# 06_标准SOP与工具脚本
|
||||
|
||||
## 定位
|
||||
沉淀常用排障命令组合、自动化脚本和标准化操作流程（SOP），解决"具体敲什么命令"的问题。这是最贴近实战的操作手册。
|
||||
|
||||
## 内容要求
|
||||
- **命令速查卡**：将复杂排障流程浓缩为3-5步关键命令
|
||||
- **自动化脚本**：Python/Shell脚本，一键采集诊断信息
|
||||
- **抓包与解码规范**：协议报文的捕获方法和关键字段解析
|
||||
- **检查清单（Checklist）**：重大变更或故障处理的标准步骤
|
||||
|
||||
## 目录结构
|
||||
```
|
||||
06_标准SOP与工具脚本/
|
||||
├── MPLS标签排障命令速查.md
|
||||
├── BGP跨域故障排查SOP.md
|
||||
├── OSPF邻居异常快速诊断.md
|
||||
├── 抓包与解码规范.md
|
||||
└── 自动化采集脚本/
|
||||
├── collect_bgp_info.py
|
||||
└── check_mpls_labels.sh
|
||||
```
|
||||
|
||||
## RAG作用
|
||||
当用户说"帮我执行BGP排障"或"运行MPLS标签检查"时，AI直接调用这里的命令组合或脚本。
|
||||
|
||||
## 与01_协议排障逻辑树的区别
|
||||
- 01文件夹讲"排查思路"（If...Then...决策树）
|
||||
- 本文件夹讲"操作动作"（具体执行哪些show/debug命令）
|
||||
|
||||
## 最佳实践
|
||||
- 每个SOP不超过一页A4纸，便于打印携带
|
||||
- 命令附带"期望输出"和"异常判定标准"
|
||||
- 脚本具备自解释能力（含帮助信息和示例）

# 命令探索方法论：通过 `?` 在线帮助发现真实命令
|
||||
|
||||
## 为什么需要命令探索？
|
||||
|
||||
在实际网络运维中，我们经常遇到以下问题：
|
||||
- **文档过时**：厂商设备版本升级后命令语法变化
|
||||
- **记忆模糊**：记不清完整命令路径和参数格式
|
||||
- **设备差异**：不同厂商（ZTE/Huawei/Cisco）命令体系不同
|
||||
- **上下文依赖**：某些命令只在特定模式下可用
|
||||
|
||||
**解决方案**：使用设备内置的 `?` 在线帮助系统，像"剥洋葱"一样逐层探索。
|

|
||||
|
||||
## 核心原则：从宽到窄，逐步细化
|
||||
|
||||
### 探索路径示例：以BGP VPNv4路由查询为例
|
||||
|
||||
#### 第一步：确定顶层命令
|
||||
```bash
|
||||
MER1#show ?
|
||||
```
|
||||
输出会列出所有 `show` 开头的命令类别：
|
||||
```
|
||||
bgp Show BGP information
|
||||
ip Show IP information
|
||||
mpls Show MPLS information
|
||||
isis Show IS-IS routing information
|
||||
...
|
||||
```
|
||||
|
||||
#### 第二步：进入子命令层级
|
||||
```bash
|
||||
MER1#show bgp ?
|
||||
```
|
||||
输出显示BGP相关的地址族：
|
||||
```
|
||||
ipv4 IPv4 address family
|
||||
vpnv4 VPNv4 address family
|
||||
evpn Display information about all EVPN NLRIs
|
||||
...
|
||||
```
|
||||
|
||||
#### 第三步：继续深入具体类型
|
||||
```bash
|
||||
MER1#show bgp vpnv4 ?
|
||||
```
|
||||
输出显示VPNv4的单播/组播分类：
|
||||
```
|
||||
unicast Display information about all VPNv4 NLRIs
|
||||
multicast Display information about all VPNv4 multicast NLRIs
|
||||
flowspec Flow specification address family modifier
|
||||
...
|
||||
```
|
||||
|
||||
#### 第四步：查看可用的操作符和参数
|
||||
```bash
|
||||
MER1#show bgp vpnv4 unicast ?
|
||||
```
|
||||
**关键输出**（这是最有价值的一步）：
|
||||
```
|
||||
as Autonomous system
|
||||
community Show route community information
|
||||
dampened-paths Show paths suppressed due to dampening
|
||||
detail Display detailed information about an ip prefix
|
||||

|
||||
in Show route information received from all neighbors
|
||||
labels Display BGP labels for prefixes
|
||||
neighbor Detailed information on TCP and BGP neighbor connections
|
||||
network Show route information
|
||||
rd Specify route distinguisher
|
||||
rd-by-vrf Specify route distinguisher by VRF name
|
||||
vrf Display information for a VPN Routing/Forwarding instance
|
||||
| Output modifiers (管道符，用于过滤)
|
||||
> Redirect the output to a file (重定向到文件)
|
||||
<cr> Carriage return (直接回车执行)
|
||||
```
|
||||
|
||||
#### 第五步：选择VRF相关选项继续探索
|
||||
```bash
|
||||
MER1#show bgp vpnv4 unicast vrf ?
|
||||
```
|
||||
输出显示可用的VRF实例名称：
|
||||
```
|
||||
5G_MEC VPN Routing/Forwarding instance name
|
||||
IP_RAN VPN Routing/Forwarding instance name
|
||||
test VPN Routing/Forwarding instance name
|
||||
WORD VPN Routing/Forwarding instance name (任意字符串)
|
||||
```
|
||||
|
||||
#### 第六步：查看VRF下的具体操作
|
||||
```bash
|
||||
MER1#show bgp vpnv4 unicast vrf test ?
|
||||
```
|
||||
最终得到精确命令：
|
||||
```
|
||||
detail Show route detail information
|
||||
export-unicast Export VRF routes to unicast routing table
|
||||
import-unicast Import unicast routes to VRF routing table

|
||||
```
|
||||
|
||||
#### 第七步：执行最终命令
|
||||
```bash
|
||||
MER1#show bgp vpnv4 unicast vrf test route
|
||||
```
|
||||
输出完整的BGP VPNv4路由表：
|
||||

