Ingress Filter on the switch.
Web-Based Network Management
Description
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 as tagging, and an
untagged packet if 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.
Shows the current PVID assignment for
each port. The switch' s default is to
assign all ports to the Default_VLAN with
a VID of 1.
