with FW 7.4.100.0 a 2500 controller works as anchor controller, now.I have 3 questions.
1) What are the limitations? 15 EoIP tunnel, Clients? something else?
2) Have Cisco a compatibility matrix about Anchor - Foreign Firmware? (Example works 7.4.100.0 anchor with 7.0.x.x foreign?)
3) A controller works only as anchor. A controller version with lowest AP licence is needed. Right?
I just read that starting from version 7.4, the 2500 controller can be used to terminate guest anchor tunnels. have a question regarding the performance of the internal DHCP server when used in guest environments.
View 1 Replies View RelatedI have some concern regarding the compatibility of AP with the WLC. we are using AIR-CT2504(7.0.116.0) series WLC with AP AIR-LAP1242AG(7.0.116.0) but now i checked on Cisco website they are End-of-Sale/End-of-Life for the Power Supply for Cisco Aironet 1130, 1140, 1240 and 1300 Series Access Point.
Now My question is:
1: Which is the latest AP series we should use for WLC 2500 series?
I have found that there are only few configuration to the Cisco Aironet 600 OEAP. The settings are just for basic configuration for a wireless network when it is in autonomous mode.
A need for a Wireless LAN Controller to perform advance settings.
Also, there are no firmware available in Cisco. No upgrade/downgrade firmware avalaible for download.
Is there any limitations of network size for an interface in a WLC 5508? Any recomendations of netmask size? Maximum /24, maximun /21?
View 5 Replies View RelatedWe 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.
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.
View 4 Replies View RelatedWe have got a WLC 4402 as an anchor that provides guest internet access to our visitors. Our wan sites have 4402's running a tunnel to this anchor for guest traffic. We have got a new site coming up that will have a 5508 as its WLC. I am trying to determine if the 5508 will successfully form a tunnel with the existing 4402 anchor. I am assuming that it will be ok or maybe the 4402 will require an ios upgrade. Our AP's everywhere are 1131's but the new site will have the later versions which can work with the CAPWAP based 5508.
will the tunnel between the 4402 and 5508 work well or will it require an ios + bootstrap upgrade on the 4402 and subsequently the rest of the 4402's or it will not work altogetherwill the CAPWAP AP's at the new site work well with the 4402 LWAPP anchor - I am assuming that they will since the CAPWAP compatibility requirements are really between the AP and its local WLC. Our 4402's are on 4.2.61.0 and I am proposing to management that we should upgrade these to 7.0.116.0 to prepare the infrastructure for any potential issues.
All controllers are in version 7.2.111.3.C1 is a 5508, it is ou anchor controller.C2 is a 5508, it is a big site controller.C3 is a 2504, it is a small site controller. C2 and C3 are in the same mobility group than C1 (and all is up up in mobilty managment). When "DHCP Addr. Assignment" is enable on C1 : Clients on C2 received their IP address by our external DHCP server via C1 and the guest tunneling betwenn C1 and C2 and all is working fine. Clients on C3 don't received their IP address by our external DHCP server via C1 and the guest tunneling betwenn C1 and C3, so nothing work.
View 4 Replies View Relateddeploying a DMZ wireless controller and I have a question regarding remote wired LANs. My 602OEAP APs support 1 or 2 of their LAN ports as being accessible across the DTLS tunnel.This works fine when they register across internet right to my internal WLC. However, now that I'm implementing a DMZ controller for this purpose, how will this work? I dont see the option for the Remote Wired LAN to be linked to a mobility anchor.Some of my users have printers connected to the LAN port on their 602OEAP and I need to maintain this functionality once I move their APs to the DMZ controller.
Software versions: 7.4.100.0
DMZ Controller: 2504
INT Controller: 5508
I'm trying to research the tunnel limits on a 5508 controller if you're terminating controllers to two different SSID's. For example. In my DMZ i have a GUEST SSID for contractors and guests and then I have another SSID used by employees so that tablet and mobile phone users can access the interenet. Because we don't trust any of these devices we have that SSID is termiated just as we do our GUEST SSID.
To reduce the number of anchor controllers I deploy, I wanted to start with one 5508 Controller. (then move up to about 3) This controller would have two SSID's, GUEST & MOBILE. On the Foreign controllers when I setup anchor tunneling I will be anchoring to the same controller however to two different SSID's.
Per the 5508 specs it supports 71 tunnels.
So my question to the group is, will the 5508 see this anchoring as one tunnel each? Or does it support 71 Tunnels per SSID?
We have Internal Wireless Controllers to be set up for HA (AP SSO) and wireless traffic from Guest SSID will be terminated on a Guest Anchor Controller inside Firewall DMZ. The Internal WLC controllers are installed with software versions 7.3.101.0, and the Guest Anchor controller is installed with software version 7.2.103.0. Just wondering if the Guest Anchor controller needs an upgrade to match the software versions on the HA controllers. Also, Cisco provides a new version of code, 7.3.112.0 now. So is it recommended to install the new software version on the HA controllers as well as the Guest Anchor Controller.
