3850 controller HA

[hans.velez]

Hi all,
I was wondering if i need to had a HA architecture for the wireless service and i want to buy the new 3850, i had to buy two 3850 in order to have HA in one floor?

The APs attached to a 3850 in one floor can have a second controller reaching this across the network?

As per my knowledge 3850 not supported the HA.

You stack them both together to form a single logical unit.  However, for example your APs are in Switch 1 and Switch 1 fails, then someone needs to manually move the APs directly connected to Switch 1 to be directly connected to Switch 2.

Hi Hans,

Refer this Q&A doc for CA deployment

http://www.cisco.com/en/US/prod/collateral/wireless/ps6302/ps8322/ps12598/qa_c67-726507.html

Q. What type of high availability is available with the Cisco 5760 WLC?
A. The Cisco 5760 WLC in centralized deployment mode (also known as local mode) supports N+1 resiliency. It also supports multiple link aggregation (LAG) to protect against link failures while maintaining throughput.

Q. What high availability is available with the Cisco Catalyst 3850?

A. The Cisco Catalyst 3850 supports subsecond failover through stacking. For wireless, access point Stateful Switch Over (SSO) is supported.

Page 58-71 in the below presentation talks about HA on this CA platforms. Please go through it.
