By creating AP Groups you can control What SSIDs advertise on which APs, What dynamic interface map to each AP group (to reduce the broadcast size while having the same SSID). In latest codes of WLC software, via AP Group you can control RF profiles as well.Therefore you can have different RF characteristics to certain APs in your network.Also it supports 802.11u settings via AP Group. WLC code used in this post is 7.0.116.0.
You can create access point groups (AP Groups) and assign up to 16 WLANs to each group. Each access point advertises only the enabled WLANs that belong to its access point group. The access point does not advertise disabled WLANs in its access point group or WLANs that belong to another group.
You can create up to 50 access point groups for Cisco 2100 Series Controller and controller network modules; up to 300 access point groups for Cisco 4400 Series Controllers, Cisco WiSM, and 3750G wireless LAN controller switch; and up to 500 access point groups for Cisco 5500 Series Controllers.
By default there is a AP Group called “default-group” created on your WLC and all the WLANs where WLAN ID is between 1-16 map to this group. All the access points in the WLC also map to this group. This mean any WLAN (ID 1-16) will be available in any of the APs belong default group. If your WLAN ID is greater than 16, you have to create an AP group to advertise that WLAN (or SSID). Also if you want to advertize certain WLANs on particular APs (AP Group), you have to create an AP group for this.
Here is the topology for this post. 3502-a will be on AP group called “APG1” & 3502-d will be on “APG2” ap group. Both APs having 4402-c as primary controller & 4402-d as secondary controller. APG1 will map to vlan11 interface & APG2 will map to vlan12 interfaces on 4402-c (primary controller). In the event of AP fail-over to 4402-d (secondary controller) APG1 will map to vlan41 & APG2 will map to vlan42.
First we will create dynamic interfaces on 4402-c as shown below. Ensure that DHCP configured on the switch to support clients get dynamic IPs.
3750-b ip dhcp excluded-address 192.168.11.1 192.168.11.100 ip dhcp excluded-address 192.168.11.150 192.168.11.254 ip dhcp excluded-address 192.168.12.1 192.168.12.100 ip dhcp excluded-address 192.168.12.150 192.168.12.254 ip dhcp pool VLAN11 network 192.168.11.0 255.255.255.0 default-router 192.168.11.1 domain-name mrn.com ip dhcp pool VLAN12 network 192.168.12.0 255.255.255.0 default-router 192.168.12.1 domain-name mrn.com (4402-c) >config interface create vlan11 11 (4402-c) >config interface address dynamic-interface vlan11 192.168.11.33 255.255.255.0 192.168.11.1 (4402-c) >config interface dhcp dynamic-interface vlan11 primary 192.168.11.1 (4402-c) >config interface create vlan12 12 (4402-c) >config interface address dynamic-interface vlan12 192.168.12.33 255.255.255.0 192.168.12.1 (4402-c) >config interface dhcp dynamic-interface vlan12 primary 192.168.12.1
First we will create an WLAN called “wlan<16” (with WLAN ID 6). For simplicity we will disable the L2 security & make it open SSID. Other settings will be leave as default.
(4402-c) >config wlan create 6 wlan<16 wlan<16 (4402-c) >config wlan interface 6 vlan11 (4402-c) >config wlan security wpa disable 6 (4402-c) >config wlan enable 6
Now we will configure APG1 & APG2 & map interface vlan11 & vlan2 for the WLAN created.
(4402-c) >config wlan apgroup ? add Creates a new AP Group. delete Deletes a existing ap group. description Configures a description for an AP group. interface-mapping Adds or deletes a new apgroup/WLAN/interface mapping. nac-snmp Configures NAC SNMP functionality on given AP-Group. radio-policy Configures Radio Policy on given AP-Group. (4402-c) >config wlan apgroup add ? <apgroup name> Specify the name of the apgroup to configure. (4402-c) >config wlan apgroup add APG1 ? <description> (optional) Specify the description for the AP group. (4402-c) >config wlan apgroup add APG1 "AP Group 1" (4402-c) >config wlan apgroup add APG2 "AP Group 2" (4402-c) >config wlan apgroup interface-mapping ? add Adds a new apgroup/WLAN/interface mapping. delete Adds a new apgroup/WLAN/interface mapping. (4402-c) >config wlan apgroup interface-mapping add ? <apgroup name> Specify the name of the apgroup to configure. (4402-c) >config wlan apgroup interface-mapping add APG1 ? <WLAN or Remote LAN Id> Enter WLAN or Remote LAN Identifier between 1 and 512. (4402-c) >config wlan apgroup interface-mapping add APG1 6 ? <Interface Name> Specify the interface name. (4402-c) >config wlan apgroup interface-mapping add APG1 6 vlan11 (4402-c) >config wlan apgroup interface-mapping add APG2 6 vlan12
Then you can assign APs to AP group created as shown below.

