How to Configure Access Point Groups

Switch# configure terminal

Switch(config)# ap group my-ap-group

Switch(config-apgroup)# wlan wlan-name

Switch(config-apgroup)# vlan test-vlan

Switch(config)# end

Switch# configure terminal
Switch(config-apgroup)# ap group test-ap-group-16
Switch(config-wlan-apgroup)# wlan test-ap-group-16
Switch(config-wlan-apgroup)# vlan VLAN1300             

Switch# ap name 1240-101 ap-groupname apgroup_16

Switch# show ap groups

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the Feature Information Table at the end of this document.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to http:/​/​www.cisco.com/​go/​cfn. An account on Cisco.com is not required.

Prerequisites for Configuring AP Groups

The following are the prerequisites for creating access point groups on a switch:

• The required access control list (ACL) must be defined on the router that serves the VLAN or subnet.
• Multicast traffic is supported with access point group VLANs. However, if the client roams from one access point to another, the client might stop receiving multicast traffic, unless IGMP snooping is enabled.

Restrictions for Configuring Access Point Groups

• Suppose that the interface mapping for a WLAN in the AP group table is the same as the WLAN interface. If the WLAN interface is changed, the interface mapping for the WLAN in the AP group table also changes to the new WLAN interface. Suppose that the interface mapping for a WLAN in the AP group table is different from the one defined for the WLAN. If the WLAN interface is changed, then the interface mapping for the WLAN in the AP group table does not change to the new WLAN interface.
• If you clear the configuration on the switch, all of the access point groups disappear except for the default access point group “default-group,” which is created automatically.
• The default access point group can have up to 16 WLANs associated with it. The WLAN IDs for the default access point group must be less than or equal to 16. If a WLAN with an ID greater than 16 is created in the default access point group, the WLAN SSID will not be broadcasted. All WLAN IDs in the default access point group must have an ID that is less than or equal to 16. WLANs with IDs greater than 16 can be assigned to custom access point groups.

Information About Access Point Groups

After you create up to 512 WLANs on the switch, you can selectively publish them (using access point groups) to different access points to better manage your wireless network. In a typical deployment, all users on a WLAN are mapped to a single interface on the switch. Therefore, all users that are associated with that WLAN are on the same subnet or VLAN. However, you can choose to distribute the load among several interfaces or to a group of users based on specific criteria such as individual departments (such as Marketing) by creating access point groups. Additionally, these access point groups can be configured in separate VLANs to simplify network administration.

How to Configure Access Point Groups

Creating Access Point Groups

Before You Begin

You must have administrator privileges to perform this operation.

SUMMARY STEPS

1.    configure terminal


2.    ap group ap-group-name


3.    wlan wlan-name


4.    (Optional) vlan vlan-name


5.    end

DETAILED STEPS

	Command or Action	Purpose
Step 1	configure terminal Example: Switch# configure terminal	Enters global configuration mode.
Step 2	ap group ap-group-name Example: Switch(config)# ap group my-ap-group	Creates an access point group.
Step 3	wlan wlan-name Example: Switch(config-apgroup)# wlan wlan-name	Associates the AP group to a WLAN.
Step 4	vlan vlan-name Example: Switch(config-apgroup)# vlan test-vlan	(Optional) Assigns the access point group to a VLAN.
Step 5	end Example: Switch(config)# end	Returns to privileged EXEC mode. Alternatively, you can also press Ctrl-Z to exit global configuration mode.

This example shows how to create an AP group:

Switch# configure terminal
Switch(config-apgroup)# ap group test-ap-group-16
Switch(config-wlan-apgroup)# wlan test-ap-group-16
Switch(config-wlan-apgroup)# vlan VLAN1300

Assigning an Access Point to an AP Group

Before You Begin

SUMMARY STEPS

1.    ap name ap-name ap-group-name ap-group

DETAILED STEPS

	Command or Action	Purpose
Step 1	ap name ap-name ap-group-name ap-group Example: Switch# ap name 1240-101 ap-groupname apgroup_16	Assigns the access point to the access point group. The keywords and arguments are as follows: name—Specifies that the argument following this keyword is the name of an AP that is associated to the switch. ap-name—AP that you want to associate to the AP group. ap-group-name—Specifies that the argument following this keyword is the name of the AP group that is configured on the switch. ap-group—Name of the access point group that is configured on the switch.
