Hello,
I have two 5508 WLC's setup to run about 200 AP's as the moment. This is a hospital with patient care now running over wireless. I am looking for the best scenario to minimize down time. Currently both controllers are in the same mobility group and I will be setting the primary / secondary controller in the High Availability tab for each AP. Most setting are all default still.
My question:
Would it better to setup the primary/secondary from the global configuration?
Can I leave them in the same mobility group if I use the global configuration?
My only problem so far is having AP's on different controllers caused some response delay as clients move from one controller to the other. I need to find the best possible response time with the lowest possible fail-over time. Any recommondeations or links to a good article on this subject?
Thanks,
Todd

What you would want to do is set the Primay/Secondary on a Per AP basis, the global configuration are technically 4th and 5th in the WLC failover process.
You could do this via the CLI, or NCS/WCS if you have it.
Yes keeping them in the same mobility group would be preferred.
As for the roaming, are the WLC using the same layer 2 vlan/subnets, or are they using different ones?
HTH,

Both WLC's are in the same subnet. I had one AP out of six in a patient area switch over to the secondary and there was a strange delay when clients moved in and out of that AP area. I figured it was relating to a different management IP or something. Of course that was before I read up that both WLC should have the same Virtual IP...

I have read some instructions for changing the timeout’s and polling. Does anyone recommend this or are the defaults acceptable? I want minimal downtime but I also need stability. Anyone have horror stories they want to share or some best practice advice?

If you need AP SSO then use the new HA from 7.3 code.
