Hello,

I have a new EAP670v1 running 1.0.3.  This is my first Omada configuration.

I have a very simple setup, 2 SSIDs, one on 2.4 and the other on 5 Ghz.  Both SSIDs are assigned VLAN100.  The mgmt vlan is 600, but is sent as a native, so untagged.

After the AP starts taking on clients, it starts sending data on both VLAN100 and 600 intermittently, so nothing is able to communicate with the network correctly.  Output from Cisco switch (I've highlighted a duplicate as an example):

switch1#show mac address-table interface gigabitEthernet 1/0/8

 600    a45e.60be.5231    DYNAMIC     Gi1/0/8
 600    ec39.8100.0064    DYNAMIC     Gi1/0/8

I have tried moving the management VLAN to a tagged VLAN, but the packed still arrive as duplicates, on VLAN1 instead.

The data is being sent in a load balanced method, oddly.  If I block every other VLAN, traffic is dropped from the client perspective, but I suspect the EAP is still trying and the switch is just dropping the traffic.

Anyone have any troublehsooting ideas?  I am out of ideas.
