Opened: Aug 07, 2019
Severity: 3-Major

Symptoms

The virtual server for an LTM redundant peer is continually updated with its IP/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.

Workaround

Perform a configsync on the LTM device-group that owns the virtual server.

Fix Information

None
