Acme Packet 4600 Monitoring

Need to monitor our Oracle Acme Packet 4600 with SNMP V3.  However, it is not working as SHA or SHA1 from Solarwinds is not recognized by the appliance. The Appliance is limited to 256 & 512 on the SHA.  Has anyone set this up before or created a custom Poll for this since Solarwinds does SHA1 by default ?
