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. 

Click Apply to implement changes made.
