Port Speed, Duplex Mode, And Polarity; How To Set The Speed - Allied Telesis AT-x900-12XT/S Configuration Manual

Port speed, duplex mode, and polarity

In most networks, you will not need to change the port speed, duplex mode, or polarity,
because the ports automatically negotiate suitable settings.
This section describes how to change them, if you need to.
Enter All three are interface settings, so you first enter Interface Configuration mode for the port
Interface or port range you want to configure, by entering one of the commands:
mode
awplus(config)#interface portx.y.z
awplus(config)#interface portx.y.z-x.y.z
The prompt changes to:
awplus(config-if)#

How to set the speed

The following table shows the speed options for each type of port.
Port type
non-SFP RJ-45 copper ports
supported tri-speed copper SFPs
100Mb fibre SFPs
1000Mb fibre SFPs
XFP modules
To change the speed, first enter Interface Configuration mode for the port or port range you
want to configure. Then enter the command:
awplus(config-if)#speed <value>
For example, to set the speed of a tri-speed port to 100Mbps, enter the command:
awplus(config-if)#speed 100
To return the port to autonegotiating its speed, enter the command:
awplus(config-if)#speed auto
