[snmp] Recieved Engine ID is not correct

[tausifk]

All,

I am getting an exception - "Received engine Id ('80001F88800C330000999E0746') is not correct"

The scenario is, I run my snmp manager (Westhawk API) and fetched the snmpv3 information from an Net-SNMP agent running on a perticular device. Now my manager is still up and running and I re-install the Net-SNMP agent and configure the same user with same credentials as before. Now I again try to do snmpv3 ping and get this exception:

=================================================================================
snmpgetV3.start() PduException: Received engine Id ('80001F88800C330000999E0746') is not correct. amIAuthoritative == false

I understand that the re-installation of Net-SNMP agent re-generate the engine-id and my snmp manager chached the engine-ID before when I did snmpv3 ping and there is a mis-match.

Please do let me know is there any bug with SNMP-Westhawk API or it is a wrong behaviour of Net-SNMP agent which is re-generating the different enging-id?

I am using Westhawk SNMP 5.1 version for my snmp Manager.

Thanks in advance
