Opened: Aug 07, 2019

Severity: 3-Major

Symptoms

The virtual server for an LTM redundant peer is continually updated with its IP or Port changing back and forth between two values, leading to perpetual GTM configuration syncs.

Impact

The virtual server is flapping status between "blue" and 'green', and its destination IP:port is changing between a correct value and an incorrect one. Traffic will be impacted.

Conditions

--The destination IP:port of the virtual server on the LTM is not in sync between the LTM devices in the device-group. --Another way to trigger this is in a LTM device group by use of non-floating virtual server addresses with same virtual IP name.

Workaround

--Perform a configsync on the LTM device-group that owns the virtual server. --Do not use the same Virtual Server name in Device Group if members of the device group have different destination IP for the same virtual server name. For the existing configuration: edit bigip.conf, modify virtual server name, and reload the configuration.
