Hi ,
Software Version : net-snmp-5.3.0.1
Operating System : Linux ( Windriver linux)
Problem Description : snmp client is sending Inform with engineBoots
31 and snmp server is responding with report engineBoots 34 with
filed usmStatsNotInTimeWindows .
But snmp clinet is not using the engineBoots sent in report from server
and continue to send inform with old engineBoots and time as if there is
no report received.
Procedure : snmp client was up for more than 3 months and server went donw
& came up three times which cause the engineBoots to increase form 31 to 34
and after this the snmp communication is broken. This behaviour is observed
randomly but not consistent.
Below pattern in repeated forever. Attached the
Repor_usmStatsNotInTimeWindows_Not-working.txt which is text form of the
tcpdump at snmp client.
