module: nxos_acl

version_added: "2.2"
|

short_description: Manages access list entries for ACLs.

description:

- Manages access list entries for ACLs.

extends_documentation_fragment: nxos

author:

- Gabriele Gerbino (@GGabriele)
|
|
notes:
|
|
- C(state=absent) removes the ACE if it exists.
|
|
- C(state=delete_acl) deleted the ACL if it exists.
|
|
- For idempotency, use port numbers for the src/dest port
|
|
params like I(src_port1) and names for the well defined protocols
|
|
for the I(proto) param.
|
|
- Although this module is idempotent in that if the ace as presented in
|
|
the task is identical to the one on the switch, no changes will be made.
|
|
If there is any difference, what is in Ansible will be pushed (configured
|
|
options will be overridden). This is to improve security, but at the
|
|
same time remember an ACE is removed, then re-added, so if there is a
|
|
change, the new ACE will be exactly what paramaters you are sending to
|
|
the module.
