WLC mobility group between 4404 and 5508 controllers

Mobility 'Control and Data Path Down' between 4404 and 5508 WLC's.

 

Hello, we have 5 x 4404 WLC's running 7.0.240.0 with mobility configured fine between them.

We have installed a 5508 with HA running 7.4.110.0, and have tried to add it to the mobility group, however we see 'Control and Data Path Down' between the new 5508 and all the 4404 controllers.

All controllers have:

The same virtual address

Management interfaces are in the same VLAN, and indeed all the controllers connect via the same pair of 3750X stacked switches.

The default mobility domain name is the same

4404 output when issung the command 'show mobility summary'

Symmetric Mobility Tunneling (current) .......... Enabled
Symmetric Mobility Tunneling (after reboot) ..... Enabled
Mobility Protocol Port........................... 16666
Default Mobility Domain.......................... SGH-Mobility
Multicast Mode .................................. Disabled
Mobility Domain ID for 802.11r................... 0xe209
Mobility Keepalive Interval...................... 10
Mobility Keepalive Count......................... 3

5508 ouput when issueing the command 'show mobility summary'

I've spent quite some time double checking all the configurations to no avail.

Has anybody seen this problem before?

Kind regards

HI Bell,

Simple is to Login to each controller and collect the MAC address, IP address from:

Controller > Mobility Management > Mobility Groups, here you will find the right mac and IP address from each controller and then paste these info in each wlc.

Did you add the mac addressi

Did you add the mac addressi/ip address of each wlc to other wlc.

Please check this post: http://rscciew.wordpress.com/2014/07/10/mobility-configuring-on-wlc/ 

 

after adding the details of each wlc to each, please test as per this post:

Thanks Sandeep. I am well

Thanks Sandeep.
 

I am well versed with WLC's and mobility, however trying to add a 5508 to a mobility group with 4404's has come up with a bit of a curve ball.

All the 4404 controllers all joined the mobility group fine, no problems at all - its only the 5508 I am struggling with.

In theory its simple, populate the IP address, and MAC addres of the management interface of the remote WLC, as long as the management interfaces are in the same VLAN, and the Default Mobility Domain Name are the same it should come up.

 

Interestingly I have found the 5508 reports its own management interface MAC address incorrectly when viewing the Mobility Groups:

 

For example:

{Screen shot WLC1.jpg}

5508 management address is 10.95.x.x and when viewing the Mobility Management screen it shows its own MAC address as bc:16:65:f9:37:60.

 

however!

From our router is I do an sh arp | i 10.95.x.x (controller management address), I see:f872.eaee.becf.

{Screen shot wlc2.jpg}

Hence the WLC reports as: bc:16:65:f9:37:60

and

The network reports as: f872.eaee.becf for the same IP address.

I have changed the other WLC's to the MAC adress seen on the network for the new controller, aka changed from

bc:16:65:f9:37:60

to

f8:72:ea:ee:be:cf

I now see the controllers reporting the mobility with the new controller as 'Control Path Down', however I am at a loss as to what may be causing this?

 

Kind regards
