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.
