Ing. Tag
Remove
Removes 802.3ac tag (or double tag) on tagged
ingressing frames.
Ingressing frames are
not modified.
Egr. Tag
Remove
Removes tag from egressing frames.
Frames are transmitted
unmodified.
Egr. Tag
Insert
Adds tag to
untagged
egressing frames (adds
the Default VLAN ID assigned to the port through
which the frame entered the switch).
Tagged
frames are not modified.
Frames are transmitted
unmodified.
Egr. Dbl.
Tag
Sup.
Double Tag support on Egress. When Egr. Tag
Insert is selected,
always
adds a tag on egress.
Tag will be added to both untagged frames and
to tagged frames (double tag).
No double tag support
on egress.
VLAN
Filtering
Filters frames for the VLAN membership of the
marked port.
Frames are received
unfiltered.
NOTES:
VLAN filtering operates on the port’s incoming and outgoing frames. A port whose VLAN
Filtering is enabled will only forward a frame if it is a tagged frame of the VLAN that the port
is a member of. A non-VLAN frame will be treated as if having the default VID of its ingress
port.
To avoid VLAN lockout, it is necessary to configure the VLAN membership (via the 802.1Q
VLANs tab) before enabling the VLAN filtering.
Frames without VLAN Tag or frames which their Tags are removed on Ingress (Ing. Tag
Remove) will be filtered (if the VLAN filtering is enabled on both the switch and the specific
port) according to the Default VLAN ID (Default VID) assigned to the originating port.
