Wireless Access

We have two data centers with Aruba 7220 installed in each DC in Master/Local setup. Plan is to use this set up for our telecommuters with RAP3s. Can I use load balancer (F5 GTM) to load balance RAPs traffic to these controllers?

So you have 1x 7220 as MASTER in DC1 and 1x 7220 as LOCAL in DC2?

OR do you have 2x 7220 as MASTER/LOCAL in DC1 and DC2 (SUM: 4x7220)?

Normally you won't terminate a RAP on a MASTER, but you can do that if you want.

I would recommend the loadbalancing on this way:

Reserve two public IPs for the Controllers.

Create two AP-Groups.

AP-Group-1, LMS-IP: DC1, Backup-LMS-IP: DC2

AP-Group-2. LMS-IP: DC2, Backup-LMS-IP: DC1

Now you have to provision the RAPs in the different groups and you load balance them "manual".

But you can do that with the F5, too.

- Setup your controllers with two public ip addresses.

- Setup a-record on your public DNS server that has those two public ip addresses (e.g. rap.domain.com)

- Setup your DNS server to round-robin (https://en.wikipedia.org/wiki/Round-robin_DNS) so that it delivers alternating ip addresses when a device requests that a-record.

- Provision your RAPs to point to that public dns record (rap.domain.com).

- Your RAPs will obtain alternating ip addresses for the controller and load-balance

Thank you!!

Is there a way to overwrite VLAN IDs that are being replicated from Master to Local for AP group?

Thank you!
