The SFP interfaces do not come up, or they flap up and down repeatedly on BIG-IP 2000/4000 on boot up when both SFP interfaces are populated. When interface flaps state changes such as those below are logged in ltm log: info pfmand[PID]: 01660009:6: Link: 2.1 is UP info pfmand[PID]: 01660009:6: Link: 2.1 is DOWN
Traffic cannot be sent/received from these interfaces.
Both SFP interfaces, 2.1 and 2.2, on BIG-IP 2000/4000 are populated. This is typically observed on boot up after an upgrade to an affected version. And this may occur during normal reboot
Disconnect and reconnect the cable.
The interfaces now come up successfully. Occasional link bounce may be seen on reboot.
