Cisco 5508 Controller 5GHz band selection

hi,
today i installed one Cisco 5508 Controller with 1262 APs only with 5GHz antennas. all radios are came up excpet 5ghz band, i tried all my level of best to get it UP. can anybody tell me if there is anything we need to really inspect to enable 5 GHz band.

Cisco 5508 controller

I have Cisco 5508 controller in our high school. I changed the password for one of our WLANs yesterday.(WLANs>WLANs>WLAN in question (in my case OBSD-Internal)>Security>Layer 2. For some reason it reverted back to the previous password ( this was confirmed by a client attempting to connect). What could possibly cause this?

Hi Sean,
May be you did not saved the config on WLC(After changing the password).

Block P2P traffic on Cisco 5508 Controller

Is it possible to block outside P2P traffic on a guest wireless network using an ACL on the controller? I know we can do it our firewall but the question came up so I thought I would post and see what everyone thinks. TIA

Yes, ACLs can be applied to the WLC. I might suggest moving the ACL to the closest point, the FW if you are concern about internet traffic.

Redirect to web authentication not working on Cisco 5508 Wireless Controller

Hi,
I have a wlan with web authentication:
http://i55.tinypic.com/w145zk.png
and
http://i51.tinypic.com/344sfm0.png
When I connect to the SSID (I get correct IP from the Cisco 5508 Controller) and try to surf, I do not get redirected to the web authentication page (https://1.1.1.1/login.html), when I manually insert the URL I get "cannot display the webpage". Any idea?
The virtual interface is 1.1.1.1.
Here is a screenshot of interface and internal dhcp:
http://i52.tinypic.com/2vkm1d2.png
Any idea why clients are not redirecting?
Thanks!

Thanks for the reply dmantil!
When I changed the Virtual DNS name to 1.1.1.1 (the same as the IP) I get redirected if I use http://198.133.219.25, but not with http://cisco.com, I get redirected only if I use IP.
I forgot to mention that the controller is in a lab with no access to DNS server. Does the controller check if the domain is valid before redirecting users? I cant find any documentation on how the controller redirect users.

5508 Controller & Muliticast

have a Cisco 5508 controller (version 6.0.199.4) that when I enable global multicast mode it will work for an hour or two and then it will kill the network. All internet both wired and wireless, access to server everything dead. I then have to directly connect to the service port and disable the global multicast mode. Then two reasons for enabling it are Docs2Go and LanSchool both require multicast to be enabled. I have it enabled on our wired network and it works OK there. I am probably just missing something stupid. Any thoughts or suggestions would be greatly appreciated.

On the Controller tab.
so if you're not setting a multicast address, then you are running in Unicast mode.
Multicast - Unicast - This is the easiest method to use. When the WLC receives a Multicast packet, it replays that packet to every AP that is connected. Now this does work, but can be very network intense, as every AP gets the stream. So if you have 100 AP, there are 100 streams, 300 AP 300 streams.
Mulicast - Multicast - This is the better method to use. With this method, the AP will join to a multicast group, that you configure, preferably in the 239.x.x.x administratively scoped space. Now when the WLC gets a mutlicast packet, it replays it once to the group.
Now, the WLC side is easy. Select Mutlicast - Multicast and configure your group, each WLC in your mobility group should use a unique address. For the WLC you are done.

VLAN assignment without ACS on Cisco Wireless Controller 5508

I was wondering if it is possible to do dynamic VLAN assignment on the Cisco Wireless Controller 5508 without using Cisco ACS but use Microsoft NPS server instead? Is there a manual or article that someone can point me in the right direction?
Thank you!

Any RADIUS server will allow you to do the dynamic vlan assignment if you configure the right RADIUS attributes (64, 65 and 81 that Steve mentioned above).
This doc shows example of dynamic vlan assignment with WLC and ACS.
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008076317c.shtml
Same config on WLC is needed. However, on the RADIUS you need to configure the same attributes on the NPS instead.

Cisco 5508 Wireless Controller with Splash Page Disclaimer

How do one configure a splash disclaimer page on a Cisco Wireless Controller 5508 with no authentication?
Jimmy

There are many options to you in this scenario, but if you're looking to simply provide a splash page via the WLC without interacting with any other web servers, you can configure Local Web Authentication (LWA) as seen in this configuration example.
http://www.cisco.com/c/en/us/support/docs/wireless-mobility/wlan-security/69340-web-auth-config.html?referring_site=RE&pos=1&page=http://www.cisco.com/c/en/us/support/docs/wireless-mobility/wlan-security/71881-ext-web-auth-wlc.html
If you are not wanting the authentication, you can choose the "passthrough" method which will not require any credentials, only accepting an AUP or whatever you want.

