auto port duplex option

Hi,

I have noticved that I cannot set port duplex to auto on a wsc6509 catalyst 8.3(4) Switch.

> (enable) set port duplex 2/36 ?

full Full duplex

half Half duplex

Will port duplex be in only 2 modes on all cat os switches?

Thanks,

Prakash

Prakash,

I think its true that CATOS does not allow you to set the duplex. I also think its the same across IOS platforms as well. As long as the speed is hardcoded to 10 or 100, you can change duplex settings to full or half appropriately. If speed is set to auto, it automatically negotiates both the speed and duplex settings.

Did you hardcode the speed first , usually you have to hardcode the speed first before doing the duplex . Speed cannot be auto and set the duplex too .

Hi Prakash,

u must set the speed instead of duplex first. otherwise, no matter how hard u tried, still back to square.
