If your network includes a Passport 6400, the Passport 6400 can be configured to provide inter-LAN switching (ILS) service for the network. The Passport 4400 uses switched permanent virtual circuits (SPVCs) to establish connections to the Passport 6400. These SPVCs provide the Passport 4400 with access to higher-level LAN protocols that provide routing and other LAN services.
|
Note: Switched permanent virtual circuit (SPVC) refers to a connection between a Passport 4400 unit and a Passport 6400 unit, or between two Passport 4400 units. SPVCs eliminate the need to configure each node along the connection. The end point is configured, but the connection route is selected automatically. |
In addition, the Passport 6400 can serve as the UCR or network management core
router for internetworking Passport 4400 nodes. For more information on ILS
and the Passport 6400, see
