• WLC 4404 and high availability

  If I have 2 WLC 4404 are supported 100 Access Points for one and I installed 110 Access Point, I can you decide when a WLC down who are the 10 Access Point which must lie down?

  Thanks for your help

  fcostalunga

  Let me understand your question.

  You have two WLC and can support 100 AP. You have 110 APs. If one of the WLC must go down, how you can configure or say which 10 AP will not be able to join?

  If this is your question, here are some solutions I can think.

  1. H-HARVEST. If you enable REAP H to your AP, when one or ALL of your WLCs must go down, the AP will be able to operate as if the WLC has increased. The exception-to-the-rule is to NOT reload the AP and it should be good.

  2. you can configure, CLI only, 100 AP s primary and secondary controller. 10 AP will no config, so they will go into "limbo".

  I hope this helps.

• WLC 5508 high availability

  Hello

  Today I have two WLC 5508 (with license for 100 AP each of them), on a single site.

  The WLC work availability (active-standby).

  However, we have a new scenario, with 02 sites: A and B (attachment).

  I would like to know if it is possible to work as follows:

  The WLC - A as the main controller of site A. WLC - B as a backup (BDC) of WLC.-a.

  The WLC - B that has the PDC site B. WLC - as a backup (BDC) to WLC - B.

  For example:

  If WLC - a falls, site access Points are managed by B WLC site - B and vice versa.

  Is this possible?

  How can I configure the new scenario? Don't forget, there is a site-to-site between Site A and Site b.

  Another point:

  If I add more than 50 APs on Site A. How does the license number?

  Should I buy a license for the two WLC?

  TKS,

  >....

  >.. .is it possible?

  No. , high availability in terms of controller is supposed to be what is said, the backup controller is not 'full' - stby and cannot play other roles.

• High availability with two 5508 WLAN controllers?

  Hi all

  We are considerung to implement a new wireless solution based on Cisco WLC 5508 and 1262N Access Points. We intend to buy about 30 access points and have two options: either buy a WLC 5508-50 or, for redundancy to, two controllers 5508-25.

  Is it possible to configure two WLC 5508 as a high availability solution, so that all access points are distributed on the two WLCs and during breaks WLC one another case manages all the APs?

  If we have 30 access points, and one of the two WLC 5508-25 breaks of course that not all access to 30 but only 25 points can be managed by one remaining. Is there some sort of control to choose the access points must be managed and which do not?

  How does such a configuration looks like in general, is the implementation of an installation of two controller quite complex or simple?

  Thank you!

  Hi Michael,

  Do not forget that the 5508 works with a system of licensing. The hardware can support up to 500 APs, but it depends on the license that you put in.

  I think 2 5508 with 25 APs license will be more expensive than a 5508 with 50 APs license.

  If you have 2 WLCs, the best is NOT to spread access between the WLCs points. In doing so, you increase the complexity of homelessness (WLCs have to discount customers to each other all the time). If your point was to gain speed, it really doesn't matter as the 5508 can have up to 8 Gbit/s of uplink speed and has the ability of UC to treat 50 APs with no problems at all. So I find it best to have all the access points on 1 WLC, then if something goes wrong, all the APs migrate anyway for the other WLC.

  If you want 50 APs at a 25-degree WLC failover, you can select who will join Yes. The APs have a priority system, so you assign priorities. If the WLC sees it's full capacity but higher priority APs are trying to join, it will kick down-prio APs for the high prio allow to connect.

  WLCs is not exactly "HA." It's just that if you have 2 WLCs work together (as if you had 700 APs and needed to put 2 WLCs) and delivered to customers. Or all APs sat on a WLC and when it breaks down, they join the other available controller.

  The only thing to do is to put each WLC in the same group of mobility so that they know.

• WLC 5508 joined connected vs status

  Hello

  What is the difference between the status of 'Joint' and 'Connected' AP on the controller of Cisco 5508 wireless in HA configuration?

  I have two WLC 5508 in HA configuration. October 3 the controller switchovered with reason "Active controller failed" (attached file 1). I tried to understand why the controller has failed, but I did not find the reason.

