Initially Configuring A Port; Configuring Port Auto-Negotiation Speed - 3Com 4210 9-Port Configuration Manual

In case of a Combo port, only one interface (either the optical port or the electrical port) is active at a
time. That is, once the optical port is active, the electrical port will be inactive automatically, and vice
versa.

Configuring Port Auto-Negotiation Speed

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.
