# Modos de Filtro do Airodump

Direcione uma captura autorizada por canal, ESSID ou BSSID.

`airodump-ng` pode exibir vários pontos de acesso de uma vez. Filtre a captura para focar em um ativo dentro do escopo.

{% hint style="warning" %}
Capture equipamentos aprovados. Um filtro não substitui a autorização da avaliação.
{% endhint %}

### Escolha um filtro

Use um canal quando você souber a frequência do ponto de acesso. Use um ESSID para acompanhar uma rede pelo nome. Use um BSSID para identificar um rádio específico.

### Filtrar por canal

```bash
airodump-ng -c 1 wlan0mon
```

O `-c` o valor deve corresponder ao canal observado durante o reconhecimento.

### Filtrar por ESSID

Filtrar pelo nome divulgado da rede:

```bash
airodump-ng --essid WIFI wlan0mon
```

### Filtrar por BSSID

Filtrar pelo endereço MAC do ponto de acesso:

```bash
airodump-ng --bssid BC:0F:9A:66:1A:8E wlan0mon
```

O BSSID elimina a ambiguidade quando várias redes compartilham o mesmo nome.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/pt-br/hacking-wifi/wpa-wpa2-psk-network-attacks/reconnaissance-and-capture/airodump-filter-modes.md?ask=<question>&goal=<user_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.
