Re: [Aironet] Multicast

[<lo...@pe...>]

Rob,

Can you desribed the upstream equipment which is in use at the 'bottom' of
the hill? What I'm curious about is the possibility of some sort of ARP
traffic being generated, or, a router attempting to reach a station by
addressing frames at a mcast address. 

Also, have do you have the ability to attach some sort of packet capturing
tool to the network? Something as simple as a *nix box running "ngrep" or
"tcpdump" would do. I'd recomend looking into where/what is generating
these mcast packets.

Hope the ideas help!
