From...To These two fields allow you to specify the range of ports that will be included in the Port-based VLAN
that you are creating using the 802.1Q Port Settings window.
PVID The read-only 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 - and the tagging packet is forwarded to the port
for transmission, then the untagged packets will be dropped. When the packet arrives at its
destination, the receiving device will use the PVID to make VLAN forwarding decisions. If the port
receives a packet, 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 GARP VLAN Registration Protocol (GVRP) enables the port to dynamically become a member
of a VLAN. GVRP is Disabled by default.
This field can be toggled using the space bar between Enabled and Disabled. Enabled enables the
Ingress
Check port to compare the VID tag of an incoming packet with the PVID number assigned to the port. If the
two are different, the port filters (drops) the packet. Disabled disables ingress filtering. Ingress
Checking is Enabled by default.
Acceptable This field denotes the type of frame that will be accepted by the port. The user may choose between
Frame Tagged Only, which means only VLAN tagged frames will be accepted, and Admit_All, which mean
Type both tagged and untagged frames will be accepted. Admit_All is enabled by default.
