Chapter 3 Configuring Fibre Channel Interfaces

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

Speed is 2 Gbps Rate mode is shared Transmit B2B Credit is 64 Receive B2B Credit is 16 Receive data field Size is 2112 Beacon is turned off

5 minutes input rate 0 bits/sec, 0 bytes/sec, 0 frames/sec

5 minutes output rate 0 bits/sec, 0 bytes/sec, 0 frames/sec 226 frames input, 18276 bytes

0 discards, 0 errors

0 CRC, 0 unknown class

0 too long, 0 too short

326 frames output, 21364 bytes

0 discards, 0 errors

0 input OLS, 0 LRR, 1 NOS, 0 loop inits

3 output OLS, 2 LRR, 0 NOS, 0 loop inits 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
Step 1	switch# config t	Enters configuration mode.
	switch(config)#
Step 2
Step 2	switch(config)# interface fc 1/1	Selects the interface and enters interface
	switch(config-if)#	configuration submode.
