Cisco Wireless :: WLC5508 VoIP Connectivity Is Broken
Jun 22, 2012
I have a WLC5508 and 25 LAP 1041. I use two wifi, one with RADIUS for data and other with wpa-psk for voip. The problem is the voip conectivity is broken.How can i improve the handover?
I have been experiencing drops in my wired internet connection and a google search brought me to your forums.It seems to disconnect more often either during a call on my voip phone (a snom) or shortly after - as if a surge of usage makes it drop out?
Currently we have 20 remote sites, each with 2-5 AP's each. They all connect back to our Main Data Site in the US and register on a single WLC5508.
We do not have a backup WLC, but are looking to purchase one. What I would like to know is, are there any problems with the secondary WLC being installed in our Main Data Site in Europe? These two main sites are connected via a 10M MPLS WAN.
So all the remote sites could still connect to the WLC in the US, but in the event of a WLC failure in the US, they would need to fail over to the site in Europe
I'm using WLC5508 /w 7.0..My client do not get its IP. Status shown "DHCP_REQD".I found in (Cisco Live) Troubleshooting Wireless LANs with Centralized Controllers This related with Enable/Disable DHCP Proxy checkbox. I solved. with Enabling this.But,
1) Why this box have been working correctly for longtime? No one did diable/enable this feature on my box.
2) I guest, ver7.0 Disables this chechbox by default. Or not? I also have others two 7.2 boxes. Those are all Enabled.
I have some problem about dhcp via VMware 7.1. My client connect the wifi and get ip address well, then, i turn on VMware (inside my computer) and set as the bridge mode. I found that my VM cannot get the ip-address from dhcp server and I using WLC5508 version 7.2. I try to connect via Switch, my VM get the ip address well.
looking at doing the site survey before detailed implementation. we plan to use a wlc5508, AP3602, a good tripod/stand, PoE switch and AirMagnet to conduct the site survey. i'm inclined to use a single AP and just a guest SSID and let AirMagnet merge the readings on where i 'locate' the AP (on 1 VLAN)
A customer have a bad coverage in a corner of his branch office. He like to add a mesh AP (MAP) in the near of that corner.
I checked allready the documention about Mesh but i'm not sure if Flexconnect and Mesh works togheter. This MAP is in a branch office and the WLC is in the head quarter therefore he likes to uses Flexconnect togheter with Mesh.
I have a customer who is going to deploy a WLC HA AP SSO setup. I have recommended them to have 4 Gigabit SFP modules in each WLC5508.The customer now asks if it is possible to only have one or two SFP modules in the standby unit ? As he says it is properly not going to go in service one time within the next five years if he is unlucky.
We have five cisco WLC 5508 and one WCS .The WLC is running on 7.0.116.0 version at present but we want to upgrade it to 7.4.100.0 but on cisco site at download location , the below thing is mentioned...
WLC Version 7.4.100.0 will need Prime Infrastructure Version 1.3 to be managed, Version 1.3 is not yet available to download at this point of time
Access Point Model----Cisco 3501i Series
So i want to know, can i upgrade it to this version when we are having the WCS in our network ?
I have tried to upgrade from 2.0.2.1 ever since 2.0.3.3 was released back in July. The firmware image file has remained the same, so I don't think they've ever changed it from the original July release.The download and installation go fine, I even reset to factory defaults. The problem is that several menu selections are broken, and don't allow you to save your choices, i.e, you can't even rename your SSID. You can type it in a Apply, but the fields just reset. I figured this would be fixed with a minor update to 2.0.3.3, but we are now several months since original release and nothing has changed. I have tried this firmware at least three times now. I have not bothered lately, because I don't want to waste another 30 minutes trying it and reverting back to 2.0.2.1 if this newest firmware is not going to work.
I have a new wireless router (new network, entirely). I used to get intermittent "network access denied" messages. Now, I get intermittent connectivity loss: "No internet access." I typically just right click and troubleshoot. The problem is solved and I get the following message: "Problem with wireless adapter or access point." Once fixed, things go on well for a random time (never more then a day). Then, however, they just fall apart.
In one week I need to import the config from my 4404 WLC to my new 5508, then I just want to change the mgnt IP address of the 5508 and then bring it into the same mobility group.How do I import the config when the 5508 is straight out of the box?
I have WLC 5508 with 6.0 software and kept in main office and 10 sites are connected . I created Group and hreap for the sites AP.Now customer wants the secondary WLC to keep on one another site. And the customer is asking all the configuration like ap group and all should come to secondary wlc automatically . In future also if he create any new group in primary it should come in secondary wlc.And if primary goes down the secondary should controll all the sites and when comes up primary should taken care.Active standbye mode.
I have been asked to setup wireless and we have purchased WLC 5508 and 1142 APs.We have several remote sites and a centralized WLC. The requirement are to have a common SSID (Corporate) advertised across all the remote sites and have that SSID locally switched, and have another two SSID Guest and Mobile tunneled back to the central site (WLC).I want all the wireless (Corporate) clients to use the same subnet as the wired clients at each remote site, the IP assigment will be done by a DHCP server at the central site. The Guest and Mobile users will use a common subnet each across all the site and this will also be handled by the DHCP server at the central site.
