Configuring NETCONF: Cisco C9800 WLC

By 4 Comments

As I begin looking into Python and the DevNet materials, I’ve been wanting to utilize my own lab in order for me to run various tests against. I also wanted it to be closer to Wi-Fi, aside from testing against Meraki’s Sandbox.

So to get started, I figured the Cisco C9800-CL would be a good place to start. I’ve been using it to test Wi-Fi 6 and now I can use it to test my Python knowledge.

Do you find this content useful? If so, consider buying me a coffee! ☕

Configure NETCONF

First thing we need to do is enable NETCONF-YANG on the C9800-CL. This is very easy to do.

First, let’s see what’s running by running show platform software yang-management process

WLC#show platform software yang-management process
confd            : Not Running
nesd             : Not Running
syncfd           : Not Running
ncsshd           : Not Running
dmiauthd         : Not Running
nginx            : Running
ndbmand          : Not Running
pubd             : Running
gnmib            : Not Running

Ok, NETCONF-YANG is not running. Only nginx and pubd are running. We need all the processes running except for gnmib.

Enabling NETCONF-YANG is simple with this config command: netconf-yang

To do that type in the following commands and verify:

WLC#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
WLC(config)#
WLC(config)#netconf-yang
WLC(config)#exit
WLC#
WLC#
WLC#show platform software yang-management process
confd            : Running
nesd             : Running
syncfd           : Running
ncsshd           : Running
dmiauthd         : Running
nginx            : Running
ndbmand          : Running
pubd             : Running
gnmib            : Not Running

That’s it. Now I have to figure out how to use NETCONF-YANG models 😂

  1. Use the YANGExplorer, Cisco YANGSuite, Advanced Netconf Explorer, pyang… etc work working with the data models

    • I’ve heard of some of those. Haven’t gotten around to using them yet but now is a good time to start.

  2. from ncclient import manager

    wlc=’xx.xx.xx.xx’
    user=’xx’
    password=’xx’
    netconf_connection=manager.connect(host=wlc,
    port=830,
    username=user,
    password=password,
    hostkey_verify=False,
    device_params={‘name’:’csr’},
    timeout=300)
    print(netconf_connection)

    I got an erro informaiton:
    raise SSHError(“Could not open socket to %s:%s” % (host, port))
    ncclient.transport.errors.SSHError: Could not open socket to 10.124.55.34:830

    is there something wrong with this code?
