It should autosense the speed.

if that doesnt work go into interface config mode

and set the speed to 10 duplex to half

config t

int fasthernet xx (slot #)

speed 10

duplex half

ctrl z

write mem

The 'speed' is't on option.

There's a 'half-duplex' command, but no 'speed'.

I'm on 12.0

Your interface must be 10 meg only. Do a show hardware. If it says fastethernet and you can't set speed you have a problem for the TAC.

Just checked the specs (fwiw) that ethernet is supposed to be 10/100 autosense. May need to call the TAC on this one

The FastEthernet interface on 1700 series routers will run at 10 or 100 Mbps. However, prior to some 12.1 or 12.2 (sorry I can't remember which) code, the interface is autosense only.

I have 1720s in my lab running various 12.1 and all can be configured manually so it must be prior to most 12.1. Thanks.
