Hi,
I am having issue on my 3750G gig interface, it is not passing data more than 200M.Some how its giving me lots of input Pause on both sides,can some one explain if there is congesstion issue,do I need to enable flow control on both sides?

Hi,
The interface keepalive is not set. Your interface maybe up/up but it could be spoofing. Set the interface keepalive to 10 seconds

Hi,
thanks,I will set the keepalive to 10 sec, but the interface is always up and passing data all the time, I am worried why its showing lots of input pause ?

Hi,
Let us know what is connected to this gig interface.
To slow down the received traffic rate, that end device is sending the pause signal to this port, indicating the port to slow down/pause the traffic.
There is nothing wrong with this switch port. Enable the input flow control at this port if possible and observe the results.
Hope this helps.
