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 Options , and Configuring SNMP
Traps in Chapter 4, Configuration .
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 7-5, Enterprise-Specific Trap Definitions ,
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 7-6, SNMP Trap per Interface , defines traps for each interface.