I have enabled H-REAP with Centralized Authentication and Local switching but I'm not sure about the second part which is to have a common SSID (Corporate) across the remote sites and localy switched whilst having the other two SSIDs tunneled back to the WLC. Cisco TAC told me to configure dynamic interfaces for each of the remote site but then he said I still wouldn't be able to switch the Corporate traffic localy if I use a different subnet to the wired subnet for the wireless clients.
My problem ist that i have 4 air-cap-1552e APs witch are powerde trugh Power Injectors. They worked fine for a few days but then the controller (7.2.111.3) lose connection to them. Right now i have only one Joined AP. The other 3 are status not joined. I can Ping all 4 Aps and wifi clients are connected through them.
I tried to implement WLC5508 in my network but when I came to connect it to the switch core which is a Catalyst 4000 the link didn't get up. This switch module is a fastethernet, I wonder if that might be the problem since I also tried connecting my laptop to the WLC and the link got up.
If that might be the cause, is it possible to get WLC to 100 Mbps?
I have on my desk a WLC-5508 that I need to setup to ship to a remote location. Normally we configure 4402 model and this model/version appears to be much different. I am trying to configure just enough via the command line to access the GUI via a laptop directly connected to the device. I’ve gone through the Wizard Configuration Tool where you set the hostname, admin account, and management interface (among other things). We use LAG and tagged VLAN on the management interface. I’ve been told in the past this is how we configured the 4402 models via laptop directly connected once the GUI is accessible, but with LAG enabled I don’t understand how a laptop could communicate via trunk, so I've disabled LAG and set the VLAN to untagged. In either case the laptop does not communicate with the WLC. Skipping ahead to my current setup I see the following information via the CLI:
we have a cisco WLC 5508 on which few SSIDs are configured, and two kinds of APs: AIR-LAP1142N-E-K9 and converted AIR-AP1141N-E-K9.
When in WLAN settings we leave WPA2 policy and AES encryption, iPads2 can connect without any problems to AIR-LAP1142N-E-K9, but there is no connection to converted AIR-AP1141N-E-K9. MacBooks, iPhones are connecting without questions.
When we set WPA2+TKIP everything is cool, but other Apple devices can't rich 802.11n speeds((
With only WPA2+AES or both WPA2+AES+TKIP enabled on a WLAN the WLC gets such messages :
Decrypt errors occurred for client xx:xx:xx:xx:xx:xx using WPA2 key on 802.11b/g interface of AP xx:xx:xx:xx:xx:xx
But I know that it can happen when you offer funny encryption combinations that client doesn't like (wpa1+aes, wpa2+tkip). But the advise to try to only enable wpa2/aes for some reason doesn't work.
how to set up support 802.11n on WLC4404 or WLC5508 in the 2.4Ghz? WLC4404 supports 802.11n? or support this protocol only in the brochures? I spent a few days, but did not get the result. I'm connected at speeds 65/130Mbit, but the real speed tests never exceeded 45Mbit. The AP from the test laptop is 7-10 meters.I tested the laptops with a Linksys AP E1200-EE ( 40Mhz, FastEthernet uplink port...)and received nearly 100Mbit!
At WLC5508 able to connect at speeds 150/300Mbit/c but only in the 5GHz band, but real speed tests never exceeded 70Mbit.In 2.4Ghz range I connected at speeds of 130/144Mbit/c, but actual measurements showed no more than the 45Mbit.
All tested with iperf and with site speedtest.net. iperf -w64K -s iperf -w64K -i 2 -t 300 -c x.x.x.x
Laptops: Asus (Atheros AR9002WB-1NG) and Sony (Advanced-N 6230).
My tests AP: 3501I-E and 1252AG-A SW on WLC5508 7.2.110.0
AP tested in different variants - open system and WPA2+AES.
I have two WLC5508 controllers running 7.0.230.0, which having the two of them probably is inconsequential because all the APs are added to only one controller. The problem I'm facing is that I have several LAP1552E's deployed throughout my facility, and I have several that are doing Ethernet bridging to some Cisco switches using G0. In this, I have a PC at the end of one of these switches, and using Iperf and PingPlotter to get some metrics, and what I'm seeing is >400ms latency with <3 Mbit throughput to the PC. On the 802.11a radios I have 18 Mbit set as mandatory, with everything below disabled and everything above Supported, with all MCS indexes under 802.11n enabled.
My channel is set to 161 with a 40 MHz channel-width, and a power of 3 configured.After many days of trying different power settings, channel settings, and such, I can't get better results than above and my channel utilization stays > 75% at all times. I do have video cameras attached to the other bridges switches, and have video QoS set to Bronze and the cameras configured to ~ 1 Mbit bandwidth maximum. Also, average RAP-MAP distance is ~ 1100 ft and average MAP-MAP distance is 400 ft, with the longest RAP-MAP being 1400 ft and MAP-MAP distance being 875 ft.
I try to configure an AP1131 as OfficeExtend but unfortunately I receive the following message from the debug command on the WLC5508: (Cisco Controller)

I have the attached diagram and I followed the instructions from another posts / forum cases and the Apple TV is still not working.
