I have an upcoming implementation and I need your advise/recommendation on how to do the implementation. Attached is the network design with the APs and SSIDs. The 2 offices will be connected by fiber and will be L3 connectivity. The WLC will be connected in the new office. APs in the new office will be 'Local mode' and dynamic interfaces will be created for WLANs in the new office. For the old office, will the APs be in 'HREAP/Flexconnect mode'?
Any recommendation/advise will be highly apprciated.
The underlying question I would like to get out of the way is what bandwidth do you have with your fibre optic? Is the link a full 1Gbps (or more)?
If the answer is yes, then why go FlexConnect? Configure the APs as local.
The only time you'd want to use FlexConnect is when you have a bandwidth limitation with your WAN link and you want to minimize the chatter between your APs and your WLC.
What is the typial dealy between these two site across your 1G fibre (is it ~ 10ms ?). Then it is like two buildings just L3 hop away & should not have any performance concerns over WAN.
Anyway you have the FlexConnect & Local mode options here. Keep in mind FlexConnect is not feature-rich as local mode.
I am more towards Local mode deployment, if delay & bandwidth is not a concern.
**** Pls rate all useful responses *****
Typically I would deploy the old office as FlexConnect local switching and the new office as local mode. Makes the most sense in many environments. The only reason why you would put the old office also as local mode is if you have the bandwidth and if all resources have to come back to the new office, like printing, etc.
