WLC 4404 bandwidth management

Hi ...
I have a WLC 4404 installed and we would like to manage the bandwidth per SSID.
Today we have configured many SSID because our campus has a lot of wireless users and any SSID has only one class C subnet (/24).
We would like to configure each SSID with more subnets. is this possible ?
Additionally we need to restrict the bandwidth per SSID. is this possible ?
We have some SSID for less important users and we would like to assign the bandwidth per SSID.
Thanks for your help.

Yes with the WLC you can go in and create bandwidth limitations, that are either linked to a user profile, or you can link them to a QoS Profile.
If you link to the QoS Profile, say Bronze, then all you need to do is set the Guest WLAN to be in the Bronze Profile in QoS. If you want to allow certain users to get more than "x" bandwidth, you would do it to a user profile.
******Either way you do this, it only rate limits from the WLC down. ****** It is still possible to saturate a link from the edge to the WLC. So you may want to do some traffic shaping at the edge.\
For the multiple subnet questions, yes you could do that as well.. You'd want to create the interfaces for the new subnets, then use AP groups to link the SSID to a different interface, all based on the location of the AP

Steve

Wlc 4404 strange behaviour

Hello,
I have to manage a wlc 4404. According to me he acts strange.
Only ports 1,2 and 3 are connected. The ap-manager and the management are linked at port 1. So far so good.
If I look at the wireless-tab I see all AP's are connected at port 3 !!
All the 3 ports are connected to the same switch and VLAN.
AP=Cisco Aironet 1130AG with a default config
Could someone explain me why all AP's are connected on port 3, while the ap-manager is linked at port 1.
Thanks in advance,
Carlo

The Cisco docs clearly state that you can only have 48 APs associated to each ap-manager interface. If you are not running LAG, and I can't think of a good reason not to, then you will need 3 physical interfaces to be configured with unique ap-manager ip addresses in order to register 100 APs. Since the APs point to the management ip (via DNS or DHCP) to get the ap-manager interface, they will automatically load balance.
Note that unless you are running VERY recent code, there are significant ARP bugs related to the additional ap-manager interfaces responding to ARP requests. The best-practice is to add a static ARP entry in the router/L3 switch that is the ap-manager's default-gateway. This is an artifact of the ap-manager interfaces not responding to any traffic accept LWAPP, including ARP. This has been a serious problem for a lot of enterprise customers because this impacts most CEF switching devices like the Catalyst 6500 since most IOS versions also have a CEF adjacency/ARP timeout bug.

What settings need to be set for the fastest roaming on my wlc 4404

Hi all
I notice that on my WLC 4404 when walking around with my laptop, I am dropping pings when it roams to another access point, Is there anything on the controller I need to check, and can I optimize these settings for roaming?
cheers
carl

Hello Carl,
to have romaing working fine you need to be sure of following:
1) RF designed correctly , and enough overlapping is availble between the AP's.
in addition for environment to be free from external noise..
this can be confirmed with spectrum expert site survey
2) what authentication and encryption used ( WEP , or WPA-PSK no need to check this point ->> skip :-) )
if you are using any authentication like 802.1x ->> then enable CCKM on the WLAN to make more seamless roaming.
3) if more than one WLC availble on site , configure mobility group between them,
so if client roam from one AP in WLC 1 to AP on WLC 2 ->> no disocnnection observed....
Kind regards

Wireless users getting disabled
Hi,
I have WLC 4404 with 7.0.116.0 version. I was getting following messages for particular APs

After seeing one of the cisco forum, I have disabled RLDP for that particular APs
so above messages are rectified.
But right now we are not able to identify Rogue IP and it is not contained.
So please give any suggetion so that i can rectify the above messages as well as i can identify the rogue IP.
Thanks & Regards
Gaurav Pandya

Hi Scott,
You are right i am not able to detect rogue APs because i disabled the RLDP. but when i enable the RLDP for that particular AP. i got the following messages with interface go up and down
*Dec 20 14:11:13.875: %LINK-5-CHANGED: Interface Dot11Radio0, changed state to reset
*Dec 20 14:11:13.908: %LINK-3-UPDOWN: Interface Dot11Radio0, changed state to up

*Dec 20 14:11:29.700: %LWAPP-5-RLDP: RLDP started on slot 0.
So please suggest me the mid way so that i can enable the RLDP (Detect the rogue APs) with out interface going up and down frequently.

