Cisco Wireless :: EIGRP Routing Through LAN Controller 5508
Jul 15, 2012
Fairly intriguing project I am working on that requires some interesting out of the box thinking. I have a 5508 Wireless LAN Controller. This is still preliminary design so the version of code can be whatever. The 5508 has Cisco 1552 Wireless MESH Access Points. Connecting to the MESH Access Points are Cisco 1262 MESH APs which can I am hoping can be bridged to utilize the ether port to connect to a Layer 3 switch. This layer 3 switch, I need to run EIGRP so that the network behind it can be separate from the MESH network and route accordingly. I know it sounds odd but was hoping for some feedback as to if this is even possible. Basically, the network is extremely mobile and trying to cut down on the broadcast domain and segment this out a bit.
I know that the 3600 series APs are not supported on the 4404 WLC. However, would the following scenario be supported? I would like to use the 4404 (software rel. 7.0) as a guest anchor with a 5508 (software release 7.2) as the foreign controller supporting series 3600 APs. I ask because the APs do not need to join the guest anchor.
We have a customer that have 2 5508 as primary and backup controller and a 4400 as an anchor controller. We plan to upgrade the 5508 to 7.3.112.0 and the 4400 is already 7.0.116.0. Will there be any issue if the anchor controller is not the same code as the foreign controller? Do I also have to upgrade the acnhor controller to 7.0.240.0?
I have a 5508 controller at our headquarters and am installing some 3502 AP's at a remote branch. Unfortunatly, the remote branch has a different Vlan setup for some reason and the vlan that is used for the WLC (90) is designated for telephony at this branch. Can I put the AP's on a different VLAN (10) without having any issues? I will still use DHCP option 43 to point them back to the controller. Below are the configs for the WLC interfaces and what I am proposing for the AP interfaces:
Cisco 5508 Series Wireless Controller for up to 100 APs 802.11a/g/n Ctrlr-based AP w/CleanAir; Ext Ant; E Reg Domain..For Mobility i want to settup the device such that the SSID would be the same with thesame security key and in different subnet.
I use WLC 5508 (ver 7.0.116.0) with aironet 1140. I need to connect my APs to different controller .After log in via ssh to AP i am trying to do:
capwap ap controller ip add x.x.x.x reset
But after reload, AP is still joined to the old WLC. So another idea was to log to that WLC and put:
config ap primary-base WLC2 AP_NAME x.x.x.x
and after that:
config ap reset AP_NAME
But still nothing, it's joined to another controller although "show ap client config" shows that primary-base switch is x.x.x.x ?How can i force it to join to other controller?
We are looking to upgrade our 5508 wireless controller from 7.0.98.0 to 7.0.220.0. Reason being, we have experienced a lot of access points disassociating from the controller as well as client authentication issues. Upgraded from 7.0.98.0 to 7.0.220.0 and any issues during the upgrade or after the upgrade?
We have a WLC (5508) in our main office in Brisbane that is hosting two WLANs. One provides wireless access to our internal network and the second provides wireless guest access. The guest WLAN is anchored to a controller sitting in the DMZ at our Data Centre.
In the DMZ the anchor controller has a management interface and an interface in the DMZ for the wireless guest access. I am using the DHCP server on the anchor DMZ to provide IPs etc to wireless guest clients. The default gateway is 10.8.144.1 which is a VIP or a pair of firewalls.
Initially everything works fine. Guests connect to the guest network, have to authenticate via a web portal (Cisco ISE server) and then can go on an use the internet. Works perfectly until the firewalls fail over and the secondary firewall takes over the VIP address. All access to the internet is lost at that point. If I try to disconnect and then reconnect a wireless client it connects, as in it will get an IP address, but DNS resolution stops and I do not get redirected to the web auth portal. If the firewalls are failed back to the primary then everything works again, no issues. However, if I reboot the WLC while the secondary firewall has the VIP IP everything will work fine as it did on the primary. If the firewalls now fail over to the primary again everything goes to ****. Until either the firewalls are failed back or the anchor WLC is rebooted.
Initially I thought this was an issue on the firewall, but this doesn't appear to be the case. When the firewall fails over it sends out a gratuitous ARP advising of the change in MAC address for the 10.8.144.1 IP address. The WLC seems to update its ARP table because if I run the command "show arp switch" it has the 10.8.144.1 IP address with the MAC address of the active firewall. From the client perspective I have run a wireshark and captured packets on the wireless interface when trying to connect. The laptop is continuously send ARP requests for 10.8.144.1 but gets not reply. Without this the client cannot send an ethernet frame to the gateway and hence get to the DNS server and WEB portal. Internet access breaks. Doing a TCP dump on the active firewall shows it receiving and then sending a reply to the ARP request. It just never gets to the wireless client. Debugging ARP packets on the anchor WLC seems to indicate that the controller is receiving the ARP replies from the firewall. So I'm at a loss as to why things should break when the firewalls fail over.
