Snmp Traps - Paradyne 3172 Operator's Manual

ACCULINK 3172 and 3174 E1 DSU/CSU

SNMP Traps

A trap is an unsolicited message that is sent from the
E1 DSU/CSU to an SNMP manager when the device
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 device, an IP address for
each SNMP manager specified, and the type of traps to be
sent from this device. 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 device sends a
warmStart trap after it has been reset to indicate
that it has just reinitialized itself. The device 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 device
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.

Trap Meaning
Up = No alarm conditions.
Down = Alarm conditions.
Up = No alarm conditions
and interface is enabled.
