What do the new flow control settings do? Obey, Generate, Both.

Also, how exactly does the new flow control storm control work?

Obey = The port will obey Rx Pause Frames but not generate Tx Pause Frames
Generate = The port will not obey Rx Pause Frames but will generate Tx Pause Frames
Both = Obey Rx Pause Frame and Generate Tx Pause Frames

These are pretty much standard settings for Flow Control found on most switches

Pause Frame Storm Protection will trip and disable Flow Control on a port and log the event and send an SMTP message if it receives 10,000 more Rx Pause Frame than Tx Packet per second for 5 consecutive seconds.

Can you put that in english? Like as in should I use it when the switch is connected to a Metrolinq 60ghz backhaul.....or rather, which one should I use.

What would be the router ?

Here a diagram of how it work. Hope it's help.

Thanks mike, that helps. The router is edgemax.

Unless I missed something, Edgerouter standard line don't support flow control since the Cavium ASIC don't support it.

Edgerouter X line support it but it's a single ether behind a managed switch. A pause frame would block traffic on all edgerouter X ports just like in the section 4 of the image.

Which is why I never have a backhaul radio share an interface driving local radios.

Instead I use the switch as a midspan injector and each backhaul has its own port in the tower router.

Then I use a STATIC LAG to supply all switch ports to each AP or local PTP for a high end customer.

This way Pause frames from local radios are spread across 2 interfaces and never affect traffic that is transient through the tower to the next tower.
