Hi all,
Can someone please tell me how I turn off flow control on a gigabitethernet interface in a 2851 series router. Software is Version 12.4(3d).
The output of show int gi0/0 shows that output flow-control. See below output:
Thanks for any help!

Hi Thomas,
I appreciate the response, however I don't get an option of flowcontrol on the interface :(
here is the output..
2851-rtr(config)#int gi0/0
2851-rtr(config-if)#no flowcontrol
^
% Invalid input detected at '^' marker.
Any other suggestions? Thanks for your help, this problem is proving difficult to overcome.

Hello Brad,
I've verified I have a similar condition on GE ports of C7200VXRs with NPE-G2 and 12.4(20)T but I don't see any issue in my network.
Also from the sh interface you provided flow control is based on IEEE pause frames but your pause frames counters are 0 input and output.
It looks like flowcontrol never took place
What problem do you think is related to flowcontrol in your scenario ?
Hope to help
Giuseppe
