mirror

mirror is a skill for Claude Code, Codex from nanxiaoyao/network-huawei-skills. It costs 127 tokens per session (2,744 once invoked), scanned A, original, MIT.

A guide for configuring traffic mirroring on Huawei CloudEngine and S-series switches. Traffic mirroring copies network traffic to another port or device for inspection while the original traffic continues normally.

In plain words
What is it for?
Use it to set up local or remote mirroring, copy traffic selected by rules, connect analysis or security tools, and investigate issues such as broadcast storms or ARP problems.
Why use it?
It helps when you need to capture packets or inspect selected traffic without interrupting the live network.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mirror scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

华为交换机镜像配置技能 (mirror)

适用平台 S 系列 V200R011C10+ | CE 系列 V200R022C00+ 文档来源 华为产品文档 dc_cfg_mirror_*

镜像把流量复制一份送到观察口 用于流量分析 抓包 安全审计 不影响原业务

触发场景

  • 业务异常 要抓包定位
  • 安全审计 流量监听
  • 接 IDS/IPS/流量分析仪
  • 排查广播风暴 / ARP 异常
  • 验证 ACL 是否生效
  • 配置远程镜像 跨设备送流量

镜像类型对比

类型 复制源 复制到 适用
本地端口镜像 Local Port 接口入/出/双向 本机另一接口 单机抓包 最简单
远程端口镜像 RSPAN 接口流量 远端设备的接口(经 VLAN 传输) 跨设备抓包
本地流镜像 Local Flow 符合 ACL 的流量 本机另一接口 精确抓取某类流量
远程流镜像 符合 ACL 的流量 远端接口 跨设备精准抓
MQC 镜像 流分类匹配的流 本机/远端 灵活分类

基本概念

术语 解释
镜像源 mirror source 被复制流量的接口或流
观察口 observe-port 接收复制流量的接口(接抓包设备)
镜像方向 inbound 入 / outbound 出 / both 双向
镜像比例 全部 1:1 或按比例采样

配置三步走 本地端口镜像

1 配置观察口

system-view
observe-port 1 interface GigabitEthernet 0/0/24

观察口接抓包电脑或流量分析仪 不能再做其他业务

2 配置镜像源

interface GigabitEthernet 0/0/1
 port-mirroring to observe-port 1 inbound      # 入向
 port-mirroring to observe-port 1 outbound     # 出向
 port-mirroring to observe-port 1 both         # 双向

3 验证

display observe-port
display port-mirroring

远程镜像 RSPAN

拓扑

[源SW] → 业务VLAN透传镜像VLAN → [中间SW] → [目的SW with 观察口]

配置 源 SW

# 1 创建镜像 VLAN
vlan 100
 description Mirror-VLAN
 quit

# 2 观察口指向镜像 VLAN
observe-port 1 vlan 100

# 3 镜像源接口
interface GigabitEthernet 0/0/1
 port-mirroring to observe-port 1 inbound

# 4 上联口透传镜像 VLAN
interface GigabitEthernet 0/0/24
 port link-type trunk
 port trunk allow-pass vlan 100

配置 中间 SW

# 只需透传镜像 VLAN
interface GigabitEthernet 0/0/1
 port link-type trunk
 port trunk allow-pass vlan 100
interface GigabitEthernet 0/0/2
 port link-type trunk
 port trunk allow-pass vlan 100

配置 目的 SW

# 1 镜像 VLAN
vlan 100

# 2 抓包口加入镜像 VLAN
interface GigabitEthernet 0/0/24
 port link-type access
 port default vlan 100

抓包设备从该接口收到所有源 SW 的镜像流量

本地流镜像(按 ACL)

# 1 定义 ACL 圈定关心的流量
acl number 3000
 rule 5 permit tcp source 10.1.1.0 0.0.0.255 destination-port eq 80
 quit

# 2 创建流分类
traffic classifier c1
 if-match acl 3000
 quit

# 3 创建流行为 引用观察口
traffic behavior b1
 mirror to observe-port 1
 quit

# 4 流策略绑定
traffic policy p1
 classifier c1 behavior b1
 quit

# 5 接口下发
interface GigabitEthernet 0/0/1
 traffic-policy p1 inbound

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mirror is a skill published in the GitHub repository nanxiaoyao/network-huawei-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 127 tokens to every session and 2,744 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