View 8 Replies View RelatedI know that the recommendation from Cisco for the mobility anchor feature to work well is to use the same IOS version on the anchor WLC and local WLC controller. Now I´ll install on a new site a 5508 local WLC with a newer IOS version which is installed on the other controllers ( Guest and local ). Later I´ve planned to update also the other controllers to the same IOS version. Now my question is, must I upgrade all other controller at the same time ?
View 4 Replies View RelatedI am in process of replacing our 44xx controllers with new 55xx controllers. During the upgrade, I would like to add redundancy to our guest controllers that reside in the DMZ and had a question about regarding the setup.
If I remember correctly, I would place both guest controllers on the same mobilty group, and then add both of the controllers to the foreign controllers. The foreign controllers will form mobility with both anchors, but choose the one with the lowest MAC address as primary. On the foreign controller, if the lowest MAC addressed anchor controller does not respond, it will connect to the second controller. Is that still true? or is there a better way to go about it?
Also, I was wondering, do I need to put different guest network ranges on each of the Anchor controller? or can I use the same exact range on both anchor controller (since if a controller goes down, the clients would be reconnecting to the second controller anyways?)
Any best way to setup redundant Anchor (guest) controllers).
Just installed the E3200 and use to have a WRT54G. Wanted the N Band.Noticed two major deficiencies.
1) this device does not have Internet Access Policy option and the Parental Control interface is unbelievably poor?There are very few options to work with in terms of time of day to turn on and off blocking access. (Half hour increments only, not 5 minutes increments that I was use to). The "FROM" Field has AM only and the "TO" filed has PM only. This means if you wish a device to have access pass Midnight, you can't, or if you wish to block beginning in the AM, you can't. Furthermore there are no day selections, just School Night and Weekend Night. What if you just want to block school Night. You can't "turn off" weekend. Is there a way to gett full Internet Access firmware into this device.
2) When using Parental Control the devices to restrict access are only displayed by default names. I have 8 devices on the LAN and half of them say Network Device. Any way to identify them by a device name or MAC ID?
I have a Fiber to Ethernet connector from my ISP. The Ethernet cable goes to an iSP issued Zyxel router. Into this router the landline phoneservice connects to give us VoIP landline service (which is cheaper). An Ethernet cable goes from the Internet port on the E4200 to a LAN port on the Zyxel router. That works great but I had to put the E4200 into Bridge Mode to get it to connect to the Internet via the Zyxel router which I need to use the phone services my ISP provides. I bought the E4200 because I wanted to use the dualband functionally and get a 802.11N 5GHz network setup and to give me the ability to block certian websites and services which I knew Cisco/Linksys is famous for - the abillity to control your network.
Well then imagine my surprise when I could not use the Parental Control settings when the router is in Bridge Mode... This was the reason I bought this router over an Apple Airport Exreme. Is there anyway to get it to let me use the Parental Control anyway while in Bridge Mode or a better way for me to connect the router with the rest of my network?
We currently have all of our foreign AP controllers on software version 7.0.116. This consists of a mixture of 4400 and 5508 WLC's. Our guest anchor is a 4402 on version 7.0.116. We are replacing the guest anchor with a 5508. We are also upgrading our 5508 wireless controllers to version 7.2 to support the 3600 series AP's. My question is what is the recommeded code that the anchor controller should be on? Should it also be upgraded to 7.2? If we upgrade the anchor controller to version 7.2, will this affect anchoring to 4400 series foreign controllers still on7.0.116?
View 9 Replies View RelatedI'm attempting to set up (for testing purposes) a 2nd 'guest' SSID on an internal WLC (WLC-A), and terminate it in a DMZ on an anchor controller (WLC-B). We already have a guest SSID originating on WLC-A and terminating on WLC-B though. Is it possible to originate a 2nd guest SSID on WLC-A?
WLC-A - 2504 (7.2.x)
WLC-B - 5508 (7.2.x)
The problem I'm seeing is I'm getting no DHCP address assigned on the test SSID. If I statically assign IP information I still have no connectivity. It's as if the EoIP tunnel for the 2nd test SSID isn't functional.
We are planning a WLAN upgrade and the security policy is to forward wireless Guest user traffic to the DMZ controllers. We are now considering the Virtual WLAN Controller and all AP's will register with the virtual controllers and we will use Flexconnect for Staff and internal traffic that will switch their traffic onto the local switch.
We wish to forward the guest traffic to the DMZ Guest Anchor controller which will be a 5508 controller. This will also offer Office Extend AP service.I have looked at teh virtual controller docs and not very clear if this deployment model is supported. Below is a diagram of what we wish to deploy and is this a supported deployment model.
