SFP interfaces start flapping immediately after booting up 2xxx/4xxx platforms, and it takes some time to goes into an up/running state.
Interface are unusable until it stops flapping and goes into an up/running state.
Happens on the following platforms with BIG-IP 15.0.x using the SFP interface: 2000s/2200v 4000s/4400v
There is no known mitigation except to wait for the interface to go into the up/running state.
Enough time is provided for the SFP interface to complete initialization and go into the up/running state.
