Display specific lines from cisco output

[Raheel Khilji]

I have a situation my script is 

hosts: Branch

  gather_facts: false

  connection: local

  tasks:

   - name: Facts

     ios_command:

        commands:

                - show inter gi0/0

     register: output

   - debug:

       msg: "{{ output.stdout_lines }}"

 

## The output is like....

"GigabitEthernet0/0 is up, line protocol is up ",

            "  Hardware is CN Gigabit Ethernet, address is d8b1.

            "  Description: ***LAN***",

            "  MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec, ",

            "  Encapsulation 802.1Q Virtual LAN, Vlan ID  1., loopback not set",

            "  Keepalive set (10 sec)",

            "  Last clearing of \"show interface\" counters never",

            "  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0",

            "  Queueing strategy: fifo",

            "  5 minute input rate 64000 bits/sec, 46 packets/sec",

            "     64022727 packets input, 3777167804 bytes, 0 no buffer",

            "     Received 7566193 broadcasts (0 IP multicasts)",

            "     0 runts, 0 giants, 0 throttles ",

            "     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored",

            "     0 watchdog, 904385 multicast, 0 pause input",

            "     60376363 packets output, 1696679415 bytes, 0 underruns",

            "     0 output errors, 0 collisions, 0 interface resets",

            "     115659 unknown protocol drops",

            "     0 babbles, 0 late collision, 0 deferred",

            "     0 lost carrier, 0 no carrier, 0 pause output",

            "     0 output buffer failures, 0 output buffers swapped out"

But how can i display an specific line rather then whole output as i want the lines starts with "5 minute"

Please Help

You could use ansible-network.network-engine's command_parser. The example is on show interfaces.

I published more example on my github: https://github.com/kvernNC/cisco_config_parser/blob/master/README.md

Can you please explain me in detail because i have tried the solution but failed. Please help me

As I said , the documentation is about what your trying to do : https://github.com/ansible-network/network-engine/blob/devel/docs/user_guide/command_parser.md, but on show interfaces with a loop, not on a specific interface.

For your example, without loop, It should be something like this (not tested) :

1°) playbook 

hosts: Branch

  gather_facts: false

  connection: local

  tasks:

   - name: Facts

     ios_command:

        commands:

                - show inter gi0/0

     register: output

   - command_parser:

        file: "parser_templates/ios/show_interfaces.yaml"

    content: "{{ output.stdout.0 }}"

   - debug:

       var: input_rate.matches

  

   - debug:

       var: output_rate.matches

   

2°) content of the template:

---

- name: parser meta data

  parser_metadata:

    version: 1.0

    command: show interfaces <>

    network_os: ios

- name: match input rate 

  pattern_match:

    regex: "^ 5 minute input rate ([^,]+),"

  register: input_rate

  export: yes

 

- name: match output rate 

  pattern_match:

    regex: "^ 5 minute output rate ([^,]+),"

  register: output_rate

  export: yes

value registered are regex group, in (), each group is stored in matches dot is number.

command_parser read line by line and if the regex match, store the result in a var than you can use in playbook only if you use export:yes.
