IP statistics, cocnerning high number of IP packets labelled as "with options"

Hello,

I would like to understand the reason behind getting so many packages labeled as " with options"  and " alerts" in my switch. As you can see in the IP traffic below:

  Rcvd: 6451839 requests, 244 replies, 0 reverse, 0 other

  Sent: 220 requests, 6078 replies (0 proxy), 0 reverse

  Drop due to input queue full: 0

The switch has a multicast camera attached to it, being it the one which is generating almost all the traffic on the network. How can I make that label go away?

Thanks in advance,

regards!