You can check the connectivity by enabling 1 AP at a time to see correct IP range is given to user. First we will disable 3502-a & check the client IP once associated.

Let’s enable 3502-a & disable 3502-d. As you can see below since my client had vlan12 IP this time, client is moved to 3502-a without changing its IP.

But if you deauthenticate the client & forced to join again you will see client will get an vlan11 IP.

As you can see with AP group client will put in to configured vlans as they associate to network. But if they moved from an AP to another AP (in different AP group) client will keep the original IP address.
Now lets see how this works when AP fail-over to a secondary controller (4402-d).
3750-d interface Vlan41 ip address 192.168.41.1 255.255.255.0 ip helper-address 192.168.10.3 ! interface Vlan42 ip address 192.168.42.1 255.255.255.0 ip helper-address 192.168.10.3 (4402-d) >config interface create vlan41 41 (4402-d) >config interface address dynamic-interface vlan41 192.168.41.44 255.255.255.0 192.168.41.1 (4402-d) >config interface dhcp dynamic-interface vlan41 primary 192.168.10.3 (4402-d) >config interface create vlan42 42 (4402-d) >config interface address dynamic-interface vlan42 192.168.42.44 255.255.255.0 192.168.42.1 (4402-d) >config interface dhcp dynamic-interface vlan42 primary 192.168.10.3 (4402-d) >config wlan create 6 wlan<16 wlan<16 (4402-d) >config wlan interface 6 vlan41 (4402-d) >config wlan security wpa disable 6 (4402-d) >config wlan enable 6
Let’s configure the secondary controller for two APs.
(4402-c) >config ap secondary-base 4402-d 3502-a 192.168.40.44 (4402-c) >config ap secondary-base 4402-d 3502-d 192.168.40.44 (4402-c) >show ap config general 3502-a Cisco AP Identifier.............................. 4 Cisco AP Name.................................... 3502-a Country code.....................................

Now if you disconnect 4402-c (or shutdown G1/0/1-2) you will see two APs fail over to 4402-d.

Since we have not created any AP Group on secondary controller by default both ap will be put into default group. So client will be get vlan41 IPs as that is map to “wlan<16” WLAN.

Now let’s configure the two AP groups configured on 4402-c & see when fail-over occur those two AP goes into correct group as they were in the primary controller.
(4402-d) >config wlan apgroup add APG1 "AP Group 1" (4402-d) >config wlan apgroup add APG2 "AP Group 2" (4402-d) >config wlan apgroup interface-mapping add APG1 6 vlan41 (4402-d) >config wlan apgroup interface-mapping add APG2 6 vlan42
Now this time you can see 3502-a will go into APG1 where as 3502-d goes into APG2 as they were in the primary controller.

You can verify clients are getting vlan42 & vlan41 IP depend on where they are associated to (3502-d & 350-a respectively)

Therefore it is important to configure AP groups in all primary, secondary & tertiary controllers in a similar manner if you want to advertise same set of WLANs, map to required dynamic interface.
As an exercise you can try to use a WLAN ID greater than 16 (called “wlan>16”) & see how it works in a similar scenario.

Configure wlc using cli could be a challenge, if you are familiar with cisco ios, forget it, wlc is very different.
New wlc 5760 with ios xe is more friendly for cisco networkers.
I guest is a question of practice as rasika did when he passed cciew lab, so i have a lot of work in order to get confortable with wlc cli
great post.
Btw do you know how to configure a new default group? When I plug in a new AP in the network it goes to AP Group 1 and not to the default-group that have every ssid’s configured on the WLC?!
Cheers!
If it is a new AP it should go to default-group.
If this AP previously assign to APG1 then it will automatically goes to that AP group instead of default group.
HTH
Rasika
But Rasika, I will install 350 new AP’s and I want them to automatic join the “AP Group 1” and not the “default-group”.
can I set up “AP Group 1” as the default?
Hi Bruno,
There is no way you can set AP Group 1 as default AP Group.
You have to use either WLC GUI or CLI to do this.
If you have list of AP_Names then you can do it via CLI like below.
config ap group-name AP-Group1 AP_01
config ap group-name AP-Group1 AP_02
config ap group-name AP-Group1 AP_03
config ap group-name AP-Group1 AP_04
config ap group-name AP-Group1 AP_05
HTH
Rasika
Ok Rasika, glad to know. Thankyou very much!
HI
every where I search is about 4402! can you please show me the config about 5508?!! its very different and the problem Im having is the client stick to its IP address and it wont release it even if it is on different AP. I used the interface grouping in the SSID. can you please give me hint on this? its killing me
Are you talking about clinet roam to different AP (in different AP group), but still keep the same IP ?
That’s the normal behavior to support smooth roaming.
If new client associate to those AP in different AP group, then they will get different subnet IP if that configured. But if client roams he will retain original IP even it moved to different AP
HTH
Rasika
Well , here is the problem. I re-image 40 clients in IT room which is belong to AP with VLAN A. then after its done and update and everything I send them back to their original location to operate. In their location when they boot up they have to get an IP from VLAN B but they some how stick to their previous IP from range A. they are connected but its like they are on the roam state! Thanks for your help. this thing is putting me under massive work pressure .
Hi Rasika,
Is it possible to automatize the process of assigning an AP GROUP to each NEW AP?
For Example, all the new Outdoors AP I need it in the “Oudoor” AP Group, and all the Indoor AP in the “Indoor” AP Group.
I need to install 100 Outdoors AP (docsis and fiber) and it is very difficult to coordinate the work between the people who install it and configure ir.
Thanks for all!
Hi
I do not think there is an easy way of doing it.
But sometime using CLI may be faster than GUI configuration of this task. As long as you know the AP names you can assign them to required ap group. (below use Outdoor as AP Group name )
config ap group-name Outdoor AP-01
y
config ap group-name Outdoor AP-02
y
config ap group-name Outdoor AP-03

