AP with redundant Ethernet connection

How does AP125 prevent loop if both Ethernet port are connected? Do I need to enable spanning tree on the access switch connecting the APs?

Re: AP with redundant Ethernet connection

By default, if one ethernet interface is up, the other one is disabled in software.

Re: AP with redundant Ethernet connection

So I would expect one port to be up while the other port to be down, showing not connected from my switch end? Thanks

Re: AP with redundant Ethernet connection

So,

 

The link for both ports come up, but the AP chooses one to send and receive traffic.  If the AP is poe and the active port is disabled, the AP will lose power and reboot.

 

You should see this on the console on bootup"

 

Getting an IP address...
bonding: bond0: link status definitely up for interface eth0.
bonding: bond0: link status definitely up for interface eth1.
bonding: bond0: making interface eth0 the new active one.
