Expect while 循环中的多个 telnet 连接

Expect while 循环中的多个 telnet 连接

我需要获取文件中列出的某些设备的序列号,如下所示:

device_id,ip_address
 BIOTERIO, 148.000.00.189
 N7K-LAN(JAF1651ANDL), 148.000.0.192
 LAB_PESADO, 148.000.000.130
 Arquitectura_Salones, 148.000.000.61
 CIVIL_253, 148.000.000.253 
 Arquitectura, 148.000.000.253
 ING_CIVIL, 148.000.000.251
 ING_CIVIL_DIR, 148.000.0.188
 Ingenieria_Posgrado, 148.000.000.253
 Biblio_Barragan, 148.000.000.61
 Electronica_Edif_3, 148.000.000.253

我不知道如何进行循环,但我需要它通过 telnet 连接到每个设备,使用特定的用户名和密码,然后运行此 cisco 命令“ show version”并将序列号保存在同一个文件中(如果可能) 。

知道我该怎么做吗?

#!/usr/bin/env expect

# open first argument to program...
set fd [open [lindex $argv 0]]

# for each line using that file handle...
while {[gets $fd line] >= 0} {
    # split on , and select the last one...
    set lastcolumn [lindex [split $line ","] end]
    # whoops there's some whitespace so clear that...
    set ip [string trim $lastcolumn " "]
    puts ">$ip<"
}
