Hi Reza,

Thank you for the questions.
If you have an existing controller e.g. 5508 with 50 base licenses and 100 adder, you can convert it to HA today. If you choose to migrate it back to being a primary controller, the licenses will be remembered and reverted back on the box.

The HA SKU cannot be used as an anchor. You can however have the HA SKU be a standby to the anchor to increase resiliency.

Best Regards,
Jeevan

Hi
Can the HA box have AP licences installed on it. Can’t think of a use case for it but just wondering.

Also can the HA box be used as an Anchor WLC.
I am thinking of having the standby HA installed in DMZ and use it for both Anchor and standby.
Regards

In 7.3 release with 5508, Flex7500 and 8500 the two controllers need to be physically adjacent to each other and the redundancy ports connected with ethernet cable. The two WiSM2 blades can be in the same chassis or another chassis with VSS technology.

Hi Jeevan
Is this achievable/supported across a L3 boundary / Campus LAN?

If RP fails, there won’t be any more config or client key cache sync between the active and standby controller.
Also, since RP fails the standalone controller will go into maintenance mode where it won’t communicate with any other controller on the network.

BTW good news to all, the 7.3 code is already posted

HA PIDs will be order able in the next few weeks

Hi jeevan ,
Thanks for the info ..
Just tell me one thing, wot will happen if redundancy port failed in any of the controller which means whether the key cache will sync only after the fail-over or it sync at regular interval

Sorry JW,

We do not post pricing information in advance of the release.
My request is to reach out to your local Cisco representative on the pricing of the Standby Controller.

Regards,
Jeevan

Jeevan,
Thanks for the info – this HA pricing feature is long awaited. Glad to see it’s here.
You mentioned being able to order in a few weeks – do you NTE pricing for the Standby controller (AIR-CT5508-HA-K9)?
