DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
Specifies the physical interface to be configured, and enter interface
configuration mode.
interface interface-id
Example:
Switch(config)# interface
Step 2
gigabitethernet1/0/3
This command is not available on a 10-Gigabit Ethernet interface.speed {10 | 100 | 1000 | auto [10 | 100 |
1000] | nonegotiate}
Step 3
Enter the appropriate speed parameter for the interface:
Example:
Switch(config-if)# speed 10
•
Enter 10, 100, or 1000 to set a specific speed for the interface. The
1000 keyword is available only for 10/100/1000 Mb/s ports.
•
Enter auto to enable the interface to autonegotiate speed with the
connected device. If you use the 10, 100, or the 1000 keywords with
the auto keyword, the port autonegotiates only at the specified
speeds.
•
The nonegotiate keyword is available only for SFP module ports.
SFP module ports operate only at 1000 Mb/s but can be configured
