To configure the port speed on an interface on a 4-Gbps or 8-Gbps switching module, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# interface fc 1/1
switch(config-if)#
Step 3
switch(config-if)# switchport speed 4000
switch(config-if)# switchport speed 8000
switch(config-if)# switchport speed auto
switch(config-if)# switchport speed auto max
2000
switch(config-if)# switchport speed auto max
4000
switch(config-if)# no switchport speed
1. The 8000 and auto max 4000 speed configurations are available only for the 8-Gbps modules.
2. The default speed on 48-port and 24-port 4-Gbps modules is 4000. The defualt speed on 48-port and 24-port 8-Gbps modules is 8000.
The default speed on the 4/44-port 8-Gbps module is auto max 4000.
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.

Purpose
Enters configuration mode.
Selects the interface and enters interface
configuration submode.
Configures the port speed in megabits per
second. Valid values are 1000, 2000, 4000 and
auto. The auto parameter enables autosensing
on the interface.
(8-Gbps modules only
speed in megabits per second to 8-Gbps. Valid
values are 1000, 2000, 4000, 8000 and auto.
The auto parameter enables autosensing on the
interface.
On 4-Gbps modules, configures autosensing for
the interface with 4 Gbps of bandwidth
reserved.
On 8-Gbps modules, configures autosensing for
the interface with 8 Gbps of bandwidth
