# ieee80211\_ddb(9)

802\.11 ddb support

## NAME

**ieee80211\_ddb** – 802.11 ddb support

## SYNOPSIS

**options** **DDB**

**show** **vap** **\[addr\]** **show** **all** **vaps** **show** **com** **\[addr\]** **show** **sta** **\[addr\]** **show** **statab** **\[addr\]** **show** **mesh** **\[addr\]**

## DESCRIPTION

The **net80211** layer includes [ddb(4)](/ddb/4.md) 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.
