NCS report

Hi guys how can I generate a report relating to

repetition of the channels on the WAPs being in a proximity? Want to know the same channels which are repeated / assigned to multiple APs

Thanks

anyone??

Re: NCS report

I do not think there is a report in Prime/NCS for this.

If you want you can get that information using WLC CLI at a given time. Here is the command syntax

(WC01) >show ap auto-rf {802.11a|802.11b}

Here is an example

(WC01) >show ap auto-rf 802.11a AP01

Re: NCS report

I agree with Rasika.... I don't think there is a report unless you generate a report for all AP's and you sort it out. If your looking to see how RRM is assigning channels, you can go to the floor maps and on the Access Points on the left, you can change it to show all the channels and or power levels and look at that data.

You can also download the WLC config analyzer and input the WLC(s) show run-config and that can show you a list of neighbors for a given AP or for all AP's.

Re: NCS report

Thanks Rasik and Scott

Please have a look at the below heatmap

map.JPG

I have got

149, 153, 157, 161 channels for DCA to play with

For some reason it's assigning 153 and 161 only.

Is the channel assignment ok in the map?

Hall of Fame Super Silver

NCS report

It might be due to the fact that AP's can't really hear each other.  I would look at the signal it sees from the other AP's and take a look at how many neighbors on the same channel.

Thanks,

Scott

Any comments re the channel assignments from just two channels only

To assure better diversity of the channel assignments, would it benefit to change the channel width to 20Mhz ..current is 40Mhz

Hall of Fame Super Silver

NCS report

Is there a reason you only have those 4 5ghz channels being used in DCA?  You have more than one country code configured by chance on the WLC?  If so, the WLC will only use the common channels and power levels for all country codes configured.

Thanks,

Scott

NCS report

It's a branch office in Indonesia so we have enabled Indonesia under the country code. so there are just

149, 153, 157, 161 channels available. Is it ok to enable UNI-2 extended channels?

Hall of Fame Super Silver

NCS report

I would not unless all your devices support uni-2 extended.... many do not.

Thanks,

Scott

If your not having issues, I wouldn't worry about it.  The issue is probably that you have multiple country codes enabled on the WLC and one of the country doesn't allow 149 and 157.

Thanks,

Scott

NCS report

Hi Scott, I have only one country code enabled which is Indonesia but still not able to understand as to why the APs aren't using other channels. Is there way to find the channel interference, I suspect this to be the case as lot of people have complained about slow speed when using wireless connection

Hall of Fame Super Silver

NCS report

What AP model do you have and what WLC code?

Thanks,

Scott

Hi Scott, Did you find anything missing in the config?

WLC is Cisco 5500 series model 5508 running

7.2.111.3

All APs are

AIR-CAP3502I-C-K9

Hall of Fame Super Silver

NCS report

You should look at upgrading to v7.4.121.0.  v7.2 was specific for FIPS and v7.4.121.0 is a stable code version.

Thanks,

Scott

Cisco WCS reporting is

Cisco WCS reporting is necessary to monitor the system and network health as well as troubleshoot problems. A number of reports can be generated to run on an immediate and scheduled basis. Each report type has a number of user-defined criteria to aid in the defining of the reports. The reports are formatted as a summary, tabular, or combined (tabular and graphical) layout. Once defined, the reports can be saved for future diagnostic use or scheduled to run and report on a regular basis.

Reports are saved in either CSV or PDF format and are either saved to a file on WCS for later download or e-mailed to a specific e-mail address.

The reporting types include the following:

•Current, which provides a snap shot of the data from the last polling cycle without continuously polling

•Historical, which retrieves data from the device periodically and stores it in the WCS database

•Trend, which generates a report using aggregated data. Data can be periodically collected based from devices on user-defined intervals, and a schedule can be established for report generation.

With WCS, you also have the ability to export any report that you can view, sort reports into logical groups, and archive for long-term storage.
