Configuring Port Speed - Cisco MDS 9000 Series Configuration Manual

Configuring Port Speed

Step 5
Configure the traffic speed (1 Gbps, 2 Gbps, 4 Gbps, or autosensing with a maximum of 2 Gbps or 4 Gbps) to use.
See the Dynamic Bandwidth Management, on page
Configuring Port Speed
Note Changing port speed and rate mode disrupts traffic on the port. Traffic on other ports in the port group is not
affected.
To configure the port speed on an interface, 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 speed {1000 | 2000 | 4000 | 8000 | 10000 | 16000 | 32000}
Configures the port speed in megabits per second. The auto parameter enables autosensing on the interface.
Step 4
switch(config-if)# switchport speed auto
Configures autosensing for an interface.
The auto speed configurations are available only for the specific modules.
Note
Step 5 switch(config-if)# no switchport speed
Reverts to the default speed for the interface (auto).
Use the show interface command to verify the port speed configuration for an interface.
switch# show interface fc 9/1