I have a 3750 switch in the DMZ with SVI of 10.8.144.4. I thought I could get a work around where I would make this the default gateway. The theory being that this interface MAC address would never change. However I was wrong. Even with this IP set as the gateway address for the wireless clients I see the exact same bahaviour when the firewalls fail over. I can't explain it other than to say that the gratuitous ARP sent by the firewalls seems to kill the ability of ARP replies to be sent back to the wireless client.
Just replaced a 2106(ver 5.1) with a 5508 (ver.7.2)...Everything was OK.. AP's got on 5508 and we shut the 2106. (AP's are on L2 with controller)During some investigation of why new LAP's from a location via VPN/GRE don't show up in controller, i type the following command on 5508: test ap pmtu enable all....All AP's on 5508 is now in Not Joined state..Have powered up the old 2106 and put AP's on that .. This is OK ....Have rebooted/downgraded/upgraded the 5508 controller but with same result.....No AP's can join this controller (exept from a oeap600)
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.
I upgraded a controller yesterday 5508 it went from a low code version 6.x to 6.0.196.0 then to 7.0.116.0. However although all the access points joined code 6.0.196.0 they refused to join 7.0.116.0. The aps are all 1242s.
The country codes etc were all fine so I do not understand what was going on.

I have one controller 5508 that will hold 50 LAP 1262 and another Controller that will hold another 50 outdoor mesh access point 1552. Both controllers (not redundant) are at the HQ while the access points are distributed between HQ and 3 branches.
The requirements is to have the SAME 4 SSIDs on MESH and LAP each have a security type (, wep,wpa,dot1x...) on HQ and Branches. Now, in the HQ I don't think I will face a problem since the WLCs is on the same LAN, so 5 interface v lans will be configured one for the WLCs and access point and another 4 interface v lans for the 4 SSIDs.
Now, for the remote sites I need to create another vlan on the switch with DHCP and option 43 ..... for the access point to register with the controller.
But here, do I have to create another 4 interface v lans (4 different sub nets) that should be bidden to the SSID as in the HQ?
Or the Access point will encapsulate all the traffic including the client traffic? Note that I have outdoor mesh access point and Lightweight access point and the BW link between the HQ and branch is 100M.
Also Can I have roaming between the same SSID that broadcasted on MESH and LAP knowing that each have different controller.
[URL] I have one Controller 5508 is my Central Office and I have some Ap's working in local mode in my Central Office, additional I have more Ap's in a remote Office they're are working as H-REAP and I can handles across my WLC. Now my enterprise decided bouth another WLC and wants to deploy a active-passive scenario. This new Controller should manages all the AP's when the central WLC fails...
My questions are... I need to have the same ip addressing on both sites? or they can be different. I nedd to configure some on my Ap's that are working as local mode, for allow the secondary WLC manage them when mi central WLC fails
I received a 5508 WLC, that I wanted to configure as a guest anchor for our DMZ. I stepped through the console configuration. Now that the setup is complete, can I attach my laptop directly to the copper SFP, and access the WLC web portal? I gave my laptop an IP address, in the same subnet, but still can't connect to the portal, or ping the WLC IP address.
We have 3 5508 WLCs (A, B, & C) and several LAPs (1140, 3500, 3600). The APs learn the controllers IP addresses through DHCP Option 43. When we setup a new site we put the IP address of the controller we want the AP to join first. Lately, I've noticed that regardless of which WLC IP I put first when I setup Option 43 the LAPs are always joining a particular controller.
I have an AIR-AP1242AG-E-K9 which had c1240-k9w8-mx.124-21a.JA loaded, I followed the link below and upgraded with Cisco’s upgrade tool to c1240-rcvk9w8-mx with no problems at all, after the upgrade I could then see the LWAP on the 4402 controller and had it working a treat.Now the problems begin, I brought it into the office where we have 5508 controllers, plug in the LWAP into our management switch and boot it up I get an IP assigned from the DHCP server and the AP goes into discovery mode but never finds the controller.I have logged the boot process but this does not give much away, our other 1100 series AP’s boot fine,
[URL]
Console Boot Log. Xmodem file system is available. flashfs[0]: 9 files, 3 directories flashfs[0]: 0 orphaned files, 0 orphaned directories flashfs[0]: Total bytes: 15998976
[code]....
And that is where she sits and does nothing more, I have noticed the DNS problems but the other 1100 series LWAP’s boot up after show that same issue.
We just got a new 5508 wireless controller and the question we have is : can we get wireless users to authenticate to an Active Directory server to get access to the network? I know we can get the authentication done with an RSA server, but what about plain AD?
how to setup the 5508 Series LAN wireless controller. The online documentation are not details. What different between Service Interface IP and Management interface IP. The device IP is using what type service or management interface.
how an AP 3500 get to be registered in a controller 5508??, so, i have seen a lot of information of wireles deployment guide but i haven't understood yet how the process or flow is for getting the AP to be registered in a controller 5508, what exactly basic configuration must be done in a controller for doing it?
Our 5508 Wireless Controller will drop MAC addresses clean out of the system. Addresses that are in use everyday just disappear. It is not a limitation issue because we are adding iPads everyday. And it is not a daily occurance, but maybe once or twice a week. Everything has been updated and it is more of a hassle than anything, I am just trying to understand what is happening.
