Distribution of APs on both ports of WLC

[bilal-javed1]

Hi,

I have Wireless LAN Controller 4400 running. Currently all 50 APs are running at one port of WLC. I have studied on Cisco site, that its best to run 24 APs per port of WLC and total 48 in total. My all APs are running at one port.

Can you please tell me is there any issue if i run all 50APs on one port and is this any bottleneck?

Also if i want to shift half APs to second port, What will be configuration for WLC?

Looking forward for your responses.

Thanks

Bilal

I have clients that have one port also and like 300+ Aps:)  it will be your bottleneck, but you need to just monitor it.

So what you mean to say is that its no issue if i run 50APs on one port.

Cisco 4402 Controllers have two Gigabit Ethernet  distribution system ports, each of which is capable of managing up to 48  access points. However, we recommend no more than 25 access points per  port due to bandwidth constraints. The 4402-25 and 4402-50 models allow a  total of 25 or 50 access points to join the controller.

If i want to shift half ports, do i need to enable LAG?

Please let me know. Thanks

I never split the ports, so I was assuming that you would use LAG.

Enable LAG ( Link Aggregation on your controller )

Hi,

Is there any way we can put cap on per user anywhere in router, firwall or WLC?

Becuase from shared pipe, when one user sucks the bandwidth others have to say suffer.

Please guide where should i limit that per user.

Thanks

An old WLC code can ratelimit the downlink traffic, the new codes allow bi directional rate limiting per user.
