eventSeqNum
Module: ZYXEL-GS4012F-MIB
OID (symbolic): ZYXEL-GS4012F-MIB::eventSeqNum
OID (numeric): 1.3.6.1.4.1.890.1.5.8.20.36.1.1.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This variable represents the sequence number of an event. Sequence number is incremented monotonically starting from 0 until it reaches its maximum and wraps around back to 0.
Sequence number is incremented when - the state of a normal type fault is set on (the same sequence number is present in the events table as well as in the trap that is sent to notify about the fault on event) - delta event occurs (sequence number present in trap message) - the state of a normal type fault is set off (sequence number present in trap that is sent to notify for clearing).
What is eventSeqNum?
The sequence number of an event, which rises monotonically from 0, wraps around at its maximum, and increments when the state of a normal fault is set on. Compare it with the last number you saw to detect missed events or traps.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.890.1.5.8.20.36.1.1.1.1 snmpwalk -v2c -c public <target> ZYXEL-GS4012F-MIB::eventSeqNum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.890.1.5.8.20.36.1.1.1.1.1 snmpget -v2c -c public <target> ZYXEL-GS4012F-MIB::eventSeqNum.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> eventSeqNum.1
