 Unaware: indicates that port will operate as unaware in
the ingress process. These ports will classify all frames to
the Port VLAN identifier, independent of having VLAN
identifier or not;
C-Port: indicates that port will operate as C-port in the

ingress process. These ports will classify untagged frames
to the Port VLAN identifier and will forward tagged frames
to the VLAN embedded at the frame. At the egress
process, C-Ports forward tagged frames (if configured to)
with C-tag VLAN identifier;
S-Port: indicates that port will operate as S-port in the

ingress process. These ports will classify untagged frames
to the Port VLAN identifier. Tagged frames with Ethertype
0x8100 or 0x88A8 will be forwarded to the VLAN
embedded at the frame. At the egress process, S-Ports
forward tagged frames (if configured to) with S-tag VLAN
identifier;
 S-Custom-Port: indicates that port will operate as S-
custom-port in the ingress process. These ports will
classify untagged frames to the Port VLAN identifier.
Tagged frames with Ethertype 0x8100 or with the value
configured at the Ethertype for Custom S-ports will be
forwarded to the VLAN embedded at the frame. At the
egress process, S-Ports forward tagged frames (if
configured to) with S-tag VLAN identifier;
Ingress Filtering: enable frames ingress filtering function. If
o
enabled, frames classified to a VLAN that port is not member is
discarded. Thus, only Allowed VLANs identifiers and identifiers that
do not belong to the Forbidden VLANs frames will be accepted.
Checkbox selected means ingress filtering enabled, and checkbox
empty means disabled;
Ingress Acceptance: indicates ingress acceptance rules to be
o
applied if Ingress Filtering is enabled. Allowed values are Tagged
and Untagged, Tagged Only and Untagged Only, and possible
configuration are as follows:
Tagged and Untagged: means that port will accept both

tagged and untagged frames (respecting the Allowed
VLANs and Forbidden VLANs rules);
 Tagged Only: means that port will accept only tagged
frames (respecting the Allowed VLANs and Forbidden
VLANs rules). Untagged frames will be discarded;
 Untagged Only: means that port will accept only
untagged frames, which will be forwarded to the Port
VLAN identifier VLAN. Tagged frames will be discarded;
Egress Tagging: indicates egress tagging rules to be applied at
o
frame egress process at the port. Allowed values are Untag Port
