Chapter 3 Configuring Fibre Channel Interfaces

Configuration Examples for Fibre Channel Interfaces

Step 1 Select interfaces fc 3/1.

switch# config t

switch(config)# interface fc 3/1

Step 2 Configure the port speed, rate mode, and port mode on the interfaces.

switch(config-if)#switchport speed 8000 switch(config-if)#switchport rate-mode dedicated

switch(config-if)# switchport mode f

Step 3 Enable the interfaces and return to configuration mode.

switch(config-if)# no shutdown switch(config-if)# exit switch#

Step 4 Select the interfaces fc 3/2 through fc 3/3.

switch# config t

switch(config)# interface fc 3/2 - 3

Step 5 Configure the port speed, rate mode, and port mode on the interfaces.

switch(config-if)#switchport speed 8000

switch(config-if)#switchport rate-mode shared

switch(config-if)# switchport mode f

Step 6 Enable the interfaces and return to configuration mode.

switch(config-if)# no shutdown switch(config-if)# exit switch#

Configuration Example for 4/44-Port 8-Gbps Module Interfaces

These steps describe how to configure the 4/44-port 8-Gbps module interfaces:

Step 1 Select interfaces fc 4/11 through fc 4/12.

switch# config t

switch(config)# interface fc 4/11 - 12

Step 2 Disable the interfaces and take them out of service.

switch(config-if)# shutdown switch(config-if)# out-of-service

Step 3 Return to configuration mode.

switch(config-if)# exit switch#

Step 4 Select the interfaces fc 4/1.

switch# config t

switch(config)# interface fc 4/1

Step 5 Configure the port speed, rate mode, and port mode on the interfaces.

switch(config-if)#switchport speed 8000
