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
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.

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