I'm not sure I understand your question, but his is how ethernet fallback works
Information About FlexConnect Ethernet Fallback
You can configure an AP to shut down its radio when the Ethernet link is not operational. When the Ethernet link comes back to operational state, you can configure the AP to set its radio back to operational state. This feature is independent of the AP being in connected or standalone mode. When the radios are shut down, the AP does not broadcast the WLANs, and therefore, the clients cannot connect to the AP, either through first association or through roaming.
To prevent radios from flapping when there is flapping of the Ethernet interface, a delay timer, which you can configure, is provided.
But of course this only works as described if the access point has an alternate power source than PoE from the same ethernet connection.
If this is an access point with an active ethernet connection, the radio will stay operational and clients stay connected. on [apply].
does this answer your question?
