Receiving SNMPv3 Notifications
SNMPv3 uses a different notification model than previous SNMP versions. To receive SNMPv3 notifications, you need a proper authentication profile since they have to be decoded with a password and given encryption settings.
Because SNMPv3 allows authentication and encryption of receiving traps, you need to define the SNMPv3 Notification profile for them. Otherwise, the program won't be able to decode anything.
Unlike in v1 and v2 profiles, profiles for v3 are global, which means you can define them via NetCrunch Monitoring SNMP Communities and Passwords..., and you do not have to assign them to nodes.
NetCrunch supports the following authentication and encryption protocols:
Authentication Types
- HMAC-MD5-96
- HMAC-SHA-96
- HMAC-192-SHA-256
- HMAC-384-SHA-512
Encryption
- DES
- 3DES
- AES 128
- AES 192
- AES 256
