Python ile Cisco Router ve Switchlerden Model/Seri Numarası/IOS Versiyonu Alma

Merhaba,

Aşağıda paylaşmış olduğum python fonksiyonu ile cisco router ve switch cihazlarınızdan “show version“ komutunun çıktısını kullanarak cihazlarınıza ait model, seri numarası ve ios versiyon bilgisini kolaylıkla alabilirsiniz.

def Cisco_CPE_Info(sh_ver):
    # Device type detect
    if "PID" in sh_ver:
        # If the detected device is a router
        sh_ver_parsed = sh_ver.split("\n")

        # Resetting the counters
        line, count = 0, 0
        
        # Getting the router ios version with regex
        router_ios = re.findall(r"flash.*:(.*).bin", sh_ver, re.IGNORECASE)[0]

        # Find router inventory info line
        for i in sh_ver_parsed:
            count += 1
            if "PID" in i:
                line = count+1
                break

        # Extract required data from inventory info line
        return_data = list(filter(None, sh_ver_parsed[line].replace("*", "").replace("\r", "").replace("\t", "").split(" ")))

        return [return_data[1], return_data[2], router_ios]
    else:
        # If the detected device is a switch
        sh_ver_parsed = sh_ver.split("\n")

        # Resetting the counters
        line, count = 0, 0
        
        # Getting the switch serial number with regex for switches with different IOS
        switch_serial = re.findall(r"System\ [S|s]erial\ [N|n]umber\s+\:\s(.*)", sh_ver, re.IGNORECASE)[0]

        # Find switch inventory info line
        for i in sh_ver_parsed:
            count += 1
            if "SW Version" in i:
                line = count+1
                break
        
        # Extract required data from inventory info line
        return_data = list(filter(None, sh_ver_parsed[line].replace("*", "").replace("\r", "").replace("\t", "").split(" ")))

        return [return_data[2], switch_serial, return_data[4]]
