controller assisted mobility will help ?

Aviv_Kedem — Fri, 21 Jul 2017 23:23:00 GMT

We have in some warehouse, is divided with 2 ip segments.We have here only unmanaged switches, with 20 pices of AP6532 and 20-25 wireless clients.
We need to make wireless clients to roam between 2 ip segments.
If we configure VC with controller assisted mobility + layer3 adoption, it will make the roaming work?
Or just only way is buy NX/VX for tunneling WLAN traffic to controller ?
Thanks

Hello Aviv,

In a VC environment, if all APs are in the same broadcast domain (layer 2) roaming will be seamless.

As of today, If some APs are behind a routed switch (layer 3 adoption) then roaming between APs on either side of the switch will not be seamless unless a fully fledged controller (NX/VX) is used.

Regards,

Chris

Hi Aviv,

To use controller assisted mobility you will need to tunnel traffic back to the controller and the Virtual controller does not support tunneling.
You will need to ensure you purchase a controller that supports tunneled traffic if you want to use controller assisted mobility.

Please see related article below.

Additional note:
The VX does not support tunneling

Kind Regards

Wow,

The VX does not support tunneling

Thanks

I was sure tunneling with VX is working but not recommended since is not have a dataplane .
Are you sure?

Yes,
VX does not support tunneling.
Please be advised that even if it is working in your environment, it is not a supported configuration on the VX platform.
As you noted it does not have a dataplane.

So if I understanding right, if we had 2 vlans on ge1 of AP's, wlan with vlan pool, layer3 adoption with VC - assisted mobility was work with local bridging?
Thanks

Get a RFS4010, is the cheapest solution.
If you use just a VC you can configure a L2TPv3 tunnel for L3 mobility. But you need an endpoint for this.
Maybe you have a firewall that can run as L2TPv3 endpoint.

Just got the official approving that VX9000 does supports tunneling and there is support for the configuration.
But it is important be considered about amount of traffic will be forwarded in case of tunneling wireless clients data.

Thanks to all

Hi Aviv,

I am glad this might work for you within your environment.
But be aware as stated prior that deployment would not supported by the support desk if you run into issues pertaining to those tunneled vlans.
Forwarding/Tunneling vlans on platforms that do not have a dedicated dataplane is not recommended.
