Setting the Speed of Ethernet Interfaces

To discover whether the remote and local interface requires manual speed synchronization, and to manually synchronize them if necessary, use the following command sequence.

  1. Determine the local interface status. Refer to the following example.
    EXEC Privilege mode
    show interfaces [interface | stack—unit stack-unit-number] status
  2. Determine the remote interface status.
    EXEC mode or EXEC Privilege mode
    [Use the command on the remote system that is equivalent to the first command.]
  3. Access CONFIGURATION mode.
    EXEC Privilege mode
    config
  4. Access the port.
    CONFIGURATION mode
    interface interface-type
  5. Set the local port speed.
    INTERFACE mode
    speed {10 | 100 | 1000 | 10000 | auto}
    NOTE If you use an active optical cable (AOC), you can convert the QSFP+ port to a 10 Gigabit SFP+ port or 1 Gigabit SFP port. You can use the speed command to enable the required speed.
  6. Optionally, set full- or half-duplex.
    INTERFACE mode
    duplex {half | full}
  7. Disable auto-negotiation on the port.
    INTERFACE mode
    no negotiation auto
    If the speed was set to 1000, do not disable auto-negotiation.
  8. Verify configuration changes.
    INTERFACE mode
    show config

Example of the show interfaces status Command to View Link Status

NOTE The show interfaces status command displays link status, but not administrative status. For both link and administrative status, use the show ip interface command.

[output omitted]

In the previous example, several ports display “Auto” in the Speed field. In the following example, the speed of port 1/1 is set to 100Mb and then its auto-negotiation is disabled.
