460CHAPTER 21: CONFIGURING AAA FOR NETWORK USERS

Configuring Web WebAAA simplifies secure access to unencrypted SSIDs. When a user

Portal WebAAA requests access to an SSID or attempts to access a web page before logging onto the network, MSS serves a login page to the user’s browser. After the user enters a username and password, MSS checks the local database or RADIUS servers for the user information, and grants or denies access based on whether the user information is found.

MSS redirects an authenticated user back to the requested web page, or to a page specified by the administrator.

WebAAA, like other types of authentication, is based on an SSID or on a wired authentication port.

You can use WebAAA on both encrypted and unencrypted SSIDs. If you use WebAAA on an encrypted SSID, you can use static WEP or WPA with PSK as the encryption type.

MSS provides a 3Com login page, which is used by default. You can add custom login pages to the WX switch’s nonvolatile storage, and configure MSS to serve those pages instead.

Web Portal WebAAA replaces the WebAAA implementation in MSS Version 3.x. The previous implementation is deprecated beginning in MSS Version 4.0. During upgrade from MSS Version 3.x, your 3.x WebAAA configuration is automatically converted to a Web Portal WebAAA configuration.

How WebAAA Portal

Works

1A WebAAA user attempts to access the network. For a wireless user, this begins when the user’s network interface card (NIC) associates with an SSID on a 3Com radio. For a wired authentication user, this begins when the user’s NIC sends data on the wired authentication port.

2MSS starts a portal session for the user, and places the user in a VLAN.

„If the user is wireless (associated with an SSID), MSS assigns the user to the VLAN set by the vlan-name attribute for the SSID’s service profile.

„If the user is on a wired authentication port, the VLAN is the one assigned to the web-portal-wireduser.
