48PK9 Releasing Shared Resources in a Port Group, Disables the interface

Chapter 3 Configuring Fibre Channel Interfaces

Configuring Fibre Channel Interfaces

	Command	Purpose
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.
	Putting an interface into out-of-service will
	cause its shared resource configuration to
	revert to default
	Do you wish to continue (y/n)? [n] y

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

fc9/1	16	4.0	shared
fc9/2 (out-of-service)

fc9/6	16	4.0	shared

Releasing Shared Resources in a Port Group

When you want to reconfigure the interfaces in a port group on a Generation 2 or Generation 3 module, you can return the port group to the default configuration to avoid problems with allocating shared resources.

Restrictions

•The interface cannot be a member of a PortChannel.

•Releasing shared resources disrupts traffic on the port. Traffic on other ports in the port group is not affected.
