IEEE80211_DDB(9) FreeBSD Kernel Developer's Manual IEEE80211_DDB(9)

ieee80211_ddb — 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) (ports/devel/gdb) are infeasible.

The most commonly used command is

show all vaps/a

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

ddb(4), ieee80211(9)

August 4, 2009 FreeBSD 14.3-RELEASE