Wireless clients load balancing on the APs on WLC 4404

Hi Experts,
I'm just wondering if the WLC 4404 with firmware 4.2.207.0 can load balance the wireless clients on different WAPs. Let's say that an AP is already handling 15 Wireless devices. When the 16th is trying to join, the controller somehow puts it on another nearby AP, even the signal from this AP is weaker. I heard the similar feature on other Wireless solution vendors. I'm just wondering if Cisco has the similar feature or not.
Thanks!

Yes it is known as aggressive load balancing sending a code 17 making the wireless client to loook at another nearby AP.
here it is the documentation:

lost GUI session
Lost console conection
Lost SSH and Telnet conecction

Almost looks like it could be defect ID CSCtx02515. SHows that it's fixed in 7.2.110.0, but if you have a 4404, you can't run 7.2 code.
Symptom:
High CPU on webJavaTask
Alternatively: large number of TCP connections, leading to file descriptor problems like:

Bandwidth Management for Software

Is there a utility out there that would allow you to allocate specific amounts of bandwidth any software could use? In many download managers (such as Speed Download, Limewire, Azul, etc.) you can easily set the total amount of bandwidth and even per file download parameters. I have always been surprised that browsers such as Safari and even iTunes does not allow you to control the amount of bandwidth it is to use when downloading.
I often find myself in situations where I need to download a large file, and yet be able to continue to surf for example, or else I would like to keep the setting in my iTunes to download podcasts automatically when I launch it. Both Safari and iTunes, will take as much bandwidth as you can throw at them which means that it can grind every other on line activity to a halt (specially when you do not have a blazing fat connection).
Anyone know of any such software?
Thanks.

Thanks, but I don't understand what this has to do with bandwidth management? Perhaps I do not understand the capabilities of nice, but isn't nice just a way to prioritize applications and services? How would you use it to allocate bandwidth?
By giving various jobs different priorities, the effective bandwidth is limited. If you use 100% of the bandwidth for 1% of the time and 0% of the bandwidth for 99% of the time, you are effectively giving the "niced" app only 1% of your bandwidth. And since a computer is digital, there is really no such thing as "instantaneous" bandwidth, as there is in other areas of communication.
If you have 10 processes running and each consumes 10% of your total bandwidth, it does not matter whether the processes are time-shared or bandwidth-limited, when considered over any reasonable period of time.

Bandwidth Management(Rate Limit) Using QoS Policies

Hello,
I need some advice. We have an ASA 5525 running version 8.6(1)2 and a 10 MG pipe. I have execs that want to limit bandwidth on users for stuff like youtube, stream media, and downloads. I found the article on ‘Bandwidth Management(Rate Limit) Using QoS Policies’ so it appears our firewall can do what we want. I’m not a cisco person. My knowledge is limited when it comes to configuration – that’s why we have SmartNet :). The advice I need is what to ask for, so to speak, when I put a case in. Can bandwidth be limited on end users and/or can they limit the ‘bandwidth rate limit’ to just youtube, steaming media, and downloads? If so, what should the limit be? and I’m assume this would be for ‘incoming’ traffic only? we’re running into some bandwidth hogs – usually youtube and/or streaming media. We have a Barracuda web filter which we’ve used to block and monitor activity but I simply do not have time to babysit this all day. I should also mention we do have critical data running up and down the pipe; such as credit card processing, DB replication between in house DB and hosted website, TPCx and EDI, FTP, and such that we don’t want restricted.
Need input please,
Thanks,
D

Hello,
That's a question that you as the network admin of that organization could answer.
How much traffic for business purposes must travel via HTTP/HTTPS?
How much bandwith are you willing to provide to this 2 protocols?
Those are the kind of answers you need to answer before setting the number

WLC 4404 - Clearing the Load Balancing Statistics?

