The Management interface flaps after rebooting the device, which causes a momentary active-active condition in a high availability (HA) configuration.
Devices go active-active for a few seconds and then resume normal operation.
This can occur after rebooting the active or standby device in an HA configuration.
You may be able to work around this by changing the management port speed to 100/Fixed Duplex. For more information on changing the interface, see K14107: Configuring the media speed and duplex settings for network interfaces (11.x - 13.x), available at https://support.f5.com/csp/article/K14107.
