pve_bridge_list

PVE 网桥接口状态列表美化工具

一键脚本

bash <(curl -sL gitee.com/meimolihan/linux-command_sh/raw/master/pve_bridge_list.sh)

效果预览

补充说明

该脚本用于查看 Linux 网桥（Bridge）状态及成员接口信息，基于 brctl、ip 和 /sys/class/net 实现，适合 PVE 节点上管理虚拟网桥的场景。

功能特点

• 网桥总览：展示所有网桥的名称、STP 状态、接口数、运行状态和 IP 地址
• 成员清单：详细列出每个网桥的成员接口及其 MAC 地址和类型
• 接口类型图标：🔗 网桥 / 🌐 物理网卡 / 🖥️ 虚拟机接口 / 🔥 防火墙接口 / 📡 VLAN
• 状态颜色标识：运行中（绿色）/ 已关闭（红色）
• 双模式查看：默认详细模式，-s 简化模式
• 统计信息：显示网桥数量和接口总数

输出说明

详细模式输出包含两部分：

参数示例

# 详细模式（默认）
bash pve_bridge_list.sh

# 简化模式
bash pve_bridge_list.sh -s

# 查看帮助
bash pve_bridge_list.sh -h

注意事项

• 需要 root 权限执行
• 依赖 bridge-utils（brctl 命令），未安装时会提示安装
• 适用于任何 Linux 系统，不限于 PVE，但 PVE 虚拟机环境接口（tap/veth）会特殊标识
