# ieee80211\_ddb.9

`ieee80211_ddb` — 802.11 ddb 支持

## 名称

`ieee80211_ddb`

## 概要

> options DDB

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

## 描述

`net80211` 层包括 [ddb(4)](/man/man4/ddb.4.md) 支持以显示重要数据结构。这尤其重要，因为无线应用程序通常为嵌入式环境构建，在这些环境中，kgdb(1)（`ports/devel/gdb`）等跨机或事后调试设施不可行。

最常用的命令是

```sh
show all vaps/a
```

它转储系统中所有 `ieee80211vap`、`ieee80211com` 和 `ieee80211_node` 数据结构的内容。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man9/ieee80211_ddb.9.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
