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 255 VLANs, but up to 4094 VLANs are supported by the 
IEEE 802.1Q VLAN protocol. 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 2-41 or page 3-28).

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 the Layer-3 switch (such as the ES3616) or router.
