OUIs and MAC addresses may be colon-, hyphen-, or. Finish setting up MAC address helper maci.SetType (ns3::StaWifiMac. Type or paste in a list of OUIs, MAC addresses, or descriptions below. Wiresharks captured packet data can be used to generate a variety of graphs. It uses the Wireshark manufacturer database, which is a list of OUIs and MAC addresses compiled from a number of sources. (I'm assuming the traffic you are looking for is traveling to a destination on another switch, outside the network, or at least to your gateway).īy specifying the MAC address filter, eth.addr eq xx:xx:xx:xx:xx:xx you are filtering for all traffic to and from that associated MAC address. The Wireshark OUI lookup tool provides an easy way to look up OUIs and other MAC address prefixes. You can analyze this file using tcpdump or wireshark. It will create a file in the main directory of ns3. PointToPointHelper p2p p2p.EnablePcapAll ('filename') //filename without. If you are trying to trace MAC's on the switch you are also connected to, then you'll want to sniff from a port which is spanned/mirrored to the port which has inbound/outbound traffic of that switch, so that you will see all the traffic coming in and out of the switch. I assume you need the following lines of code. the Wireshark logs as originating from the MAC ad- ent in most real networks.
For instance, tshark -i 1 -R "eth.addr eq xx:xx:xx:xx:xx:xx or eth.addr eq xx:xx:xx:xx:xx:xx" Simulated nodes, running inside ns-3, use self-generated MAC addresses by. I believe it is a similar issue to the one below. I have searched for 00:00:00:00:00:00 mac on all the switches to see if there was a single or multiple devices causing this issue. You can use a list for your MAC's in one display filter, but not a range, unless you switch to IP's instead of MAC's. 1 1 1 1 Our network is being flooded by these types of packets. If you are using a display filter of eth.addr = xx:xx:xx:xx:xx:xx and you are not seeing any information being displayed/sniffed, then the traffic for that MAC address is not passing through the port you're sniffing on.