  Now, there are a lot of AP (not all) in the 'connected' State, not 'Supported in status' (attached file 2).

  What is the meaning? and why in the details ' AP join stats ' (attachment 3 and 4) tha AP are well attached status? It's a licensing issue? I can solve this problem with a manual failover to main controller?

  Thank you for the help

  You have a license for 250 AP on your primary controller and the secondary is a SKU or has at least 50 AP license to act like a HA.

  As long as the main unit is available for the secondary unit (active) it will not perform the countdown. 90 days don't apply if the main unit is unavailable for more than 90 days in a row. If the secondary image (active) loses power and the principal is unavailable when it starts again, it will go into maintenance mode.

• SHIFT of Mode on Cisco WLC 5508

  Hello

  I have two WLC 5508 working in ACTIVE / standby. They are connected to my local network by linking to each WLC.

  I would like to implement the LAG Mode to have two WLC link but when I activate LAG Mode (Mode CONTROLLER/general/LAG at the next reboot active), I have this newspaper:

  "Error in the setting of the Mode of LAG. Please see the log file.

  I see nothing in the log file.

  The version of my WLC is 8.0.100.0

  Thank you

  First, you will need to disable HA if you want to enable the LAG.

  http://www.Cisco.com/c/en/us/TD/docs/wireless/controller/8-0/Configuration-Guide/b_cg80/b_cg80_chapter_010100001.html

  A time LAG configured on both controllers, you can then enable HA between two WLCs

• WLC controller anchor Cisco HA

  Team - we're going for a refresh of the WLC anchor. Current is 4402 which is used only for the guest user connections, there is no recorded on this AP. We would replace it with 5508 but this time in HA.

  Q. you really go for AIR-CT5508-HA-K9.  Cant we buy only 2 amount of AIR-CT5508-12-K9.  

  Please notify.

  Thank you

  It does not work with zero licenses, but it can work temporary with the evaluation license. So if you order two C1 5508 s you must have at least one license of AP to make it work with HA - SSO in a permanent installation.

• WLC 5508 internal DHCP server issues

  Hello

  I'm hoping to get your comments around the issues of dhcp, I faced with two centrally switched Wireless LAN. I have attempted to explain the installation and the problems below and would be grateful if anyone can suggest a solution for the problems I am facing:

  The configuration is the following:

  -J' have a WLC 5508, which has been configured with 4 SSID, of which 2 are the Central authentication and commissioning.
  -J' have a LWAP connected to the WLC in HREAP mode.
  -WLC is configured as a DHCP server for clients that connect to the SSID "Guest." For the rest, I'm on external dhcp server.
  -Only one scope of comments Interface is configured on the WLC.

  Problems:

  1. as far as I know, to WLC serve internal dhcp server, it is mandatory to have the proxy enabled, but the Clients connecting to 'Internet' SSID are

  Unable to get an external dhcp server ip address, if the proxy dhcp is enabled on the WLC. If I disable the proxy, everything works fine.

  2 DHCP does not release the ip addresses assigned to clients, even after that that they are connected.

  3. If a machine that has previously been connected to "Guest" SSID connects to the 'Internet' SSID, he asks the same ip address, he was charged by the WLC assigned under "Guest", it gets the tag with the Vlan configured on the management interface.

  The controller output *.

• Cisco WLC 5508 &amp; HP printer

  Hello

  I have some problems with cisco and hp airprint wlan systems.

  I use two cisco wlc 5508, a master and an anchor.

  the APs ar connectet to master wlc, DHCP and the point of diversion to the internet are on anchor wlc.

  so far, with my android phone, I can connect and hepatitis has access to the internet.

  now, I use an HP Multifunction (MFP M276nw) printer with Airprint. I connect to the WLAN even the hp printer on the same IP range.

  I can ping the printer from my android tablet, but I can never find the printer with a hp soft.

  If I connect the printer even with the same compressed to a point of user access to home normal is all ok thing.

  I think I have to configure something on my wlcs.

  any ideas?

