Viewing the Trap Event Log

The Trap Event Log displays all traps stored in the SNMP trap event log. ASCII trap strings used to describe trap events are provided in the tables contained in Standards Compliance for SNMP Traps (see Appendix B, SNMP MIBs and Traps, and RMON Alarm Defaults).

See Trap Event Log in Chapter 7, Operation and Maintenance, for a screen example and additional information.
