Cisco Wireless :: 3502i Keeps Losing Communication With WLC 5508?

Jan 17, 2013

This problem only seems to affect one of our sites.  Every once in a while, several APs would lose link to the 5508 and get stranded.  The only way to fix the issue is either to power cycle, or better yet SSH into the APs and use the command "capwap ap controller ip address x.x.x.x", and then they'd automatically rejoin the controller.  At first, I thought network hiccups caused the APs to lose connectivity, but there's none that I could find.  I have the primary/secondary controller IPs configured in them as well.  See log below:
 
[previous log entries show AP working as intended, then...] 
*Jan 18 05:29:29.632: %CAPWAP-3-ERRORLOG: Retransmission count for packet exceeded max(CAPWAP_ECHO_REQUEST

Cisco Wireless :: 3502i Cannot Join 5508

Sep 25, 2012

I have a 3502i(AP_1) that will not join a 5508 WLC(WLC_1)(code 7.2.103). The 3502i(AP_1) will join 4402 WLC(WLC_2)(Code 7.0.230). I have another 3502i(AP_2) that will join the WLC_1 & WLC_2. I am using capwap discover through DNS and hard coding the primiary WLC to AP_1 & AP_2. When I debug capwap events and errors, I see the static capwap messages and replies. Both of the WLC are on the same subnet. I have defauted the AP_1 and it joins the CISCO-CAPWAP-CONTROLLER as expected. When I change the Primiary WLC to WLC_1 it goes back to the CISCO-CAPWAP-CONTROLLER. If i change the primiary WLC to WLC_2 it joins. If I change the primiary back to WLC_1 it joins WLC_2 even though it is not a secondary. I know the previous joined WLC are stored in NVRAM, so that might be why it is doing that. I can join other ap to WLC_1 just not this one.

Cisco :: WLC 5508 / 3502i AP Properties

Apr 25, 2013

Devices Used;
WLC = 5508
AP - 3502I
Windows Clients = Windows 7
 
We are using WP2/AES for encryption and 802.1x for key management for our WLAN.  The question I have is, when I look at one of the client's properties through the WLC 5508,  then look at the  "AP properties", its says that its using; Authentication = Open System, and WEP state = wep enabled.  Why would the AP properties have open system and wep enabled when the WLAN is setup for WP2/AES???  There is also a "Security Information" Section just below the "AP properties" section and this lists the correct settings.  Are the "AP Properties" irrelevant in this case?

Cisco Wireless :: Losing The 5508 Snmp Packet?

May 16, 2013

We had a system outage due to power problems a few days ago, and now our WLC is showing short term packet loss when monitoring it using SNMP.  We also monitor it using ICMP, but that shows no packet loss.  I looked at the interface statistics on the WLC and all of the switches in between and there are no errors to be seen.  is there any way to troubleshoot this problem on the WLC?  I am more familiar with IOS than the WLC CLI.

Cisco Wireless :: WLC 5508 Implementation - Some Users Losing Connectivity

Dec 3, 2012

We are implementing a WLC infrastructure in our company following the below scenario:

- WLC 5508, OS 7.2
- APs AIR-LAP1142N-T-K9
- 3 Wlans (1Open w/ Web Auth, 1 WPA2 and 1 802.1x)
 
Issues:Everything seems to be fine, but some users loses connectivity (when connected to 802.1x network) at least 3 times by day.

- I cannot see anything at WLC logs concerning the association/deassociation of any of these users.

- Only strange line in the logs is "RADIUS server 172.21.44.50:1646 deactivated in global list" (authorization server config)

- Also I see some "Coverage hole pre alarm for client" but that doesn't look like a problem...

Cisco Wireless :: 5508 / H-REAP LWAPs Losing VLAN Mapping When Fail To Secondary WLCs

May 2, 2011

I have three 5508 WLCs, running code 7.0.98.0 supporting 100+ LWAPs in H-REAP mode. The LWAPs are servicing 2-3 WLANs each. Some are using central authentication and local switching, some are configured for central authentication and central switching. When the LWAPs fail from one WLC to another WLC, the LWAP's lose all of their VLAN mappings and pick up the VLAN of the management interface on the new WLC.

All WLANs are configured to use the management interface on the WLC and the VLAN mappings are configured per LWAP on the H-REAP properties  tab.  The WLAN ID numbers and all the WLAN settings are the same across all 3 WLC's. I have created AP groups on all 3 WLC's and the AP group config matches across the 3 WLCs.

