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.
None.
