网络设备简单运维python加powershell（二）

改进

1、以前的代码比较适合交换机少的情况，一个交换机写一个代码，现在有70多台交换机，把交换机的信息导入sql数据库，然后用一段代码写完。（数据库真的很好用，导入修改都很方便，以后新增交换机，修改数据库就可以了）
2、生成的excel文档，行数太多，根据楼层，分层多个页，每页就不会有很多行。

代码

抓取交换机信息代码，改进。

import pexpect
import sys
import datetime
import os
import pymssql
today=datetime.date.today().strftime('%Y%m%d')
path = "/root/F5/"+today
os.mkdir(path,777)
passwd='xxx'
def Switch(S,I,N):#循环找到数据库每行里面对应的数据，交换机的名字、IP等。
    try:#遇到错误信息，直接掠过，防止因一个交换机信息有误，导致程序不能继续进行。
        name1="---- More ----"
        child=pexpect.spawn('telnet %s'%I)#循环telnetIP地址
        fout=open('/root/F5/'+today+'/'+'%s-%s.txt'%(S,I),'wb+')
        child.logfile = fout
        child.expect('Username:')
        child.sendline("admin")
        child.expect('(?i)ssword:')
        child.sendline("%s"%passwd)
        child.expect('<%s>'%N)
        child.sendline("dis mac-address")
        for i in range(10):
          index = child.expect([name1,'<%s>'%N])
          if ( index == 0 ):
            child.send(" ")
          else:
            child.sendline("quit")  
            break#不能用sys.exit()
    except:
         pass

host = 'x.x.x.x'
user = 'sa'
pwd = 'xxxxxx'
db = 'MAC'
conn = pymssql.connect(host=host,user=user,password=pwd,database=db,timeout=1,login_timeout=1,charset="utf8")
cur = conn.cursor()
sqls ="select * from [dbo].[F5Switch]"
cur.execute(sqls)
listall = cur.fetchall()
for line in listall:
    Switch(line[0],line[1],line[3])#循环输出sql数据库里面每一行的内容
conn.commit()
conn.close()

代码

抓取两个表中MAC地址一样的信息，并串接成一个表，并做成excel。改进：增加第一行颜色，更改行宽，分成多个表格。
