You can search access points either by name or serial number. For example, you can use wlan or tzsp & !(icmp) as a filter. You can use a filter in your capture tool, such as Wireshark, to see only wireless packets. If the UDP port 37008 isn't open, an ICMP packet with the error 'destination port unreachable' is generated for every packet sent by the access point. The access point encapsulates the wireless packets with TZSP and sends the archive to the configured server (running Wireshark) on UDP port 37008. The access point uses TaZmen Sniffer Protocol (TZSP) as an encapsulation protocol that runs over UDP. Packets intended for the access point and broadcasts are captured. Packet capture for AP and APX series access points Access pointsĪll packets received by the access point in the channel are captured. You must log into the access point UI to use the WLAN packet capture on AP6 series access points. It can only capture received (rx) packets.ĪP6 series access points capture received packets on the wired LAN ports. The access point can't capture its own transmitted packets. If you've configured Autochannel, the access points will capture packets on the channel picked by Autochannel. Go to Wireless > Diagnostics > Packet Capture and set up packet capture for your access points.įor more information on diagnosing and troubleshooting issues, see Frequently asked questions.Īn AP or APX series access point acts as a distributed sniffer and captures packets on the configured channel and configured channel width from remote access points. You can capture wireless packets from remote access points to diagnose and troubleshoot network issues. Your browser doesn’t support copying the link to the clipboard.
