High traffic loss observed by the clients associated with LWAP in Flex mode once CAPWAP tunnel re-established. WGB and clients behind it report a partial traffic loss, when the CAPWAP tunnel between the WLC and Flex AP is reestablished after going down under two circumstances -- Distribution switch reload or link between WLC and access switch to which AP is connected goes down. These traffic drops are consistent.

This symptom is observed especially for the clients associated with LWAP running in Flex mode with unified setup
