Module: SNMPv2-USEC-MIB
OID (symbolic): SNMPv2-USEC-MIB::usecStatsNotInWindows
OID (numeric): 1.3.6.1.6.3.6.1.2.2
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The total number of packets received by the SNMPv2 entity which were dropped because they appeared outside of the agent's window.
What is usecStatsNotInWindows?
This is a cumulative count of packets dropped because their timestamp fell outside the agent's accepted USM time window. An admin watches this for clock-skew issues between manager and agent, or for possible replay-attack attempts. For example, a spike here after a manager's clock jumps could indicate agentBoots/agentTime desynchronization between the two systems.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.6.3.6.1.2.2 snmpwalk -v2c -c public <target> SNMPv2-USEC-MIB::usecStatsNotInWindows
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.6.3.6.1.2.2.1 snmpget -v2c -c public <target> SNMPv2-USEC-MIB::usecStatsNotInWindows.1
