- name: change MTU
hosts: router
connection: local
vars:
mtu_1: 'MTU is 1500'
contents: "{{ lookup('file', '/home/marcin/var.json') }}"
tasks:
- name: show ip interface et0/0
ios_command:
commands:
- sh ip interface et0/0
provider: "{{ cli }}"
register: showrun
- copy: content="{{ showrun.stdout_lines | to_nice_json }}"
dest="/home/marcin/show.json"
- name: grep
shell: grep -Eo "([A-Z])\w+\s\is\s[0-9]+" /home/marcin/show.json
register: my_grep
- copy: content="{{ my_grep.stdout }}" dest="/home/marcin/var.json"
- debug: var=contents
- name: change MTU if smaller then 1500
ios_config:
lines:
- ip mtu 1500
parents: interface ethernet0/0
provider: "{{ cli }}"
when:
- contents != mtu_1
- debug: msg="MTU mismatch"
when:
- contents != mtu_1
- debug: msg="MTU match"
