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:
Enabling Bandwidth Fairness
Detailed Steps
To enable bandwidth fairness on a switching module, follow these steps:
Command Purpose
Step 1
switch# config t
switch(config)#
Enters configuration mode.
Step 2
switch(config)# interface fc2/1-2,
fc2/4-5, fc2/8-38, fc2/43-48
Specifies the port interfaces for which you want to
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
module 1
Enables restrictions on oversubscription ratios for
the module.
Note You must enter this command separately for
each module for which you want to add the
restriction.
switch# config t
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
Returns all shared ports to service.
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.
Command Purpose
Step 1
switch# config t
switch(config)#
Enters configuration mode.
Step 2
switch(config)# rate-mode
bandwidth-fairness module 1
Enables bandwidth fairness for a module.
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.
