The Brocade switches our network is in love with didn't have entries in the SNMP System OID classification table. On initial discovery the "Name of the Model" field was being populated with the value from that is grabbed by the "SNMP - Classify" SNMP Probe from mgmt.mib-2.entityMIB.entityMIBObjects.entityPhysical.entPhysicalTable.entPhysicalModelName
So initally I looked at the input Queueu for ths SNMP classify probe found the SnmpObjectID and then registered the appropriate information into the SNMP System OID Classification table.
The problem is that about 25% of the switches apparently do not provide SnmpObjectID in the SNMP Classify probe.
My question is, how can I set the SNMP Classifier to be "Standard Network Switch" which then dumps it into the cmdb_ci_ip_switch table and set the Manufacturer and Model information based on mgmt.mib-2.entityMIB.entityMIBObjects.entityPhysical.entPhysicalTable.entPhysicalModelName. For example if entPhysicalModelName="40-1000925-05" then I know this is a Standard Network Switch, and, that the Manufacturer is Brocade and Model is "VDX 5740"

I wrote a post about something similar to this once

The SNMP Probe Parameters allows for a few qualifier operators that may be helpful to you
