用python写查询交换机的端口和能修改交换机网段的程序

查询交换机端口的程序：

import telnetlib

HOST = "192.168.0.1"  # 交换机IP地址
user = "admin"  # 交换机用户名
password = "password"  # 交换机密码

tn = telnetlib.Telnet(HOST)

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

tn.write(b"show interfaces status\n")
output = tn.read_until(b"switch#").decode('ascii')

print(output)

tn.write(b"exit\n")

修改交换机网段的程序：

import telnetlib

HOST = "192.168.0.1"  # 交换机IP地址
user = "admin"  # 交换机用户名
password = "password"  # 交换机密码

tn = telnetlib.Telnet(HOST)

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

tn.write(b"configure terminal\n")
tn.write(b"interface vlan 1\n")  # 假设要修改的网段是VLAN1
tn.write(b"ip address 192.168.1.1 255.255.255.0\n")  # 新的网段和子网掩码
tn.write(b"exit\n")
tn.write(b"exit\n")

print("网段修改成功！")

tn.close()
