I have implemented VACLs in my environment to overcome the limitation of having only 2 span ports on a 6500 series switch. I have used up the availble 2 ports for spannign traffic for some other applications.
I am using VACLs specifically for capturing traffic and forwarding it to a capture port. In my setup what I see is that I am seeing only one way traffic for the vlan that I have setup in my capture. This is different than a span port as on a span port I was seeing traffic to/from vlan or an individual port. Is this by design and if it is, my question is what is it getting someone by seeing one way traffic. It does not make sense to me why anyone would like to see one way traffic....am i missing something.
I would really appreciate if someone can clarify this for me.
Thanks in advance
