6.2.2 SNMP Traps
Use of SNMP Traps allow the network manager to set conditions (alarms) under which the device
(or devices) autonomously report to the headend the existence of the pre-congured event. The
type of event determines the level of action to be taken.
1. Verify the IP address of the trap destination server(s) has been congured.
If the trap destination server requires conguration, refer to Section 3.2.2, "Setting SNMP
Trap Destination Addresses" for instructions.
2. Alarms must be congured. SNMP alarm traps sent by the transponder are formatted
according to the SCTE-HMS-ALARM-MIB specication with the following
information included:
SNMP Trap community string:
commonTrapCommunityString, OID 1.3.6.1.4.1.5591.1.3.1.11.0
Default value is "public"
Example Alarm Trap
The example below is a psTamper alarm trap indicating a discreteMinor alarm: Tamper is open.
Data from the raw trap will appear as shown below. Refer to Table 6-6 "SNMP Alarm Trap
Varbinds and Explanations" for denitions of the varbinds.
