Ansible gather_subset for NXOS failing with command timeout triggered

secureB00T — Fri, 17 Feb 2023 19:40:58 GMT

Hi all,

Hopefully someone might be able to help out. I've been wrestling with this for a while. I'm fairly new to ansible and trying to run a playbook against a pair of nexus switches that will change the description of ports based on the information it gets from cisco.nxos.nxos_facts ( using cdp neighbor information). I've run this in a lab environment successfully but when running against our live environment, it fails.

This is the playbook i'm trying to run:

********************************************************************************************************************************

---

- name: Set interface description based on CDP/LLDP discovery

hosts: SDS

gather_facts: yes

connection: network_cli

tasks:

- name: GATHER ALL NXOS LEGACY FACTS

cisco.nxos.nxos_facts:

gather_subset:

- all

gather_network_resources:

- all

# log messages to specified folder

vars:

ansible_persistent_log_messages: True

- name: VIEW facts gathered

debug:

var: ansible_facts.keys()

- name: VIEW CDP/LLDP NEIGHBORS

debug:

var: ansible_facts.net_neighbors

# - name: SET NXOS INTERFACE DESCRIPTIONS

# nxos_config:

# lines:

# - description {{item.value[0].host.split('.').0}}:{{item.value[0].port[0:3]}}{{item.value[0].port.split('t')[-1]}}

# parents: interface {{item.key}}

# save_when: changed

# with_dict: "{{ansible_facts.net_neighbors}}"

# when: ansible_network_os == 'nxos'

********************************************************************************************************************************

I've commented out the bottom portion until I get the 'gather_subset' part working. in the meantime, the error messages I get are these:

The full traceback is:

Sorry for the long information but hope this helps. If you need some more information to assist, I'll be happy to provide it. I've looked at documentation but like I said, I'm very new to ansible and still learning. Thanks in advanced for your help.

Increase the command timeout, see https://docs.ansible.com/ansible/latest/network/getting_started/network_connection_options.html

I prefer using a local ansible.cfg in the root of every project folder:

[persistent_connection]
command_timeout = 240

But all the options described in the link above will work.

Hi @Marcel Zehnder ,

Thank you for your response! I had actually tried this method of changing the time, and before i went up to 120. I changed as you suggested to 'command_timeout = 240' and it worked!! So thank you for that, one step closer. I guess it needed more time to gather facts since they are connected to A LOT of devices.

Now the next step, is changing the ports description. I uncommented those sections and the script gathered all the information but ended up 'skipping' the part for changing the ports.

Here's a small snippet of a few interfaced that failed to change and the reason why:

skipping: [SDS-01] => (item={'key': 'Ethernet8/40', 'value': [{'port': 'TenGigabitEthernet1/1/4', 'host': 'SBS-I-20.company.com', 'sysname': 'SBS-I-20.company.com'}]}) => {
"ansible_loop_var": "item",
"changed": false,
"item": {
"key": "Ethernet8/40",
"value": [
{
"host": "SBS-I-20.company.com",
"port": "TenGigabitEthernet1/1/4",
"sysname": "SBS-I-20.company.com"
}
]
},
"skip_reason": "Conditional result was False"
}
skipping: [SDS-01] => (item={'key': 'Ethernet8/41', 'value': [{'port': 'TenGigabitEthernet1/1/3', 'host': 'SBS-K-10.company.com', 'sysname': 'SBS-K-10.company.com'}]}) => {
"ansible_loop_var": "item",
"changed": false,
"item": {
"key": "Ethernet8/41",
"value": [
{
"host": "SBS-K-10.company.com",
"port": "TenGigabitEthernet1/1/3",
"sysname": "SBS-K-10.company.com"
}
]
},
"skip_reason": "Conditional result was False"
}

***************************************

So basically, something in this task (shown below) is throwing off a condition and skipping the rest, but the only condition I can think of is "when: ansible_network_os == 'nxos'" .

- name: SET NXOS INTERFACE DESCRIPTIONS

nxos_config:

lines:

- description {{item.value[0].host.split('.').0}}:{{item.value[0].port[0:3]}}{{item.value[0].port.split('t')[-1]}}

parents: interface {{item.key}}

save_when: changed

with_dict: "{{ansible_facts.net_neighbors}}"

when: ansible_network_os == 'nxos'

Hi the ansible_network_os is 'cisco.nxos.nxos' not 'nxos'.

@Marcel Zehnder

That was it!! Wow, just one little piece of syntax. Awesome, got my script to run successfully, and ports labeled accordingly based on their cdp info. I was working on it for quite a while, thanks a lot for your help, much appreciated!!
