14 Application examples • IEEE draft P802.1t/D10, November 20, 2000 Application examples Figure 110 shows an example of a network that uses GVRP. This section describes various ways you can use GVRP in a network such as this one. "CLI examples" on page 522 lists the CLI commands to implement the applications of GVRP described in this section. FIGURE 110 Example of GVRP Core Device Port2/1 Port4/1 Edge Device A Port1/24 Port4/24 Edge Device B Port6/24 Port4/1 Port8/17 Port2/24 Port4/24 Port4/1 Edge Device C Port2/24 Port4/24 In this example, a core device is attached to three edge devices. Each of the edge devices is attached to other edge devices or host stations (represented by the clouds). The effects of GVRP in this network depend on which devices the feature is enabled on, and whether both learning and advertising are enabled. In this type of network (a core device and edge devices), you can have the following four combinations: • Dynamic core and fixed edge • Dynamic core and dynamic edge • Fixed core and dynamic edge • Fixed core and fixed edge Dynamic core and fixed edge In this configuration, all ports on the core device are enabled to learn and advertise VLAN information. The edge devices are configured to advertise their VLAN configurations on the ports connected to the core device. GVRP learning is disabled on the edge devices. 506 PowerConnect B-Series FCX Configuration Guide 53-1002266-01
