Known Affected Versions:
11.5.1, 11.5.1 HF1, 11.5.1 HF10, 11.5.1 HF11, 11.5.1 HF2, 11.5.1 HF3, 11.5.1 HF4, 11.5.1 HF5, 11.5.1 HF6, 11.5.1 HF7, 11.5.1 HF8, 11.5.1 HF9, 11.5.10, 11.5.2, 11.5.2 HF1, 11.5.3, 11.5.3 HF1, 11.5.3 HF2, 11.5.4, 11.5.4 HF1

Fixed In:
11.5.4 HF2

Opened: Sep 23, 2015
Severity: 3-Major


An SNMP query response for ipAdEntAddr would sometimes return floating IPs rather than local IPs. This was due to the supporting software returning the first found IP address for a given vlan.


No impact to BIG-IP services, but the returned information to the SNMP query is sometimes incorrect.


Problem started after upgrading to v11.5.1 Eng-HF7, from v10.2.4. The same problem can happen on freshly installed 11.5.x as well.
