Two WLC 5508 Anchor High Availability

[Jorge Plata Vivanco]

Hello.

It's possible use 2 WLC 5508 en ANCHOR MODE in a Active-Active scenario?.

For example, if one WLC get down of service, the other one keep provide service to the anchor clients?.

In this moment we have just one WLC 5508 in Anchor Mode. What i need to configure a ANCHOR high Availability.

Thanks A lot!!!

We average about 15,000 guest on our network a day. We have them hanging off two 5520s. We just upgrade from 5508 because of the 7,000 client limitation. The 5520 support 20,000 each.

We have 30 or so foreign controllers. 15 / 15 split to each anchor. We did this because we found troubleshooting round robin was problematic. Also its rare we lose an anchor and if we did we would have to manually anchor the WLAN to the new anchor controller. A process that takes just a minute to do. Also if you have anchors in the same mobility group especially with thousands of clients thats a LOT of mobility message updates so we change the mobility names two. 

That just my 2 cents ..

1.Is it good practice to keep same mobility group name for both anchors? 

note:-anchors configured with priority01 and priority-3 on foreign controllers side.

2.and  by keeping same name, does both share the client information?

3. ISE based Guest auth(captive portal), does really user need to login back when primary anchor(priority-1) fail and user moved to sec anchor(priority-2)?
