LWAPP Traffic Across the WAN

LWAPP Traffic Classification

LWAPP APs can be generally separated into the following two types:

•

LWAPP control traffic—Identified by UDP port 12223

•

LWAPP 802.11 traffic—Identified by UPD port 12222

LWAPP Control Traffic

LWAPP control traffic can be generally divided into the following two additional types:

•

Initialization traffic—Generated when an LWAPP AP is booted and joins an LWAPP system. For
example, the traffic generated by controller discovery, AP configuration, and AP firmware updates.

Note

LWAPP image packets from the controller are marked best-effort, but their acknowledgement is
marked CS6. Note that there is no windowing of the protocol, and each additional packet is sent
only after an acknowledgement. This type of handshaking minimizes the impact of downloading
files over a WAN

•

Background traffic—Generated by an LWAPP AP when it is an operating member of a WLAN
network. For example, LWAPP heartbeat, RRM, rogue AP measurements. Background LWAPP
control traffic is marked CS6.
