Hi folks,
Does anybody know what causes the router to drop packets as
overrun and what as an input queue drops. There are two show interface
examples of NPE-G1, both with input hold-queue set to 4096. The first
one only shows 153 overrun packets, in the second interface output
you can see

Drew,
Overruns are usually caused by the receiving hardware buffer being flooded
for lack of a better term because the input rate exceeded the receiver's
ability to handle the traffic.

Hi,
I noticed I'm seeing some Input errors on a gigabit ethernet interface:
70 input errors, 0 CRC, 0 frame, 70 overrun, 0 ignored
the number of input errors seems to increment along with the overrun counter
which I assume means that the actual errors are overrun errors.
Nah this particular instance it is one interface in a 3GE-GBIC-SC in a GSR.
thanks,

Thanks for responding,
As far as you're aware is there a way to check the hardware

Unfortunately I don't know of anyway to check the hardware buffer(s), and my
guess is per line card.
I would also run a show process cpu while the overruns incrementing (if you
can) to see if the utilization is above 90%. I've

Hardware too slow error - packets arrive in short bursts at line rate,
and your router cannot handle that.
For example, an NPE-G1 will handle packets at,

There's not much you can do, except get a hardware forwarding box
or just accept it, and only worry if
