Switch 4948 input/output traffic =0 with traffic trought it

Hi, I've a problem with a port of this switch. This port is completely operational, but the counters of input/output traffic is in Zero. I have a lot of traffic on it (+- 48 Mbps this I can see with MRTG), but I don't know why the counters are in zero. The port is routing, no switching.

Re: Switch 4948 input/output traffic =0 with traffic trought it

Hello Juan,

I see that the cumulative counters are non-zero while rate counters are 0.

You can think of this as a cosmetic issue if the port is working correctly.

This can come from the multilayer action of the switch that bypasses the counters: it was so for example on C6500 in Hybrid mode.

Why happens only for one port is the strange part of the problem.

Hope to help

Giuseppe
