Identifying IOS and NXOS

[rajthecomputerguy]

Hi Team,

I have 100 devices in host file, both IOS and NXOS mixed. I am trying pull OS details and hostname as report.   Since IOS and NXOS devices are mixed in inventory,  How can IOS_facts and NXOS_facts work in single playbook when there is no group in inventory.

I have only one group in inventory(both IOS and NXOS)

[cisco_devices]

rrtr1_ios

n9k_nexus

Thanks,

Raj

Any help would be appreciated

Well I assume you must have ansible_network_os variable for the hosts.  So you would just need to make 2 tasks, one for ios and one for nexus.

Then create a when statement

when: ansible_network_os is "ios"

Same for the nexus task just change it too nexus

You put the when statement at the task level.

I have only one group in inventory file which has IOS and NXOS devices mixed,   I can only set   ansible_network_os variable as 'IOS' 

[rajthecomputerguy]

Is there any solution for this?

Hello,

I don't think this is possible to achieve if you can _only_ set `ansible_network_os` to `ios`. The *_facts (or any network module with `connection: network_cli`) is dependent on the correct cliconf and terminal plugins being loaded which is identified by `ansible_network_os` value.

Thanks.

Since your target devices are restricted to IOS and NX-OS which share similarities in CLI structure, you can possibly do something like the following. However, this is not recommended at all and is not guaranteed to work. The correct approach is to fix your inventory and group the target hosts properly.

---
- hosts: cisco_devices
  gather_facts: false
  tasks:
    - name: Determine Network OS
      ansible.netcommon.cli_command:
        command: show version
      register: result
   
    - set_fact:
        ansible_network_os: nxos
      when: '"NXOS" in result.stdout'
   
    - meta: reset_connection

    - name: Gather IOS facts
      cisco.ios.ios_facts:
        gather_subset: ["hardware"]
      when: ansible_network_os == "ios"
   
    - name: Gather NX-OS facts
      cisco.nxos.nxos_facts:
        gather_subset: ["hardware"]
      when: ansible_network_os == "nxos"


Thanks.
