What would be the topology if multiple VNS exist on same interface of identifi controller

[Saiprasad_Rao_R]

What would be the topology if multiple VNS exist on same interface of identifi controller, is it same as multiple vlans passing on trunk port ?

Controller will be having one L3 ipaddress on that interface ( for GUI access from network)

I want to switch traffic locally at AP......

Hi Saiprasad,

Its recommended to use separate Admin interface for GUI access from network.
You may find default topology with B@AP configuration for switching traffic locally at AP. You can make use of that topology.
Extreme doesn't use the term "trunk". Create one topology for each VLAN IDs and assign it to esa0/1/2 or 3. Assume topology as a VLAN with an egress port. While creating B@AP topology assigning controller's physical interface is not needed as VLAN are going to be at AP.

For more info about topologies, Pl read IdentiFi wireless user guide, Chapter 5. Configuring topologies. Link here: https://extranet.extremenetworks.com/downloads/Pages/dms.ashx?download=c2513a5a-1186-4e25-ae97-dc9e1...

Assuming availability link is up yes, if you have fast failover (FF) enabled, you can see in the availability reports that the AP would have 2 tunnels, 1 active to the home controller and 1 backup to the foreign controller.

ok! understood

with your method of manual approval, will the ap's failover to the other controller if one of the controller goes down.....

But what if there are 2 controllers in availability.how will the above dhcp scope part work.

With availability enabled and the default setting of approve all AP's set, then the AP would register on the controller defined, with manual approval enabled, you would see the AP on both controllers and could approve it on your chosen controller (this mode is my preferred configuration as it gives maximum control.) Additionally, in dhcp options you can specify 2 controllers IP's.

Does "but it's still best practice to define dynamic discovery" mean not to define controller IP in dhcp scope....

No, it means you should define the controller IP(s) in the scope.

Is the above procedure (dhcp part) applicable even when both ap and controller are in same vlan or not necessary.......

That's correct.

Please see page 111 of the current Wireless user guide for an in depth explanation of the AP discovery process (requires Extreme extranet login) https://extranet.extremenetworks.com/downloads/Pages/WirelessControllers.aspx
