interface-config

interface-config is a skill for Claude Code, Codex from nanxiaoyao/network-huawei-skills. It costs 124 tokens per session (2,831 once invoked), scanned A, original, MIT.

A guide for configuring and troubleshooting physical interfaces and link aggregation on Huawei CloudEngine and S-series switches. Link aggregation combines multiple network links for more bandwidth and backup capacity.

In plain words
What is it for?
Setting interface speed, duplex, MTU, jumbo frames, flow control, and PoE; diagnosing errors; and configuring manual or LACP Eth-Trunks and cross-device aggregation.
Why use it?
It brings common interface, cable, error, PoE, and LACP troubleshooting into one reference.

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

interface-config 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 10d 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.

华为交换机接口与链路聚合配置技能 (interface-config)

适用平台 S 系列 V200R011C10+ | CE 系列 V200R022C00+ 文档来源 华为产品文档 dc_cfg_int_* / dc_cfg_eth-trunk_*

接口是所有协议的物理底座 出问题先看接口 Eth-Trunk 链路聚合是接口的逻辑形态 提带宽+冗余

触发场景

  • 接口配置 IP / 描述 / 速率 / 双工
  • 接口物理 down 不通
  • 大量错包 CRC 错 入向丢包
  • 配 MTU / 巨帧 jumbo frame
  • PoE 供电
  • 配置 Eth-Trunk 链路聚合(手工 / LACP)
  • LACP 不协商 / 成员口不上线
  • 跨设备聚合(M-LAG 堆叠跨设备聚合)
  • Trunk 链路两端速率不匹配

物理接口配置

基础属性

interface GigabitEthernet 0/0/1
 description To-CoreSW
 speed 1000              # 速率 10/100/1000
 duplex full             # 双工
 negotiation disable     # 关闭自协商(双方都关或都开 否则速率不匹配)
 mtu 9216                # 巨帧(默认 1500)
 jumboframe enable 9216
 flow-control            # 流控
 undo shutdown

接口三层化

interface GigabitEthernet 0/0/1
 undo portswitch         # 转为三层口(仅部分款支持)
 ip address 10.1.1.1 24

PoE 供电(S 系列接入交换机)

interface GigabitEthernet 0/0/1
 poe enable
 poe power max 30000     # 30W 最大功率(mW)
 poe priority { critical | high | low }
display poe interface     # 查 PoE 状态
display poe power         # 查总功耗

错包诊断

display interface GigabitEthernet 0/0/1
# 看 Input/Output errors、CRC、Frames、Drops 等计数
clear counters interface GigabitEthernet 0/0/1

Eth-Trunk 链路聚合

两种模式

模式 适用 协商
手工 manual 简单 不要协商 无 LACP
LACP(lacp-static) 推荐 自动协商 故障检测 LACP 报文

配置 手工模式

interface Eth-Trunk 1
 mode manual load-balance       # 手工模式 默认就是
 quit

interface GigabitEthernet 0/0/1
 eth-trunk 1
 quit
interface GigabitEthernet 0/0/2
 eth-trunk 1
 quit

配置 LACP 模式(推荐)

interface Eth-Trunk 1
 mode lacp-static
 lacp preempt enable
 lacp preempt delay 30
 max active-linknumber 4
 min active-linknumber 1
 quit

interface GigabitEthernet 0/0/1
 eth-trunk 1
interface GigabitEthernet 0/0/2
 eth-trunk 1

LACP 系统优先级与接口优先级

# 系统优先级 决定谁是 Actor 哪边的接口优先级生效
lacp priority 100               # 系统级 默认 32768

# 接口优先级 决定哪些接口为活动接口
interface GigabitEthernet 0/0/1
 lacp priority 100              # 接口级

两端比较:系统优先级数值小的胜 然后比较 MAC 接口优先级数值小为活动

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.

Changes

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.

interface-config is a skill published in the GitHub repository nanxiaoyao/network-huawei-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 124 tokens to every session and 2,831 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.
