华为路由器常用的Python脚本(网工自动化脚本编写)

昨天给大家介绍了10个华为交换机的Python脚本：

• 华为交换机常用的Python脚本

大家反响不错，后期我会陆续出一下思科、H3C、锐捷等厂商的脚本，前期会分享简单的，单一的脚本，后面会分享复杂的脚本。

今天给大家分享20个常用的Python脚本，用于控制和管理华为路由器：

1、登录和退出路由器：

import telnetlib

HOST = "192.168.1.1"
user = "admin"
password = "admin"

tn = telnetlib.Telnet(HOST)

tn.read_until(b"Username: ")
tn.write(user.encode('ascii') + b"\n")

tn.read_until(b"Password: ")
tn.write(password.encode('ascii') + b"\n")

tn.write(b"quit\n")

2、获取路由器的系统信息：

import paramiko

host = "192.168.1.1"
port = 22
username = "admin"
password = "admin"

client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname=host, port=port, username=username, password=password)

stdin, stdout, stderr = client.exec_command("display version")

for line in stdout:
    print(line.strip())

client.close()

3、配置路由器端口：

import telnetlib

HOST = "192.168.1.1"
user = "admin"
password = "admin"

tn = telnetlib.Telnet(HOST)

tn.read_until(b"Username: ")
tn.write(user.encode('ascii') + b"\n")

tn.read_until(b"Password: ")
tn.write(password.encode('ascii') + b"\n")

tn.write(b"system-view\n")
tn.write(b"interface GigabitEthernet0/0/1\n")
tn.write(b"ip address 192.168.2.1 255.255.255.0\n")
tn.write(b"quit\n")

tn.write(b"quit\n")

4、查看路由器端口状态：

import paramiko

host = "192.168.1.1"
port = 22
username = "admin"
password = "admin"

client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname=host, port=port, username=username, password=password)

stdin, stdout, stderr = client.exec_command("display interface GigabitEthernet0/0/1")

for line in stdout:
    print(line.strip())

client.close()

5、配置路由器的SNMP：

import telnetlib

HOST = "192.168.1.1"
user = "admin"
password = "admin"

tn = telnetlib.Telnet(HOST)

tn.read_until(b"Username: ")
tn.write(user.encode('ascii') + b"\n")

tn.read_until(b"Password: ")
tn.write(password.encode('ascii') + b"\n")

tn.write(b"system-view\n")
tn.write(b"snmp-agent sys-info version all\n")
tn.write(b"snmp-agent community read public\n")
tn.write(b"snmp-agent target-host trap address udp-domain 192.168.2.2 params securityname public\n")
tn.write(b"quit\n")

tn.write(b"quit\n")

6、配置路由器的ACL：

import telnetlib

HOST = "192.168.1.1"
user = "admin"
password = "admin"

tn = telnetlib.Telnet(HOST)

tn.read_until(b"Username: ")
tn.write(user.encode('ascii') + b"\n")

tn.read_until(b"Password: ")
tn.write(password.encode('ascii') + b"\n")

tn.write(b"system-view\n")

tn.write(b"acl number 2000\n")
tn.write(b"rule 5 permit source 192.168.2.0 0.0.0.255\n")
tn.write(b"quit\n")

tn.write(b"interface GigabitEthernet0/0/1\n")
tn.write(b"ip address 192.168.2.1 255.255.255.0\n")
tn.write(b"traffic-filter inbound acl 2000\n")
tn.write(b"quit\n")

tn.write(b"quit\n")

7、配置路由器的静态路由：

import telnetlib

HOST = "192.168.1.1"
user = "admin"
password = "admin"

tn = telnetlib.Telnet(HOST)

tn.read_until(b"Username: ")
tn.write(user.encode('ascii') + b"\n")

tn.read_until(b"Password: ")
tn.write(password.encode('ascii') + b"\n")

tn.write(b"system-view\n")
tn.write(b"ip route-static 192.168.3.0 255.255.255.0 192.168.2.2\n")
tn.write(b"quit\n")

tn.write(b"quit\n")

8、配置路由器的NAT：

import telnetlib

HOST = "192.168.1.1"
user = "admin"
password = "admin"

tn = telnetlib.Telnet(HOST)

tn.read_until(b"Username: ")
tn.write(user.encode('ascii') + b"\n")

tn.read_until(b"Password: ")
tn.write(password.encode('ascii') + b"\n")

tn.write(b"system-view\n")
tn.write(b"interface GigabitEthernet0/0/0\n")
tn.write(b"nat enable\n")
tn.write(b"quit\n")

tn.write(b"nat address-group 1 192.168.2.0 0.0.0.255\n")
tn.write(b"nat server protocol tcp global 202.96.209.5 inside 192.168.2.100 80\n")
tn.write(b"quit\n")

tn.write(b"quit\n")

tn.write(user.encode('ascii') + b"\n")

tn.read_until(b"Password: ")
tn.write(password.encode('ascii') + b"\n")

tn.write(b"system-view\n")
tn.write(b"dhcp enable\n")
tn.write(b"interface GigabitEthernet0/0/1\n")
tn.write(b"dhcp server excluded-ip-address 192.168.2.1\n")
tn.write(b"dhcp server pool 1\n")
tn.write(b"network 192.168.2.0 mask 255.255.255.0\n")
tn.write(b"gateway-list 192.168.2.1\n")

这些Python脚本可以帮助你快速查看华为路由器的各种信息，也可以作为开发的基础，进行更多高级的操作和自动化任务。
