Hi Karen,
Based on your packet capture, it appears to be related to the privacy parameters. Please verify the privacy encryption algorithm is set correctly. Spectrum 10.2.1 supports the following encryption algorithms for privacy:
- DES: Data Encryption Standard (DES) is a 64-bit standard that encrypts and decrypts data.
- 3DES: Data Encryption Standard (DES) is a 64-bit standard that encrypts and decrypts data three times.
- AES: Advanced Encryption Standard (AES) is a 128-bit standard, cryptographic algorithm that encrypts and decrypts data.
- AES256: Advanced Encryption Standard (AES 256) is a 256-bit standard, cryptographic algorithm that encrypts and decrypts data.
By default Spectrum uses DES.
I would try modeling the device with the SNMPv3 profile first, however, I think the traps could use a completely different profile than that used to model the device. But typically they should be the same. If you try modeling the device, get a packet capture. If the modeling fails, look for any Report PDU's coming back from the device, they should help determine why the modeling failed.
- usmStatsUnsupportedSecurityLevel (1.3.6.1.6.3.15.1.1.1.0) - This is set when the security level specified is not supported by the agent.
- usmStatsNotInTimeWindows (1.3.6.1.6.3.15.1.1.2.0) - This is set when the engineTime specified is not within the timeWindow of agent.
- usmStatsUnknownUserNames (1.3.6.1.6.3.15.1.1.3.0) - This is set when the user name specified is not present in the agent.
- usmStatsUnknownEngineIDs (1.3.6.1.6.3.15.1.1.4.0) - This is set when the snmpEngineID specified in the request message does not match with that of the agent.
- usmStatsWrongDigests (1.3.6.1.6.3.15.1.1.5.0) - This is set when the password specified is not correct.
- usmStatsDecryptionErrors (1.3.6.1.6.3.15.1.1.6.0) - This is set when the packet is unable to decrypt on the agent side. This error occurs while querying an AuthPriv user.
Hope this is helpful,
Brad