My questions are:
1.-The WLC controller and AP must be in the same subnet?. This is not my case, the AP 3500 is operating in a remote location and I have a centralized WLC 5508. 2.- I already configured the Controller --- > General --- > Broadcast forwarding (enable) + AP Multicast Mode (Multicast / IP: 239.20.226.197). 3.-I already configured the Controller --- > Multicast ---- > Enable Global Multicast Mode (selected) + Enable IGMP Snooping (selected) + Enable MLD Snooping (selected). Please see the attachment. 4.-Do I have to configure something in the Mobility Management --- > Multicast Messaging --- > (Enable Multicast Messaging + Local Group Multicast IP Address) ?????
The Apple TV Device and Ipad are authenticated in the ISE using certificates with no issues and both got IP's from the DHCP for the WLAN Vlan assigned to the SSID activated (see pictures attached).
I have a TAC case open, but it doesn't seem to be making any progress.I upgraded my 5508 controller from 7.2.111.3 up to 7.4.100.0..Most of my APs are fine. 3500s, 1100s etc.except for 602i APs. The APs associate, they update software etc, but they won't broadcast the WLAN.An interesting thing, on the 602 AP, in the log, I see this:*Mar 06 15:08:12.667: SSID remote, WLAN Profile Name: RemoteOEAP, added to the slot[0], disabled..So the AP is definately talking to the WLC and being pushed the correct WLAN profile.On the controller, the AP shows the the Admin status of the radios is showing DOWN, but the Admin status on the AP itself shows UP
I've done a factory reset on the APs to no avail. I have a 2504 WLC as well that i'm in the process of implementing in a DMZ specificially for these APs, and for testing purposes, I associated the 602 Ap to that WLC as well. This one is running 7.4.100.0 too, same results. It would appear to be a problem with this version of software?
I have been using WAP4401N for almost a year in our office and I’m very happy of this device, never had any problem. So I bought 3 new ones for our customer which supposed to work in configuration below:
Everything was working perfectly fine to the moment than bridge was broken. I can get access to all AP (obviously when connected to proper part of network) however not able to ping from AP2 -> AP1 or opposite so basically no link between AP1 and AP2. After reboot everything is working fine to next time (happens twice in two days). When I go to System Performance can see Connection is enabled but doesn’t work.
I upgraded firmware to latest version (2.0.5.3) but haven’t worked. When I’ve done some research found many users having similar problem with this device and basically they recommend to don’t buy. Unfortunately this is not an option for me as I’ve already purchased them.
My laptop's wireless network adapter is not working Eventually I managed to re install the driver but that did absolutely nothing and now it won't connect unless I have the ethernet cable plugged in. It also no longer will tell me there is a problem with the adapter, it just refuses to bring up any wireless connections. My laptop is a Dell N5110.
I want to start implementing a small outdoor mesh network of 3 APs Aironet 1550 in order to grow afterward with more APs. Is there any way to configure those 3 APs in an outdoor mesh configuration (for example, only one RAP and two MAPs) without a Wireless LAN Controller or I have to have at least, one WLC? My idea is to have a WLC 5508, but at the very beginning I don't know if my budget is gonna allow me to cost the WLC.
In an enviroment with WCS and a WLC5508 with 40 AP's (WAPs are either 1262's and 1252's), I have noticed that the bulk of users are infact operating on 802.11g although most operating notebooks are running 802.11n capable NICs (including my own laptops NIC - but yet when I connect I connect at 54Mbps.). Only a small portion of registered clients are using 802.11n. All my WAPs have both radios enabled?My question is how does a client notebook select a "prefered" band of 802.11n. I know in some cases the wireless NICs themselves have an option to select the "Prefered Band", but there are many notebooks out there that dont have this option. What would make a client connect at 802.11n over 802.11g? Who makes that call ?
We're running two 5508 WLCs running 7.0.235.3 pushing out 7 WLANs. They are both live. Each WLC is connected to the same stack of 3750G running 12.2(44)SE6 via Etherchannels.I'm getting tons of MAC flapping errors similar to this:9373213: Feb 19 10:53:54.564 CST: %SW_MATM-4-MACFLAP_NOTIF: Host 843a.4b3c.4cec in vlan 752 is flapping between port Po12 and port Po11Each portchannel consists of ports on each of the two switches in the 3750 stack. Only VLAN 752 shows the flapping activity. LAG is enabled on the each of the WLCs. The portchannel and interface configs are identical, minus the channel-group command of course.Maybe completely unrelated....looking at CDP neighbors from the switch is incorrect:
WLC1 Gig 2/0/44 157 H AIR-CT550 Gig 0/0/1 WLC1 Gig 1/0/21 157 H AIR-CT550 Gig 0/0/2 WLC1 Gig 1/0/20 157 H AIR-CT550 Gig 0/0/3
how can i replace my wlc2504 to a WLC5508 without disconnecting everybody, i have 3 SSID, on different VLAN.. I want the WLC5508 to be the main WLC, so i can remove the 2504 from the network. On the WLC5508, it will be the same configuration of the 2504. Is there a procedure or a wiki on such operation?
