This allows GVRP-compliant devices to be automatically configured for VLAN groups based solely on endstation requests.

Forwarding Traffic with Unknown VLAN Tags

This switch only supports 256 VLANs with VLAN IDs ranging from 1 to 2048, but the IEEE 802.1Q VLAN standard allows for VLAN IDs from 1 to 4094. Therefore, if this switch is attached to endstations that issue VLAN registration requests, it will have to forward unknown VLAN tags. This traffic can only be propagated to the rest of the network if automatic VLAN registration is enabled on your switch.

Forwarding Tagged/Untagged Frames

Ports can be assigned to multiple tagged or untagged VLANs. Each port on the switch is therefore capable of passing tagged or untagged frames. To forward a frame from a VLAN-aware device to a VLAN-unaware device, the switch first decides where to forward the frame, and then strips off the VLAN tag. However, to forward a frame from a VLAN-unaware device to a VLAN-aware device, the switch first decides where to forward the frame, and then inserts a VLAN tag reflecting this port’s default VID. The default PVID is VLAN 1 for all ports, but this can be changed (see page 2-48or page 3-30).

Connecting VLAN Groups

The switch supports intra-VLAN communication using wire-speed switching. However, if you have devices in separate VLANs that must communicate, and it is not practical to include these devices in a common VLAN, then the VLANs can be connected via a Layer 3 switch or router.
