CP560 DVB-T2 Gateway User’s Manual Rev. 2.2 (3686) ID: um_t2gateway
9.4.2 Trap destination table
The Trap Destination table lets the user configure the external entities that should receive SNMP
traps from the device. The table is both accessible via VIGW-UNIT-MIB and the product GUI
(Device Info/SNMP settings). A maximum of 8 different destinations are supported.
9.4.3 Trap configuration
All supported traps are currently defined in the VIGW-UNIT-MIB. Via the GUI you can control
the trap forwarding. For detailed information about each trap and the corresponding variable
bindings, please see
Section 9.5.
Trap version
This parameter controls the TRAPs that will be sent from the device in case of alarm
conditions.
SNMPv1 (Legacy)
If this option is selected, the unit will send the traps located under the vigwLegacy-
Traps MIB node. These traps are included mostly for historical reasons and it is not
recommended to use these for new deployments.
SNMPv2
This is the recommended setting. The traps defined under the node unitNotifi-
cations will be used while the traps under the node vigwLegacyTraps will be
disabled.
Status change traps
If enabled, the unit will transmit unitAlarmStatusChanged traps whenever the top level
alarm status is changed for the unit.
Alarm event forwarding
This setting controls how internal alarm event will be forwarded as TRAP messages. Adjust
this value if you want to control the number of traps sent from the unit. The settings are
only used when SNMPv2 is selected as TRAP version. The settings are:
Disabled
No specific event traps are transmitted when alarms are raised or cleared. (The
unitAlarmStatusChanged trap may however be transmitted).
Basic
The device forwards alarms as traps on a basic level. No information about subid3
will be transmitted.
Detailed
The device forwards alarms as traps. If there are sub-entries that are using the subid3
value, each sub.entry will be transmitted in separate trap messages.
