module: bigip_snmp_trap
short_description: Manipulate SNMP trap information on a BIG-IP.
description:
- Manipulate SNMP trap information on a BIG-IP.
version_added: 2.4
options:
name:
description:
- Name of the SNMP configuration endpoint.
required: True
snmp_version:
description:
- Specifies to which Simple Network Management Protocol (SNMP) version
the trap destination applies.
choices:
- 1
- 2c
community:
description:
- Specifies the community name for the trap destination.
destination:
description:
- Specifies the address for the trap destination. This can be either an
IP address or a hostname.
port:
description:
- Specifies the port for the trap destination.
network:
description:
- Specifies the name of the trap network. This option is not supported in
versions of BIG-IP < 12.1.0. If used on versions < 12.1.0, it will simply
be ignored.
choices:
- other
- management
- default
state:
description:
- When C(present), ensures that the cloud connector exists. When
C(absent), ensures that the cloud connector does not exist.
default: present
choices:
- present
- absent
notes:
- Requires the f5-sdk Python package on the host. This is as easy as pip
install f5-sdk.
- This module only supports version v1 and v2c of SNMP.
- The C(network) option is not supported on versions of BIG-IP < 12.1.0 because
the platform did not support that option until 12.1.0. If used on versions
< 12.1.0, it will simply be ignored.
extends_documentation_fragment: f5
requirements:
- f5-sdk >= 2.2.0