I have implemented a Guest WLAN solution as per the recommended design from Cisco. We have two internal WiSM2 controllers providing services for Internal secure SSIDs. Both these controllers are members of a Mobility and RF management group.
Two 5508 controllers have been installed in our DMZ for resilience and have been placed into a separate Mobility group. All controllers (internal and external) have been linked together as mobility neighbours in a full mesh and a new SSID for Web Guest traffic has been anchored to the controllers in the DMZ.
Web page authentication works perfectly fine, but I cannot for the life of me get the MAC filtering override to work, i.e. if a MAC address is present, do not redirect to the splash page for web auth.
We have a Cisco 4400 series wireless controller deployed as a Guest Anchor in a private DMZ. We have 13 foreign controllers anchored to this for Guest Wireless. We recently anchored 17 additional controllers to this Anchor controller. Since we have done that, periodically on just 3 of the foreign controllers, the control path shows down on the mobility peer, then comes back up. We have had this issue in the past, but it resolved itself. However, now we are seeing this issue again. Are we reaching a limit on EoIP tunnels? I have read that there is a max of 71, and that is per controller, not SSID. We do have a firewall in the middle but all necessary ports are open.
We have had this issue for quite sometime, it just does not happen frequently. Since we have added the additional controllers, it is now happpening very often, but only with 3 controllers. There is not much in common with these 3 controllers. 2 are 4400 series, and 1 is a 5508. All 3 are local on a campus LAN, different networks. Could it have anything to do with memory or utilization?
In our test set up, we have two WLC 5508 Controllers connected via Checkpoint UTM-1 firewall Inside and DMZ Interfaces. Both the WLC controllers are connected to the firewall via Cisco 3750 switch. On the Local (Inside) Controller, guest SSID is enabled and attached to the wireless management Interface. On the remote anchor controller, guest SSID is enabled and attached to the Management Interface as well. The following configs are replicated on both the Controllers.
SSID Name - guest
Interface - Management ( VLAN 10 on Local and VLAN 20 on remote) -
Mobility Group: Same configs at both ends
SSID Anchor : Anchor SSID on local and local SSID on Anchor.
AP: CAPWAP 3502 Management Subnet
[code]....
Is there any thing missing in the wireless configs and or the firewall rules as i could not see DHCP request back from the Anchor Controller. Also, after DHCP is obtained, the web authentication request will be redirected to an Amigopod device for authentication. In this case is the redirect URL congiguration to be performed only on the Anchor Controller or is this to be replicated on both the Local and Anchor Controllers.
We have been deploying 3502 APs remotely to locations with full T1s that backhaul to where I sit at HQ. Both the foreign and anchor controller are here at my location.
I am seeking to rate limit per user the bandwidth each client will get on the guest internet ssid. As you know this traffic is encapsulated in capwap between the AP and the controller so I cant use a standard ACL on the switch or router.
We are trying to keep the guest internet access usage in check on the T1 at any given site so the other ssid's & local lan traffic is not overly competing for the bandwidth.
I found the place to edit the default profiles in the controller but the documentation really isnt clear on best practices.
So I put it to you my fellow wireless engineers to suggest how you are implementing bandwidth management on your wireless guest internet.
Oh and here is my hardware & software levels.

We have the following architecture for Internet access:
LAN ---- CISCO-CHASSIS----FIREWALL-----INTERNET
My concern is about PAT, for LAN users Internet access: I would like that PAT is performed by Cisco chassis(in my case, a C4500), not by firewall (which means: local IP addresses for flows from LAN to Internet are all natted with the same public IP address).Are there some drawbacks to this design? I guess there is no problem for classical flows, but what about flows with specific comportment (such as FTP) on Cisco routers?
I'm currently running 8.3(2) on my 5520s in an active/standby config. The 5520s have the 2GB RAM upgrade and 256MB flash card. Are there any CPU limitations in going to 8.4?

I'm configuring a 2500 series WLC to test some wireless configuration changes we'd like to make on our 5500's that are currently in prodcution.
The 2500 and the 5800's interfaces are configured as a LAG.
One of the primary goals of these configuration changes is to move the LAPs from their current VLAN (the same subnet as our primary WLAN) to two separate VLANs. Were choosing to move the LAPs to 2 APs based on the WLC best practices document's suggestion to limit the number of LAPs per vlan to 60-100. We've had several issues in the past with LAPs failing to join with their static IPs, releasing them and then joining with DHCP addresses.
LAP's will be on separate vlans using subnets 10.10.10.0/25 and 10.10.10.128/25. WLC management interface is in the 10.10.1.0/25 subnet.
Should we continue using static IPs for the LAPs or DHCP?
What subnet should the AP management interface be on?
Is it possible to have mutiple AP management interfaces with LAG?
