PS4100 and SNMP v3

Hi,

I'm trying to use my SNMP monitoring solution (nagios) to poll my PS4100 (v7.0.9) and retrieve various metrics.

I have it working with v2 but I need to use v3. Please can someone advise on what the following should be for communicating via SNMP v3:

Auth Protocol - MD5 or SHA1

Priv-Protocol - AES or DES

Does anyone have this working who could share their settings?

Thanks,

Steve