  Thank you

  It seems that v7.5 supports Hello on anchor. You might want to look at this thread

• Interface WLC 5508 AP-Manager

  Hi, I own a WLC 5508 and (probably), I do not understand the AP Manager interfaces. I have a laboratory with 2 x 1242AG and 1 x 1252AG connected to c2960. APs in vlan 10 (192.168.10.0/24, configured via DHCP), APs are connected to interface 'switchport access mode. C2960 is connected via a trunk to c4506 and WLC is plugged into article gi1/3 and article gi1/4 (both through twingig). The two ports are configured as 'switchport mode trunk ". WLC management interface is IDE oucederomsurlesecondport WLC 8 (linked to article gi1/4), and AP-Manager is on port 1 (connected to article gi1/3) WLC. WLC management interface has 'Management dynamic AP' set to off, and AP-Manager defined activated. The two are interfaces to management and AP-Manager tag, vlan id 12 and 13 (subnets 192.168.12.0/24, 192.168.13.0/24) respectively. APs receive their IP through DHCP configuration (server located in vlan 20, 192.168.20.0, in use ip helper-address) and try to discover DNS resolution WLC (CISCO-CAPWAP - CONTROLLER.some.domain resolves to AP-Manager IP correctly). But AP has the status "not connected" in monitor/statistics/AP join APs do not join to the controller, said WLC "Discovery request Ignoring received on the management interface".

  But if I put management interface as "Dynamic AP activated" and change the DNS to resolve CISCO-CAPWAP... it's IP everything works well - AP is associated with the time. Please help, how to reach the KNEES a AP-Manager interface? Sign up for the Manager of WLC is simple, but my design requires at least 2 interfaces AP Manager.

  If you have a 5508, why you have the AP Manager?

• IPS high-availability Solution

  Hi all

  obligation to have redundancy for appliance IPS placed on data center design, I dug on Cisco docs but found the resilience and the HA (High Availability) from the point of view of IPS could take place in the side of switches (HSRP/Eth channel balance).

  is there a visible way to implement high availability of dynamically!

  Kind regards

  Belal

  Yes Belal, both of the things mentioned by you are right. There is no function available which allows "failover" communications between IPS two boxes as do Cisco firewalls.

  Yes Etherchannel load balance traffic to each pair of IP from sensor single src - dst.

• WLC 5508 management interface

  Hi, I have a design requiring a WLC 5508 be connected to two separate swithces specific wireless. WLC 1 port is connected to the switch A trunk and WLC Port 2 is connected to the switch B. Each switch has its own local VLANS. When I connect the years 1130 towers they need find the interface of management initially then only use management. AP interfaces since there is only a single management interface, if the assignment of management interface on a VLAN that is configured on the switch then APs on spend a fine join but those switch B continue to ask for the management interface and the version debug capwap on WLC he says that this query Join were received on the bad ineterface...

  the only work around that was to do the routing between switch A and switch B for both VLAN residing APs... but for security reasons - customer would like to avoid this

  any help is appreciated...

  Unfortunately, the initial discovery must arrive in the management interface.  Once this has happened the AP expected the second AP manager who is on the subnet of comments, therefore, they are able to stand.  But if the AP is restarted, it would need to discover once again and would fail.

  What is the concern of customers to have all routable network mgmt AP?  guest users can not see anything there.

  IMO, let the AP able to connect to the subnet of mgmt, but then put an ACL L3 upward, to block the subnet of comments to achieve anything in the internal network.

• SNS with high availability option

  I need help to understand the requirements of network and connectivity to deployment Cisco show and share with the high availability option where the DC and DR are different geographical locations.

  Hi, Datar,

  I already asked this question to the TAC, and it is unfortunately clear today the HA mode with 2 servers connected mode "back to back" via Ethernet2, REQUIRES to be on the same network of L2.

  It is not yet based on the IP routing layer, and therefore it is did not in charge of the design when using remote data centers...

  :-(

  It's a shame, I know, and I pointed to the BU of the SnS.

  May be part of a next version of work will be based on network IP L3 routed...

  Wait and see.
