Put all of your AP's in one big AP Group.


Depend on your firmware.

Put the 7 AP's you want to broadcast the four SSID in an AP Group (in later version AP Group has been replaced with HREAP Group ... I think).

Hi Marvin,


Just to add a note to the great tips from my friend Leo +5 points Leo :) You would want the 7 Ap's in a AP Group that pushes out all the SSID's and the single AP in a Group that pushes out selected SSID's;


Creating Access Point Groups


After all access points have joined the controller, you can create up to 150 access point 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.


Using the CLI to Create Access Point Groups


Using the controller CLI, follow these steps to create access point groups.



Step 1 To create an access point group, enter this command:


config wlan apgroup add group_name





Note To delete an access point group, enter this command: config wlan apgroup delete group_name. A warning message appears if you try to delete an access point group that is used by at least one access point. If you proceed, any access points assigned to this access point group are moved to the default-group access point group.



Step 2 To add a description to an access point group, enter this command:


config wlan apgroup description group_name description


Step 3 To assign a WLAN to an access point group, enter this command:


config wlan apgroup interface-mapping add group_name wlan_id interface_name





Note To remove a WLAN from an access point group, enter this command: config wlan apgroup interface-mapping delete group_name wlan_id.



Step 4 To enable or disable NAC out-of-band support for this access point group, enter this command:


config wlan apgroup nac {enable | disable} group_name wlan_id


Step 5 To assign an access point to an access point group, enter this command:


config ap group-name group_name Cisco_AP





Note To remove an access point from an access point group, re-enter this command and assign the access point to another group.



Step 6 To save your changes, enter this command:


save config



....continued on next page.

Using the GUI to Create Access Point Groups


Using the controller GUI, follow these steps to create an access point group.



Step 1 Click WLANs > Advanced > AP Groups to open the AP Groups page


Step 2 Click Add Group to create a new access point group. The Add New AP Group section appears at the top of the page.


Step 3 In the AP Group Name field, enter the group's name.


Step 4 In the Description field, enter the group's description.


Step 5 Click Add. The newly created access point group appears in the list of access point groups on the AP Groups page.





Note If you ever want to delete this group, hover your cursor over the blue drop-down arrow for the group and choose Remove. A message appears asking you to confirm your decision. If you proceed, any access points assigned to this access point group are moved to the default-group access point group.



Step 6 To edit this new group, click the name of the group. The AP Groups > Edit (General) page appears


Step 7 To change the description of this access point group, enter the new text in the AP Group Description field and click Apply.


Step 8 Click the WLANs tab to open the AP Groups > Edit (WLANs) page. This page lists the WLANs that are currently assigned to this access point group.


Step 9 Click Add New to assign a WLAN to this access point group. The Add New section appears at the top of the page


Step 10 From the WLAN SSID drop-down box, choose the SSID of the WLAN.


Step 11 From the Interface Name drop-down box, choose the interface to which you want to map the access point group. Choose the quarantine VLAN if you plan to enable network admission control (NAC) out-of-band support.




Note The interface name in the default-group access point group matches the WLAN interface.



Step 12 To enable NAC out-of-band support for this access point group, check the NAC State check box. To disable NAC out-of-band support, leave the check box unchecked, which is the default value. Refer to the "Configuring NAC Out-of-Band Integration" section for more information on NAC.


Step 13 Click Add to add this WLAN to the access point group. This WLAN appears in the list of WLANs that are assigned to this access point group.




Note If you ever want to remove this WLAN from the access point group, hover your cursor over the blue drop-down arrow for the WLAN and choose Remove.



Step 14 Repeat Step 9 through Step 13 to add any additional WLANs to this access point group.


Step 15 Click the APs tab to assign access points to this access point group. The AP Groups > Edit (APs) page lists the access points that are currently assigned to this group as well as any access points that are available to be added to the group. If an access point is not currently assigned to a group, its group name appears as "default-group"


Step 16 To add an access point to this access point group, check the check box to the left of the access point name and click Add APs. The access point now appears in the list of access points currently in this access point group.




Note To select all of the available access points at once, check the AP Name check box. All of the access points are then selected.





Note If you ever want to remove an access point from the group, check the check box to the left of the access point name and click Remove APs. To select all of the access points at once, check the AP Name check box. All of the access points are then removed from this group.




Step 17 Click Save Configuration to save your changes.

Make sure that you have applied the ap group on the ap... both radios. Default-Group is the default set on the ap's which will broadcast all ssid's configured on the wlc.

So Galeria is beaconing all ssid's configured? Is it on the 2.4ghz and 5ghz?

I have a few question RE: this feature.


What device keeps the AP group assignment? I know the mapping of groups is in the controller but does the AP have the name of the group that it is a member of in its configuration? What happens when this AP attaches to another controller? Will the group maping still work if the other controller has the sam AP group name?


How do you account for which AP's are assigned to what groups? Is there a report you can run to see the members of each group?


Is there place to configure the AP group in the WCS or do you have to configure this directly on each controller?

Unless you have a WCS and configured AP Group/HREAP Group via the WCS, you'll need to configure the AP Group/HREAP Group on all the WLC if you don't have a WCS.

Hello people, finally I opened a case with TAC and the answer was very simple:


In the Wireless Controller go to Wireless Option, then choose the AP that you want to restrict the SSID, then go to left panel option Radio and choose whether 802.11a/n or 802.11b/g/n. Then go to the right panel and put your mouse over the blue arrow that select your AP and a hide menu will appear, then choose configure and a new configuration screen apear where the option WLAN override exist. What you only need to do is enable this option and the list of all SSID that you want to active in this AP will appear. Once you select the SSID you need to apply and restar the AP.

Thanks all of you for your reply to this post.
