Hi, A customer of mine has a wireless network based on the following: WLC 5760, CAP 3702, Cat 3850. They wish to implement dual controllers at the central location and Cisco 3850 at the branch locations. If the cat 3850 are working in the MC mode, what would happen when there is a controller failure at the central location (assume both fail) or the link between the central location and branch drops?
So would it be a good idea to include a single controller at the HO as well? Would the same setup work with a 5508 controller as well? Because there's another customer who is considering something similar.
It depends on the HQ user requirement. If they want wireless to be available all the time (ie HA ) then better to have two WLCs & use them as HA pair. It is always better to have some sort of redundancy,so two WLC at HQ is advisable (even if it use as N+1 setup).
Since Branch & HQ WLC acting as dedicated controllers there is no dependency on each other. So if you want you can bring 5508 instead of a 5760 at HQ.
Only requirement for these two WLCs to talk to each other is Guest Tunneling (both 5760 or 5508 can act as Guest Anchor for a 3850)
Transferring Crash file from standby:
Login to the Active WLC in HA.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
