Hello All,
We are upgrading our switches to SNMP v3.
What do we need to consider (in relation to comms with DM) when we upgrade the switches please?
What authentication/encryption does v9.5 support please?
Do we need to make any changes on the DMAs to support SNMPv3 please?
Rgds,
Mark
Indeed, and not only on the DMA. On the side of the device it also requires CPU resources. There are situations where the polling of the device needed to be slowed down due to the CPU usage, so you might want to take a look at the resource usage of the device itself (if it’s possible to access that data of course) to see the difference between SNMPv2 and SNMPv3.
Hi Mark,
Authentication algorithm: In DataMiner 9.5 either HMAC-SHA or HMAC-MD5.
Encryption algorithm: In DataMiner 9.5, either DES or AES128.

Small side note: SNMP v3 communication uses encryption, and to encrypt and decrypt the messages extra CPU cycles are needed. If you have a lot of elements you switch to SNMP v3, it is possible you will notice an increase of CPU usage on the DMA…
