Throttles on VLAN

With the key word of "throttle" you seem to get everyone's interface statistics and never the information you're looking for.

So I'm asking here, why are we getting so many throttles on our VLANs?

Vlan1 is up, line protocol is up

Re: Throttles on VLAN

You're also showing a very high number of input queue drops and flushes. What hardware platform are you running? Are any QoS policies defined?
