Cisco Wireless :: Replace WLC2504 To WLC5508 Without Service Interruptions?

Mar 12, 2013

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?

Cisco Firewall :: Interruptions Of Connection Through ASA 5520

Dec 12, 2012

I have a problem with the connections to the remote webservice passing through ASA 5520 firewall. Connections are usually  interrupted in perod of half an hour in every few days.
This ASA 5520 firewall is only one firewall in a path to the remote webservice.
During the interruption I find the logs:
UTC: %ASA--4-419002: Duplicate TCP SYN from dmz1:x.x.x.x/.... to outside:y.y.y.y/p with different initial sequence number
Teardown TCP connection 28309406 for outside:y.y.y.y/p to dmz1:x.x.x.x/.... duration 0:00:30 bytes 0 SYN Timeout
How I could find root cause? Could it be solution implemetation of TCP State Bypass?

Cisco Wireless :: How To Activate Mesh Software In WLC2504

Nov 9, 2011

I have two Wireless LAN Controllers 2504 and 8 APs 3502e. The WLCs are running software version The problem is that I don't have the mesh option to configure indoor mesh inside the controller. In chapter 9 of Wireless LAN Controller Configuration Guide, Release says that I have to go to Wireless Menu and select the AP. When I am inside the AP general page, the guide says I have to go to the Mesh tab, but that tab doesn't appear in the controller GUI. Do I have to use another image in the controller? Or do you have to use an special mesh code or something like that? Because in the download page of the controller it only appears the, two more new versions but there is nothing about mesh image.

Cisco Wireless :: WLC2504 - Configure Clients To Access 802.1x?

Jul 4, 2012

configured Cisco 2504 WLC with 1142 Aps...  Guest wireless works fine
for the staff wireless I wanted to authenticate with 802.1x & Radius. So configured an external Radius server (Imprivata) and configured the 2504 Radius options for the extenal server.( Layer 2:  WPA2-AES & Auth Key Mgmt:  802.1x )
When I connect a client to this wireless, the authentication fails, I wonder whether it is because of the client side settings..
Which trusted Root Certification Authorities need to be checked?

Cisco Wireless :: WLC5508 - Backup WLC Across A WAN?

Jan 29, 2013

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

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)

Cisco :: Unable To Connect WLC2504 To 2960?

Mar 13, 2012

setting up a 2504 on a 2960 switch.  The management interface is up and pingable, and from the WLC we can ping vlan 20 (our wireless client vlan) gateway.  However, when we create the vlan20 interface on the WLC, give it a valid address and assign it to a port, we can no longer ping the vlan 20 gateway from the wlc, nor can we ping the vlan20 interface from a PC.  I’m told the 2960’s don’t do dot1q trunking…

Cisco Wireless :: Several Remote Sites And Centralized WLC5508

Nov 8, 2011

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.

Cisco Wireless :: WLC5508 Link To Switch Core Down?

If that might be the cause, is it possible to get WLC to 100 Mbps?

Cisco Wireless :: Minimal WLC5508 CLI Configuration To Access GUI?

Sep 8, 2010

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:

(Cisco Controller) show>interface detailed management
Interface Name................................... managementMAC Address...................................... IP Address....................................... Netmask.......................................

Cisco Wireless :: WLC5508 - Ipad2 Can't Join Wi-Fi Using Wpa2 AES

Apr 12, 2012

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.

Cisco Wireless :: Configure 802.11n On WLC4404 Or WLC5508 In 2.4Ghz?

Aug 15, 2012

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
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
AP tested in different variants - open system and WPA2+AES.
