SUMMARY

When the hostname + domain name gets long the lldp neighbor output truncates at 20 characters. The result is no record being created and getting a blank completion.

Sample output of NTC Templates with network engine as is:

TASK [CLI >> Get LLDP neighbors] *********************************************************************************************************************************************************************************
ok: [rtr01]

TASK [SYS >> Parse LLDP Information] *****************************************************************************************************************************************************************************
ok: [rtr01]

TASK [DEBUG >> LLDP Neighbors] ***********************************************************************************************************************************************************************************
ok: [rtr01] => {
    "msg": []
}

PLAY RECAP *******************************************************************************************************************************************************************************************************
rtr01                      : ok=3    changed=0    unreachable=0    failed=0

STEPS TO REPRODUCE

- name: Switch config
  connection: network_cli
  hosts: cisco_routers
  gather_facts: no
  become: yes
  become_method: enable
  roles:
    - ansible-network.network-engine

  tasks:

    - name: CLI >> Get LLDP neighbors
      ios_command:
        commands:
          - show lldp neighbors
      register: command_output

    - name: SYS >> Parse LLDP Information
      textfsm_parser:
        file: "/opt/ntc-templates/templates/cisco_ios_show_lldp_neighbors.template"
        content: "{{ command_output.stdout[0] }}"
        name: lldp_facts

    - name: DEBUG >> LLDP Neighbors
      debug:
        msg: "{{ ansible_facts.lldp_facts }}"

EXPECTED RESULTS

I expect to see a neighbor in the output

ACTUAL RESULTS

I got a blank facts set as shown above.
