Team,
I am deploying 54 3802i AP's on cisco 2504 wlc and want to get the best performance possible and wonder if, I deploy the AP's as flexconnect will give me any benefits of local switching performance boost instead of tunneling back to the wlc 1GB on local mode.
Gear:
3650's switches
3802i AP's
2504 WLC's
Don't have the luxury of putting the AP's on 10mGig but want to get the best performance possible over 1Gb.
Thanks

Aaron,
No problem.
WLC 2504 have a total maximum of 1gb throughput. The bottleneck is that it only handles 1gb from the switch into the WLC so all the APs CAPWAP tunnels will share that 1gb. So in this case I would go with flexconnect. In flexconnect all client data traffic will be dropped directly onto the LAN and not tunneled to the WLC.

Jonas

Hi Aaron,
Well it depends,
Is the APs and WLC on the same site? How much data do you think will pass throu the APs/WLC?
WLC 2504 have a maximum throughput of 1gig so if you think you will push more than 1gig total spread over all your APs then Local mode on 2504 is a nogo.
Also the 2504 have a EOL set to 2023 and the last supported version is 8.5. Maybe the 3504 could be an option if you dont already have the WLC.
Otherwise I would go with Flexconenct. Correctly setup there are no performance drops when comparing to local what I have experienced.

Jonas

Hi Scott,
As suggested by you, it would always be better to first study the deployment requirement. If for the case of APs in local mode, the wlc uplink utilization is well within the limits, then local mode could be the better choice.
Is there any means from controller to verify the %age utilization of the WLC uplink?
Through NMS we could be able to do so, however will there be any means to check it directly from the WLC as well?

Thanks Scott for your valuable responses.

I agree with Scott that usually 1gb is enough. But it always depends on the use case. For example I'm involved in building an event where we use two 5520 in HA and about 200 APs. On that deployment we peek 7,5-8gb and have about 4-5gb constant.
Look at your requirements and make your decision based on that.
regards,
Jonas
