Is there anyway for both ports on a ap 320 to work at the same time? And if you can how do you do it?

Go Monitor -> Aerohive APs -> -> Modify.

Under "Optional Settings" expand "Interface and Network Settings". From here you can link aggregate the ports (if your switch supports it) or assign specific VLANs to specific interfaces (ports).

To link aggregate the interfaces click on the "Ethernet Setup" drop down menu and select "Aggregate Eth0 and Eth1".

To assign specific VLANs to specific interfaces click on the "Ethernet Setup" drop down menu and select "Use both Eth0 and Eth1". Expand the "Advanced Ethernet Settings" and you will see where you can assign the native and allowed VLAN for each interface.

That should be:

Go Monitor -> Aerohive APs -> [Select an AP] -> Modify.

Additionally, you can also use the second ethernet port as an access port and bridge something (cash register, video camera, etc...) back to the wired network. It's a totally different use case than what you asked about, but illustrates how flexible the port configuration is.

So you are saying you can bridge with it to. So if I want to hook a computer to the other port on the access point I could and it would get a IP address and work as if it was a regular drop? And how would you going about settings it up? How would it affect the ap?

And for the link aggregate the switch would have to have LACP right?

Yes, can can setup the second ethernet port to be an access port, and have the AP bridge ethernet from it to the uplink port.

To enable that you need to modify the AP's config
scroll down to optional settings
set eth1 operation mode to "Bridge -Access"
Expand Advanced Bridge Configuration
Select a user profile that has the authorization/vlan you want.
Then push a config update.

The main impact is that all devices connecting through the AP will share the same bandwidth (CPU forwarding rate and uplink bandwidth), so you will have a higher oversubscription rate. I really don't think you'd even notice it in normal usage - it's one of those things you could prove with a benchmark test but never actually feel in real life.

Yes, you would have to had some sort of link aggregation setup on the switch it was connected to. LACP or otherwise...

Tash, thanks for this reply.  I have done these steps on an AP370, assigned a user profile that works for all wireless clients (LDAP AD integrated, but MacOS gets on just fine) and cannot grab an IP off of eth1.

I have pushed the update to the AP and even updated and rebooted for good measure.

Any ideas?

(dated thread....but....perhaps useful for someone else)

If the AP370 is like the AP230 we use --- you need to use a 802.11at power source to enable the second port.

In our case, we just used the too expensive, but know it will work 30w AH Injector to answer the issue.... AH-ACC-INJ-30W-US

Apparently, when using 802.11af, there's just not enough current to support both ports.
The 2nd port will show up briefly during power up of the AP, but will be shutdown but the AP's software rather quickly.

Perhaps the same applies to the AP370...

If you are deploying AP370 access points you are most likely looking deploying in a "difficult" environment and need the additional power from 802.3at.   If you just need coverage in an administration type environment the AP230, which is 802.3af, is considerably cheaper and will easily do the job.  In these administration style environments it is unlikely that you need to use the second Ethernet port.  If you do, just use an 802.3at power injector for the AP230 where two Ethernet ports are required.  The remaining AP230 access points can continue to use the 802.3af power from the switch.