Cisco 5508 and Ipads

We have cisco 5508.
We had problems with the connection of the first and second iPad version. Firmware: 7.0.235.3. Putting firmware 7.x. we can not because we have a point of 1310. But we put the firmware 7.2 ipad still have not get wireless. Then we rolled back. It is interesting that not only work the first and second iPads. All the above works. Played with TKIP instead of AES, did not help ...
P.s. iphone works.

Getting disconnected randomly (5508 controller, 3300 series LAPs)

I am at one of our remote offices and I am noticing my laptop, despite excellent signal strength is periodically losing IP connectivity on the wireless network. When it drops, all of my IP connectivity stops (pings fail, RDP sessions "await reconnection", etc...). The lower right corner still shows I'm connected to the hidden WPA2 Enterprise SSID. The only way to reconnect is to select disconnect on it, then click connect again. Immediately everything IP based starts working.
There is a 5508 controller in the headquarters. The site I am at has a 30mbps fiber point to point WAN to the headquarters. This site has 2 x 3300 series LAPs which are very good coverage. H-REAP mode is on so traffic terminates at the local office because it is more efficient than traversing the LAN twice for things like local file and print sharing, dhcp, proper active directory sites and services mapping, etc...
The 5508 has a 2008 R2 server running NPS to do radius authentication and it verifies a domain certificate. To be on the wireless you have to be a member of the domain.
Seems to not give me any problems at the home office so any idea's?
On the 5508 I see this around the times I lose IP connectivity:
*Dot1x_NW_MsgTask_4: Jan 08 14:00:53.599: #DOT1X-3-INVALID_WPA_KEY_MSG_STATE: 1x_eapkey.c:861 Received invalid EAPOL-key M2 msg in START state - invalid secure bit; KeyLen 24, Key type 1, client 88:53:2e:xx:xx:xx

I have 0 (unlimited) as the max for user login policies so not sure why Authentication Aborted message appears.
WLC Software version
7.4.100.0
On the NPS server (2008 R2) I just see my username granted access because it matches the network health policy.

Well I'm going to try to move the EAP-Broadcast Key Interval back. It was set to 3600 which in seconds equals 1 hour. Seems like not only my laptop but others now have been reporting that every hour on the dot, they stop passing IP traffic. The regular users just reboot, while people "in the know" disconnect and reconnect, and they are good for an hour.
Towards the bottom of this thread here:
https://discussions.apple.com/thread/3753111?start=0&tstart=0
They suggested this.
I ran this
(Cisco Controller) >config advanced eap bcast-key-interval 86400
Now when I show advanced eap I get this:
EAP-Identity-Request Timeout (seconds)........... 30
EAP-Identity-Request Max Retries................. 2
EAP Key-Index for Dynamic WEP.................... 0
EAP Max-Login Ignore Identity Response........... enable
EAP-Request Timeout (seconds).................... 30
EAP-Request Max Retries.......................... 2
EAPOL-Key Timeout (milliseconds)................. 1000
EAPOL-Key Max Retries............................ 4
EAP-Broadcast Key Interval....................... 86400
I just will take note if this fixes the problem or not. If it does not maybe I will return it back to the default 3600.
Your idea of a hidden SSID in the clear to rule out auth issues is a good one, but security wise I don't want an open SSID - hidden or not for an hour in public places. Sure I could throw it on a VLAN with just one server and run a continuous ping... but I'm at the home office now which never has this issue.
Seems like when it's time for the key to be renewed, I'm thinking the renewal handshake at remote sites is just not making it back to the controller. However the initial key handshake when you first boot up or associate to the SSID goes over the WAN no issue. I only say this because at the home office where the WLC is physically located, there is no issue.
The WANs are a minimum of 10mbps over a Ethernet Virtual Private Line which is a busness level service provided by Verizon.

Aironet 1041 Standalone 5Ghz Band

Hi,
I'm doing a basic install of X8 1041's.
All devices are to be connecting on the 5Ghz band.
The spec of the 1041 states its supports 802.11 a/b/g/n on 2.4Ghz + 5Ghz band.
When configuring the 1041 I only see options relating to the 2.4Ghz band, I see nothing for 5Ghz.
Am I missing something really simple here, how do enable the 5Ghz band?
Any help would be greatly appreciated.
Many thanks,
G

The spec of the 1041 states its supports 802.11 a/b/g/n on 2.4Ghz + 5Ghz band.
That's incorrect. 1041 only has one radio. And it's the 802.11b only. 1042 is the model with both 802.11a and 802.11b radio.

Band Select - Acceptable Client RSSI.

