How to setup controller redundancy (Aruba 620 to Aruba 620)

Do I need to have a same Firmware Image? What Licenses do I need to have? What Firmware Image that will support this redundancy? How will be the Configuration? does the 2 Controllers need to be in the same subnet?

Take a look at these:


Chapter 3: http://community.arubanetworks.com/aruba/attachments/aruba/Aruba-VRDs/22/1/Campus%20Redundancy%20Models.pdf





Master-Standby requires same subnet for VRRP, Master-local does not. Controllers must be running the same firmware.

Aruba supports two different types of redundancy,

1. Master-Standby : this will run on VRRP hence bot the controllers need to be in the same subnet (VLAN) but it doesn't require any license.

2. Master-Local : This is a distributed model with fail over redundancy,generally master will handle Configuration, ARM IDS etc and APs will be terminated on Local. Here both the controllers are assumed to be deployed different locations (Master - Head office, Local- Branch office) hence they need not be in the same subnet and does not require any license.


For both it required to have same image and licenses ( AP, PEF, RFP etc..)


Hope you got some more clarity, please feel free for any further clarity on this.
