I am troubleshooting a problem with very little success. I have a VLAN located on a MSFC2. In smalls burst about every so often I see the input queue drops jump quite a bit. Any other time the queue is 0/75. I did some show commands but I'm affraid that I need some help looking through them. Below is an out put of some commands. I don't know if the cause is broadcast traffic or maybe I don't have MLS set up right. Normally we don't have a lot of traffic on our network, and I don't see any signs of bursty traffic however I keep getting alerts about my input queue on a Few of my VLANS. Please if you have any idea HELP!!!
Notice the bad hop count under the sho ip traffic command. Does this mean anything? Also check out UDP stats.

Is this a Sup1 or Sup2?? The MSFC only handles software switched packets, most packets are intended to be switched in hardware ASICs on the Supervisor. Therefore, something is causing the MSFC to get a burst of packets. What is configured under the VLAN 21 interface besides the IP address? Are you doing HSRP? Have you check to see if this may be related to Asymmetric Routing?
By default, MLS will run on the Sup1/MSFC2. Unless you have changed the config, it should be functioning correctly.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