Does anyone know of a way to clear the load balancing statistics from a WLC 4404? I've looked through the gui and CLI and can't seem to find a way to do it.
Thanks,
Rob

You can do a 'show summary' to see the number of connections that have been sent to each servers.
You can't see the number of bytes so.
I would suggest to collect this info on the server.

Replacing WLC 4404 with 5508

Hi Friends,
I am new to Cisco wireless and would appreicate any help with replacing WLC 4404 with 5508. I mean any link or doc (best practices).
Thansk,
Nav
[email protected]

Yup, what said Scoot said .. Add the 5508 to the aps high availability. If you have WCS/NCS you can push this to the APs.

Decrypt Errors - WLC 4404

Hello,
We recently had a few clients being locked down with countermeasures by our WLC 4404 due to TKIP-MIC errors. After doing some reading on the benefits of AES over TKIP I switched our WLAN security settings to AES, and pushed a new wireless policy to our client machines. Every thing appeared to work well, except now the trap log on the 4404 is showing a LOT of WPA decrypt errors. I've checked a few of the clients that appear to have problems, but they've got the right policy and WPA settings to match what is on the WLC.
It's not one particular NIC, it's various clients.
Any thoughts on how I might clear these up?
Rob

One reason for that is configuration of two WEP keys on a single WLAN is not supported. Currently WLAN can only take one WEP key.

Wlc 4404 upgrade

Hi, looking for advice on which code to upgrade to. We have a wlc 4404 using mostly AIR-AP1231G-A-K9 access points. The current code is 4.2.130.0. We would like to use some of the 1141 APs and I understand they need at least 5.2. My plan would be to go to 6. I believe I need to go to 4.2.176.0 first and then to 6. The question would be what version of 6 would be the best? Right now 6.0.182.0 (ED), 6.0.188.0 (ED), and 6.0.196.0 (ED) are available.

Well that is a tricky question and really depends on a lot of variables. We have installs with all three versions of the software. Currently I would have to say that 6.0.188.0 is one to try. We have upgraded some clients to 6.0.196.0 because of issue with the 6.0.188..0, but again, it all depends what equipment you have and if you see any issues with the 6.0.188.0. Some people I know have just went right to the 6.0.196.0 code and have not seen any issues. The 6.x is still pretty new in my book, but like you already did..... review the caveats on the different versions and if you have a spare WLC,do some testing.

WAAS - Bandwidth Management support?

WAAS - Bandwidth Management support?

Sorry, I had a problem with the web. My comment was:
I know that other products such as Juniper's WXC supports Bandwidth Management. Does Cisco WAAS support it too?
Bandwidth Management means:
- Guarantee a minimum bandwidth for your most critical applications.
- Set maximum bandwidths to limit (or drop) low-priority traffic.
- Set priorities to determine how the âexcessâ bandwidth is allocated.
Thanks in advance.

Upgrade BootLoader on Cisco WLC 4404

What is the latest Bootloader for the Cisco WLC 4404? And where can I download it?
My current versions are:
Product Version.................................. 5.2.178.0
RTOS Version..................................... 5.2.178.0
Bootloader Version............................... 4.0.206.0
Also is there a reason to upgrade the bootloader image?
On this webpage http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00805f381f.shtml it shows the steps to upgrade WLC are :
This sequence is recommended for your WLC software upgrade:
Upload a backup of your controller configuration to a TFTP server.
Disable the 802.11a and 802.11b/g networks on your controller.
Upgrade the primary image on your controller.
Upgrade the boot image on your controller.
Note: This is a required step for upgrades to 4.1 on the WiSM, 3750G Wireless LAN Controller, and 4400 Series Controllers.
Re-enable the 802.11a and 802.11b/g networks on your controller.
I get the primary image is just going to be AIR-WLC4400-K9-6-0-196-0.aes. But where do i download the Bootloader and it looks like i just do the same thing i did with the primary image.
I think I am missing something.
Thanks

The boot software image consists of the controller boot kernel and boot menu script. that is.. when you use the WLC for the first time. then you will be able to use this while entering the username, mobility information.. interfaces informations etc.. the Software version is the one which you issue CLI commands...or even simple example wil be.. reboot the WLC and hit ESC.. the software that you access at this time will be boot loader..
to upgrade the bootloader...
