- 10个华为华为交换机常用的Python脚本，网络工程师收藏！
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"quitn")
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-viewn")
tn.write(b"interface GigabitEthernet0/0/1n")
tn.write(b"ip address 192.168.2.1 255.255.255.0n")
tn.write(b"quitn")
tn.write(b"quitn")
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-viewn")
tn.write(b"snmp-agent sys-info version alln")
tn.write(b"snmp-agent community read publicn")
tn.write(b"snmp-agent target-host trap address udp-domain 192.168.2.2 params securityname publicn")
tn.write(b"quitn")
tn.write(b"quitn")
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-viewn")
tn.write(b"acl number 2000n")
tn.write(b"rule 5 permit source 192.168.2.0 0.0.0.255n")
tn.write(b"quitn")
tn.write(b"interface GigabitEthernet0/0/1n")
tn.write(b"ip address 192.168.2.1 255.255.255.0n")
tn.write(b"traffic-filter inbound acl 2000n")
tn.write(b"quitn")
tn.write(b"quitn")

tn.write(user.encode('ascii') + b"n")
tn.read_until(b"Password: ")
tn.write(password.encode('ascii') + b"n")
tn.write(b"system-viewn")
tn.write(b"ip route-static 192.168.3.0 255.255.255.0 192.168.2.2n")

tn.write(user.encode('ascii') + b"n")
tn.read_until(b"Password: ")
tn.write(password.encode('ascii') + b"n")
tn.write(b"system-viewn")
tn.write(b"interface GigabitEthernet0/0/0n")
tn.write(b"nat enablen")
tn.write(b"quitn")
tn.write(b"nat address-group 1 192.168.2.0 0.0.0.255n")
tn.write(b"nat server protocol tcp global 202.96.209.5 inside 192.168.2.100 80n")
