Hi ST,


With command show int vlan "vlan number" you can see the avg. time of 5 min for input and output counters in bots/sec or you can try with sofwtare like MRTG or PRTG see if you can see the SVI interface utilization.


Hope to Help !!

You'll need to clear the counters using the command  "clear count ".


Next is the command "sh interface " and observe the line "Last clearing of "show interface" counters".  Next you look at the "packets input" and "packets output".


Is this what you are looking for?

Hi,


If you have created SVI for vlan 99 then you can try with show int vlan 99 to see the amount of traffic in and out via that vlan interface.
