4. Maintenance

If two alarm conditions are detected at once, the higher priority alarm is reported. However, if an even higher priority alarm is detected before the first alarm is cleared, the later alarm is not reported. (The alarms listed above are in priority order with the highest priority listed first.)

Alarms remain active until the alarm condition is cleared. Also, an alarm clear message is only sent when there are no other alarms active.

For information about alarm configuration options, refer to Alarm Configuration

Options in Appendix C, Configuration Options.

For troubleshooting information, refer to Troubleshooting on page 4-14.

SNMP Traps

SNMP traps are unsolicited messages that are sent from the DSU/CSU to an

SNMP manager when the DSU/CSU detects certain pre-specified conditions.

These traps enable the SNMP manager to monitor the state of the network.

he 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 DSU/CSU, an IP address for each SNMP manager specified, and the type of traps to be sent from this DSU/CSU. For more information, refer to Appendix C, Configuration Options, and Configuring SNMP Traps in Chapter 3, Operation.

Trap types consist of the following:

General traps – Include warmStart and authenticationFailure. The DSU/CSU sends a warmStart trap after it has been reset to indicate that it has just reinitialized itself. The DSU/CSU sends an authenticationFailure trap when it has received an SNMP protocol message that has not been properly

Tauthenticated. These traps are set by the Gen Trap configuration option.

Enterprise Specific traps – Signify that the DSU/CSU has recognized an enterprise-specific event. See Table 4-4,Enterprise-Specific Trap Definitions, for enterprise-specific traps. These traps are set by the Entp Trap configuration

Toption.

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, SNMP Trap per Interface, defines traps for each interface.
