input/output counters 2950

Hey folks,

I'm wondering my interface stats are showing me "last input never" when there are clearly incrementing input packets:

FastEthernet0/10 is up, line protocol is up (connected)

Hardware is Fast Ethernet, address is 0012.43f3.6a8a (bia 0012.43f3.6a8a)

Hi,

this counter is not updated when packets are fast switched, only when packets are process switched.

So ping your router and that should reset this counter.

Hope this helps

Thanks for your reply.

Can someone please explain to me the difference between fast switched and process switched and why in this case my counter was not updated, and why it would be updated if I were to ping my switch? Thanks.
