Yes you can move it.Just

Yes you can move it.

Just configure the primary WLC ip(On which you want to move this AP) and name in High availbility section.

Hi,First you can enable AP

Hi,

First you can enable AP authorization list on the WLC:

Security > AP Policy then enabel the box Authorize MIC APs against auth-list or AAA.

And then add the mac address of each AP yu want to join. If any AP mac is not present in this list then AP will not join.

 

Hope it helps.

Thanx Sandeep for your reply

Thanx Sandeep for your reply right now this chk box is eabled

Accept Manufactured Installed Certificate (MIC)

now how AP will now that which controller it will connect as i said there are four wism in my network

Hi,The Layer 3 LWAPP WLC

Hi,

The Layer 3 LWAPP WLC discovery algorithm is used to build a controller list. After a controller list is built, the AP selects a WLC and attempts to join the WLC.

1.AP first look for primary and secondary configured WLC.

2.If primary and secondary in not aviolable then it will serach for master controller...
3.If master is also not avilabale then it looks for least loaded WLC. 

 

 

If your AP is connected to diiferent WLC and you want to move that AP to different WLC then you must use AP failover functionality.

you must configure this:

Wireless > Access Points > All APs > Select AP > High Availability Configuration

Here assign the primary WLC IP(to which WLC you want to join).

Thanks again for brief reply

Thanks again for brief reply I am successfully able to add AP to desired WLC infract I used your procedure to add but instead of using your option I used Accept Manufactured Installed Certificate (MIC) option,

Now is there any way to delete the old AP which was faulty ?

Hi,This is mandatory to

Hi,

This is mandatory to accept : Accept Manufactured Installed Certificate (MIC) option,

But I am telling you to enable the box for Authorize MIC APs against auth-list or AAA.

Then add mac address for AP for you want top join to WLC. If AP mac address is not present in WLC then that AP will not join to this WLC.

without enabling your

without enabling your suggested option still i can see the ap staus is up and running its  showing  Admin Status enabled, operational status REG, up time,controller association time etc.

VIP Purple

I know any AP will connect to

I know any AP will connect to this WLC because there is no AP auth list is there.

What I told you is to enable suggested option and add mac address of AP(only that AP  you want join to wlc).

Dont add the mac of this Fault AP to wlc then WLC will not detect and join this AP.

i am confused now why the AP

i am confused now why the AP will connect to this controller there are three other controllers as well ??

VIP Purple

If you have enable the Mac

If you have enable the Mac filtering for AP auth and you did not enter the Mac of fault AP then it will not join to This WLC but it can join to other WLC in network .

why do i need to add faulty

why do i need to add faulty AP again ??? i guess we are heading to wrong direction

VIP Purple

ohhh No.My suggestion is to

ohhh No.

My suggestion is to having AP auth list enabled with mac address of Access Point.

If any AP which dont have the mac address in this list will not join to this WLC.

Like AP 1 have the mac address in auth list then he will join to WLC1.

and AP2 dont have mac address in auth list the it will not join to WLC1.

i rememebr i had done

i rememebr i had done something WLAN network was down for two days , i would be happy to leave the network as it is coz i am the only one who is managing, i strongly believe that if things are working fine dont try to be inoovative

If its the case then its ok.I

If its the case then its ok.

I was just suggesting to have more security while joing to AP.

you are rite sandeep i have

you are rite sandeep i have aroud three hundread APs and 4 controllers its not easy for me to get the All APs , still i did not get the answer how that AP connected to my desired WLC since there are three more WLCs are in the network

VIP Purple

hmmm :)Ok here is the process

hmmm :)

Ok here is the process:

The AP sends CAPWAP discovery messages to discover the controllers, and each controller responds with a CAPWAP discovery response message. After a list of potential controllers is built, the AP chooses to join one of the discovered controllers using the following order of preference:
1. Primary controller: The AP will associate first with its primary controller, assuming the AP has been primed.
2. Upon failing with the primary, the AP will try to register with its secondary and then its tertiary (if configured).
3. If no controller information is primed in the AP, or if the primary, secondary, and tertiary controllers cannot be reached,
the AP then looks for a master controller. The master controller is a feature you configure on a controller (from Controller > Advanced > Master Controller Mode ). Its purpose is precisely to offer a collection point for APs that cannot join their
primary, secondary, or tertiary controller.
4. Finally, if the AP cannot discover a primed controller or a master controller, the AP will select the least loaded from all controllers that have responded to the discovery. Least loaded is relative to the controller license. In that sense, a 2106
controller with 4 APs is more loaded than a WiSM with 30 APs.
5. If no controller can be discovered, the AP reboots and restarts the discovery process.

 

Hope thsi clarify.

Thnaks for your brief reply.1

Thnaks for your brief reply.

1 there is no Master Controller Mode is enabled.

2- there is no pimary, secondary or tertiary is confgired. (not sure)

each controller has 65,66,67,65 APs connected repectively.

lets say if  AP XX is connected to controller A can i forcefully move it to  controller B or C??

 

VIP Purple

Yes you can.By changing the

Yes you can.

By changing the primary and secondary controller config on specific AP.

Wireless > Access Points > All APs > Select AP > High Availability Configuration and put the ip and wlc name as primaty wlc to which you want to join AP.

i have checked my 4

i have checked my 4 controllers and all APs have same config means some of them have primary A and secondary C controller and some of them have primary D and secondary E.

what i understand is whenever i will connect any new AP it will be connected to controller A and once its assciotaed than i can move it to another controller

am i right?

VIP Purple

Just my 2¢When you remove an

Just my 2¢

When you remove an access point or if the AP is no longer joined to a WLC, it will not have an entry in the access point list.  If you manually added a mac filter, then you manually have to remove it.

As far as AP join, etc.  If your brining AP's up, its best to either have master controller enabled or use one of the ap join methods that Sandeep has posted.  Make AP's join only one WLC so you can decide how you will assign AP's to what WLC.  This way, all new AP's will just join one.  If you don't have any of these methods, then its up to the AP which WLC it wants to join.

When the AP has joined, then you should assign the AP to a WL:C.... this should be done on the AP under High Availbility, which Sandeep has posted.  Now you can assing which WLC is the primary, secondary, etc.

This is how it should be done, you should have sites connected on the same WLC and not have them mixed.... not best practice.  That is what is called a salt n pepper design and causes more inter conroller roaming which is not needed.

Example:

WLC1

Site A, B, C

WLC2

Site D,E

WLC3

Site F,G,H

WLC4

Site I,J,K,L

What you want to try to do is balance the number of AP's from a given site to a WLC if you can.  or you can just place sites that are in a region to a WLC.

Thnks Scott for more

Thnks Scott for more information just a quick question if i enable Master Controller Mode on WLC A will it be any service impact on the network i dont want any down time

VIP Purple

No there will be no impact.

No there will be no impact.

Hall of Fame Super Silver

No it will not be, but I only

No it will not be, but I only enable master or any of the other options when I need to join an AP to a WLC.  Master helps you, because you now only have to look at one WLC to find any new access points.  As long as the master WLC is responding to the AP, that AP will join the master. 

You do still need a mechanism for the AP's to find the WLC, but you probably already have that in place.  Again, this would only point to the master.
