Configuring Fibre Channel Interfaces
Use the show interface command to verify the port speed configuration for an interface on a 4-Gbps or
8-Gbps Fibre Channel switching module.
switch# show interface fc 9/1
fc9/1 is up
Hardware is Fibre Channel, SFP is short wave laser w/o OFC (SN)
Port WWN is 22:01:00:05:30:01:9f:02
Admin port mode is F
snmp traps are enabled
Port mode is F, FCID is 0xeb0002
Port vsan is 1

16 receive B2B credit remaining
64 transmit B2B credit remaining
Configuring Rate Mode
Restrictions
• Changing port speed and rate mode disrupts traffic on the port.
Detailed Steps
To configure the rate mode (dedicated or shared) on an interface 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
switch(config)#
Enters configuration mode.
Step 2
switch(config)# interface fc 1/1
switch(config-if)#
Selects the interface and enters interface
configuration submode.
