Use Packet Capture

The Packet Capture tool is available for ExtremeWireless WiNG access points (APs) at the site level or at the individual device level. The tool captures information about network traffic to assist with forensics (such as detect misuse of the network by internal or external users) and help troubleshoot network problems (such as utilization of network resources).

To capture packet information:

  1. From the menu on the left, do one of the following:
    • Select Tools > Sites. Select a site from the list that displays. You will be able to capture information for all APs or for a single AP at the site.
    • Select Tools > Access Points.
  2. Select the Packet Capture tab.
