Overview
This command changes the speed of the specified port. You can optionally specify
the speed or speeds that get autonegotiated, so autonegotiation is only
attempted at the specified speeds.
To see the currently-negotiated speed for ports whose links are up, use the
interface
default), use the
speed {10|100|1000|auto [10][100][1000]}
Syntax
The following table shows the speed options for each type of port.

Default
By default, ports autonegotiate speed.
Usage
Switch ports in a static or dynamic (LACP) channel group must have the same port
speed and be in full duplex mode. Once switch ports have been aggregated into a
channel group, you can set the speed of all the switch ports in the channel group
by applying this command to the channel group.
NOTE
then the device only attempts autonegotiation at those specified speeds.
Examples
To set an SFP to a fixed speed of 1000Mbps, enter the following commands:
awplus#
awplus(config)#
awplus(config-if)#
To return the port to auto-negotiating its speed, enter the following commands:

awplus(config)#
awplus(config-if)#
