PVID A PVID (Port VLAN ID) is a tag that adds to incoming untagged packets received
on a port so that the packets are forwarded to the VLAN group that the tag
defines. Enter a number between 1and 4094 as the port VLAN ID.
Priority Enter a priority level (1~7) that the BM2022w assigns to packets belonging to
this VLAN. Enter “0” for no priority assigned.
CFI Select Yes if the CFI (Canonical Format Indicator) field in a received packet is
set to 1, indicating non-Canonical Format. In this case, the packet should not be
forwarded as it is to an untagged port.
Tag/Untag You can only select Tag if the port is configured as a Trunk or Hybrid port. The
BM2022w will receive and forward VLAN tagged packets. Untagged packets will
be tagged with the PVID.
If you select Untag the BM2022w will remove tags from tagged packets it
forwards out of the port. Untagged packets received will be forwarded. If the
port is an Access port, the BM2022w will add tags to untagged packets it
receives and drop tagged packets it receives. If the port is a Trunk port, the
BM2022w will add tags to untagged packets it receives and retag tagged
packets.
