Hi all,
We have 6509 CatOS switch which has port 3/4 and 4/4 as Trunk Ports.
I did sh top util and found that trunk ports have over flow of 2977 and 18384
sh top util

4/3 1000 6 505162023 436374 383 146 0 0
So what does over flow mean.
Is it some type of error on switch?
many thanks

Buffer Overflow means that the port receivesg more traffic than it can store in its buffer. This can be caused a bursty traffic, as well an overrun of buffers. The suggested action is to decrease the transmission of the source device.
If its just very slowly incrementing its probably not a problem and just due to bursty traffic , clear the counters and keep an eye on it for a few days.

Hi glen,
thanks for reply.
I cleared the counters still it is increasing
rapidly so i can ignore this as it is not serious issue?
Thanks
