aiSystemLastTrapSequenceNum
Module: AISYSTEM-MIB
OID (symbolic): AISYSTEM-MIB::aiSystemLastTrapSequenceNum
OID (numeric): 1.3.6.1.4.1.539.8.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This is the sequence number of the last trap sent by this agent. The sequence number starts at zero following a hardware reset or power-up. When the sequence number reaches 0xffffffff, it rolls over to 0 on the next trap. If the agent supports trap sequence numbers, it must include the trap sequence number when it sends traps and it must notify the CLC via a window transaction after each trap.
When this varbind appears in a trap, this is the sequence number of that trap.
What is aiSystemLastTrapSequenceNum?
Tracks the sequence number of the most recently sent SNMP trap from this agent, starting at zero after a reset and rolling over from 0xffffffff back to 0. This allows management systems to detect missed or out-of-order traps.
Examples
