Configuring AAA for network users 471Nortel WLAN—Security Switch 2300 Series Configuration GuideLast-resort access to an SSID does not require a special user (such as last-resort-ssid) to beconfigured. Instead, if the fallthru authentication type on the SSID’s service profile is set tolast-resort, and the SSID does not have any 802.1X or MAC access rules, a user can access theSSID without entering a username or password.If the user is authenticated, WSS Software then checks the RADIUS server or local database (the same placeWSS Software looked for user information to authenticate the user) for the authorization attributes assigned tothe 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 WSSSoftware have additional optional attributes. For example, you can provide further access controls by speci-fying the times during which the user can access the network, you can apply inbound and outbound accesscontrol 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. Toassign attributes in the WSS’s local database, use the WSS Software vendor-specific attributes (VSAs).The RADIUS attributes supported by WSS Software are described in “Supported RADIUS attributes”(page 697).WSS Software provides the following VSAs, which you can assign to users configured in the local database oron a RADIUS server:• Encryption-Type—Specifies the type of encryption required for access by the client. Clients who attemptto 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 ports a user can access. For wireless users, a WSS SoftwareMobility Profile specifies the APs through which the user can access the network. For wiredauthentication users, the Mobility Profile specifies the wired authentication ports through which the usercan 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 doesnot authenticate the user unless the attempt to access the network occurs at or after the specified date andtime, 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.• Service-Type—Type of access the user is requesting, which can be network access, administrative accessto the enabled (configuration) mode of the WSS Software CLI, or administrative access to the nonenabledmode 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.In addition to configuring authorization attributes for users on RADIUS servers or the switch’s local database,you can also configure attributes within a service profile. These authorization attributes are applied to users.No.
