module: bigip_snmp
short_description: Manipulate general SNMP settings on a BIG-IP
description:
- Manipulate general SNMP settings on a BIG-IP.
version_added: 2.4
options:
allowed_addresses:
description:
- Configures the IP addresses of the SNMP clients from which the snmpd
daemon accepts requests.
- This value can be hostnames, IP addresses, or IP networks.
- You may specify a single list item of C(default) to set the value back
to the system's default of C(127.0.0.0/8).
- You can remove all allowed addresses by either providing the word C(none), or
by providing the empty string C("").
version_added: 2.6
contact:
description:
- Specifies the name of the person who administers the SNMP
service for this system.
agent_status_traps:
description:
- When C(enabled), ensures that the system sends a trap whenever the
SNMP agent starts running or stops running. This is usually enabled
by default on a BIG-IP.
choices:
- enabled
- disabled
agent_authentication_traps:
description:
- When C(enabled), ensures that the system sends authentication warning
traps to the trap destinations. This is usually disabled by default on
a BIG-IP.
choices:
- enabled
- disabled
device_warning_traps:
description:
- When C(enabled), ensures that the system sends device warning traps
to the trap destinations. This is usually enabled by default on a
BIG-IP.
choices:
- enabled
- disabled
location:
description:
- Specifies the description of this system's physical location.