I am having some troubles with client roaming on a 5508 controller running firmware 7.3.101.0. As soon as a client roams outside the range of an AP they lose data flow and do not seem to transition to another AP for about 1 minute.This is a small network with 6 x AIRCAP3502E-N-K9 AP's (running in H-REAP mode) on the same floor and clients are a mix of HP notebooks, Mac Books, iMacs, iPads and iPhones. There are several seperate SSID's setup and the problem occurs on all. All are WPA2/AES with either a PSK or 802.1X. Both 2.4GHz and 5GHz radios are enabled with auto power and channel selection.
I have tried changing the roaming settings from default and also playing with the AP power settings to no avail.Is this normal behaviour or is there something I can do to improve the reconnection speed?
We faced one recent issue with WLC configuration behavior and explaining our observation and workaround we did.Requirement is to manage the WLC (5508 with 7.4 code) using two SNMP managers in different locations. Also these two Servers should use the same community string to manage WLC.
We were able to configure the SNMP community string for one server IP (to allow access) through GUIWhile trying to add another Server – IP with same community string – it didn’t allow As per the configuration guide, Controller can use only one IP address range to manage SNMP community. So we cannot configure the same community string to allow only two different server IP addresses [code] We currently configured the major subnet ( 10.x / 8 - two match both server addresses) and it works fineAlso when we tried 0.0.0.0 / 0.0.0.0 , it didn’t work (SNMP was failing)But this creates a security issue wherein anybody can poll the WLC.
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 am running 5508 wireless controllers. I pass along another agency's WLAN across my wireless network that is anchored to their older 4402 controller.
I wish to run the new 3600 series APs and am planning on migrating to NCS and the new 7.2 code.
I know that the older 4400 series controllers will not handle the newer 7.1 or 7.2 code. However, i still wish to maintain this anchor relatiosnhip with the older 4402 controller. I need to know if this will work or not.
We have a 5508 controller that manages AP's at approximately 20 branches - each branch has their own subnet. We have a single branch (subnet) with new 2602 AP's that will not register with the controller. All communications to this subnet appear normal and there are no ACL's in place between the AP's and the controller. The AP's are able to resolve the controller IP address via DNS and begin the registration process but then timeout. We have successfully installed 2602 AP's at other branch locations and they register with no problems - this is only a problem at a single branch. I've attached some debug messages below for a single AP (this is a production environment so I parsed un-necessary info) and also included the console messages from a different AP (the console messages on the AP's are the same). There are currently 9 AP's at this location and none of them will register.

I am setting up a WIFI network with a Cisco 5508 controller. I want to configure a first WIFI network (WIFI1) that will authenticate my business laptop based on the AD computer accounts and will access my corporate network.I want to setup a second WIFI network (WIFI2) that will authenticate my phones and tablets devices with AD user accounts and will be on a separate vlan with only access to the Internet.I created 2 policies on the Radius server : one that authenticate computers coming from wireless and a second one authenticating users coming from wireless.
if a user manually creates the WIFI1 network on his phone and enter his AD username, he is going to have access to the corporate network. I would like to be able to say that when a request is coming from WIFI1, only the policy for authenticating wireless devices with computer accounts will apply and the second policy authenticating user wouldn't apply.
I'd like to replace my 4402 Wireless controller with a new 5508. I have migrated the exact configuration from my 4404 controller to the 5508 and they are both running the same version of code. I'm worried that if I replace the 4402 with the 5508 controller, the Access Points will not rejoin to the new controller or they will join but will have lost their configuration e.g. AP Name/location etc etc. AP models registered to the existing controller are 1131, 1142 and 3502. I am also using Cisco WCS.
As long as the new controller has the exact same configuration, is it possible to replace the 4404 with the 5508? Will the existing Access Points join the new controller? Is there any other configuration required? I have read about doing this using mobility groups however would rather not if possible.
I came across this issue with a number of APs in an installtion last week.All APs were new LAP1142s and the controller is 5508.None of the APs (14 in all ) were able to join the controller.Actually they started the joining process , but it seems to get disconnected in between.I am pasting the output below.
Interestingly the issue was resloved after i Resetted All the LAPs again. (all 14 of them worked fine after the reset , but there were no prior configurations on the LAPs , they were just opened From The Box).

What is this .."*Apr 13 07:48:10.043: %MESH-6-CAPWAP_RESTART: Mesh Capwap re-started" that i see on the LAP logs.IWhy is this issue getting resolved on a reset , considering that all 14 of them are brand new , and unboxed at that very moment.
I am trying to configure new 5508wireless controller, AP 1042N model access points are able to receive DHCP IP address from Controller, but not able to join them.
I recently bought a Cisco 5508 WLC with SWC5500LPE-K9-70 and a Cisco 1262 AP with AIR-OPT60-DHCP vender class identifier .How can I check wether the SWC5500LPE-K9-70 is included on the 5508 wlc and AIR-OPT60-DHCP on the 1262 ap?
