Hi Roberto,

You can configure up to 16 SSIDs on your access point/bridge 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/bridge using any of the SSIDs. These are the settings you can assign to each SSID:

•VLAN

•Client authentication method

--------------------------------------------------------------------------------

Note For detailed information on client authentication types, see "Configuring Authentication Types."

--------------------------------------------------------------------------------

•Maximum number of client associations using the SSID

•RADIUS accounting for traffic using the SSID

•Guest mode

•Repeater mode, including authentication username and password

•Redirection of packets received from client devices

Hope this helps!
