I’m using SNMP4J 2.8.0. I have a SNMP session which I use to send traps to extenal systems (only sending traps in this session, no other operations).
I use snmpv3 (AuthPriv) and USM model.
I would like to test a case when engineTime exceeds its maximum. I checked code and noticed that following methods are used to set engineTime in outgoing message:
According to RFC 2574 (&2.2.2) and comment in your method (org.snmp4j.security.UsmTimeTable#getEngineTime):
“If snmpEngineTime ever reaches its maximum value (2147483647), then snmpEngineBoots is incremented as if the SNMP engine has re-booted and snmpEngineTime is reset to zero and starts incrementing again.”
What I noticed during this test - engineTime was reset to zero but engineBoots was not incremented.
My question is: do you have handling of this case in SNMP4J or I need to implement it by myself i.e. by overriding USM class? Maybe you have some hints for me. Thanks
