How to use get_interfaces_ip() and get_conf() features in NAPALM in the same code

691 views Asked by At

My purpose in this code is to detect interfaces with L3 IP under the "Virtual-ethernet" interfaces in a NE40 Huawei device. I was able to do this step. As I mentioned below, my question is, How can I see the configurations of these interfaces with get_device() or a different method? Or should I use a different library with Napalm?

First part of code :

from napalm import get_network_driver

driver = get_network_driver('huawei_vrp')
device = driver(hostname='X.X.X.X', username='admin', password='admin')
device.open()

get_interfaces_ip = device.get_interfaces_ip()
get_config_device = device.get_config()

for i in get_interfaces_ip:
        if "Virtual-Ether" in i:
            print(i)

print(i) Output:

Virtual-Ethernet3/0/1.3083
Virtual-Ethernet3/0/1.3086
Virtual-Ethernet3/0/1.3087
Virtual-Ethernet3/0/1.3090
Virtual-Ethernet3/0/1.3091

Full code: ( Added get_config() feature to code)

from napalm import get_network_driver

driver = get_network_driver('huawei_vrp')
device = driver(hostname='X.X.X.X', username='admin', password='admin')
device.open()

get_interfaces_ip = device.get_interfaces_ip()
get_config_device = device.get_config()

for i in get_interfaces_ip:
        if "Virtual-Ether" in i:
            #print(i)
            interface_config = get_config_device[i]
            print(interface_config)

print(interface_config) Error received :

[appadmin@ryugbz01 Huawei]$ python3 napalm_vrp_huawei_conf.py
Virtual-Ethernet3/0/1.24
Traceback (most recent call last):
  File "napalm_vrp_huawei_conf.py", line 19, in <module>
    interface_config = get_config_device[i]
KeyError: 'Virtual-Ethernet3/0/1.24'

In the last part, with the get_config() feature, I cannot see the configurations under Virtual-Ethernet3/0/1.24 interface, for example. What method should I apply?

Maybe the following script can give an idea.

#To install napalm-ce you just have to run the following command: 'pip install napalm-ce'

import napalm
from tabulate import tabulate
 
def main():
 
    driver_vrp = napalm.get_network_driver("ce")

    device_list = [["vrp-sw1","vrp", "switch"],["vrp-r1", "vrp", "router"]]
 
    network_devices = []
    for device in device_list:
            network_devices.append(
                            driver_vrp(
                            hostname = device[0],
                            username = "admin",
                            password = "admin"
                            )

                ])
        
        print("Getting device config")

        device.close()
