Configuring Rate Mode

Note Changing port speed and rate mode disrupts traffic on the port.
To configure the rate mode (dedicated or shared) on an interface on a Fibre Channel switching module, 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)# switchport rate-mode dedicated
Reserves dedicated bandwidth for the interface.
If you cannot reserve dedicated bandwidth on an interface, you might have exceeded the port group maximum
Note
bandwidth. Use the show port-resources command to determine what resources are already allocated.
Step 4
switch(config-if)# switchport rate-mode shared
Reserves shared (default) bandwidth for the interface.
Step 5 switch(config-if)# no switchport rate-mode
Reverts to the default state (shared).

Disabling Restrictions on Oversubscription Ratios

Note
Before disabling restrictions on oversubscription ratios, ensure that you have explicitly shut down shared
ports.
To disable restrictions on oversubscription ratios on a Fibre Channel switching module, perform these steps:
Step 1 switch# configure terminal
Enters configuration mode.
