roaming b/w building blocks

Hi,

 

Building Blocks are saparated by two virtual AP's with same SSID name (different vlan), but occasuionally  vlan sticks to same ip even if moved across building, but connection shows to the respective building AP the user is in, but ip doesnt match to the ssid vlan, then disconnect reconnect is required, any help?

 

Thanks

You have 2 choices:

 

- Make both buildings the same virtual AP

- Enable VLAN mobility in the Virtual AP profile; that will allow users coming from a different virtual AP to retain their VLAN when roaming to an access point in a different virtual AP on the same controller.

we dont want to retain the ip, we want to change the ip according to the buliding, our experience is that in occassionally ip retains.

Not possible unless the client sees that the link goes down.  You cannot roam between buildings on the same SSID and make the client change ip addresses, period.

 

Network administrators should design their networks so that users who roam maintain the same ip address for seamless performance.  There is no advantage to changing ip addresses within the same network.

we do this to separate AppleTV's, we had hard time with AirGroup.

If you want users to connect to Apple TVs in the same building, make the VAP in the second building have the same VLAN, but a different role that blocks bonjour traffic from subnets in other buildings.  With that being said, the client will still maintain a "memory" of Apple TVs that it saw before, so it will not be perfect.

we use /24 subnet, otherwise we end up a big broadcast subnet.

I am not sure how you would do this without airgroup.

Re: roaming b/w building blocks

Our issue is with Airgroup, can I ask your advise related to this,

 

Should we enable igmp in vlan ip interface in ARUBA controller for AppleTv to work efficiently ?, also snooping to be checked or not.

 

Thanks
