Chapter 3 Configuring Fibre Channel Interfaces

Configuring Fibre Channel Interfaces

Detailed Steps

To enable restrictions on oversubscription ratios on a 48-port or 24-port 4-Gbps, or any 8-Gbps Fibre Channel switching module, follow these steps:

	Command	Purpose
Step 1
	switch# config t	Enters configuration mode.
	switch(config)#
Step 2
	switch(config)# interface fc2/1-2,	Specifies the port interfaces for which you want to
	fc2/4-5, fc2/8-38, fc2/43-48	enable restrictions on oversubscription ratios.
Step 3
	switch(config-if)# shutdown	Shuts down shared ports.
Step 4
	switch(config-if)# out-of-service	Takes shared ports out of service.
Step 5
	switch# rate-mode oversubscription-limit	Enables restrictions on oversubscription ratios for
	module 1	the module.
		Note	You must enter this command separately for
			each module for which you want to add the
			restriction.
	switch# config t	Returns all shared ports to service.
	switch(config)# interface fc2/1-2,
	fc2/4-5, fc2/8-38, fc2/43-48
	switch(config-if)# no out-of-service
	switch(config-if)# no shutdown
Step 6
	switch(config)# exit	Exits configuration mode.
Step 7
	switch# copy running-config startup-config	Saves the new oversubscription ratio configuration
		to the startup configuration, and then the new
		configuration is enforced upon subsequent reboots
		of the module.

Enabling Bandwidth Fairness

Detailed Steps

To enable bandwidth fairness on a switching module, follow these steps:

	Command	Purpose
Step 1
	switch# config t	Enters configuration mode.
	switch(config)#
Step 2
	switch(config)# rate-mode	Enables bandwidth fairness for a module.
	bandwidth-fairness module 1	Note You must enter this command separately for
		each module for which you want to enable
		bandwidth fairness. You must reload the
		module for the command to take effect.
Step 3
	switch(config)# exit	Exits configuration mode.
