DETAILED STEPS
PurposeCommand or Action
Enables privileged EXEC mode. Enter your password if prompted.enable
Step 1
Example:
Switch> enable
Enters global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 2
Specifies the physical interface to be configured, and enter interface
configuration mode.
interface interface-id
Example:
Switch(config)# interface
Step 3
gigabitethernet1/0/3
Enter the appropriate speed parameter for the interface:speed {10 | 100 | 1000 | 2500 | 5000 | 10000 |
auto [10 | 100 | 1000 | 2500 | 5000 | 10000] |
nonegotiate}
Step 4
•
Enter 10, 100, 1000 2500, 5000, or 10000 to set a specific speed
for the interface.
Example:
Switch(config-if)# speed 10
•
Enter auto to enable the interface to autonegotiate speed with
the connected device. If you specify a speed and also set 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 to not negotiate if connected to a device that does
not support autonegotiation.
This command is not available on a 10-Gigabit Ethernet interface.duplex {auto | full | half}
Step 5
Example:
Switch(config-if)# duplex half
Enter the duplex parameter for the interface.
Enable half-duplex mode (for interfaces operating only at 10 or
100 Mb/s). You cannot configure half-duplex mode for interfaces
operating at 1000 Mb/s.
You can configure the duplex setting when the speed is set to auto.
Returns to privileged EXEC mode.end
Example:
Switch(config-if)# end
