![]() By default, all the access points are displayed. You can also filter access points based on the sites. 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 display filter in your capture tool such as Wireshark to see only wireless packets. If the UDP port 37008 is not open, an Internet Control Message Protocol (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 it 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 User Datagram Protocol (UDP). Packets intended for the access point and broadcasts are captured. Packet capture across all access points Access pointsĪll packets received by the access point in the channel are captured. It can only capture received (rx) packets. The access point can't capture its own transmitted packets. If you have configured Autochannel, the access points will capture packets on the channel picked by Autochannel. The access point acts as a distributed sniffer, and captures packets on the configured channel and configured channel width from remote access points. 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. ![]() Capture wireless packets from remote access points to diagnose and troubleshoot network issues. ![]()
