Firepass SNMP Problem

We have a Firepass 4300 ver 6.0.3. I want to get the number of current server sessions and the failover status. When I run snmpget to test the access to the data I get the message "FIREPASS-SYSTEM-MIB::fp1000ServerSessions = No Such Instance currently exists at this OID". I do get data back from standard MIBs. This implies the FP is responding to the gets but the FIREPASS-SYSTEM-MIB isn't being supported. The help page on the FP admin console says the FIREPASS-SYSTEM-MIB is supported.

 

Anyone know of any problems with the FP supporting its own MIB?
