Authorization - Nortel 2300 Series Configuration Manual

408 Configuring AAA for Network Users

Authorization

If the user is authenticated, WSS Software then checks the RADIUS server or local database (the same place WSS
Software looked for user information to authenticate the user) for the authorization attributes assigned to the user.
Authorization attributes specify the network resources the user can access.
The only required attribute is the Virtual LAN (VLAN) name on which to place the user. RADIUS and WSS Software
have additional optional attributes. For example, you can provide further access controls by specifying the times during
which the user can access the network, you can apply inbound and outbound access control lists (ACLs) to the user's
traffic, and so on.
To assign attributes on the RADIUS server, use the standard RADIUS attributes supported on the server. To assign
attributes in the WSS switch's local database, use the WSS Software vendor-specific attributes (VSAs).
The RADIUS attributes supported by WSS Software are described in
WSS Software provides the following VSAs, which you can assign to users configured in the local database or on a
RADIUS server:
• Encryption-Type—Specifies the type of encryption required for access by the client. Clients who attempt to use an
unauthorized encryption method are rejected.
• End-Date—Date and time after which the user is no longer allowed to be on the network.
• Mobility-Profile—Controls the WSS switch ports a user can access. For wireless users, an WSS Software Mobility
Profile specifies the AP access ports through which the user can access the network. For wired authentication users,
the Mobility Profile specifies the wired authentication ports through which the user can access the network.
• SSID—SSID the user is allowed to access after authentication.
• Start-Date—Date and time at which the user becomes eligible to access the network. WSS Software does not
authenticate the user unless the attempt to access the network occurs at or after the specified date and time, but
before the end-date (if specified).
• Time-of-Day—Day(s) and time(s) during which the user is permitted to log into the network.
• URL—URL to which the user is redirected after successful Web-based AAA.
• VLAN-Name—VLAN to place the user on.
You also can assign the following RADIUS attributes to users configured in the local database.
• Filter-Id—Security ACL that permits or denies traffic received (input) or sent (output) the WSS switch.
• Service-Type—Type of access the user is requesting, which can be network access, administrative access to the
enabled (configuration) mode of the WSS Software CLI, or administrative access to the nonenabled mode of the
CLI
• Session-Timeout—Maximum number of seconds allowed for the user's session.
Regardless of whether you configure the user and attributes on RADIUS servers or the switch's local database, the
VLAN attribute is required. The other attributes are optional.
