SNMP Trap: Mailbox Status

A trap is generated when the local mailbox reaches 200 plus emails.

Identification

  • The originating IP / hostname is used to identify the system generating the traps
  • The NMS is responsible for associating traps with each managed system, along with clearing of alarms and escalation to the relevant system operator
  • The trap OID is generic for various SNMP events monitored by the system
  • The SNMP system name is included as part of the variable binding to assist identification:
.iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone
