Mobility group same ssid multiple WLC

I have a 4400 and a 5508 WLC in the same location
We want to be able to roam between ap joined to both the 4400 and the 5508 using only one ssid
Do I only need to create a mobility group and add both WLC
then create only one WLAN on one of the controllers and it will be shared across bot WLC.
Or something else?

Resolution :
Yes you are correct. Please follow this link for Mobility groups and Roaming :

Can we create Mobility group between WISM2 and WLC 5500

Dears,
I need your feedback urgent please,
Can we create Mobility Group between WISM2 and WLC 5500
Firmware for WISM2 > 7.4.121.0
Firmware for WLC5500 > 6.0.196.0
I created Mobility Group with (IP address , MAC Address and Mobility group name) for Foreign Controller. if any configuration required from my side.
Wait your feedback urgent please
Regards,

Hi,
Controllers do not have to be of the same model to be a member of a mobility group. Mobility groups can be comprised of any combination of controller platforms.
Thats enough :)

Multiple Groups, Same People, Multiple Different Email Addresses Per Group

I have some groups I need to set up, let's call them the GroupsIN, GroupsOUT and GROUPS.
These groups have the same members, two people with two and three email addresses respectively. Let's say their addresses are:
Rhonda Rodeo:
[email protected]
[email protected]
Clarissa Cowgirl:
[email protected]
[email protected]
[email protected]
This is how I'd like to set the groups up:
GroupsIN:
[email protected]
[email protected]
GroupsOUT:
[email protected]
[email protected]
[email protected]
GROUPS:
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
So, that's three groups with two persons and separate email groupings for each, one of which would contain all the email addresses for those persons.
I've looked in the archives and don't see anything that specifically addresses this and can't see an obvious way to do it in "Edit Distribution List". I could do it by creating new alternate names for each of these persons such as R Rodeo and C Cowgirl as group one, RRodeo and Ccowgirl for group two and Ronda Rodeo and Clarissa Cowgirl for group three, but I use the address book to sync my Palm phone and I don't want all those extra names and addresses in there and it would just get generally confusing that way.
Is there another way?
JoeL

If a Group member has more than one email address and you want to send to all email addresses for the member when addressing a message to the Group, the member with more than one email address needs to be copied within the Group for each email address.
If a Group member has 3 email addresses and you want to send to all email addresses for this member when addressing a message to the Group, this Group member must have 3 entries in the Group which can be done via copy and paste for the member within the Group and then use Edit Distribution list selecting a different email address for each Group member.
This is the only way that I'm aware of.

Mobility Group Requirements for Guest Anchor WLC

Hello -
I've alway assumed you can't create a guest tunnel between a local WLC and an anchor WLC that are in different mobility groups.   However, I was told recently (without much detail) that this is possible. So I have set out to test this.
I am trying to point one of my local WLCs guest SSIDs to a guest anchor WLC in a different mobility group.   I have a maintenance window coming up and I am looking to anchor the clients on one campus to the anchor WLC on the other campus so guest service does not go down.   Each campus is it's own mobility group.   In trying to set this up I went to the "mobility anchors" screen for the guest SSID on one of the local WLCs and I am unable to add the anchor WLC from the other campus because it's non in the drop-down menu. This is because it's not in the same mobility group.   So my question is how do I anchor clients coming through a local WLC in one mobility group to an anchor WLC in another mobility group?
To me it doesn't seem possible without significant configuration changes.   I don't want to reconfigure/recreate mobility groups.
Thanks
Chuck

Not only is it possible, I would recommend it. However, you may be confusing some concepts.
The Mobility Group is different than the Mobility Domain. I generally refer to the Mobility Group as those WLCs with the same Default Mobility Group Name, and the Mobility Domain as the entire Mobility List (where you can define up to 72 controllers from various mobility groups).
The point is that if WLCs 1-10 are GroupA, and WLCs 11-20 are GroupB, for anchoring to work you at least need to add the anchor to the mobility list of the foreign wlc, and vice versa.
If you notice, when you add a mobility entry to the list, it should ask you for mobility group. If you leave it blank, it should default to that of that WLC, but on GroupA controllers, you could define GroupB controllers (and specific GroupB) and then you should now have mobility established between your controllers and the Anchor configuration will have your anchors in the drop-down....
Does that make sense?

Mobility Group Table *MUST* be populated in each WLC in same mobility group

For what it's worth,
I recently discovered that when you have multiple controllers and want to implement Mobility Groups, more is needed than simply entering the same Default Mobility Group Name for each controller within the mobility group. The following is required:
a) The IP address of the "Virtual" interface on each controller must be identical on each controller within the mobility group.
b) The Default Mobility Group Name must be identical on each controller within the mobility group (case sensitive).
c) The mobility table must be populated with an entry for each controller within the mobility group.
Otherwise, you will see some inexplicable behavior such as:
* LWAP access points refusing to change to a different controller, even if their primary controller is explicitly set and the LWAP is rebooted.
* LWAP access points unable to find any other wireless controller other than the one pointed to by the "CISCO-LWAPP-CONTROLLER" DNS entry (presumably, this would also be the case if DHCP Option 43 is used to point the LWAP to a controller). Once the first controller reaches its max. capacity of LWAPs, no more LWAPs can join.
* Even MASTER CONTROLLER MODE has no effect.
Cisco TAC was able to explain the great mystery of the Mobilty Group Table to me. However, unless you know your problem is related to mobility groups issues, you might not know to start there (I know I didn't).
The least difficult method I have found for populating the mobility group table is as follows:
Build a text file with one entry for each controller in the mobility group as follows:
Log into the GUI for each controller and selecting: Controller -> Mobility Management -> Mobility Groups, click the "EDIT ALL" button and copy the MAC and IP address from the text box into a text file using NOTEPAD. Repeat this for each controller, creating a new line for each:
The format for the entries is as follows:
00:1a:6c:91:22:A0 192.168.20.44
00:1a:6c:91:22:B4 192.168.20.45
Once the text file is completed (one entry for each controller in the mobilit group), click the EDITALL button and copy the entire contents of the text file and paste it into the text box on the controller GUI, click the APPLY button and click Save Changes. Repeat for each controller.
Again, make sure that the following settings are IDENTICAL in each of the controllers in the Mobility Group:
* The IP address of the "virtual" interface ( Controller -> interfaces ) must be the same on all controllers.
* The "Default Mobility Domain Name" ( Controller -> General ) must be identical on each controller in the mobility group (note: the Mobility Domain Name is case sensitive).
After making changes directly to the controllers, a "refresh from controller" in the WCS might be needed to get the WCS to attempt to synchronize itself with the controllers.
Here is a link to the 4.2 Wireless Controller Configuration Guide which discusses this in greater detail.
http://www.cisco.com/en/US/products/ps6366/products_configuration_guide_chapter09186a00808e638b.html
It is unfortunate that there are currently no mechanisms in the WCS 4.2 to make these changes in bulk (i.e.: The WCS has no Controller Template to do this).
Also, if you ever need to replace a controller, you will need to update the Mobility Group Table in each controller in the Mobility Group (since the tables will have the MAC address of the old controller which will now be different in the new replacement controller).
Despite having used the "unified" product for some time now, there are still surprises from time to time. I just thought that I would share my experience for those who may want avoid it and/or who may be encountering any of odd the behavior described above.

WLC 4400 - Different minor versions same mobility group?

Hi all,
i have 2 WLC 4400 integraded in 3750G.
One has 6.0.202 and the other 6.0.188.
They are in different places but now i want to put them in the same mobility group.
Will this difference be a problem?
BR
Anthony

Yes it will be an issue. You have to remember that the AP gets it firmware from the WLC image. So if an AP has to mi e from one to the other, it will either upgrade or downgrade each time. Best practice is to keep the firmware the same.

WLC 5508 * 2 & Mobility Group

What I am trying to configure is Mobility Groups.
My understanding is that this will allow AP to successfully register and fail over over seamlessly if any of the WLC had to fail ?
It could be I am confusing two things into one :( & I am totally confused and not understanding the benefits of mobility group mentioned above.
Also when a AP starts up and registers with the WLC ......I click on a registered AP > High Availability ( Primary / Sec / Tertiary ) all fields are blank...
Initially I also thought that once my SSO is all setup and working than those options "AP > High Availability" will get populated automatically but clearly not unless something is not working.
My current config is as follows:-
WLC 5508 * 2
WLC 1 - Primary
WLC 2 - HA SKU (Secondary )
Redundancy = SSO (Both AP and Client SSO)

TA,
Mobility and mobility groups are used for the wireless users roaming. What we know that a wireless users can roam between different APs within the same WLC, but when the SSID is used within multiple WLCs, and the client wanted to roam to an AP joined to another WLC, you would need to configure WLC mobility to maintain seamless roaming. For more info:
http://www.cisco.com/c/en/us/td/docs/wireless/controller/8-0/configuration-guide/b_cg80/b_cg80_chapter_010001101.html
Now, I understand that your purpose is to have high availability for your APs. No this is done traditionally from the AP page, under HA tab, where you configure the WLCs names and IPs there. This can be done manually on each AP (you can use CLI to make it easier) or you can push a configuration template using a management server (WCS/NCS/CPI).
Configuring HA on the AP:
http://www.cisco.com/c/en/us/td/docs/wireless/controller/8-0/configuration-guide/b_cg80/b_cg80_chapter_01110000.html
http://www.cisco.com/c/en/us/td/docs/wireless/controller/8-0/configuration-guide/b_cg80/b_cg80_chapter_01110001.html
Using CPI to push AP configuration templates:
http://www.cisco.com/c/en/us/td/docs/wireless/prime_infrastructure/2-0/configuration/guide/pi_20_cg/temp.html
Now mobility may play a role in this, as if you have already configured mobility for your WLCs, then you won't need to configure a "name" for the WLCs when you add them under the HA tab in AP configuration page. That's it.

WLC 5508 and mobility groups

Hi,
We are using 2 WLC 5508 running 7.0.98.0 sw (AP's are 1142) at our primary site. They are hosting 3 different WLAN/SSID's, one for guest and the
other 2 are for corporate access. We have put the WLC's in a mobility group, say "AAAA".
Now we have the need for our UK peer site to publish a corp WLAN that exists in UK - at our site, and when trying to configure for that (following the c70cg.pdf) - I put the WLC's for UK in a new mobility group, say "BBBB". But i can't add our WLC's into that mobilty group
(i get a duplicate mac address message).
What's the correct way of configuring this, does all WLCs need to be in the same mobility group?
Is there some reason why we can't have 2 mobility groups? Is there any upside/downside to configuring 2 mob. groups?
Any clearification would be greatly appreciated
BR
//Mikael

