Cisco :: 2125 Wireless LAN Controller TX Power Configuration?
Aug 29, 2011
I have a Cisco 2125 Wireless Lan Controller and I have problem with hold coverage errors and I had tri different solutions with different antenna, the resume is:The antena gain 10*0,5 Dbi(Using a 5 Dbi antenna or 10 Dbi antenna) with Tx power 1 and the antenna gain 20*0,5 Dbi (using 10Dbi antenna) with Tx power 3 the coverage is the same.
If I try the configuration 20*0,5 gain antenna and Tx power 1 the controller show me one error and the controller don't permit this configuration. Why don't permit this configuration?
I am looking to configure a wired and wireless guest network. I have industrial barcode scanners that connect to one SSID and then there is the business network on the office SSID (no vlan seperation for these devices just different SSIDs). There is not really a need to seperate the business network from the scanners in any case. However, there are needs for a guest network and this needs to be seperated. At the bare minumum I would like to have the wireless guest network. Here is what I have: 2125 Wireless LAN controller managing 18 LAPs (1 indoor and 17 outdoors)Cisco Cat 2950 switches (2 x 24 port and soon to be replaced with 2 x 48 port 2960's with 802.1x capability) Sonicwall TZ210 firewallOne existing wired and trunked vlan for PLC infrastructure. One ESXi hosting Windows server guests (soon to be 2 with vMotion) The reason for the wired guest access network is tp prevent anyone from plugging into the wall jack in the office with thier home laptops or anyone else from being on the same subnet as our domain machines. Granted they would be unathenticaed but there would be no layer 2 seperation and that is what I think would be best.
How would I go about doing this on the wireless controller without an anchor controller just using my existing hardware? I would like to have the Guest SSID only availible in the front office. Is it possible to offer a guest network while still servicing the business network SSID on the same access point? Then might I be able to have the guest network be treated as it should at the controller? However this might present another issue altogether as the guest traffic will be over the same wire as the business SSID until it hits the controller for management.
We have cisco wlc 2125 with 13 AP 1131g. All works good. But after power failure one AP can not join to controller, only reset work to recover connection AP to WLC. Additionally, we don't have access to rs-232 port on AP. In this moment on WLC we can see DISCOVERY request from AP and response from WLC to AP, but AP don't send JOIN to controller.
A customer has wireless LAN controller with version 4.2.205.0 and i want to upgrade it to version 7.do i need to upgrade the controller to intermediate version or i cant directly upgrade it.
I will migrate a Cisco WLAN Controller 2125 to 2504,So I have one question?I need to make all configuration into the new Wlan Controller or I can migrate with one tool or something else?
I have this issue regarding the 1131 Access Points. These access points were fat access points from the factory and were applied with LAP ios so that they can join our controller. We have 2 controllers 5108 for Internal network office use and a seperate 2125 for Guest internet both these are physically seperate networks. These AP's have been working fine since say like 8-9 months and suddenly they started giving problems. The status light keeps changing colour and the AP does not join the controller 2125. Whenever i am connecting this ap to our internal network it joins the controller 5508 and works fine but somehow does not register with our 2125 guest controller. This issue is being faced by one of our client. Could this be an issue due to the ap being loaded with lap ios or does it have anything to do with the different software version fo the controllers as i could not find any things regarding this.
A few months ago we upgraded our warehouse from 1242 APs to 3502E APs. We changed 16 units, all in the same building. When we came in the next day we found out that they were all on channel 1 at their lowest power level. The WLC was set for auto negotiate for power and channel but for some reason it did not work. We had successfully changed they rest of the factory with the auto feature enabled but for some reason, the warehouse did not work properly. All APs have the same IOS and are they same model. We have WiSMs mounted in a 6509 chassis as our WLC.
