Q: a client has a network with 60 AP's controlled by a AIR-CT5508-50-K9 (+ L-LIC-CT5508-25A) with a redundant power supply. Can he get full redundancy by purchasing a second controller? If he purchases one, can he bring it into the network? What about the extra license for 25 extra AP's installed on the first controller?
Suppose the client decides to purchase a second one, can he install this second controller as a 'sleeping backup' device in the network, together with the first one or does he have to put it aside waiting until the first goes out of service?
Isn't it better to just purchase an onsite SMARTnet?
Can he get full redundancy by purchasing a second controller?
No, it needs AP license just like the one in production.
If he purchases one, can he bring it into the network?
Yes. WLC can run all day long without AP license on them but it won't be useful to have as backup as APs are not going to join them. However all WLC comes with evaluation license that let you join the APs for limited time.
What about the extra license for 25 extra AP's installed on the first controller?
Get AP license count specifically for the second/redundant controller. Your first WLC seem to have capacity for 75 APs, You need redundant WLC with AP license count similar to the first one i.e, 50 + 25A.

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.

The script should be completely self explanatory.
