Hi, easy one for someone who knows how.
Basically I need to change the network port and duplex speed to auto and auto.
I need to change port Gi2/0/27. checked online and tried several commands but must be doing something wrong.

Thanks a lot

It is set to auto/auto already as indicated by the a-full and a-100 with the "a-" referencing 100/Full determined by auto negotiation.

Ok but If I wanted to make a change?, as some are listed as just auto and some auto 100, the current setup is making the printer run painfully slowly and I need to find a port speed that will work.

The difference is the ones that say "auto auto" are ports with nothing plugged into them.  The ones that have something plugged into it say "a-100 and a-full".  Are there errors on port?

Thanks, there are no errors on the port. The printer only starting becoming slow when we changed from Hp to Cisco switches recently. The jetdirect card is set to auto. Have tried directly connecting the printer to the switch as well, also created local ports on the IP to bypass the print server, still very slow.

If i change the jetdirect card on the printer to 100FDx, the switch port changes to 100HDx?

Worth forcing the port to 100 FULL (no auto)?
