Configuring AAA for Network Users 431
Nortel WLAN Security Switch 2300 Series Configuration Guide
The web ACL is created automatically by WSS Software, and has the following ACEs:
set security acl ip portalacl.in permit udp 0.0.0.0 255.255.255.255 eq 68 0.0.0.0
255.255.255.255 eq 67
set security acl ip portalacl.in deny 0.0.0.0 255.255.255.255 capture
For wired authentication ports, create a web-portal-wired user and configure the VLAN-Name and
Filter-Id attributes as described above. The VLAN-Name must be the user’s VLAN and the Filter-Id
attribute must map the web ACL created by WSS Software to the inbound traffic direction.
• Web-based AAA users—Information for the username that will be entered for login must be configured in the local
database or on a RADIUS server. You can configure authorization attributes for the Web-based AAA user.
However, the VLAN-Name or Tunnel-Private-Group-ID attribute is ignored. The optional VSAs include url,
which redirects an authenticated user to a URL other than the one they were attempting to access when they logged
on.
To configure user information in the local database, use the set user and set user username attr
commands. To configure user groups and set attributes on a group basis, use the set user username group
and set usergroup commands.
• Authentication rules—A last-resort authentication rule must be configured for each web-portal-ssid user and the
web-portal-wired user, if configured. The last-resort rule specifies the authentication method (local database or
RADIUS server group) to use for the part of the session during which the user is waiting to be authenticated and
authorized.
In addition, a web authentication rule must be configured for the Web-based AAA users. Whereas the
last-resort rule matches on the web-portal-ssid or web-portal-wired user, the web rule must match on
the username the Web-based AAA user will enter on the Web-based AAA login page. The web rule also
must match on the SSID the user will use to access the network. If the user will access the network on a
wired authentication port, the rule must match on wired.
To configure authentication rules, use the set authentication web and set authentication last-resort
commands.
• Portal Web-based AAA must be enabled, using the set web-aaa command. The feature is enabled by default.
Caution! If you do not use the Filter-Id attribute to map the portal ACL to the inbound
traffic direction of the web-portal-ssid and web-portal-wired users, the Web-based AAA
users are placed into the VLAN associated with the web-portal-ssid or web-portal-wired
user, without any filters.
Note. Portal Web-based AAA does not assign a user to a VLAN based on the
VLAN-Name or Tunnel-Private-Group-ID authorization attribute set for the user. WSS
Software ignores these attributes and leaves the user in the VLAN assigned to the
web-portal-ssid or web-portal-wired user.
