NXOS Netconf Port

NetDevOp — Thu, 10 Sep 2020 18:47:00 GMT

Hello all,

I am trying to connect to a couple of Nexus 9k's using Netconf. I get a response over port 22 and can pull the config but I don't see any configuration options or documentation on how to get the switches to use port 830. Any suggestions on how to do this?

Thanks

After you enabled the feature netconf, automatically the switch listens to port 830, you don't have to do anything.

Have you tried connecting on port 830 over ssh to valide the connection?

Here a link showing how to test it:

Hi @NetDevOp

The hard way (cli style):

client-host % ssh -s admin@<mgmt-ip-of-nexus> -p 830 netconf 
# netconf operations

The easy way (the ncclient python module):

from ncclient import manager

device = {
    "address": "<mgmt-ip-of-nexus>",
    "netconf_port": 830,
    "username": "admin",
    "password": "password"
}
with manager.connect(host = device["address"],
                         port = device["netconf_port"],
                         username = device["username"],
                         password = device["password"],
                         hostkey_verify = False) as m:
    # do your stuff

Stay safe,
