Configuring Web 
Portal WebAAA
WebAAA simplifies secure access to unencrypted SSIDs. When a user 
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
A 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. 
2
MSS 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-wired
 
user
