I am running wireshark version 1.6.6 on a Dell Latitude E6400. I am pretty sure the packets are getting to the NIC on the wireshark host because of link light activity, but still can't see them in wireshark. When hooked to the 10baseT hub, I can see (while transmitting) that there is high activity on all three ports (console, IP223 and wireshark) but there isn't any multicast traffic showing up. I can see (sniff) the normal traffic like spanning tree, arp and the constant pings (unicast) the console does to make sure they are in contact with the radio, but I still don't see the multicast. I have also tried a connection to a 10baseT hub (repeater, not a switch) without any multicast traffic showing up. The radio and console work correctly over the switch and IP-223.īesides looking for the multicast on a regular port, I have tried mirroring the port and VLAN, and connecting the console (and radio) directly into the wireshark ethernet port. I have simplified the network to a minimum configuration for troubleshooting, so I have a radio console connected to a Linksys SF300-24 switch, connected to the Telex IP-223 (radio controller), then connected to the radio. I am trying to make sure the traffic is getting out to the carrier network. I have a Telex Radio over IP multicast network and have had trouble getting it to pass over a carrier's ethernet link.

Wireshark capture multicast traffic