I think you are misunderstanding , so far what you did on your local swedish site is correct. Your two swedish WLCs have to be in their own same mobility group so you can give seamless roaming to your wireless users across your swedish area without interruption.
On a WLC mobility group config page, you can have only one entry per WLC, this is why you are getting the duplicate error message.
WEBGUI - CONTROLLER - MOBILITY MANAGEMENT - MOBILITY GROUPS
If you want to put your 4 WLCs so they exchange mobility messages, the following has to happen on all 4 WLCs.
xx:xx:xx:xx:xx:xx 192.168.1.1 uk
yy:yy:yy:yy:yy:yy 192.168.1.2 uk
zz:zz:zz:zz:zz:zz 172.17.1.1 sweden
aa:aa:aa:aa:aa:aa 172.17.1.2 sweden
Note when you add WLC on the mobility section, the WLC start sending messages to each like, hey i have this client and you have that client and so on. But this has nothing to do with what you are trying to achieve.
With regards to the execs that are coming, yes, replicate the SSID and point it to the Radius Server they have in UK, add your swedish WLC(s) as a NAS on the Radius Server and it should work as if they were in UK. that should be enough and i advise you to do the following for mobility groups config.
on the two UK WLCs
xx:xx:xx:xx:xx:xx 192.168.1.1 uk
yy:yy:yy:yy:yy:yy 192.168.1.2 uk
on the two Swedish WLCs
zz:zz:zz:zz:zz:zz 172.17.1.1 sweden
aa:aa:aa:aa:aa:aa 172.17.1.2 sweden
hope i cleared it out for you. greeting from cold Belgium tonight :-) and hope the execs will enjoy Sweden!

Replace WLC Mobility Group Anchor

We have 2 5508 and 1 4402 WLCs and all belong to the same mobility group. The 4402 does not have any access points and does nothing more than serve as a mobility anchor for our public wireless SSID. We are planning to replace the 4402 with a new 2504 unit which will have the same configuration including IP as the 4402. Is there anything I need to do with the mobility groups when we remove the 4402?
Thanks for any help.
Jeff

you'll need to add the MAC of the 2504 to the mobility group, and remove the entry for the 4402.
Out of Curiosity...how many concurrent guest users to you have usually?

Howto block p2p traffic of clients connected to the same ssid on different wlc

Hi all,
I use two wlc 4400 (4.2.x version) with a mobility domain and one ssid, both wlc are connected to a cisco l2 switch infrastructure. On the wlc I use the p2p blocking action 'drop' (http://www.cisco.com/en/US/docs/wireless/controller/5.2/configuration/guide/c52wlan.html#wp1209597) to isolate the clients from each other. Does anybody know if only unicast traffic is blocked or also multicast and broadcast traffic like arp requests?
Concerning blocking p2p traffic of clients connected to the same ssid but different controllers I found the following statement in the LAP FAQs (http://www.cisco.com/en/US/products/hw/wireless/ps430/products_qanda_item09186a00806a4da3.shtml):
===
Q. In autonomous APs, Public Secure Packet Forwarding (PSPF) is used to avoid client devices associated to this AP from inadvertently sharing files with other client devices on the wireless network. Is there any equivalent feature in Lightweight APs?
A. The feature or the mode that performs the similar function of PSPF in lightweight architecture is called peer-to-peer blocking mode. Peer-to-peer blocking mode is actually available with the controllers that manage the LAP. If this mode is disabled on the controller (which is the default setting), it allows the wireless clients to communicate with each other through the controller. If the mode is enabled, it blocks the communication between clients through the controller. It only works among the APs that have joined to the same controller. When enabled, this mode does not block wireless clients terminated on one controller from the ability to get to wireless clients terminated on a different controller, even in the same mobility group.
===
Does anybody know what's the best practise to prevent this inter wlc client traffic? I already read about using acls on the wlc dynamic interfaces, or private vlans on the l2 switch vlans where the dynamic interfaces are connected to. Is it allowed to completely isolate the wlc from each other on these dynamic interfaces with acls or private vlans or do the wlc need to see each other on this interfaces (e.g. heart beat)?
Many thanks in advance,
Thorsten

