virtual_server_ports:
description:
- A list of ports to create for the virtual server. Each list item should be a
dictionary which specifies the C(port:) and C(type:), but can also optionally
specify the C(service_group:) as well as the C(status:). See the examples
below for details. This parameter is required when C(state) is C(present).
required: false
write_config:
description:
- If C(yes), any changes will cause a write of the running configuration
to non-volatile memory. This will save I(all) configuration changes,
including those that may have been made manually or through other modules,
so care should be taken when specifying C(yes).
required: false
default: "no"
choices: ["yes", "no"]
validate_certs:
description:
- If C(no), SSL certificates will not be validated. This should only be used
on personally controlled devices using self-signed certificates.
required: false
