# enic.4

`enic` — VIC 以太网 NIC 驱动

## 名称

`enic`

## 概要

`若要将此驱动编译进内核，请在内核配置文件中加入以下行：`

> device iflib device enic

`若要在运行时以模块形式加载此驱动，请以 root 身份运行以下命令：`

```sh
kldload if_enic
```

`若要在引导时以模块形式加载此驱动，请在 loader.conf(5) 中加入以下行：`

```sh
if_enic_load="YES"
```

## 描述

`enic` 驱动为 Cisco 虚拟接口卡（Virtual Interface Card）提供支持。支持仅限于基本网络连接。媒体由 NIC 自身控制，因为可能向 PCI 总线暴露多个虚拟 PCI NIC 设备。

## 硬件

`enic` 驱动应支持所有已知的 Cisco VIC 卡。

## 配置

`enic` 网络接口使用 [ifconfig(8)](/man/man8/ifconfig.8.md) 和位于 `dev.enic.<N>` 的 [sysctl(8)](/man/man8/sysctl.8.md) 树进行配置。所有可配置条目同时也是可调参数，可直接放入 loader.conf(5) 以实现持久配置。

## 参见

[ifconfig(8)](/man/man8/ifconfig.8.md)

## 历史

`enic` 设备驱动首次出现于 FreeBSD 14.0。

## 作者

`enic` 驱动由 Cisco UCS 团队基于 DPDK 驱动编写。

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 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/man4/enic.4.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.
