description:

|
- Manages AAA server global configuration
|
|
author:
|
|
- Jason Edelman (@jedelman8)
|
|
notes:
|
|
- Tested against NXOSv 7.3.(0)D1(1) on VIRL
|
|
- The server_type parameter is always required.
|
|
- If encrypt_type is not supplied, the global AAA server key will be
|
|
stored as encrypted (type 7).
|
|
- Changes to the global AAA server key with encrypt_type=0
|
|
are not idempotent.
|
|
- If global AAA server key is not found, it's shown as "unknown"
|
|
- state=default will set the supplied parameters to their default values.
|
|
The parameters that you want to default must also be set to default.
|
|
If global_key=default, the global key will be removed.
