WLC HA Redundancy port

Can I setup a 5508 pair of controllers as an HA pair if they're geographically located in different data centers?  From the reading I'm doing, it looks like the redundant port needs to be physically plugged in between the two or am I miss reading?
Thanks,
Pete

Hi Peter,
Yes you can have 2 WLCs on different location as long as you can connect them physically by a cable to redundant port.
Normally its called 1:1 design where one WLC will be in an Active state and the second WLC will be in a Hot Standby state continuously monitoring the health of the Active WLC via a Redundant Port. 
Port which should be connected back to back in order to synchronize the configuration from the Active to the Standby WLC.

  • Redundant port on 5508 WLC

    What is the purpose of Redundant Port that says "future use RJ45" on the Cisco WLC 5508?

    Hi,
    none.
    The new WLC models are actually a common architecture with other products. (you might have noticed the similary between 2106 and the small asa)
    This typically means that there was an extra rj45 ports that is maybe used by the other products having the same hardware but not on the 5508.
    I.e. there is no current use or planned future use for it.

  • Redundancy management IP and Redundancy port IP unreachable issue

    Hi, all
    I got one interesting issue with wireless 5508 controller. we have ordered two WLCs, one is air5508-12-k9, Anther one is air5508-HA-k9.
    Now, we are going to form HA mode and HA box will become standby mode. One issue we are seeing now. after configuring redundancy management IP and Redundancy port IP to both WLCs. primary WLC are working well that we can ping it's all of IPs successfully, however standby WLC are not working well. even it can't ping itself. management IP has no problem.
    Problem is only for redundancy management IP and redundancy Port IP. One interesting thing is our switch can't learn redundancy port's MAC address even it's connecting and interface shows UP. Primary has no this issue.
    Has anyone have the same issue before or appreciate any suggestions and inputs.

    thank you very much that makes sense, so I will need to change service port address ( maybe a class A or C ) or disconnect that port from the network ...
    thank you again very much your help is really appreciated

  • WLC 4402 redundant Link

    We have a WLC, currently it has a single trunk link into a 6506 and all works fine.
    we have recently upgraded network to VSS system , so now we have two 6506 ,   i want to connect the redundant port of 4402 onto the other new switch , is there anything special i need to do?
    as it is a virtual switch it is connecting to, does anyone know if WLC is capable of doing etherchannel or something similar?
    Many thanks

    The question is not on WLC. WLC will bundle its 2 ports the same way whatever happens.
    The question is on the switch. You cannot create an etherchannel that spans several switches, so that won't work. But for the VSS, I think you can create a portchannel that will englobe ports on the 2 switches, so if yes then it's ok with WLC.

  • WLC 2106 redundancy uplinks / LAG

    Hi to all,
    We've a WLC2106 connected to a Distribution switch composed by a stack and 6x APs dislocated on the Access switches.
    All the APs are in H-REAP mode so the WLANs are mapped to the WLC's management interface instead of a dynamic one.
    How can I add redundancy on the connection from the WLC to the Distribution switch since the WLC2106 doesn't support LAG/Channel (implemented on all the WLC4400/5500 installed until yet) nor AP-Manager secondary interfaces???
    Many thanks
    Saluti
    Omar

    Hi Leolaohoo,
    thnx but I want to been able to have a redundacy on network connections from the WLC to the Distribution switches and not having a WLC's redundancy...
    based on your answer I suppose that no network connections redundancy are available on the 2100 models (channel, AP manager secondary interface,...) are available...

  • WLC 2504 redundancy set up

    WLC: 2504
    Firmware: 7.6.100
    Hello,
    I'm getting very confused in how to set up redundancy with WLC 2504. Some sources talk about Client SSO, some about N+1.
    But it seems that although I should use Client SSO with firmware 7.6, the WLC 2504 doesn't support it.
    When I type config redundancy, I have no choice
    >config redundancy ?
    unit           Configure redundancy unit [primary | secondary]
    So I typed "config redundancy unit primary" on my 2504 and "config redundancy unit secondary" on my 2504-HA
    And when I issue this command I have very little information
    >show redundancy summary
    Type of the Unit = Primary
    Does someone has guidelines for redundancy with WLC 2504 on firmware 7.6 ?
    Thank you

    Hello,
    Thank you both for your answers.
    Something I didn't understand in the documentation is this.
    Is there a replication of configuration between the WLC primary and the HA ? I did read that they should have different network settings (IP addresses) so I understand that there is not a total replication, what about the rest of the configuration ?
    The only result I have when I issue a command on the WLC-HA is this
    >show redundancy summary
    Type of the Unit = Secondary
    It doesn't look exactly what I see in the documentation.
    Thank you

  • WLC 5508 Distribution Ports

    Dear Community,
    i have a small Q that should we configure any of distribution port of WLC 5508 with speed 10/100 to connect it with cisco's 3750 on fastethernet port.
    By default WLC ports are gig ports so is there any comand or option to configure the port by decreasing its speedin wlc.
                                                                           OR
    could we connect them in the same status like wlc gig port wit switch 3750 fastethernet port and there will not any speed mismatch and it will work fine.Honestly on my behalf it will not work like this.
    please advise what is the best practice to do that.

    i have a small Q that should we configure any of distribution port of WLC 5508 with speed 10/100 to connect it with cisco's 3750 on fastethernet port.Won't work because the 5508 will negotiate to 1Gb only.

