Not that I know of and I think a lot of people would like that feature in all their switches. I also would like the same function in the 4500 and 6500 as say a 3750 or a 2960 which is the "show controllers utilization " command . This gives you an instant look at the utilization percentage on all ports along with the switch fabric utilization . Very useful but they don't put it in their modular boxes , might be a hardware restriction but it would be nice to have an equivalent for the modular boxes.

Hi


If I do a sh interface I get this line:


Last input 20w3d, output 15w2d, output hang never


Dos that mean that this port has not been used for 15 weeks and 2 days OR 20 weeks and 3 days?

clearly that interface didnt got any input traffic since 20 week 3 days and didnt send anything from it till 15 week 2 days,or not used till these period for each direction..

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