Hello
I’m writing this email asking for some info. By the way I’m still waiting for the eap debug u promised 🙂 Anyway I’ve got my ccna wireless yesterday. Im heading for ccnp cuwss which is a site survey. I’m wondering what sort of application and equipment u suggest me to buy for my home lab at this level. I don’t want to spent money with no reason and like to know your view I already have 3500 and 3700 ap. wlc 5508 and wcs. But im not sure what sort of software do i need for site survey I wil appreciate if u guide me about what I possibly need
Thanks and thanks and thanks for all your efforts Babak

Hi Babak,
As you know this year my focus shifted towards “inner peace” 🙂
So could not spend much time on blogging WiFi stuff. That’s the reason for not having that 3rd post on 802.1X.
Give some time, I will do this for you 🙂
Regarding your query for CUWSS, I have post a reply in CSC
https://supportforums.cisco.com/discussion/12605041/cuwss-home-lab-requirement
Hope that is useful
Rasika
Hi Rasika
Thanks for the reply and thanks for th einfo you posted on the Cisco forum for me.
By the way enjoy the ” inner peace” project but just to let you know you are hunted by the wireless topic! you are so deep into it that there is no way out for you. you will be back and I’ll wait 🙂
enjoy your time and thanks for everything
Great info, btw would like to ask, if i have two different AP group and i would like to create a SSID but using the same VLAN for both groups. Is it possible ?
Yes that is possible
Hi Rasika,
I need to clarify this. lets say I have 5 SSIDs in a AP group and 1 SSID is currently disabled. users are connecting to other 4 SSIDs.
Will there be any disconnection / interruption to the users connecting to other 4 SSIDs, If I need remove that disabled SSID from this AP group?
Thank you in advance for your support.
No, you should be fine with this
Hi, if a disable All 802.11a on my WLC, can I enable this feature on specific aps ??
Hi Joel
which feature you refer here ?
AP Group is always created, if you want to have set of APs to advertise particular SSIDs and have given RF settings

HI Rasika,
I have a lot of APs without Antennas of 5.0 Ghz, for that reason we have disable 802.11a in the wlc, my cuestion is..Can I create an AP Group like “Aps_with_antennas5.0” and enable only in that group the 802.11a ??
Thanks ¡¡¡
Yes that is possible, you hv a god use case to use “AP group”

Thats Good Rasika,
Can you share me any information about this kind of configuration ?? or features that I can check or uncheck on the Ap Group ??
Thanks ¡¡¡
Hi everyone,
i kinda understand AP groups but i am wondering which is the difference between them and interface groups. I asked also in Cisco forums but i don’t get the concepts.
Can you please clarify my doubts?
Thanks
Hi Michele,
Interface group is just combining multiple subnets to same WLAN. If you do not have continuous block of IP, then you can use interface group to add those discontinued subnets to same wlan.
AP Group is different where you can assign certain charateristics (subnet,RF charactersitics , wlan) to selected group of APs.

is there away on the 8540 controller, to set a time limit on an individual SSID of an AP group? if so can you walk me through it
I love your site. I come here whenever trying to find information about best practices. We have 37 access points and about 150 wireless clients. We work in a two-floor building and clients are mostly spread out. I have never used AP groups, but I am going to replace my controller soon so I am interested in them. If I wanted to add several AP groups for the sake of increasing WLAN performance, would it be worth the work?
Hi Aaron, Thank you for kind appreciation of my blog. AP group is useful if you want to selectively advertise SSID on certain APs (group of APs), control RF setting on those group and map users into different vlan based on AP group. If that is something you need go with AP groups
