14-12 Remote Node Configuration
Do not edit filter sets 11 and 12. They are used exclusively by the web
configurator. Any rules you configured in sets 11 and 12 will be erased and
replaced when you apply the web configurator-generated filter rules.
14.6 Editing ATM Layer Options
Follow the steps shown next to edit Menu 11.6 – Remote Node ATM Layer Options .
In menu 11.1, move the cursor to the Edit ATM Options field and then press [SPACE BAR] to select
Yes . Press [ENTER] to display Menu 11.6 – Remote Node ATM Layer Options .
There are two versions of menu 11.6 for the Prestige, depending on whether you chose VC-based / LLC-
based multiplexing and PPP encapsulation in menu 11.1.
14.6.1 VC-based Multiplexing (non-PPP Encapsulation)
For VC-based multiplexing, by prior agreement, a protocol is assigned a specific virtual circuit, for
example, VC1 will carry IP. Separate VPI and VCI numbers must be specified for each protocol.
Figure 14-11 Menu 11.6 for VC-based Multiplexing
14.6.2 LLC-based Multiplexing or PPP Encapsulation
For LLC-based multiplexing or PPP encapsulation, one VC carries multiple protocols with protocol
identifying information being contained in each packet header.
