DGS-3048 Gigabit Ethernet Switch Manual

Parameter Description

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.

Link Aggregation

Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline.

The DGS-3048 supports up to four port trunk groups with 2 to 8 ports in each group. A potential bit rate of 8000 Mbps can

be achieved.
