DGS-3024 Gigabit Ethernet Switch Manual 
Frame Type 
This field denotes the type of frame that will be accepted by the port. The user may 
choose between Tagged Only, which means only VLAN tagged frames will be 
accepted, and Admit_All, which means both tagged and untagged frames will be 
accepted. Admit_All is enabled by default. 
PVID 
This field in the 802.1Q Port Table shows the current PVID assignment for each 
port, which may be manually assigned to a VLAN when created in the 802.1Q Port 
Settings table. The Switch's default is to assign all ports to the default VLAN with a 
VID of 1.The PVID is used by the port to tag outgoing, untagged packets, and to 
make filtering decisions about incoming packets. If the port is specified to accept 
only tagged frames - as tagging, and an untagged packet is forwarded to the port 
for transmission, the port will add an 802.1Q tag using the PVID to write the VID in 
the tag. When the packet arrives at its destination, the receiving device will use the 
PVID to make VLAN forwarding decisions. If a packet is received by the port, and 
Ingress filtering is Enabled, the port will compare the VID of the incoming packet to 
its PVID. If the two are unequal, the port will drop the packet. If the two are equal, 
the port will receive the packet. 
GVRP 
The Group VLAN Registration Protocol (GVRP) enables the port to dynamically 
become a member of a VLAN. GVRP is Disabled by default.