  • WLC geographical redundancy

    Hello,
    There are two "central" locations each one having one satellite or spoke site. Let's have:
    - zone A and its spoke_zone A1
    - zone E and its spoke_zone E1.
    Both region A and region E have a similar deployment scenarios:
    - 1 x 5508 WLC
    - several LWAPs in the existing network (local network).
    - FlexConnect for other several LWAPs for the spoke zones A for the A1 and E for the E1.
    I'm thinking how can I achieve a backup solution for all these 4 sites:
    - A1 and E1 can achieve it through FlexConnect and one mode only: local switching & local authentication.
    - what about A and E regions? How can I bring some backup WLC solution here? I know of Mobility Groups, still I don't think it helps too much as I have only L3 connectivity between A and E region through MPLS.
    What if I try and get L2 connectivity in between using some solutions like "poor-man's EoMPLS" like L2TP v3, I will be able to connect one VLAN pair, will this be enough ?
    - what else can I do in case of WLC breakdown in either of the two regions (A or E)?
    Thanks in advance!

    During these days, here are some advices I received:
    Traditionally, utilizing Backup Controllers was the main way to provide redundancy for a WLC failure. For Zone A, you could just select the Wireless LAN Controller at Zone E, and assign that as the Secondary Controller for each AP as desired. You can set the Primary and Secondary controllers for the AP on the controller via the GUI, the CLI. With Backup Controllers, in the case of a WLC failure AP's would begin to search for their Secondary Controller and re-establish their CAPWAP tunnel. The obvious downside to this, is the outage that occurs from the client prospective while the AP drops it's tunnel and begins to build it again to the Secondary Controller.In response to the need for a somewhat better failover scenario, Cisco brought out High Availability in WLC firmware 7.3. In this scenario, you purchase a second WLC and license it specifically to serve as a standby. You place it adjacent to your existing WLC, and it shares an IP address and session/Config/AP information with the main controller. Now in the event of a WLC failure, the failover from the AP perspective is intended to be transparent.
    Now, 'cause of budgeting I can't think of HA solution so I would go for the Backup Controllers, especially now when there are two primary zones only.
    Except that I myself though at another solution:
    - what if both zone A and E have all LWAPs configured using FlexConnect mode with local switching and authentication? I mean all LWAPs both the APs next to the WLC and also the LWAPs on A1 or E1 zones.
    This will result in having only FlexConnect mode APs and of course some features less available, still for the redundancy point of view what do you think of this?
    You think would be better or worse than "Backup Controllers" solution?
    P.S. the L3 connection between A and E is provided with 150ms or less.

  • Trying to configure dsl line on WLC as separate port not part of the LAG

    I am trying to  configure   port 8  on the WLC 5508  to a  dsl line  that connects to a linksys  switch.  This is seperate from  primary port  which  is  configured as  LAG  and has the rest of the vlans.   I am not sure how best to achieve this.

    The WLC SFP port will negotiate to only 1Gb and nothing less.  You'll need a GLC-TX module to enable to connect an ethernet cable from the Linksys to WLC.

  • Setting up a primary and secondary 5508 using Redundancy Port to share 500 user license in HA

    I will try and keep this short but I am totally lost. Management purchased a HA package from Cisco consisting of 2 5508's with pre installed 500 users license on the Primary WLC and none on the secondary WLC. We have 5508's already so I am familiar with setting them up and so forth. What I am not familiar with is setting them up using HA for failover and license sharing. I've looked and looked and can't find documentation online showing how to set this up. I have found some but nothing that is complete. I have spent 2 days spinning my wheels. Can someone point me to proper way to config these in HA?

  • Cisco WLC 5508 Redundancy Feature

    All,
    With version 7.3 there is a feature for redundancy. How does this feature work? Does anyone know? Can it be use where it is not directly connected, but can be connected as a layer 2?

    There have always been redundancy. v7.3 introduced HA AP SSO... did not really start off pretty well. Even with v7.4, there are still some open issues.
    Here is how redundancy has always been implemented.

  • WLC 5508 redundancy

    Hi All,
    With the 4400 series if the primary controller failed it could take around 30 seconds iirc for the APs to re-associate with the secondary WLC.
    Has this situation improved with the 5508 controller .... can the AP failover in less time?
    Cheers,
    Eoin.

    I don't actually have a specific problem I was just wondering how quick the failover is with the new 5508 controllers versus the 4400 controllers. Can't seem to find documentation around how long it should take for example if I have 250 AP's and 2 5508 controllers.

  • Redundant Port Fowarding?

    On my old airport extreme I could open a port to be forwarded on more then one private ip.
    example:
    Port 5900 Private ip: 10.0.1.2
    Port 5900 Private ip: 10.0.1.4
    Now with the new airport extreme N (Firmware 7.1.1 Software "Airport Utility 5.1") it only allows me to assign one port to one internal ip.
    This causes problems for me having to constantly change port forwarding.
    The older airport extreme a/b/g (forgot which software version, but was different) allowed this.
    Did they break the sofware? Or am I doing something wrong? Is there a work around? Thanks>

    I am aware this only allows one connection at a time, but all I would have to do is shut down one and vice versa, without having to go into port forwarding every time...
    I guess I'll just re-route using different ports...
