My customer has a college campus, basically one location with 800+ AP's, would it be possible to use the Flex 7500 WLC to controller all the AP's?
Could I use a 2nd 7500 WLC as a redundant controller?
Only if the AP's are in H-REAP mode.
Are you just trying to have N+N (or N+1) Capacity?
What about 3 5508-500s? WiSM2s?
Possibly talk to account team about future plans for any WLC (in addition to 7500) to have more than 500 AP capacity (assuming you'd rather stick to 1 single device with 1 single backup)
I know I can use the 5500/WISM but wanted to clarify the capabities of the 7500. What I missed, was that the AP's are in HREAP mode all the time.
