Bind to All 802.1Q
Multi-
layer
Ingress: Untagged frames are classified to the VLAN
associated with the port on which the frame is
received. Tagged frames are classified to the VLAN
identified by the VLAN tag in the tag header of the
frame.
Note: For 802.1q mode: if a tagged frame is received,
but the VLAN for that tagged frame does not
exist on the switch, that frame will placed onto
the port VLAN assigned to the port. This may
cause unicast and broadcast VLAN traffic from
other VLANs to be seen on the port VLAN. To
avoid this behavior, you can set the port VLAN
into the “discard” VLAN which will drop all
untagged frames and tagged frames with
unknown VLAN IDs. For Multi-layer and
3Com mode: if a tagged frame is received, but
the VLAN for that tagged frame does not exists
on the switch, that frame will be dropped.
Forwarding: All broadcast frames from all VLANs will
be forwarded to the port.
Egress: All frames transmitted out of the port to be
tagged using the IEEE 802.1Q/Multi-Layer tag header
format. The tagged used will be that of the VLAN in
which the frame was received.
Bind to Received Clear NOT RECOMMENDED
Ingress: Untagged frames are classified to the VLAN
associated with the port on which the frame is
received. Tagged frames are classified to the VLAN
identified by the VLAN tag in the tag header of the
frame.
Forwarding: All broadcast frames from all VLANs
learned on the port will be forwarded.
Egress: All frames transmitted will be sent with no
tagging.
