No input and output


I see the last input and 30 sencond input and output as 0.

What my understandinig is since CEF is enabled the packet are not hitting the CPU and thats why i dont see any input and output.

Is that right or i am missing something.

Re: No input and output

If you have traffic on the interface you should see input and output rate regardless of cef. Do a clear counters, put on a extended ping on the connected equipment on that interface and you should see the rate.

Re: No input and output

Hi Gunnar,

Thanks for the reply.

I have done that and there is traffic but i only see increase in L3 packets no increase in Input and output , any idea why is this happenning.
