understanding traffic

Thu Sep 13, 2012 11:09 pm

Hello I have an WISP with this architecture:

| -----
|------
----RB1000------cisco2960--- |------
|------


where the RB 1000 is a pppoe server connected to the cisco switch and then every nodes are conected to the same switch, APs and SMs are mikrotik.

THE PROBLEM I HAVE IS THAT: if i connect directly with a pc to the cisco and i start sniffing with wireshark i have traffic in the port i´m connected to, this traffic is not from/for me. This traffic is not broadcast mac, multicast mac, broadcast ip or multicast ip. I have no loops in the switch so I dont understand why is present this traffic. I have more or less 200 wireless clients.

Suggestions??

Thanks in advance

figure out. what is this traffic? From where? to what? Its common to have some kind of traffic in a big "bridged" l2 net like you have here. How about another MS computer in the same l2 net?
