Several SNMP OIDs need to be added to provide the total number of port block allocations (PBAs) and the percentage of PBAs that are available.


Need to manually calculate the values.


Attempting to retrieve total number of PBAs and percentage of PBAs that are available.


Make manual calculations from the current stats or configuration.

Fix Information

-- Can now directly gather the total number of PBA and percentage of ports available. There are new SNMP OIDs from which to pull this data directly. Although there is way to get this information from the current stats or configuration by making some calculations, the SNMP OIDs enables pulling these values directly.

Behavior Change

The following new MIBs are now available: F5-BIGIP-LOCAL-MIB::ltmLsnPoolStatTotalPortBlocks F5-BIGIP-LOCAL-MIB::ltmLsnPoolStatPercentFreePortBlocksSnmp F5-BIGIP-LOCAL-MIB::ltmFwNatDynamicPoolStatPbaTotalPortBlocks F5-BIGIP-LOCAL-MIB::ltmFwNatDynamicPoolStatPbaPercentFreePortBlocksSnmp
