[SNMP4J] Time Window Error - Possible Bug?

[Angie Fernandez]

Thanks Everyone!  I changed the engine id in the Test Agent and it works
now.  However, since all agents and managers must have unique engine
ids, is there any standard way to create engine ids such that uniqueness
is guaranteed?

Thanks,
Angie Fernandez

HI,

Because you are using the TestAgent and the SNMP4J command
line tool which use the same engine ID by default, you
are getting this error. Just specify a different engine ID
for either side and things will be OK. In the SNMPv3 world
there engine IDs must be unique in order to be able to do
engine ID discovery and time sync correctly.

Best regards,
Frank
