Python netmiko 管理 ne

netmiko是python中可用于network device 备份的库，目前支持的设备如下:
As of June 2015, Netmiko has support for the following platforms:
Cisco IOS
Cisco IOS-XE
Cisco ASA
Cisco NX-OS
Cisco IOS-XR
Cisco WLC (limited testing)
Arista EOS
HP ProCurve
HP Comware (limited testing)
Juniper Junos
Brocade VDX (limited testing)
F5 LTM (experimental)
Huawei (limited testing)

from netmiko import ConnectHandler

cisco = {
    'device_type':'cisco_ios',
    'ip':'192.168.60.222',
    'username':'admin',
    'password': 'password',
    'secret':'google',   #enable password
}

connect=ConnectHandler(**cisco)     #对于两个*号，我的理解是：ConnectHandler()函数需要在cisco字典里面找"两"个东西,key和对应的value，所以用两个*星号

connect.enable()   #相当于进入特权模式
output_1 = connect.send_command('show run')
print("show run 的输出如下:\n"+output_1)
print("----------------------")

out_put_2 = connect.send_config_set('ip route 0.0.0.0 0.0.0.0 192.168.60.129')  #相当于输入特权模式 + 输入配置命令
print("配置默认路由后的输出:\n\n"+out_put_2+"\n\n")          #输出配置过程

show_route = connect.send_command('show ip route') #send_command('cli')命令执行的结果只能在本级，不能exit或者 enable、configure terminal
print("查看路由条目:\n"+show_route)

上述文件的输出如下（因篇幅问题,有部分会有删除）:

1、show run 的输出如下:
Building configuration...

Current configuration : 874 bytes
!
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec

 logging synchronous
line aux 0
 exec-timeout 0 0
 privilege level 15
 logging synchronous
line vty 0 4
 login local
!
!
end

----------------------

2、配置默认路由后的输出:

config term
Enter configuration commands, one per line.  End with CNTL/Z.
R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.60.129
R1(config)#end
R1#

3、查看路由条目:
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is 192.168.60.129 to network 0.0.0.0

C    192.168.60.0/24 is directly connected, FastEthernet0/0
S*   0.0.0.0/0 [1/0] via 192.168.60.129
