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

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.539.8.2
snmpwalk -v2c -c public <target> AISYSTEM-MIB::aiSystemLastTrapSequenceNum

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.539.8.2.1
snmpget -v2c -c public <target> AISYSTEM-MIB::aiSystemLastTrapSequenceNum.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> aiSystemLastTrapSequenceNum.1
