Hello,
I have got the solution to this problem.
The problem was that for configuring SNMPv3 traps, i was adding below in the
snmpd.conf file:
trapsess -u <username> -l <security level> <host IP>
It was working well for MD5, but for SHA auth and priv (both DES & AES) it was
sending a trap , but it was getting error which receiving at the manager saying
that authentication (for SHA) or decryption (for MD5 + DES/AES) failure.
If we are configuring the 'trapsess' with the engine-id then it is working well
for all these auth (MD5,SHA) and priv (DES, AES), as below:
trapsess -e <engine-id> -u <username> -l <security level> <host IP>
thanks and regards
S Sarath

Subject: not able to receive SNMPv3 traps for SHA, and priv users
Hello,
I am using net-snmp version 5.4.2.1. I am able to send traps for SNMPv3 users
for authentication with MD5 and receive them properly by the manager software.
But while sending traps with authentication SHA or using SNMPv3 users with
encryption, I am not able to receive them at the manager.
I have tried to capture the traffic from my device, and I could see these traps
(SHA and encrypted) being sent from the device, but these are not getting
received by the manager software.
I have tried with couple of management software, like net-snmp's snmptrapd, and
ManageEngine MibBrowser free tool 5.0. In both of them I only able to receive
MD5 user's traps only.
Though SNMPv2 traps are getting properly received.
Also the user config, are done in same way for both MD5 user and SHA user on
the snmptrapd.conf file.
Please advise how to solve the problem.
thanks and regards
S Sarath