I can get the LWAPs to keep their VLAN mapping by creating an interface on the WLC with the VLAN ID of the locally switched/remote site VLAN and then setting the interface for the WLAN to the new interface. However, then the WLAN doesn't work, because the centrally located WLC doesn't have the remote site VLAN. It also seems to keep the VLAN mapping if I create the locally switched/remote site VLAN interface on the WLC , and point the WLAN to the management interface. This shouldn't be a necessary step though... In H-REAP with local switching, the LWAPs aren't using the interface on the WLC.

I found a note in the 7.0 WLC config guide that explains why the VLANs are picking up the management interface VLAN, but that same note says the VLAN mappings can be changed per LWAP/WLAN!

From config guide: For hybrid-REAP access points, the interface mapping at the controller for WLANs that is configured for H-REAP Local Switching is inherited at the access point as the default VLAN tagging. This mapping can be easily changed per SSID, per hybrid-REAP access point

Using H-REAP and been able to get the LWAPs to keep the VLAN mapping when failing from one WLC to another?

Cisco Wireless :: 3502i LED Not Remaining Lit?

Oct 17, 2012

I am in the process of deploying 3502i APs. This site has 2 - 5508 WLCs both running Software version 7.0.220.0 and 2 - 4402 WLCs both running the same version of software as the 5508s. All of the APs that I have installed so far have joined the controller and I can associate to them and access the network. When the APs first are connected to the switch they go through the 'normal' boot up with the LED changing colors - white, red, green, blue (not necessarily in that order). Once the AP has completed its boot sequence the LED goes out and remains NOT lit.
 
This is happening to most but not all of the APs. This is the first time I have deployed 3502s - previous experience is with 1142s and 1242s and the LED does not do this with them.
 
I can, through the CLI, turn the LED on but it is then ALWAYS blue, even if a device is NOT associated to it.
 
I do not want to leave them off because the account will believe they have a 'dead' AP and with them always blue they cannot properly troubleshoot using the LED.

Cisco Wireless :: Stand Alone 3502I Without Controller?

May 10, 2012

I have a customer with several older Aironet 1121G WAP's.  In one area of the plant the noise levels from several large motors is preventing reliable connection to the WAP, even though it is located in the same conference room as the users.  I am suggesting upgrading the 1121G to the 3502I to take advantage of the Clean Air technology.  This raises two questions:
 
1) Will a single 3502I be able to effectively handle the RF noise, or does it require a network of WAPs to function properly?
 
2) Does the 3502I require the CT2504 controller for the Clean Air to work, or will it function in a stand alone mode?

Cisco Wireless :: 3502i Cannot Join Controller?

Oct 15, 2012

When we were installing some new APs, were plugged in to ports that were not configured on the WLC management VLAN.
 
This is the illustration
 
WLC management VLAN is VLAN 80 Management VLAN of infrastructure (Switches routers) is VLAN 10
 
The APs were plugged in to VLAN 10 and they were not able to associate themselves with the controllers.
 
Through research, those APs were getting a wrong IP address,
 
I did the Mode button, pressed for 30 secs, but this did not fix the problem, i thought it was going to clean the flash and bring the AP back to factory default I do not believe this happened.
 
We also added the cisco-capwap-controller.localdomain  to our DNS servers, and then I rebotted the APs and still no luck.
 
What fixed the issue is we had to go to the DHCP server, release the IP addresses and we found those based on the macs of the APs. What is we do not have the mac addresses?
 
Now that I have the DNS entry created, if I plug in an AP on the wrong VLAN port will I be able to see it?

Cisco Wireless :: 3502i AP Does Not Download The Code From The Controller

Nov 27, 2012

I am having a Wism on 6500 chassis with software code 7.2.103.0 Now......... I use to have 7.2.111.3 on the Wism before but for some reason I had to downgrade the code to an older version (some compatibility issues with the NCS)......
 
Now before all the APs were having 7.2.111.3 version running as soon as I downgraded the controller IOS most of them downgraded the code but a few still did not show up...... so I picked one of them and did a factory reset on the AP and was guessing that it might get the new code from the controller this way but unfortunately since than I have tried a lot of things but no luck. I have switches configured on layer 3..... other APs connected to this switch are working fine,........ when I reset the AP to factory default it doesnot take an IP obviously so I manually define the IP,,, you would find that configuration below too.... but than after a while it trys to locate the controller and could not find it.... where as, as i said other APs on teh same switch works fine......
 
the only thing i notice is that it does not release the IOS .. it is still having 7.2.111.3.....
 
using MCNG ddr static values from serial eeprom
ddr init done
 Running Normal Memtest...
Passed.

Cisco Wireless :: WLC2106 And 3502i Radio1 Not Showing Up

Mar 2, 2013

I have a WLC2106 and AP3502i. The issue that I am having is the radio for 5GHz is not showing up in "Wireless > 802.11a/n" (see attached screenshot) I am not exactly sure what was the problem. When I went to 802.11b/g/n I do see an entry for 2.4Ghz radio, but nothing on 5GHz.
 
