用python统计交换机有多少端口UP#xff0c;可以间接的反馈有多少个用户在线。我们使用上次的脚本将可达的网络设备ip统计到reachable_ip.txt中#xff0c;这次我们使用reachable_ip.txt来登陆设备来统计多少端口是UP的
云配置 拓扑 交换机…用python统计交换机有多少端口UP
用python统计交换机有多少端口UP可以间接的反馈有多少个用户在线。我们使用上次的脚本将可达的网络设备ip统计到reachable_ip.txt中这次我们使用reachable_ip.txt来登陆设备来统计多少端口是UP的
云配置 拓扑 交换机配置SSH
aaalocal-user admin password cipher Huawei123 //创建python用户密码为123local-user admin privilege level 15local-user admin service-type ssh
#
user-interface vty 0 4authentication-mode aaaprotocol inbound ssh
#
stelnet server enable
ssh user admin authentication-type all
ssh user admin service-type all
ssh client first-time enable这个时候我们就能与交换机互访并SSH登陆了
目的
用python统计交换机有多少端口UP可以间接的反馈有多少个用户在线。
代码
使用以下代码统计出有多少IP是可达的他会统计后写入到一个文本文件中也可以自己手动写或者写个循环
import pythonping # 导入 pythonping 库用于执行 ping 操作
import os # 导入 os 库用于操作文件和系统功能# 如果名为 reachable_ip.txt 的文件存在删除它
if os.path.exists(reachable_ip.txt):os.remove(reachable_ip.txt)ip_list range(2, 6) # 创建一个IP列表# 遍历IP列表
for ip in ip_list:ip 192.168.56. str(ip) # 构建IP地址ping_result pythonping.ping(ip) # 执行ping操作f open(reachable_ip.txt, a) # 打开 reachable_ip.txt 文件以追加模式写入if Reply in str(ping_result): # 检查ping结果中是否包含 Replyprint(ip is reachable.) # 如果包含 Reply打印IP地址是可达的f.write(ip \n) # 将可达的IP地址写入 reachable_ip.txt 文件中else:print(ip is not reachable.) # 如果不包含 Reply打印IP地址是不可达的f.close() # 关闭文件
192.168.56.2 is reachable.
192.168.56.3 is reachable.
192.168.56.4 is reachable.
192.168.56.5 is reachable.Process finished with exit code 0#检测到这些IP是可达的我们接下来用另外一个脚本去登陆上去进行统计正式统计交换机端口UP的数量的代码
