#Ns3 wireshark mac address for mac#
Like the MAC address, The LLC logical link control protocol is also layer 2, but is upper sublayer of Data Link Layer and won't affect the ability to capture the traffic unless you specify llc as a filter and there isn't any llc traffic, then you would get the blank screen. 2 Answers Sort by oldest newest most voted 1 answered Mar 12 '18 Jim Aragon 7512 7 70 128 Fairfield, California updated Mar 12 '18 You said, 'I want to capture all traffic from devices with MAC address containing 00:0C:22.' You probably can't create a capture filter for MAC addresses containing 00:0C:22 anywhere in the MAC address fields. But as always, the best solution to these types of questions lies in reading the manual.
When you start typing, Wireshark will help you autocomplete your filter. For example, type dns and you’ll see only DNS packets. The most basic way to apply a filter is by typing it into the filter box at the top of the window and clicking Apply (or pressing Enter). (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. you can open pcap trace files using wireshark either from the command line, ie: 'wireshark file.pcap' or open the file using the GUI interface. That’s where Wireshark’s filters come in. 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. 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" 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.

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. Ns-3 offers multi-RAT simulation capabilities, with Wi-Fi, LTE (LTE-Advanced (LTE-A), License Assisted Access (LAA), LTE-Unlicensed (LTE-U)), and Wireless Gigabit (WiGig). In a more complicated network with multiple access points (an 'extended service set'), access points may forward packets to each other, in which case all four addresses could be set, with wlan.ta being the MAC address of the sending access point and wlan.ra being the MAC address of the receiving access point.