We have some 1242 LAPs in a two 5508 controller setup working fine. All LAP are configured to obtain address from DHCP. After first join we usually change some configs like HOSTNAME, AP GROUP, PRIMARY AND SECONDARY WLC. After a software restart or a complete power off/power on the LAPs joins the primary controller and all configuration still there. We now add a 1142 LAP and is does not retain the configuration after a power off/power on cycle, but after a software restart there is no problem. The only way to retain the config is setting the AP with a static IP address.
We use WLC 7.0.116 and we see no errors in the LAP console.
So we have a Cisco 5508 controller that is managing 15 AP's in one of our buildings.I am running 2 wlans, one is internal access via (wpa) radius, peap and domain login...that works well now
The other is a guest lan, that is only allowed to surf the web.
The question from our security group, is there a way to restrict wireless access to ONLY a corporate approved list of devices.
As it stands right now, we only support Blackberry's as our mobility device. All local data is encrypted. The issue here is our testing shows that with an Iphone (not approved) it is very easy to connect to the WPA network if a user knows how to enter in their domain credentials. From there they can browse our internal web servers and download corporate data to a non approved, non encrypted device such as the iphone.
Any link that will give configuration examples of a wireles anchor config with one controller in a DMZ. I have tried this on my own and have some problems in my test enviorment. I believe my issues were with the firewall but not exactly sure.
I'm looking for a document that states the best practices for WLC configurations (Management/Security/AP's..etc). I can currently only find the following document:URL
But this document has last been updated in 2008, in a few days that's almost 5 years ago, and we all know how quickly technology is evolving. 10Gb wireless is around the corner, with 1GB starting to go production now. This document also mentions the 4400 (which is end of life).
I have to install a wireless mesh network shortly using Cisco 1552 APs. This will be controller based using 5508 controllers. The controllers currently have some 1262 APs configured in a mesh and bridging configuration so happy that it all basically works. My question is - what is the "config mesh range' command doing on the controller ( or setting the Range(RootAP to MeshAP) setting on the controller mesh GUI. The default setting is 12000feet and I have left it at default at present. Just interested in what this is used for - I assume it alters the mesh protocol parameters somehow ( or the RF parameters perhaps ) as it suggests in the guide that mesh APs will reboot following this command being changed.
I am actually working in configuring a wireless controller 2504 integrated a windows 2008 server as radius server for authenticating the network users registered in a windows active directory database. The Radius server is a Windows 2008 Server with the rol of Network Policy Server.
I have been following a pair of documents in Internet, but it doesn't work yet.
Which authentication method should i use?...the Windows 2008 NPS doesn't work wtih LEAP, should i use PEAP or there is an another recomendation to authenticate the windows active directory users?
configuration tested working between a cisco wireless controller and Windows 2008 NPS as Radius Server for authenticating the windows network users.
We have 5508 controller (redundant) & would like to configure Staff vlan to get authenticate with active directory.i am new to the controller device & want to configure controller with active directory (windows 2012).
5508 controller (Active & Standby) with 48 Access Point.(configuration Done) Guest Vlan (only for internet Access) controller based web authentication configured.
Staff Vlan ( inside & outside ). Need to configure with LDAP authentication?
I am configuring a WLC2125 which I'll install in a customer's building to convert AP1131 to LWAPP currently it is out of the network as a lab but the problem is that I could convert an AP to LWAPP but it does not associates to the WLC, this is the log it generates:
*Apr 08 21:07:13.801: %LWAPP-3-RD_ERR9: spam_lrad.c:8375 APs 00:18:74:4b:ed:e0 country code changed from (MX ) to (US ) *Apr 08 21:07:13.800: %LWAPP-3-RD_ERR8: spam_lrad.c:8056 Country code (MX ) not configured for AP 00:18:74:4b:ed:e0
I need to take the backup of configuration file for WLAN Controller 4420, I tried all the possibilities given in the documentation but the backup fails, I have main confusion with the file name to be backedup, i am not able to findout the configuration filename any where even when i use CLI?
I have 2 5508 controllers in a mobility group. Any good way to keep the configuration between the 2 controllers synched up?
I thought about copying the config from my primary controller to the secondary controller, but I would think there is a more elegant way to make this happen.
