ieee80211_ddb(9) 802.11 ddb support


options DDB show vap [addr] show all vaps show com [addr] show sta [addr] show statab [addr] show mesh [addr]


The net80211 layer includes ddb(4) support for displaying important data structures. This is especially important because wireless applications are often built for embedded environments where cross-machine or post-mortem debugging facilities like kgdb(1) are infeasible.

The most commonly used command is

show all vaps/a

which dumps the contents of all Vt ieee80211vap , Vt ieee80211com , and Vt ieee80211_node data structures in the system.
