In the current version, only IEEE802.11 data frames with QoS data are processed to display statistics about the access points and participants and their quality. All other IEEE802.11 frame are skipped. | In the current version, only IEEE802.11 data frames with QoS data are processed to display statistics about the access points and participants and their quality.

Beacon frames are also analyzed and additional information like SSID name, access point name, channel utilization are shown too (Firmware >= 3.4). | |||

=== Traffic processing === | |||
There are currently two kinds of 802.11 traffic that can be analyzed: | |||
# PEEKREMOTE packets This kind of traffic is generated by access points and is send via UDP to a specified IP address and port. To analyze this traffic, the endpoint mode has to be enabled on an interface which receives this traffic. In the endpoint mode configuration, an IP address and port can be configured for which the Allegro Network Multimeter accepts packets. PEEKREMOTE packets usually do not contain complete IP packets, only 802.11 statistics that are evaluated by the Allegro Network Multimeter. | |||
# CAPWAP encapsulated packets In contrast to PEEKREMOTE, CAPWAP packets encapsulate complete IP packets which itself contain 802.11 information. Therefore, the endpoint mode must be configured for a specific IP and port and the tunnel view mode must be enabled too to let the Allegro Network Multimeter look inside the encapsulated packets. | |||
