Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP AFM(all modules)

Known Affected Versions:
15.0.0, 15.0.1,,,,, 15.1.0,,,,,, 15.1.1, 15.1.2,, 16.0.0,, 16.0.1,,

Fixed In:
16.1.0, 15.1.3

Opened: Aug 18, 2020

Severity: 3-Major


The 'total port blocks' value, which can be found in PBA 'tmctl' tables, 'tmsh show', and SNMP, is limited to 64 bits of range. The upper 64 bits of the value are not taken into account.


Incorrect statistics.


This always occurs, but affects only systems whose configuration makes the 'total port blocks' value exceed 64 bits of range.


None. Note: For those who really need this value, it is still possible to manually calculate it, but that is not a true workaround.
