SNMP managers, which is configured by selecting the secondary SNMP managers as pager recipients.
Community strings are configured globally for all SNMP managers. To configure the community strings,
choose System from the Edit menu, and enter appropriate values in the Get, Set, and Trap fields.
Q. Does the NetDog support MIB-2 and/or any other standard MIBs?
A. The NetDog supports the bulk of MIB-2.
Q. Does the NetDog SNMP agent support both NetDog and T/MonXM variables?
A. The NetDog SNMP agent manages an embedded MIB that supports only the NetDog'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, but there are two exception 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 NetDog manual talks about two 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 Appendix, "Display Mapping," in any of
the NetDog software configuration guides.
Q. How can I associate descriptive information with a point for the RTU granular traps?
A. The NetDog alarm point descriptions are individually defined using the Web Browser or TTY 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 NetDog and the SNMP manager are both on the network. Use the NetDog's ping
command to ping the SNMP manager.
Pager FAQs

Q. Why won't my alpha pager work?
A. To configure the NetDog to send alarm notifications to an alpha pager, enter the data phone number for your
pager in the Phone Number field. This phone number should connect to your pager service's modem. Then
enter the PIN for your pager in the PIN/Rcpt/Port field. You don't need to enter anything in any of the other
fields. If you still don't receive pages, try setting the Dial Modem Init string to ATS37=9. This will limit the
NetDog's connection speed.
Q. Numeric pages don't come in or are cut off in the middle of the message. What's wrong?
A. You need to set a delay between the time the NetDog dials your pager number and the time the NetDog
begins sending the page message. You can set the delay in the Pager Number field, where you enter your
pager number. First enter the pager number, then enter some commas directly after the number. Each comma