Band Select, "Acceptable Client RSSI".
Is the RSSI in this parameter the RSSI measured from the 2.4GHz or 5GHz?
Is it the signal the client measures from the AP, or the signal that the AP measures from the client? (I assume AP measures from client).
Also how would you go about determining a "good" setting for "Probe Cycle Count (for a client neutral network)? The default is 2 but I think it used to be 4. 4x200ms (scan cycle period threshold) is 'only' 800ms which is not all that long IMO if it helps more traffic get to 5GHz.
Thank you.
-Dale-

Dale,
The RSSI is measured from the 2.4ghz and it's from the AP not the client. Does this work all the time... No it doesn't. The issue you might see from extending the default settings is the device might not connect at all. The client device will make the final determination. You will need to test and decide what works for your devices.

Details about Band Select feature

Hi Board,
currently I want to prepare a WLC test series. Now I'm stuck at the Band Select feature. I'm not clever enough to completely understand the functionality by reading the 7.2 software configuration guide or this document https://supportforums.cisco.com/docs/DOC-20630.
This is how I understand the single settings and timer.
In my examples the default settings are assumed:
- Probe cycle count: 2 (default)
- Scan Cycle Period Threshold: 200 ms (default)
- Age out dual band: 60 seconds (default)
- Blue arrows indicates usage of the 2,4 GHz band
- Blue arrows indicates usage of the 5 GHz band
Case 1: Client ignores band select
- After the first (initial) probe request of the client, the probe cycle count is already increased by one (so it is "1" right now)
- Probe requests from the client, which are within the scan cycle period, are ignored - the probe cycle count is not increased (dotted line)
- After the next probe request, which is after the scan cycle period, the probe cycle count is increased by one (so it is "2" right now)
- Because the max probe cycle count is set to two (meaning that two probe requests are suppressed), the next probe request is answerd. It does not matter if the next probe request is within the scan cycle period or not, because it is not needed to increase the probe cycle count again (it is already max = 2)
Case 2: Client doesn't ignore band select
- After the first (initial) probe request of the client, the probe cycle count is already increased by one (so it is "1" right now)
- Because the client does not receive an answer to the initial probe request, it tried to send the probe request in the 5 GHz band.
- The 5 GHz probe request is answered immedately.
- Then the client is associated to the SSID in the 5 GHz band. Probe requests by the client in the 2,4 GHz band within the "age out dual band" time (60 seconds) are ignored by the AP.
When does the "Age out dual band" timer actually starts decrementing? After the clients successfully associated to the 5 GHz band OR after the AP sees the first probe requests in the 5 GHz band? How does the AP know that probe requests in the 2,4 GHz and 5 GHz band come from the same client? The radio interfaces of the client have different MAC addresses! So how does the AP know, that probe requests in the 2,4 GHz band (MAC A) comes from a client, which is already associated in the 5 GHz band (MAC B)???
Are my assumptions right? Does someone have paper or a link, which describes this feature more in depth?
Best regards
Joe
Edit: Case 2 extended by the "age out dual band"

Band select steer A/G client to use A and doesn't work other way.
Client will keep probing even after client associated to AP, however AP doesn't care those probes if they're already connected to it.
When does the "Age out dual band" timer actually starts decrementing?
as soon as wireless client connected to AP on 5ghz
How does the AP know that probe requests in the 2,4 GHz and 5 GHz band come from the same client?
Wireless client uses same MAC irrespective of Radio 2.4/5ghz is used, Physical device has one MAC only, unless custom wireless driver used to create virtual MAC at software.
If there were one MAC address per radio then it is possible to connect to two different WLAN, Use one b radio to talk to AP and use the A radio for bridging.

How can I set up 3 different VLANs on Cisco 5508

Dear Community Members,
I have a need to setup three (3) VLANs with different SSID's for students , staff and visitors in a College.
The controller is Cisco 5508 with Cisco 3502E-E-K9 AP
presently the wireless network is flat with just one VLAN
NB.
Staff would log in using active directory user name and password.
Student would log in using username and Registration number Possibly using RADIUS SERVER
How best can i achieve this.

Scenes you are using single vlan so the point of have multiple SSID is useless and the better approach will be using the AD for both authentication and managing the Group policy for both. In this way you can manage both students and Staff Kindly see the following link for step by step config and understand Group policy

LWAP issues with a 5508 controller after AP upgrade

Hi All, I’m having a few problems after upgrading my AP to a LWAP and hope you can help.
I have an AIR-AP1242AG-E-K9 which had c1240-k9w8-mx.124-21a.JA loaded, I followed the link below and upgraded with Cisco’s upgrade tool to c1240-rcvk9w8-mx with no problems at all, after the upgrade I could then see the LWAP on the 4402 controller and had it working a treat.
Now the problems begin, I brought it into the office where we have 5508 controllers, plug in the LWAP into our management switch and boot it up I get an IP assigned from the DHCP server and the AP goes into discovery mode but never finds the controller.
I have logged the boot process but this does not give much away, our other 1100 series AP’s boot fine, I was hoping that somebody here could help me resolve this issue.
