Hi all.

We have sporadicaly performance impacts in our network. We notice massive "out discards" on several ports. 71G and 71K Series.
I have the same question as Zdenek.

What does cause an "out discard"?
TXQ overflow? Port buffer overflow?

Thanks and regards
Alex

I would suggest you look at the ‘show port flowcontrol’ counters.  To see if you are receiving a large number of pause frames on the ports from the end device.
