Tcpdump pcap wireshark10/30/2023 ![]() ![]() ![]() You can manually parse through the data there, but it is a heck of a lot more convenient if Wireshark does that. What I am referring to is that Wireshark does not show me the ARP packet that is in the highlighted region (this particular screenshot shows a corrupted ARP packet, but the behavior is the same on pristine payload.) Instead of showing a "ARP" packet in the tree and allowing me to browse through the fields of the ARP packet, it just shows "QoS Data". If you'll look at the screenshot I posted you'l notice that the trace is indeed from a controller-side/ERM capture, and that the payload traffic is not encrypted. If you want to capture a 80mhz channel (802.11ac AP required), you would do this: If you want to capture a 40mhz channel you would do this: This is what I see from wireshark on my mac: The number after Radio must be 0 if I am capturing 5ghz and 1 if I am capturing 2.4ghz:Īp packet-capture raw-start ap-name Office-135 192.168.1.72 5555 0 radio 0 5555 matches the ERM port I am using in wireshark. The ip address (.72) is the ip address of my wired laptop. Below the AP-Name is the name of the Air monitor. Next, I need to stream all of the traffic from that access point on that radio to the wired laptop. 116 tuned to channel 161 (more on how to capture 40mhz and 80 mhz channels later) Below I have the air monitor with the ip address of. To start a packet capture, first you need to tune the AM so that it is only capturing on the channel you want it to. ![]() On the commandline of the controller, you will need (1) The ip address of the air monitor (2) the channel you want to capture on (3) the ip address of the wired laptop. in the filter box, just like you typed, type "aruba_erm" so that we only get Aruba packet capture traffic. Next, setup wireshark to do a packet capture on the wired interface of that laptop. Secondly, make sure the device you are capturing is an AM Wired connectivity between the Air Monitor and the Wired Laptop.įirst, make sure the version of wireshark has the Aruba ERM:Įdit> Wireshark Preferences => Protocols => Aruba ERM.
