not getting any snmp results after snmp get

Has anyone experienced this before?

 

 

snmpget -c public 127.0.0.1 .1.3.6.1.4.1.3375.2.1.1.2.1.43

 

 

F5-BIGIP-SYSTEM-MIB::sysStatTmSleepCycles = No Such Instance currently exists at this OID

 

 

 

I've confirmed that public is the community and has the read-only access for OID .1

 

 

may be I'm doing something wrong?

 

 

This result is from a BIG-IP Version 9.3.1 37.1 Final Edition