Hi Sasha,Thorsten
The bug is Junked and I believe which is what you are running into with your tests:
CSCtr60787 WLC P2P Blocking Set to Forward-UpStream Doesn't Work.
Bugtoolkit : http://tools.cisco.com/Support/BugToolKit/action.do?hdnAction=searchBugs
To answer your original query :
ACL is only solution to block client communication on same ssid between 2 wlcs. 5508 works better with ACLs then 44xx platform.
ARP requests will be forwarded to upstream router just like any other traffic. WLC won't proxy arp for clients on same vlan.
Gateway arp's I believe should be handled by WLC . ( Don't quote me on this but I am pretty sure it is ) ..If it was not, then how would client know about gw ?
Multicast traffic is not applicable for p2p.
Your ACL can be as simple as this for the scenario :
WLC 1 - clientvlan = 10
WLC 2 - clientvlan = 10
and you want to restrict users from wlc1-wlc1, wlc1-wlc2, wlc2-wlc2 for same vlan10.
Basically in that case the ACL should look like on both WLCs :
1. Permit statement to talk to gateway.
2. Deny to subnet.
3. Permit all.
4. If DHCP/DNS other services are on same subnet then you would need to add a permit
statement before the deny.
5. Attach the ACL to SSID or dymanic interface.
Thanks..Salil

WLC 5500 mobility group failover

Hey
I have a Question i am testing mobility group with
Failover for redundend connection between 2
Cisco 5500 Wlc.
On both the controllers i got the mobility working
And both the controllers have the same version
And configuration.
But when i unplug the main controller the access-
Points don't convers to the second one
The just keep on creaming can't find the main controller
Also with this thus the second wlc need to have the same
Interface ip address like managment..??
Thanks

What do you mean by "convers". An AP will only join one wlc and when that primary wlc is no longer available, should failover to the other/secondary wlc. Mobility is required for an AP to know about all the other APs in that mobility group. And if not configured correct, your AP will only be able to join that wlc.
Thanks,

WLC Mobility Group Confusion

Can some please clarify how Mobility groups work and when to use them. I have 2 data centers, each with a WLC, for centralized control. I just want to provide simple redundancy.
When should I use an Anchor group.
Thanks for your help.

To make it simple, any wlc's that will be a primary, secondary or tertiary WLC for lap's will need to be placed in the same mobility group. Now if you have a guest anchor controller for guest, then that will need to be added in the same mobility group. Bottom line, when users roam from AP to AP from WLC to another even getting tunneled (anchor) the WLC's need to be aware of the roaming and that is what mobility group does.
Anchor is if you want to tunnel users to a specific controller like in a guest wireless situation when the WLC is located in the DMZ. There are other reasons, but this is most likely why.

WLC MOBILITY GROUP SINGLE WEB AUTHENTICATION

Hi.
I have installed two AIR-WLC2112 with mobility group configured and authentication web.
I want to know if you can create user / password web authentication only in one WLC.
Now, when I create a new user / password , I have to create in two WLC.
Thanks

Inorder to validate a site issuing a certificate , client should be loaded with a certificate from same Certificate Authority. Else ignore the warning and continue to the site. If you want to know if the site is valid , click on View certificate on the warning page and see if it belongs to the website.

WLC Mobility Group problem

Hi to all,
we've two internal WLC which belong to the same MG (the default one), and one DMZ WLC which belongs to another MG.
All are running OS 4.2.61
After configuring Mobility Group using the "edit all" inserting the WLC IP address and MAC of the MGMT interface and the name of the MG which they belong, I notice a strange behaviour:
- WLC1 has Data path UP with internal's WLC2 and DMZ WLC...but Control path is down.
- WLC2 has Data path and Control path UP with DMZ WLC and only Data path UP with WLC1
- DMZ WLC has Data path and Control path UP with DMZ WLC and only Data path UP with WLC1
MG Secure Mode is disabled on all WLC's seeing the following bug CSCsk36683 (The mobility control path is down when secure mode is enabled).
Reachability via ping is OK, via eping the same but mping are not working from WLC1 to WCL2 and from DMZ WLC to WLC2
I've already restarted both controllers without success...what i've noticed is on WLC2 and DMZ WLC msglog there are a lot of these entries with a lot of RX errors ===>>>MM-3-INVALID_PKT_RECVD: Received an invalid packet from X.X.X.X. Source member:0.0.0.0. source member unknown.
any idea?
Tnx

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:

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
