Snmp Traps - Paradyne 3150 Operator's Manual

SNMP Traps

SNMP traps are unsolicited messages that are sent
from the CSU to an SNMP manager when the CSU
detects certain pre-specified conditions. These traps
enable the SNMP manager to monitor the state of the
network.
The SNMP Trap configuration option must be enabled
for trap messages to be sent over the communications
link. You must specify the number of SNMP managers
that are to receive traps from this CSU, an IP address for
each SNMP manager specified, and the type of traps to be
sent from this CSU. For more information, refer to
Appendix C, Configuration

SNMP Traps

section in Chapter 3, Operation.
Trap types consist of the following:
General traps – include warmStart and
authenticationFailure. The CSU sends a warmStart
trap after it has been reset to indicate that it has just
reinitialized itself. The CSU sends an
authenticationFailure trap when it has received an
SNMP protocol message that has not been properly
authenticated. These traps are set by the Gen Trap
configuration option.
Enterprise Specific traps – signify that the CSU
has recognized an enterprise-specific event. See
Table 4-4 for enterprise-specific traps. These traps
are set by the Entp Trap configuration option.
Link Traps – identify the condition of the
communications interface, either linkDown (one of
the communications interfaces has failed) or linkUp
(one of the communications interfaces has just
come up). These traps are set by the Link Trap
configuration option. The communications
interfaces for which these traps can be generated
are specified by the Trap I/F configuration option.
Table 4-5 defines traps for each interface.
