what is different between AP ethernet port mode backhual and bridge-802.1q?

I config an AP230 with cli, when choose the eth0 mode bridge-802.1q, the ssid isn't broadcasting, after change it the backhual, the ssid appear again, so what is different between backhual and bridge-802.1q

here is the help message from AP cli:

    backhaul        Set the interface in backhaul mode, making it a
                    VLAN-aware layer 2 interface through which the default
                    MAC route for traffic to and from the main LAN passes
    bridge-802.1q   Set the interface in bridge-802.1Q mode, making it a
                    VLAN-aware layer 2 interface to enable the bridging of
                    traffic between 802.1Q VLAN-capable devices in a wired
                    LAN segment and the wireless LAN (Note: The default MAC
                    route is never on an interface in this mode.)

I could confirm that backhual is working as trunk port too, from the help message, the only different is just the default mac route is on or off? so what is mac route again?

Hello,

the type “backhaul” on CLI is called “Uplink Port”. You need this port type for ports connecting to the XIQ.

Only with the “Uplink Port” the connection to the cloud is possible. The other port types are for ports connected to other subsequent switches or devices.

May I ask why?

Hello I am not sure what the why in your question refers to.

For a network device it must be clear on which interface the default gateway is located, I assume this is determined by the “Uplink port”.

well, I mean why the aerohive ap was design to broadcast ssid before checking if the ethernet could reach the subnet’s default gateway. this principle is different from the other brand wifi solution. when I troubleshoot, it may disrupt the ethernet connection.

anyway, what exactly step take action before an aerohive ap is going to broadcast ssid? Is that any way to check the requirement on cli?

Hello,

I have similar problems related to this. The description for this 3 modes are pretty unclear.

I had backhaul mode selected with a “channel-group mode on” in the networking side. After upgrading from 8 to 10 firmware, the second port went down. I think something changed internally.

Extreme, we need a clear documentation for this aggregate modes. I mean, this is a topic well-known at switching side. You should rename this as LACP, active-passive or whatever your APs are doing.

Thanks.