I have the AP plugged directly to my 3550POE, and when I used the command "show power inline" it says that the switch is providing 15.4W and there is still 345W remaining on the switch. The LED on the AP is solid green. I issued a no shutdown on dot11radio1 and the status is up/up, but there is still no entry under "Wireless > 802.11a/n"

Cisco Wireless :: 3502i Ceiling Pole Mounting Options?

Jul 11, 2012

I've got a number of 3502i's that I need to mount in a new classroom that does not have any ceiling (except the floor decking above).  Ceiling is roughly 30-50' up.  Contractors are going to run several 2" (or whatever we want) metal pipes from the ceiling down to a more reasonable level to mount the access points on and get below the hvac ducts/etc in the ceiling. 
 
Problem is I can't find any bracket or mounting options for this!  What are others using in this situation for mounting one of these access points onto a metal pipe such as this?  I've checked Oberon Wireless, Terrawave and I don't see anything glancing through the product catalogs.  Anyone mounting access points this way?

Cisco Wireless :: 3502i - Sporadic Disconnects When 802.11n Is Enabled In Clients

Jul 11, 2012

Recently I upgraded the wireless infrastructure in my campus and deployed WISM2 controllers and Cisco 3502i APs throughout the campus. Until now all my users were using 802.11b/g/a speeds without any issues. However, now I am trying to enable 802.11n speeds in a test group of users by enabling AES encryption and I am seeing lot of issues. These test users sporadically loose wifi connection and an asterix appears in the WIFI icon in the task bar. Interesting part is that all the manually configured wireless networks in the laptop stop displaying. The broadcasted SSIDs continue to show up though. All these users are using "Intel(R) Centrino(R) Advanced-N 6200 AGN" wireless cards with driver version 13.3.0.24. I had upgraded one of the client drivers to the latest 15.1 version. However, he still complained about wireless disconnection (I am not sure about this problem as I didnt personally attend his laptop to know the cause of diconnect).
 
One another interesting incident is that 2 people from this test group were having a meeting in a conference room once and surprisingly both dropped at the same time with the same symptoms. The only fix was to reboot their PCs.
 
I have done following changes in my controllers hoping that the problem would get fixed, But still no luck.
1. Enabled client band select.
2. Checked EDRRM for A as well as B/G
3. Changed Channel allocation from freeze to auto.
4. Enabled "avoid persistent interferers".
 
In my calls with Cisco support we also ran debugs in the controller and sniffer captures in the client machine. All we see in the controller is that the client dropped without any reasons. Also, didnt find anything significant in the sniffer captures. At this point not sure what to do. If upgrading the client driver is an option, then I need to produce some proof or document to the management which says the current 13.3.0.24 has known bugs to run 802.11n speeds. Scanned the entire internet, put a post in intel support site but no luck.

Cisco Wireless :: 3502i - Max Number Of WLANs / SSIDs Configured On H-REAP AP

I was successfully running 2 SSID's at a remote site, one SSID was configured for H-REAP local switching, dropping out to the local site VLAN X, and the other SSID was a central switching guest WLAN anchored to a WLC in a DMZ.I configured a third SSID at the local site running H-REAP local switching, and now I cannot see the guest SSID anymore, it does not appear to be broadcasting.Is there a maximum of 2 WLANs/SSIDs when operating in H-REAP mode?

Cisco Wireless :: Aironet 3502i Adapters Not Allowing Hosts To Connect

Oct 21, 2012

We recently had the Aironet 3502i APs installed in our infrastructure and are having a bad time with hosts connecting to them. The controller sees them, they have an IP, they are showing a solid green light, but you cannot get devices to connect. If you reboot the device you get about 5 seconds of connection and then it disconnects. The only cure seems to be rebooting the APs, but I am baffled why this keeps happening. The installer is blaming our devices, but it is happening to laptops, thin clients, and even cell phones. From what I've seen, everything works fine until, i believe, the device tries to refresh it's lease and is unable to do so.

Cisco Wireless :: Missing AP Multicast Mode IP Causing 3502i AP Radio Resets?

Jun 13, 2013

AP radio resets when the AP Multicast Mode IP is set 0.0.0.0 under the General Tab?
 
I rebuilt my lab controller and moved the management interface to a new subnet. Somehow, the AP Multicase Mode IP under the General Settings was removed. Afterwards, my AP's radios would reset every 2-3 minutes. After comparing my lab config to production, I noticed the IP was missing from that field. Setting the Multicast IP to 239.232.78.1 fixed the issue.
