SNMP FAQs 17.2
Q. Which version of SNMP is supported by the SNMP agent on the TempDefender G2?
A.
SNMP v1, SNMPv2 and SNMPv3.
Q. How do I configure the TempDefender G2 to send traps to an SNMP manager? Is there a separate MIB
for the TempDefender G2? How many SNMP managers can the agent send traps to? And how do I set
the IP address of the SNMP manager and the community string to be used when sending traps?
A. The TempDefender G2 begins sending traps as soon as the SNMP notification type is set up. The
TempDefender G2 MIB can be found on the DPS Telecom website. The MIB should be compiled on your SNMP
manager. (
Note: MIB versions may change in the future.) For step-by-step instructions, refer back to the "How
to Send SNMP Traps" section of the user manual.
Q. Does the TempDefender G2 support MIB-2 and/or any other standard MIBs?
A.
The TempDefender G2 supports the bulk of MIB-2.
Q. Does the TempDefender G2 SNMP agent support both TempDefender G2 and T/MonXM variables?
A.
The TempDefender G2 SNMP agent manages an embedded MIB that supports only the TempDefender G2's
RTU variables. The T/MonXM variables are included in the distributed MIB only to provide SNMP managers with
a single MIB for all DPS Telecom products.
Q. How many traps are triggered when a single point is set or cleared? The MIB defines traps like "major
alarm set/cleared," "RTU point set," and a lot of granular traps, which could imply that more than one
trap is sent when a change of state occurs on one point.
A. Generally, a single change of state generates a single trap.
Q. What does "point map" mean?
A.
A point map is a single MIB leaf that presents the current status of a 64-alarm-point display in an ASCII-readable
form, where a "." represents a clear and an "x" represents an alarm.
Q. The TempDefender G2 manual talks about control relay outputs. How do I control these from my
SNMP manager?
A. The control relays are operated by issuing the appropriate set commands, which are contained in the DPS
Telecom MIB.
Q. How can I associate descriptive information with a point for the RTU granular traps?
A.
The TempDefender G2 alarm point descriptions are individually defined using the Web Browser.
Q. My SNMP traps aren't getting through. What should I try?
A.
Try these three steps:
1. Make sure that the Trap Address (IP address of the SNMP manager) is defined. (If you changed the Trap
Address, make sure you saved the change to NVRAM and rebooted.)
2. Make sure all alarm points are configured to send SNMP traps.
3. Make sure the TempDefender G2 and the SNMP manager are both on the network. Use the unit's ping
command to ping the SNMP manager.
