Cisco 2106 Can't See APs
Oct 20, 2011
I was handed a Cisco 2106 WLC and 6 AIR-LAP1131AG-A-K9 acess points a few days ago and was told to get it working. My problem is i have never worked with cisco products, so i have been stumbling setting this up. Here is what I did get working Web interface into the 2106 WLC I flashed the 2106 from version 4.x to 7.0.116.0 I get green connected lights on numbers where AP are plugged in I configured the ap-manager area to settings of
Port Number=6
Vlan Identifier=0
IP Address=10.0.0.254
Netmask=255.255.248.0
Gateway=10.0.0.1
Primary DHCP Server=10.0.0.18
[code]....
I have logged into the console port on both the WLC and AP but i do not understand how to see reports or enable reports on either device to see what is wrong. I read that the AP can be set to lightweight or anon mode but i do not know how to check to see what mode they are currently in.

I have a problem with pinging APs that are connected to WLC 2106. We have a TRUNK with VLAN50, VLAN51 and VLAN71 (all tagged) connected to our WLC 2106. VLAN50 is our management network. We have configured bot management and AP-management interfaces on WLC with IP addresses from our management network and we have set both to VLAN 50. We have also configured static IP addresses on every AP, connected to WLC.
The problem is we cannot ping APs. This means that APs can’t connect to any other device on the management network and we would like to use RADIUS for WiFi client authentication.
How can we solve this problem? I guess if we configure VLAN50 as native untagged VLAN in our TRUN, this would work? Is there any way to configure this without using native VLAN?
We also have problem with IPv6 connectivity. We have configured DHCP and we are using 1.1.1.1 DHCP proxy and it works great for IPv4, but how can we configure DHCP proxy for IPv6 addresses? Our WiFi clients need to get also IPv6 addresses. I have enabled “IPv6 enabled” option on the WLC.

I've just installed a 2106 Controller at a remote site. The Controller is seen by the WCS at the main site so, connectivity is good and I'm able to login from the main site. I've configured the DHCP server which is at the Main site on the AP manager interface and the Manager interface and on the WLAN of the new controller but, APs are not getting addresses.

I bought a brand new 2106 WLC and a 1142AP. After going through the standard setup, the 1142 LAP was blinking red, yellow and green. I checked the logs and found the following message; [code]
I requested the latest IOS and Boot image for the controller from the supplier but he has provided only AIR-WLC2100-K9-7-0-220-0.aes, no equivalent boot image and has insisted that it is enough to upgrade the controller.
Is the AIR-WLC2100-K9-7-0-220-0.aes compatible with the 1142 LAP? And would I be able to upgrade the controller with only the AIR- WLC2100-K9-7-0-2 20-0.aes IOS and no equivalent boot image?

We recently purchased a bundle of 3 1042N AP's with a 2106 WLC. I am able to get the controller on the network and am able to manage it through the https web gui. I am now trying to add one of the AP's to the controller and am getting an infinite loop on the AP upon bootup. I tried looking up the solution but could not find a good article that pertained to the problem I was having. One thing I did notice is the time on the AP is way offset, but when I do a clock set to change it to the actual date it doesnt stick on the next reload.
Here is the output:
using ÿÿÿÿ ddr static values from serial eeprom ddr init done
Running Normal Memtest...
Passed.
IOS Bootloader - Starting system.
FLASH CHIP: Numonyx P33

I hava installed a WLC 2106 with 4 1252 Aps. Some laptops has dual radio wireless card, but others has just 2.4 Ghz card.
I have one SSID with WPA2/AES and 802.11X authentication.
With the laptops with dual radio the speed is in 300 Mpbs, but when is single 2.4 radio the max speed is 70Mpbs
If i use a 1252 ap with autonomous IOS, SSID with WPA2-PSK/AES this laptops single in 2.4 works to 144 Mbps
is there a knowed issue about 802.11x in 2.4 Ghz or i need to make a different configuration to can work in 2.4 with a speed of 144 Mbps?

