Chapter 24 AAA Table 86 Advanced Application > AAA > AAA Setup (continued) LABEL Method DESCRIPTION Select whether you want to use RADIUS or TACACS+ for authorization of specific types of events. Accounting Update Period Type RADIUS is the only method for IEEE 802.1x authorization. Use this section to configure accounting settings on the Switch. This is the amount of time in minutes before the Switch sends an update to the accounting server. This is only valid if you select the start-stop option for the Dot1x entry. The Switch supports the following types of events to be sent to the accounting server(s): • System - Configure the Switch to send information when the following system events occur: system boots up, system shuts down, system accounting is enabled, system accounting is disabled Active Broadcast • Dot1x - Configure the Switch to send information when an IEEE 802.1x client begins a session (authenticates via the Switch), ends a session as well as interim updates of a session. Select this to activate accounting for a specified event types. Select this to have the Switch send accounting information to all configured accounting servers at the same time. Mode If you don't select this and you have two accounting servers set up, then the Switch sends information to the first accounting server and if it doesn't get a response from the accounting server then it tries the second accounting server. The Switch supports two modes of recording login events. Select: • start-stop - to have the Switch send information to the accounting server when a user begins a session, during a user's session (if it lasts past the Update Period), and when a user ends a session. Method • stop-only - to have the Switch send information to the accounting server only when a user ends a session. Select whether you want to use RADIUS or TACACS+ for accounting of specific types of events. Apply Cancel TACACS+ is the only method for recording s type of event. Click Apply to save your changes to the Switch's run-time memory. The Switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the non-volatile memory when you are done configuring. Click Cancel to begin configuring this screen afresh. 24.6 Technical Reference This section provides technical background information on the topics discussed in this chapter. 24.6.1 Vendor Specific Attribute RFC 2865 standard specifies a method for sending vendor-specific information between a RADIUS server and a network access device (for example, the Switch). A company can create Vendor Specific Attributes (VSAs) to expand the functionality of a RADIUS server. The Switch supports VSAs that allow you to perform the following actions based on user authentication: GS1920 Series User's Guide 196
