What is the part number of the controller, for example AIR-CT5508-X-K9. X is the AP limit. The maximum a 5500 controller can support is 500APs, but you mentioned "more than 500 AP's". Is your customer using the 2PK version?

Is this the part number of the WLC of customer: AIR-CT5508-250-K9. The customer bought 50 more license, look the part number: L-LIC-CT5508-50A. There are two Controllers that register AP's. The two Controllers has the same number of license in a total of 600 licenses.

Re: High memory occupied in WLC

Emilio: how many clients (min, max, avg) that are connected to one wlc at the same time?

The more clients you have the more memory will be. Used.

What about your cpu utilization? Isit also high?

Hi Abdullah,

The customer has two controllers. One called "WLC Brasilia" and another called "WLC São Paulo". Follows informations about Memory Utilization, Cpu Utilization and Client Count of both controllers. The customer got the data from WCS Server. The informations are separeted in "last 6 months" and "last days".

Last 6 Months

WLC  Brasília

WLC  São Paulo


Last Days


WLC  Brasília

WLC São  Paulo

Re: High memory occupied in WLC

This is strange.

High memory without high CPU and it is only one task that occupying most of the memory!

I guess this is not normal. If you can contact the TAC for this issue.

I am sorry but I am not aware about anyway to fix it. It is abnormal problem as I see.

Regards,

Amjad