I got my final assignment from school, and my teacher asked me to configure 2 Access Points (1200 series) directly on a Wireless Controler (Cisco 2106). I can't ask my teacher for any questions, cause he doesn't know how to configure it also, THAT's why he's asking me to do it.I've learned a lot of things about the default static interfaces (the "management" and "ap_manager" interface), but i can't seem to fully understand how to configure it.I want to use the Internal DHCP server of the WLC. How I can get those 2 Access Points working on the WLC. I only seem to get DHCP issues.
This is what i've done:
- Leave the configuration of the "management" and the "ap_manager" default (172.16.1.30 and 172.16.1.30). Bound to port 1
- Made a new interface "AP1" with IP-Address 10.0.0.10 (/24), default gateway 10.0.0.1. Primary DHCP server: 172.167.1.30
- Made a new interface "AP2" with IP-Address 192.168.1.10 (/24), default gateway 192.168.1.1. Primary DHCP server: 172.167.1.30
- Made 2 DHCP scopes within the 192.168.1.0 and 10.0.0.0 networks.
For some reason, when i boot up both AP's, the won't get any DHCP address.

We are trying to configure our 2106 wireless lan controller to expire wireless users sessions so the user is not remembered indefinitely. We are using freeradius to validate the users login information and passing back a "session-timeout" avpair but the WLC seems to be ignoring this value.
How to configure the session expiration time of wireless users on a 2106?

We have a 2106 that was configured by a former employee. No one left in the company is qualified to configure it. The wireless guest access used to work fine. We'd configure a guest user account. They would connect to the guest wireless, open a web browser and login. For some reason now there is no prompt for login. People can connect to it and get an IP address, but that's it. No login prompt or anything else from there.User Login Policies was set to 0 and I put it to 8. That didn't do anything. Under Web Auth > Web Login Page it's set to Internal (Default).

I setup a mini wireless LAN network lab with a not for resale 2106 wireless lan controller and a sales air-lap1242ag access point. I do not have a DHCP and DNS in my lab environment. I have configured the WLC with the basic configuration using the CLI wizard, i also configured the WLC as a DHCP server for clients that will be connecting to the APs associated to the controller.
I powered up the AP and connect the ethernet port directly to the controller, the controller issued an IP address to the AP, the AP downloaded a new operating system from the controller but failed to join the controller.
I check both debug message on the controller console and the trap messages on the controller's GUI and it say the AP could not download a configuration from the controller and it is beacuse of invalid license. Below is the trap message:
Configuration Phase Statistics Requests ReceivedResponses SentUnsuccessful Request ProcessedReason For Last Unsuccessful AttemptLast Successful Attempt TimeLast Unsuccessful Attempt TimeLast Error SummaryLast AP Message Decryption FailureLast AP Connection FailureLast Error Occurred Last Error Occurred ReasonLast Join Error Timestamp
Also, I tried to log into the GUI of the AP using the both the username and password ''Cisco'' but I cannot get into the device. I can only get in through the CLI. In the CLI, almost all the commands I enter gives an error the it is disabled. I don't know what to do any more, I want to know if the access point is faulty or i am not doing the right thing.

I have a WLC 2106 and 1242AG.it's a hotspot configuration.So in WLC, under controller tab, i have set my ap-manager ip, my management ip, my virtual ip (1.1.1.1) and my hotspot network range ip.I set also a DHCP range for the hotspot network.
In Wlans tab, i set my hotspot wlan, with no layer 2 security and for layer 3, i set none for layer 3 security and i use web policy authentication.I use local authentication and i created under security menu, under AAA tab, 3 local net users.
From pc number 1, i get ip from dhcp, and i have authentication web page, authentication is ok and i can surf on web.From pc number2, when user 1 from pc 1 is connected, i get ip from dhcp but i have not the authentication web page, i have not DNS resolution.when i try https:1.1.1.1/login.html, i have no answer.
And when user 1 is de-authenticated, the user 2 can surf on web.So only one user can surf at the same time. not good for a Hotspot.

we operate a number of 2106 WLC's some of which are in training centres, we have been requested by one customer that the SSID used for the users in the training rooms is only enabled between the hours of 9am - 6pm Monday to Friday.
As such im trying to find an automated method of disabling said WLAN automatically outside of these hours including weekends.
Im aware that the commands:
config wlan disable "WLAN ID"
config wlan enable "WLAN ID"
Can be used to perform the required function but getting them to trigger at the appropriate time is proving more of a challenge.

