Dynamic Core And Dynamic Edge - Dell PowerConnect B-FCXs Configuration Manual

Core device
•
•
NOTE: Since learning is
In this configuration, the edge devices are statically (manually) configured with VLAN information.
The core device dynamically configures itself to be a member of each of the edge device VLANs.
The operation of GVRP on the core device results in the following VLAN configuration on the device:
•
•
•
VLAN 20 traffic can now travel through the core between edge devices A and B. Likewise, VLAN 30
traffic can travel between B and C and VLAN 40 traffic can travel between A and C. If an edge
device is moved to a different core port or the VLAN configuration of an edge device is changed, the
core device automatically reconfigures itself to accommodate the change.
Notice that each of the ports in the dynamically created VLANs is tagged. All GVRP VLAN ports
configured by GVRP are tagged, to ensure that the port can be configured for additional VLANs.
NOTE
This example assumes that the core device has no static VLANs configured. However, you can have
static VLANs on a device that is running GVRP. GVRP can dynamically add other ports to the statically
configured VLANs but cannot delete statically configured ports from the VLANs.

Dynamic core and dynamic edge

GVRP is enabled on the core device and on the edge devices. This type of configuration is useful if
the devices in the edge clouds are running GVRP and advertise their VLANs to the edge devices.
The edge devices learn the VLANs and also advertise them to the core. In this configuration, you do
not need to statically configure the VLANs on the edge or core devices, although you can have
statically configured VLANs on the devices. The devices learn the VLANs from the devices in the
edge clouds.
