description:
- Network policy specifies layer 2 security settings for a
portgroup such as promiscuous mode, where guest adapter listens
to all the packets, MAC address changes and forged transmits.
- Dict which configures the different security values for portgroup.
- 'Valid attributes are:'
- '- C(promiscuous_mode) (bool): indicates whether promiscuous mode is allowed. (default: false)'