I have a problem with Cisco WLC 2106 (SW: 7.0.98.0) and LAP1262. The client roams to new AP, associates with the new AP and authentication (WPA2 with EAP-TLS) runs fine until WPA2 key exchange.
The first WPA2-Key-paket from AP (1 / 4) is sent twice. On a closer look at those packets with Wire shark, i've found out the first is encapsulated into a 11n-frame (A-MSDU). The resent frame isn't. This figure shows the first WPA-Key-packet:
The next figure shows the 2nd key-packet, without 11n-encapsulation: The problem, that occurs a very long roaming-time with about 5 seconds. As you can see on second figure, the second wpa-key is sent 5 seconds after the first.
Some details:
Client: Tablet PC with Intel 6230 agn
Controller: Cisco WLC 2106
AP: LAP 1262
Controller SW: 7.0.98.0
Encryption: WPA2-AES
Authentication: EAP-TLS
This problem occurs just on 5-GHz interface with 40 MHz channel bandwidth.

I have been having problems with a 2106 WLC which seems to have developed a fault. I cannot console into the device (although I can console into the ap1131ag showing no fault with the RJ45 - 9 Pin) and the device is no longer showing up in any of the possible I.P ranges.
Its showing a power light and a status light on the front panel, the Ethernet ports light up like a Christmas tree when a device is connected and the power supply is putting out a solid 47.7v.
Has anyone experienced anything like this before and can anyone suggest anyway of breathing life back into it?

after an unplanned power outage the WLAN in our office has stopped routing. Clients can associate and get an IP address from the DHCP server on the controller but cannot get past the controller. A PC on the LAN can ping the default gateway of the SSID (dynamic interface) but cannot ping the client. Attached is a diagram of the setup. I am trying to find out how to add a default/static route via the L3 switch that the controller is connected to but am unable to do so either through the CLI or GUI. The controller (AIR-WLC2106-K9) is operating on ver 5.2.157.0.

I have a very basic WLAN setup with a 2106 controller and 3 (will be 4) 1140 APs.As part of securing the network I have been testing the rouge detection. The system has no trouble detecting and shutting down honeypots. I would like to also automatically shut down Rouge on Wire points. The system sees my test AP just fine. And I have it completely open (no security). But the system never detects that the rouge is on our network so no action is taken. I can connect just fine to the test AP with no encription using DHCP and communicate with everything on the network just fine.Is there some setting I am missing that allows the APs to detect that an AP is on wire?

I have a WLC 2106 with 3 APs. Everything works and users can connect, but the throughput seem to be lower than it should (it is around 8Mbps and should be around 30-50Mbps). And all speed and duplex has been accounted for.
I am trying to understand the stats that I see for the 802.11 MAC counters I under the Wireless APs.on the controller.
That screenshot is attached. I see high numbers for the following areas:
- Tx Failed Count
- RTS Failure Count
- FCS Error Count
what these mean and what could cause this? Maybe these are normal and not a concern.

basic question regarding the switchports on the rear of the 2106 controller. How do I configure them for use? I'm using port 1 as my uplink to a trunk port on an ASA and my network traffic to the management interface and guest vlans is all working as expected, but when I plug anything into any of the other ports, they get no addresses from my dhcp server (the ASA). I see nowhere to configure which vlan to tie the ports to or anything. I suppose I'm more used to a catalyst or ASA where I can just pick the ports and vlans (or trunks) I want to attach them to. [code] Again, all of the existing network functionality (private and guest network) is all functioning fine so I'm pretty confident I have the above configured correctly, I just cant make any progress on the WLC ports 2 - 8.

4 x AIR-LAP1131G-E-K9 (IOS = 12.4(21a)JHB1)
All configued ok with 2 SSID's associated to 2 VLANS all operates as expected.However every few 2 to 12 hours the WLC crashes, locks up.Unabale to contact via telnet or browser, will not respond to ping.The LAPs remain up but the WLANS go off air etcOnly a physical restart of the WLC will bring it back.

