You can configure an auto-negotiation speed for a port by using the speed auto
command.
Take a 10/100/1000 Mbps port as an example.
If you expect that 10 Mbps is the only available auto-negotiation speed of the
■
port, you just need to configure speed auto 10.
If you expect that 10 Mbps and 100 Mbps are the available auto-negotiation
■
speeds of the port, you just need to configure speed auto 10 100.
If you expect that 10 Mbps and 1000 Mbps are the available auto-negotiation
■
speeds of the port, you just need to configure speed auto 10 1000.
