NuMoOne: 2009

前段时间做care的同事提出，在平时维护时发现以前安装调测的交换机上有很多不规范或错误的配置。这大概都是由于验收时无法去很仔细地看配置造成的。由此想到有没有一个工具可以提取交换机的配置，生成一个易读的报告？在网上用Cisco Configuration parser做keyword搜了一下，只找到一个用perl写的只能分析出交换机接口的脚本，用处不大。于是自己用Python写了一个sw_confparser，目前基本上能达到当初的目的，就差完善相关的配置模板了。

脚本上传到google code的net-mon-man项目里了，下载在这里

sw_confparser.py使用说明
sw_confparser可以将交换机的配置提取出来，导入到excel或数据库里去。
sw_confparser需要两个文件：

cisco交换机的show running config命令的输出文本
以yaml格式编写的交换机配置模板。例子如下：

#more c6509.yml

Hostname:
configname: [Hostname]
pattern: hostname (.*)

hardware:
configname: [Name,description,PID,VID,SN]
pattern: |
NAME: "(.*)", DESCR: "(.*)"
PID: (.*), VID: (.*), SN: (.*)

Memory:
configname: [Free memory,Used memory]
pattern: cisco WS-C6509-E \(R7000\) processor \(revision 1.2\) with (.*)/(.*) bytes of memory

IOS Version:
configname: [IOS version]
pattern: IOS \(tm\) s3223_rp Software \(s3223_rp-IPBASEK9-M\), Version (.*), RELEASE SOFTWARE \(fc3\)

ROM version:
configname: [Rom version]
pattern: "ROM: System Bootstrap, Version (.*), RELEASE SOFTWARE"

System Image:
configname: [Image file]
pattern: System image file is "(.*)"

System Register:
configname: [Register]
pattern: Configuration register is (.*)

Timezone:
configname: [Timezone]
pattern: clock timezone (.*)

STP Mode:
configname: [STP Mode]
pattern: spanning-tree mode (.*)

Log Server:
configname: [Log Server]
pattern: logging (\d+.\d+.\d+.\d+)

Snmp Agent:
configname: [RO string, RW string, trap-source]
pattern: |
snmp-server community (\w+) RO
snmp-server community (\w+) RW
snmp-server trap-source (\w+)
SNMP Trap Server:
configname: [server address,server string]
pattern: snmp-server host (\d+.\d+.\d+.\d+) (\w+)

NTP server:
configname: [server]
pattern: ntp server (\d+.\d+.\d+.\d+)

Static Route:
configname: [dest, netmark, gateway,description]
pattern: |
ip route (\d+.\d+.\d+.\d+) (\d+.\d+.\d+.\d+) (\d+.\d+.\d+.\d+) name (.*)

将以上两个文件作为脚本的参数执行，就可以啦。如不加任何参数则会打印出帮助信息。

输出例子：

python sw_confparser.py log/dgswtest1.log c6509.yml -c
