CiscoConfParse to json output

[anna]

Hi All,

I am trying to capture Interface,Description, Vlan,IP address,Subnet mark from huawei router configuration file.

"""
example script how to extract parameters from a Cisco IOS configuration using ciscoconfparse
"""
import json
from ciscoconfparse import CiscoConfParse
from ciscoconfparse.ccp_util import IPv4Obj

if __name__ == "__main__":
    # the result dictionary
    result = {
        "features": [],
        "interfaces": {}
    }

    confparse = CiscoConfParse("huwaieconf.txt")

    interface_cmds = confparse.find_objects(r"^interface ")

    # iterate over the resulting IOSCfgLine objects
    for interface_cmd in interface_cmds:
        # get the interface name (remove the interface command from the configuration line)
        intf_name = interface_cmd.text[len("interface "):]
        result["interfaces"][intf_name] = {}

        # search for the description command, if not set use "not set" as value
        result["interfaces"][intf_name]["description"] = "not set"
        for cmd in interface_cmd.re_search_children(r"^ description "):
            result["interfaces"][intf_name]["description"] = cmd.text.strip()[len("description "):]

        result["interfaces"][intf_name]["qos-profile"] = "n/a"
        for cmd in interface_cmd.re_search_children(r"^ qos-profile "):
            result["interfaces"][intf_name]["qos-profile"] = cmd.text.strip()[len("qos-profile"):]

        IPv4_REGEX = r"ip\saddress\s(\S+\s+\S+)"

        for cmd in interface_cmd.re_search_children(IPv4_REGEX):
            # ciscoconfparse provides a helper function for this task
            ipv4_addr = interface_cmd.re_match_iter_typed(IPv4_REGEX, result_type=IPv4Obj)

            result["interfaces"][intf_name].update({
                  "address": ipv4_addr.ip.exploded,
                  "netmask": ipv4_addr.netmask.exploded,
                  "network": ipv4_addr.network.exploded
            })

    print("\nEXTRACTED PARAMETERS\n")
    print(json.dumps(result, indent=4))
    data = json.dumps(result, indent=4)
    s = json.dumps(data)
    open("out.json","w").write(s)

sample output as below

Output:

            "vlan-type": "n/a"
        },
        "Eth-Trunk1": {
            "description": "TO DEL-CON-S5328EI-SW-A5 Eth-Trunk2",

        },
        "Eth-Trunk1.50": {

            "vlan-type": "n/a"

            "address": "111.93.33.9",
            "netmask": "255.255.255.252",
            "network": "111.93.33.8/30"
        },
        "Eth-Trunk1.120": {
            "description": "EXT_COGENT E SERVICES PRIVATE LIMITED_12005744750_50MB",
            "qos-profile": " 50Mbps outbound identifier none",
            "vlan-type": " dot1q 120",
            "address": "111.93.43.217",
            "netmask": "255.255.255.252",
            "network": "111.93.43.216/30"
        },
    }
}

my issue is, if interface is not having ip address, output should be printed as

"Eth-Trunk1.120": {
"description": "EXT_COGENT E SERVICES PRIVATE LIMITED_12005744750_50MB",
"qos-profile": " 50Mbps outbound identifier none",
"vlan-type": " dot1q 120",
"address": "n/a",
"netmask": "n/a",
"network": "na"
