Figure 3-1 displays multiple BlackDiamonds being used by an Ethernet Service Provider
to provide point-to-point connectivity between their customer's Ethernet networks
using ATM PVCs. In this example, CustomerA has an Ethernet network in two different
locations, one connected to BlackDiamond switch 1 via port 1:1 and the other connected
to BlackDiamond switch 2 via port 8:1. Similarly, CustomerB is connected to
BlackDiamond switch 1 via port 1:16 and BlackDiamond switch 3 via port 8:1. On
BlackDiamond switch 1, the service provider has configured PVC 5/101 on ATM port
8:1 to connect to BlackDiamond switch 2 and PVC 5/102 on ATM port 8:1 to connect to
BlackDiamond switch 3. The following configuration commands describe the basic steps
necessary to configure the network displayed in Figure 3-1.