|
||||
|
||||
## 高级技巧：组合使用 `?` 和其他工具
|
||||
|
||||
### 技巧1：利用 `<cr>` 提示判断命令完整性
|
||||
|
||||
当 `?` 输出中包含 `<cr>` 时，表示当前命令已经完整，可以直接执行：
|
||||
```bash
|
||||
MER1#show mpls ldp neighbor brief instance 1 ?
|
||||
<cr> ← 看到这个，就知道可以直接回车执行了
|
||||
```
|
||||
|
||||
### 技巧2：使用管道符 `|` 过滤大量输出
|
||||
|
||||
当某个命令输出太多时，用 `?` 查看可用的过滤选项：
|
||||
```bash
|
||||
MER1#show bgp vpnv4 unicast vrf test route ?
|
||||
| Output modifiers
|
||||
|
||||
MER1#show bgp vpnv4 unicast vrf test route | ?
|
||||
begin Begin with the line that matches
|
||||
count Count the number of lines that match
|
||||
exclude Exclude lines that match
|
||||
include Include lines that match
|
||||
section Print only the section that matches
|
||||
|
||||
# 实际应用：只看包含特定前缀的路由
|
||||
MER1#show bgp vpnv4 unicast vrf test route | include 4.1.1
|
||||
```
|
||||
|
||||
### 技巧3：在配置模式下同样适用
|
||||
|
||||
`?` 不仅适用于特权模式（`#`），也适用于配置模式（`(config)#`）：
|
||||
```bash
|
||||
MER1#configure terminal
|
||||
MER1(config)#router bgp 100
|
||||
MER1(config-bgp-router)#neighbor ?
|
||||
A.B.C.D Neighbor IPv4 address
|
||||
X:X::X:X Neighbor IPv6 address
|
||||
peer-group Name of peer group
|
||||
|
||||
MER1(config-bgp-router)#neighbor 10.26.63.152 ?
|
||||
activate Enable the neighbor
|
||||
advertisement-interval Set minimum interval between sending routing updates
|
||||
allowas-in Allow AS in path
|
||||
...
|
||||
next-hop-self Disable the next hop calculation for this neighbor ← 关键配置！
|
||||
...
|
||||
```
|
||||
|
||||
### 技巧4：识别命令缩写规则
|
||||
|
||||
通过 `?` 可以发现命令的简写形式：
|
||||
```bash
|
||||
MER1#sh ?
|
||||
show Show running system information
|
||||
|
||||
MER1#show mpls forw ?
|
||||
forwarding-table Show MPLS forwarding-table information ← forw是forwarding的合法缩写
|
||||
```
|
||||
|
||||
**规律**：只要输入的字母能唯一标识一个命令，就可以缩写。例如：
|
||||
- `show` → `sh`
|
||||
- `forwarding-table` → `forw`
|
||||
- `configuration` → `conf`
|
||||
|
||||

|
||||
|
||||
## 常见命令树结构对比
|
||||
|
||||
### ZTE vs Huawei vs Cisco
|
||||
|
||||
| 功能 | ZTE (ZXROS) | Huawei (VRP) | Cisco (IOS) |
|
||||
|------|-------------|--------------|-------------|
|
||||
| 查看BGP VPNv4路由 | `show bgp vpnv4 unicast vrf <name> route` | `display bgp vpnv4 routing-table vpn-instance <name>` | `show bgp vpnv4 unicast vrf <name>` |
|
||||
| 查看MPLS转发表 | `show mpls forwarding-table` | `display mpls lsp` | `show mpls forwarding-table` |
|
||||
| 查看LDP邻居 | `show mpls ldp neighbor brief instance 1` | `display mpls ldp session` | `show mpls ldp neighbor` |
|
||||
| Ping VRF内地址 | `ping vrf <name> <ip>` | `ping -vpn-instance <name> <ip>` | `ping vrf <name> <ip>` |
|
||||
|
||||
**结论**：虽然命令相似，但细节有差异。**必须针对每种设备单独探索**。
|
||||
|
||||

