Re: Inter controller seamless roaming(L2), options

Without cluster L2 seamless roaming is not possible?

We don't have MM . We configured on the controller as Master and other 2 controllers are MD1 and MD2.

We could see both MD's are displaying in Master.

Configurations made in Master are successfully pushed to both MD's

Even we didn't see client roams seamlessly.

You might want to try ip mobility, then:  https://www.arubanetworks.com/techdocs/ArubaOS_83_Web_Help/content/arubaframestyles/mobility/ip_mobili.htm

 

I have not personally tried ip mobility  for ArubaOS 8.x, because clustering makes roaming between controllers very easy.  I would say that in the past it has been encouraged to design the network to minimize roaming of clients between controllers, because it makes troubleshooting difficult.

Re: Inter controller seamless roaming(L2), options

Another thing you can do is enable the "FDB Update on Assoc" in the Virtual AP profile to update the cam tables when a client associates to see if that makes a difference:  https://www.arubanetworks.com/techdocs/ArubaOS_83_Web_Help/content/arubaframestyles/virtualaps/conf_vap_prof.htm?Highlight=fdb

 

Can both of your explain what tests you are running during roaming between controllers that do not work?

Re: Inter controller seamless roaming(L2), options

We have very basic setup to validate L2 seamless roaming.

One Master and 2 MD's.Both MD's jobed with Master.The configuration we created in Master is refleclecting in both MD's.

We have a profile with FT-802.1x configuration.

Each MD has one AP joined.

We have connected Client to AP1 which is with MD1. Our client slowly roaming form AP1 to AP2(which is on MD2).

During roam we are sending reassoc request,But AP2 is not honoring reassoc reuest.So the client is going for Full Authentication ,which is not correct.

We are expecting as per configured Fast roam (OKC or PMKID or FT)

As you mentioned clusetring supports in MM .Does the configuration of cluster is s/w based or specific hardware required to use cluster.
