Symptoms

SFP interfaces start flapping on 2xxx/4xxx platforms, and it takes some time to go into an up/running state.

Impact

Interfaces are unusable until it stops flapping and goes into an up/running state.

Conditions

Happens on the following platforms using the SFP interface: 2000s/2200v 4000s/4200v

Workaround

There is no known mitigation except to wait for the interface to go into the up/running state.

Fix Information

Enough time is provided for the SFP interface to complete initialization and go into the up/running state.
