I have a very basic question about WAAS.. I would like to know in case that I have a main office and five branch offices, and I would like to add WAAS modules only to two branches; in such a case, should I install another WAAS module or appliance in the main office? also, I would like to know if the other three branches would work just fine without any WAAS module?
You will need a total of four devices:
2 WAE - Remote Office Accelerators
1 WAE - Main Office Accelerator
1 WAE - Central Manager
The Central Manager must be an external appliance -- it cannot be run on a NME-WAE. I would also recommend an external appliance for the Main Office Accelerator.
