WLC Desgin Question

Hallo toghether,

i plan to install a WLC 5508 controller  with nearly 100 AP´s and 300 wireless clients.

so i need some information or best partice tipps for the  pysical port configuration. If i have understood this right. all Traffic from tahe Clientinto the network

is capsulated in the LWAPP)/CAPWAP tunnel and is encapsulated in the WLC. is this correct. My plan is to use one physical Interface for Management and AP Controll. and i have to map 1 physical inteface for ecach SSID (Vlan). If all traffic which comes from the AP  to the WLC (mangaement taffic and data traffic) is capsulated in the tunnel, the complete traffic pass the physical Interface from the Manaement Vlan ? is this correct? IF yes i think this could be a performance problem becaus all traffic from all ap´s must pass a 1GB Uplink for all traffic  and the wlc forwards this traffic to the spciefied VLAN´s to the core switch? Can me help somebody to understand this better or give me some design tipp how it works better?

Thanks a lot

WLC Desgin Question

Hi Carsten,

I would not recommend this.

Enable LAG & bundle all port into single etherchannel. That's the best way to go ahead

WLC Desgin Question

Hello Carsten,

You are right about the performance issue.

The solution of this (just like Rasika recommended) is to use Link Aggregatoin (LAG).

enabling LAG on WLC will make all WLC connected ports behave like one big port. It is idea is almost the same like etherchannels on switches (but it is not exactly the same).

you can read more about LAG here:

https://supportforums.cisco.com/docs/DOC-20587

The config guide also has some info about LAG.

Re: WLC Desgin Question

Yes both amjad and Rasika are correct by bundling the link the over all capacity of the link increase and check the link if you want to read more about it