I try to make custom web-auth bundle for WLC 2125. User authentication from this custom page work fine, but any error messages about wrong login/pass not work.
Is this supported function for custom pages? If yes, could you result a working html-code?
I have WLC 2125 on version 6.0.182.0 and AP's on version 12.4(21a)JA.I also have a load more AP's (newones) 1041's with IOS version 15.2.
So i have to upgrade my WLC because the newones are not compatable with the old WLC version.What will happen to the old AP's ?I was told they will automatically update the IOS version.These AP's (oldones) are not on site, they are in a differnet LAN.
I have cisco wlc 2125 and external web autherthation was configured on it. When user disable the java script in browser cisco wlc do not redirect on my external page instead of wlc show page http://1.1.1.1/login.html with cisco logo. How can i resolve this problem? How to configure wlc redirect to external web auth site with disabled java in users browser?
I have a ACL applied on a WLAN on a 2125 controller. I cannot get the older Cisco IPSec (Version 5.0.05.0290) client to work through the ACL and through the WLAN onto it's destination. When the Cisco IPSec client is on another unrestricted WLAN, it works. I have allowed TCP/UDP 500, 4500, TCP 10000 both directions and it fails. I can see the denys counters incrementing but cannot figure out what is being blocked.
I have a 2125 WLC. I have some 1242 Access Point registered to the WLC. The problem is that the handheld connects to the WLC but sometimes it shows that it has lost wireless signal. Users say that this happens when they go from one site to another. I go to that specific site with my AirMagnet tool and it shows full signal. The customer is saying that WLC is not working with roaming properly.
I have a Cisco 1841 Router with ADVANCE IPSERVICE IOS .The said router does not safe config, even after saving the config? As soon as the power cycled all the config will be lost? what can be done to correct this ?
I would like to know if the power the Nexus 7K allocates per module is configurable?For example, we are only using the 8 didicated ports on our N7K-M132XP-12 card. The Nexus budgets 750W for the module, but given that we will only ever use 8 of the 32 ports we would like to allocate the remaining power elsewhere.
Any issues are reported while configuring power stack ? We did several times with 12.2.58SE1 and SE2, sometimes the power stack is created automatically, sometimes needs to be configured manually. Looks like the behavior is not the same. Maybe it depends on the number/type of switches and number/type of power supplies.
When I try to import configuration from the controller 4400 to my WCS it gives the following message:
Status Refresh succeeded but some records were dropped because their key fields failed validations.
When i see the config in the WCS, all of my light access points are not on it. I check for the logs and this is What I get: (its a lot of info, so I am putting an example!)
I keep getting alerts from our WCS stating that our 1252s are drawing low power. Now I am aware that they require enhanced PoE (up to 20W) but as we only have standard PoE in that building we purchased the 1252 series power injectors to go with them.
However, even with the correct power injectors the WCS still reports the draws low power error.
Is this a bug? Running WCS 7.0.172 at the moment.
Forgot to say we are using the PWR-INJ4 and the injector status is enabled and you see the injector MAC address when you drill in to the AP status.
I'm having problem joining a AP802 access-point in a Cisco 887VAM-W router to a WLC2125 running 7.0.116.0. I get the following messages pasted below from the AP console. The AP connects to the WLC over a EZVpn tunnel with a ASA on the other end, and can't see any error messages there. [code]
I am quite new to WCS and preparing a demo for a client. I am also using WLC2125 with LAP1252s for this setup. Is it possible to modify the shape of the heatmaps of the APs? I know how to regulate TX power of the radios and all works great but how can I controll RF leakage outside the perimiter of the building? Is it possible to controll the RF so that it will not be going outside and same time giving a good coverage inside?
Current environment is Cisco 2125 WLC managing ~12 3502E AP's for a single location. Client is looking to provide HA for the single 2125 WLC. With the 2125 now EO-Sale is it possible to go with one additional 2504 WLC and leverage the existing 2125 or would it require going with just (2) 2504's?
