This document describes how to configure multiple service set identifiers (SSIDs) with multiple VLANs on Cisco IOS? software and autonomous Cisco Aironet Access Points.
This configuration example assumes you have configured the DHCP pool on the Cisco IOS switch or router or on a dedicated DHCP server.
In order to complete this configuration, Cisco recommends that you have basic knowledge of Cisco IOS CLI commands.
Any switch that runs Cisco IOS and supports Multilayer Switching (MLS)
Cisco Aironet Access Points
The SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a network or subnetwork can use the same SSIDs. SSIDs are case sensitive and can contain up to 32 alphanumeric characters. Do not include spaces in your SSIDs.
You can configure up to 16 SSIDs on your Cisco Aironet 1200 Series Access Point and assign different configuration settings to each SSID. All the SSIDs are active at the same time; that is, client devices can associate to the access point using any of the SSIDs.
If you want the access point to allow associations from client devices that do not specify an SSID in their configurations, you can set up a guest SSID. The access point includes the guest SSID in its beacon. The access point's default SSID, tsunami, is set to guest mode. However, to keep your network secure, you should disable the guest mode SSID on most access points.
If your access point will be a repeater or will be a root access point that acts as a parent for a repeater, you can set up an SSID for use in repeater mode. You can assign an authentication username and password to the repeater-mode SSID to allow the repeater to authenticate to your network like a client device.
If your network uses VLANs, you can assign one SSID to a VLAN. Client devices that use the SSID are grouped in that VLAN.
This video shows the configuration described in this document:
This configuration uses VLANs (1, 2, and 3) with native as V:LAN 1 and mapping to 3 different SSIDs (ONE , TWO, and THREE) on any Cisco Aironet Access Point.
SSID ONE uses WEP encryption.
SSID TWO uses WPA-PSK.
SSID THREE uses WPA-2-PSK.
Assuming the AP Ethernet port is connected to fa 2/1 port of the switch.
Broadcasting all 3 SSIDs.
If you use a single SSID, use the guest-mode command under the SSID.
If you use multiple SSIDs, use the mbssid command under the SSID and under Radio Interfaces
