Configuring Interface Characteristics

Configuring Ethernet Interfaces

Setting the Interface Speed and Duplex Parameters

SUMMARY STEPS
1. configure terminal
2. interface interface-id
3. speed {10 | 100 | 1000 | auto [10 | 100 | 1000] | nonegotiate}
4. duplex {auto | full | half}
5. end
6. show interfaces interface-id
7. copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1 configure terminal
Example:
Switch# configure terminal
Step 2 interface interface-id
Example:
Switch(config)# interface
gigabitethernet1/0/3
Step 3 speed {10 | 100 | 1000 | auto [10 | 100 |
1000] | nonegotiate}
Example:
Switch(config-if)# speed 10

Purpose
Enters global configuration mode.
Specifies the physical interface to be configured, and enter interface
configuration mode.
This command is not available on a 10-Gigabit Ethernet interface.
Enter the appropriate speed parameter for the interface:
• 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
