Working with registered results

[madd...@gmail.com]

Hello all,  I have a group of switches that users keep asking me to locate mac address for in order to trace down the exact port and edit that port to a new vlan. Rather than logging into each switch and tracking down the switch where the mac resides, I created an ansible a basic ansible playbook to help me with this:

---

- name: Find mac address in sec-switches

  hosts: sec-switch

  gather_facts: false

  connection: local

  vars_prompt:

     - name: mac

       prompt: What is the mac address?

       private: no

  tasks:

    -

      name: debugging

      ansible.builtin.debug:

        msg: 'Searching for {{ mac }}'

    -

      name: "search"

      register: output

      ios_command:

        commands:

          - "show mac address-table | include {{ mac }}"

    -

      debug: var=output.stdout_lines

When ran, my debug gives me:

(snippet)

}

ok: [10.1.1.32] => {

    "output.stdout_lines": [

        [

            "24    0050.f967.5cb7    DYNAMIC     Gi1/0/48"

        ]

    ]

}

ok: [10.1.1.33] => {

    "output.stdout_lines": [

        [

            "24    0050.f967.5cb7    DYNAMIC     Gi1/0/48"

        ]

    ]

}

ok: [10.1.1.30] => {

    "output.stdout_lines": [

        [

            "4    0050.f967.5cb7    DYNAMIC     Gi1/1/1",

            " 24    0050.f967.5cb7    DYNAMIC     Gi1/1/1"

        ]

    ]

}

I'd like to filter the output and for each switch run the sh interfaces description | inc { using the returned interfaces}. This way I can rule out uplinks.

IE:  On switch 10.1.1.33 I ran: sh interfaces description | inc Gi1/0/48

and it returned: Gi1/0/48                       up             up       UPLINK

 

That lets me know I don't need to worry about that switch as its an uplink.

Any help would be appreciated. I looked into https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html

I tried seeing if my returned output was a dictionary, but the playbook complained when I added {{ myvar | type_debug }} under my debug statement as: {{ output | type_debug }}

Thanks in advance.

I'm getting closer using regex...trying to tweak the regex now (Still any help would be appreciated):

---

- name: Find mac address in sec-switches

  hosts: sec-switch

  gather_facts: false

  connection: local

  vars_prompt:

     - name: mac

       prompt: What is the mac address?

       private: no

  tasks:

    -

      name: debugging

      ansible.builtin.debug:

        msg: 'Searching for {{ mac }}'

    -

      name: "search"

      register: output

      ios_command:

        commands:

          - "show mac address-table | include {{ mac }}"

      register: printout

    - set_fact:

        intf: |

          {{printout.stdout_lines[0] |

            map('regex_replace','^(?:[^ ]*\ ){12}([^ ]*)') |

            list }}

    - name: View output

      debug:

        var: intf

Here is my output:

 ________________________

< TASK [View output] >

 ------------------------

        \   ^__^

         \  (oo)\_______

            (__)\       )\/\

                ||----w |

                ||     ||

ok: [10.1.1.38] => {

    "intf": [

        " Gi1/0/49"

    ]

}

I still need to get rid of: [ and whitespace

[Rajthecomputerguy]

Use strip() method to get rid of whitespace

      debug:

        var: intf[0].strip()

Thanks,

Thanks  Pushparaj, I'll give that a try & let you know

[madd...@gmail.com]

That worked! Thank you very much  Pushparaj, you are the man!

To take it one step further, in the output. I'd like to remove any results that have "UPLINK" in them

I have tried the following below, but "{{ intf_corrected2 }}" doesn't show me what  I'm expecting.

I'm expecting to see just the one switch which has the mac and the port isn't an uplink. Below is where I'm at:

---

- name: Find mac address in sec-switches

  hosts: sec-switch

  gather_facts: false

  connection: local

  vars_prompt:

     - name: mac

       prompt: What is the mac address?

       private: no

  tasks:

    -

      name: debugging

      ansible.builtin.debug:

        msg: 'Searching for {{ mac }}'

    -

      name: search

      ios_command:

        commands:

          - "show mac address-table | include {{ mac }}"

      register: printout

    - set_fact:

        intf: |

          {{printout.stdout_lines[0] |

            map('regex_replace','^(?:[^ ]*\ ){12}([^ ]*)') |

            list }}

    - set_fact:

        intf_corrected1={{ intf[0].strip() }}

    - debug:

        msg: "{{ intf_corrected1 }}"

    -

      name: show int desc

      ios_command:

        commands:

          - "sh interfaces description | inc {{ intf_corrected1 }}"

      register: printout2

    - name: View output

      debug:

        var: printout2

    - set_fact:

        intf_corrected2: |

          {{printout2 |

            map('regex_replace','^((?!UPLINK|uplink).)*$') |

            list }}

    - name: View output

      debug:

        msg: "{{ intf_corrected2 }}"
