STEP 3
Enter the values for the following fields:

—Select a VLAN to be defined as the primary VLAN in the private
VLAN. The primary VLAN is used to allow Layer 2 connectivity from promiscuous
ports to isolated ports and to community ports.

Isolated VLAN ID
—An isolated VLAN is used to allow isolated ports to send traffic
to the primary VLAN.
•
Available Community VLANs
—Move the VLANs that you want to be community
VLANs to the
Selected Community VLANs

allow Layer 2 connectivity from community ports to promiscuous ports and to
community ports of the same community. This is called

the main page.

GVRP Settings
Adjacent VLAN-aware devices can exchange VLAN information with each other by using the
Generic VLAN Registration Protocol (GVRP). GVRP is based on the Generic Attribute
Registration Protocol (GARP) and propagates VLAN information throughout a bridged
network.
To enable GVRP on an interface, it must be configured in General mode.
When a port joins a VLAN by using GVRP, it is added to the VLAN as a tagged dynamic
member, unless this was expressly forbidden in the
page. If the
VLAN does not exist, it is dynamically created when Dynamic VLAN creation is enabled for
this port (in the
page).
