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, but there are two exceptions to this rule.
Exception 1: the first alarm in an all clear condition generates an additional summary point set trap.
Exception 2: the final clear alarm that triggers an all clear condition generates an additional summary point
clear 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 NetGuardian manual talks about eight 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. For more information about the set commands, see Reference Information, Display Mapping,
in any of the NetGuardian software configuration guides.
Q. How can I associate descriptive information with a point for the RTU granular traps?
A. The NetGuardian alarm point descriptions are individually defined using the Web Browser Interface, TTY,
or Edit216T configuration interfaces.
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 NetGuardian and the SNMP manager are both on the network. Use the NetGuardian's
ping command to ping the SNMP manager.

Q. What do I need to do to set up email notifications?
A. You need to assign the NetGuardian an email address and list the addresses of email recipients. Let's explain
some terminology. An email address consists of two parts, the user name (everything before the @ sign) and
the domain (everything after the @ sign). To assign the NetGuardian an email address, choose System from
the Edit menu. Enter the NetGuardian's user name in the Name field (it can't include any spaces) and the
domain in the Location field. For example, if the system configuration reads:
Name: netguardian
Location: proactive.com
Then email notifications from the NetGuardian will be sent from the address netguardian@proactive.com.
The next step is to list the email recipients. Choose Pagers from the Edit menu. For each email recipient,
enter his or her email domain in the Phone/Domain field and his or her user name in the PIN/Rcpt/Port field.
You must also enter the IP address of an SNMP server in the IPA field.
