- Manages UDLD global configuration params.

author:

- Jason Edelman (@jedelman8)
|
|
notes:
|
|
- Tested against NXOSv 7.3.(0)D1(1) on VIRL
|
|
- When C(state=absent), it unconfigures existing settings C(msg_time) and set it
|
|
to its default value of 15. It is cleaner to always use C(state=present).
|
|
- Module will fail if the udld feature has not been previously enabled.
