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.

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 PVID does not match the PVID of the port. Results can be seen in the table under the
configuration settings.