I am new to configuring WLC's. Our small business (5-15 wireless devices + 15ish wired) is trying to use a hand-me-down WLC and AP for our office wifi. We have a WLC 2106 directly connected to a 1231G-A-K9 via the WLC's port 8 POE. I am aware Cisco does not recommend this method, but we do not have a configurable switch at our disposal. We do not need separate VLAN's therefore I have left everything untagged. The AP has a static IP setup to allow communication to the WLC since it did not pull one from the WLC.
The AP is getting the correct network information and is showing up on the WLC monitoring page. I am able to connect to the new wireless network and able to ping between devices connected to the same AP. Now here is my question/issue. I cannot get communication from the WLC/AP to the rest of our network via an unconfigurable Netgear switch (FS605v3). After connecting an open switch port from the Netgear switch to port 4 on the WLC, I am lost. I tried giving port 4 on the WLC an address on the office network, but I receive an error stating "the IP information conflicts with another device".
Here is what I have setup on WLC
Virtual - 1.1.1.1
MNG IP-192.168.10.10
AP MNG Ip- 192.168.10.11
Subnet - /24
Gateway - 192.168.10.1
DHCP - 192.168.10.250
DNS - 192.168.10.250
Static Address on the AP's fa0-192.168.10.15
Attempted port 4 setup on WLC
VLAN identifier 0
IP- 192.168.10.25
Mask - /24
Gateway - 192.168.10.1
Port - 4
Our office network setup:
Subnet - /24
Gateway-192.168.10.1
DHCP - 192.168.10.250
DNS - 192.168.10.250

I have a question to migrate a customer from a 2106 controller to a 2504 controller. Can I use the configuration file with both controllers having the same version?
Or is there another way not having to do it again manually? The old configuration is OK, only the hardware is end of sale.

i have an issue with a 2106 WLC. We have a 44xx series WLC and had an issue with Apple devices: they could not print from wireless. The workaround in the 44xx series WLC was that we have enabled Unicast in the Access Point Multicast mode (configued under Controller/General).
The issue now is that the 2106 wlc does not have unicast in AP multicast mode.

I'm using the 2106 in one environment with ROOT AP and MESH AP and when i put these in the Bridge mode, when one client connects to them it isn't working well, sometimes i can reach the client and sometimes not.
I tried it with an Access Point that connect with the ROOT AP or MESH AP and will do an ethernet bridging with another wired client (camera), what happens is very strange because sometimes i can reach the bridge client and sometimes i can reach the Access Point that is doing the bridge. I can't access the two clients at the same time. In this situation i lose the images from camera when i have access to the Access Point and when i get the images from camera i lost access with the Access Point.
When i put the ROOT AP in the H-REAP mode Local Switching with AP 1142 or AP1552, the clients connects well and the bridge mode in the another access point works without problem, when i put the H-REAP in Central Switching i have the same problem.
I'm using in the 2106 WLC the version 7.0.240.0.

I would like to get webauth bundle sample to create custom page for our AP controllers but I'm unable to find the sample .tar within the WCS itself.Some other WCS manuals has references in them that says there should be link to download sample from WCS but clearly 2106 hasn't got one.There's one in download section "webauth bundle 1.0.2.zip" but this is for registered partners and costumers, we are not registered as partners and cannot download the sample ourselves.

I am trying to lab something up and I believe I am doing something incorrectly. My management VLAN works fine, the AP on port 7 finds the controller fine, but my VLAN 80 doesn't seem to be mapped to port 2. I mapped a test WLAN to the VLAN, and setup a DHCP scope, and a client can get on the WLAN, acquire an IP address, etc. I thought I coudl then map that VLAN (80) to port 2 and have it go out a cable modem. Doesn't seem to be working that way, however.

I'm setting up a 2106 controller with 3 APs.
When I connect the APs to a port on our 3550 switch, the AP gets an IP and associates with the 2106 controller. I can ping the AP from a wired PC and associate a wireless client to it. When I connect them to the PoE ports that are on the controller, it gets an IP and associates with the controller but, I cannot ping it from a wired PC or wireless client but, I can associate a wireless client to it.
The AP manager and Management interfaces, under PHYSICAL OPERATION are configured for port 1, which is the port that connects the Controller to the rest of the network. Since the whole network is using VLAN 1, I set the VLANs for the Management interface and AP interface to 0, untagged. I noticed when I set the AP manager interface to 1 I get the same results.
