SNMP ltmPoolMemberMonitorState - OID Truncation Rules

Hi,

is anyone aware of the, seemingly "new" OID truncation scheme for long oids? We have just upgraded from 11.4 to 12.1 and our snmp queries are not predictable anymore.

The once working query is (for example):

F5-BIGIP-LOCAL-MIB::ltmPoolMemberMonitorState."/Common/Pool_re_dac_ted_ultralong_pool_name_xyzxyzxyzxyzxyzxyzxyzxyzxyzxyzxyzxyzxyzxyz"."/Common/MEMBER1".443

Now we need to query for:

F5-BIGIP-LOCAL-MIB::ltmPoolMemberMonitorState."/Common/Pool_re_dac_ted_ultralong_pool_name_xyzxyzxyzxyzxyzxyzxyzxyzxyzxyzxyzx9d3d7c89"."/Common/MEMBER2".443

Is anyone aware, how the 9d3d7c89 is calculated, so I can update our scripts? Unfortunately we are not able to change the monitoring to iControl/ssh/... and the usage of snmp is obligatory for us by now.

Thanks in advance and regards,

\seb