|
||||
|
||||
## 错误处理与注意事项
|
||||
|
||||
### 注意1：命令前缀限制
|
||||
|
||||
某些平台可能限制特定命令的使用：
|
||||
```bash
|
||||
# 如果收到 "command_not_allowed_prefix" 错误
|
||||
MER1#trace vrf test 4.1.1.1
|
||||
%Error: command_not_allowed_prefix
|
||||
```
|
||||
**原因**：`trace` 命令可能被netx等平台限制。此时应尝试：
|
||||
- 改用完整路径 `traceroute`
|
||||
- 检查权限级别
|
||||
- 使用替代命令（如通过ping逐跳测试）
|
||||
|
||||
### 注意2：区分"不完整命令"和"无匹配"
|
||||
|
||||
```bash
|
||||
# 不完整命令（Incomplete command）- 说明方向对，继续用？探索
|
||||
MER1#show bgp vpnv4 unicast vrf test
|
||||
%Error 140305: Incomplete command.
|
||||
|
||||
# 无匹配（Unrecognized command）- 说明走错路了，退回上一层
|
||||
MER1#show bgp vpnv4 unicast vrf test xyz
|
||||
%Error: Unrecognized command.
|
||||
```
|
||||
|
||||
### 注意3：空格敏感性
|
||||
|
||||
```bash
|
||||
# 正确：每个层级之间有空格
|
||||
MER1#show mpls ldp neighbor brief instance 1
|
||||
|
||||
# 错误：连在一起会当成一个单词
|
||||
MER1#show mplsldpneighborbriefinstance1
|
||||
%Error: Unrecognized command.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 练习：自主探索以下命令
|
||||
|
||||
请用 `?` 方法探索下列命令的完整语法（答案不唯一）：
|
||||
|
||||
1. 查看ISIS邻接关系
|
||||
2. 查看OSPF邻居详细信息
|
||||
3. 查看VRF IP_RAN的路由表
|
||||
4. 查看MPLS标签绑定信息
|
||||
5. 查看BGP从邻居10.26.63.152收到的路由
|
||||
|
||||
**参考答案**（实际以设备为准）：
|
||||
```bash
|
||||
# 1. ISIS邻接
|
||||
MER1#show isis adjacency
|
||||
|
||||
# 2. OSPF邻居详细
|
||||
MER1#show ip ospf neighbor detail
|
||||
|
||||
# 3. VRF IP_RAN路由
|
||||
MER1#show ip forwarding route vrf IP_RAN
|
||||
|
||||
# 4. MPLS标签绑定
|
||||
MER1#show mpls ldp bindings
|
||||
|
||||
# 5. BGP从邻居收到的路由
|
||||
MER1#show bgp vpnv4 unicast vrf test received 10.26.63.152
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 总结：命令探索五步法
|
||||
|
||||
1. **定方向**：从最顶层开始（`show ?`, `ping ?`, `configure ?`）
|
||||
2. **剥洋葱**：每层用 `?` 查看下一级选项，选择最相关的分支
|
||||
3. **看提示**：注意 `<cr>`、`WORD`、`A.B.C.D` 等元提示
|
||||
4. **试执行**：看到 `<cr>` 就执行，观察输出验证猜测
|
||||
5. **记笔记**：把成功的命令路径记录下来（就像本文档做的）
|
||||
|
||||
**终极心法**：不要怕敲错，`?` 永远不会嘲笑你。每个网络专家都是从不停地敲 `?` 开始的。

## 九、命令语法说明
|
||||
|
||||
### 9.1 重要注意事项
|
||||
1. **LDP命令必须指定instance**：`show mpls ldp neighbor brief instance <id>` ✅
|
||||
- `show mpls ldp neighbor brief` ❌ Incomplete command
|
||||
|
||||
2. **BGP VPNv4路由查询**：`show bgp vpnv4 unicast vrf <vrf-name> route` ✅
|
||||
- `show bgp vpnv4 unicast rd-by-vrf <vrf-name>` ❌ Incomplete command
|
||||
- `show bgp ipv4 unicast route` ❌ Ambiguous command
|
||||
|
||||
3. **VRF路由查询**：`show ip forwarding route vrf <vrf-name>` ✅
|
||||
- `show ip route vrf <vrf-name>` ❌ Invalid input
|
||||
- `show ipv4 route vrf <vrf-name>` ❌ Invalid input
|
||||
|
||||
### 9.2 特殊字符限制
|
||||
netx平台限制了管道符等特殊字符的使用，建议分步执行命令。
