description:
- Manage IPSec Traffic Selectors on BIG-IP.
version_added: 2.8
options:
name:
description:
- Specifies the name of the traffic selector.
type: str
required: True
destination_address:
description:
- Specifies the host or network IP address to which the application traffic is destined.
- When creating a new traffic selector, this parameter is required.
type: str
source_address:
description:
- Specifies the host or network IP address from which the application traffic originates.
- When creating a new traffic selector, this parameter is required.
type: str
ipsec_policy:
description:
- Specifies the IPsec policy that tells the BIG-IP system how to handle the packets.
- When creating a new traffic selector, if this parameter is not specified, the default
is C(default-ipsec-policy).
type: str
order:
description:
- Specifies the order in which traffic is matched, if traffic can be matched to multiple
traffic selectors.
- Traffic is matched to the traffic selector with the highest priority (lowest order number).
- When creating a new traffic selector, if this parameter is not specified, the default
is C(last).
