Asymmetric VLAN Settings Shared VLAN Learning is a primary example of the requirement for Asymmetric VLANs. Under normal circumstances, a pair of devices communicating in a VLAN environment will both send and receive using the same VLAN; however, there are some circumstances in which it is convenient to make use of two distinct VLANs, one used for A to transmit to B and the other used for B to transmit to A in these cases Asymmetric VLANs are needed. An example of when this type of configuration might be required, would be if the client was on a distinct IP subnet, or if there was some confidentiality-related need to segregate traffic between the clients. To view this window click L2 Features > VLAN > Asymmetric VLAN Settings, as show below: Figure 4-10 Asymmetric VLAN Settings window Click Apply to implement changes. GVRP GVRP Global Settings Users can determine whether the Switch will share its VLAN configuration information with other GARP VLAN Registration Protocol (GVRP) enabled switches. In addition, Ingress Checking can be used to limit traffic by filtering incoming packets whose VID does not match the PVID of the port. Results can be seen in the table under the configuration settings. To view the following window, click L2 Features > VLAN > GVRP > GVRP Global Settings, as show below: Figure 4-11 GVRP Global Settings window The fields that can be configured are described below: 71
