# Airodump 过滤模式
按信道、ESSID 或 BSSID 聚焦授权捕获。
`airodump-ng` 可以一次显示多个接入点。过滤捕获内容，以聚焦于范围内的资产。
{% hint style="warning" %}
仅捕获已获批准的设备。过滤器不能替代评估授权。
{% endhint %}
### 选择过滤条件
当你知道接入点频率时，使用信道。使用 ESSID 按名称跟踪网络。使用 BSSID 识别特定无线电。
### 按信道过滤
```bash
airodump-ng -c 1 wlan0mon
```
该 `-c` 该值必须与侦察期间观察到的信道匹配。
### 按 ESSID 过滤
按网络广播的名称过滤：
```bash
airodump-ng --essid WIFI wlan0mon
```
### 按 BSSID 过滤
按接入点 MAC 地址过滤：
```bash
airodump-ng --bssid BC:0F:9A:66:1A:8E wlan0mon
```
当多个网络使用相同名称时，BSSID 可消除歧义。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/zh/hacking-wifi/wpa-wpa2-psk-network-attacks/reconnaissance-and-capture/airodump-filter-modes.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
