S-Port: On Ingress Packets with a VLAN Tag with TPID = 0x8100 or 0x88A8 are set to the VLAN ID embedded in the
Tag. If a Frame is Untagged or Priority Tagged the Frame will be Tagged to the Port VLAN. If Packets are Tagged on
Egress they will be Tagged with a S-Tag.
X
S-Custom-Port: On Ingress Packets with a VLAN Tag with a TPID = 0x8100 or equal to the Ethertype configured for
Custom-S Ports are set to the VLAN ID embedded in the Tag. If a Frame is Untagged or Priority Tagged the Frame will
be Tagged to the Port VLAN. If Packets are Tagged on Egress they will be Tagged with a S-Tag.
Ingress Filtering
Hybrid Ports allow you to change Ingress Filtering. Access and Trunk Ports always have Ingress Filtering Enabled. If Ingress
Filtering is Enabled Packets Tagged to a VLAN the Port is not a Member of are Discarded. If Ingress Filtering is Disabled
Packets Tagged to a VLAN the Port is not a Member of are Accepted and Forwarded. However the Port will not Transmit
Packets Tagged to a VLAN it is not a Member of.
Ingress Acceptance
Hybrid Ports allow you to change the type of Packets that are Accepted on Ingress.
X
Tagged and Untagged: Both Tagged and Untagged Packets are Accepted.
X
Tagged Only: Only Tagged Packets are Accepted on Ingress. Untagged Packets are Discarded.
X
Untagged Only: Only Untagged Packets are Accepted on Ingress. Tagged Packets are Discarded.
Egress Tagging
Ports in Trunk and Hybrid Mode can control the Tagging of Packets on Egress.
X
UnTag Port VLAN: Packets classified within the Port VLAN are Transmitted Untagged. Other Packets are Transmitted
with the relevant Tag.
X
Tag All: All Packets whether classified to the Port VLAN or not are Transmitted with a Tag.
X
UnTag All: All Packets whether classified to the Port VLAN or not are Transmitted without a Tag (This option is only
available for Ports in Hybrid Mode).
Allowed VLANs
With Ports in Trunk and Hybrid Mode you can control which VLANs they are allowed to become Members of. Access
Ports can only be Member of one VLAN the Port VLAN. The fields syntax is identical to the syntax used in the Allowed
Access VLANs field. By default a Port may be a Member of all possible VLANs and is set to 1-4095. Allowed VLANs may
be left blank, the Port will not be Member of any of the Existing VLANs. However, if it is configured for VLAN Trunking it
will be able to carry all unknown VLANs.
Forbidden VLANs
A Port may be configured to never be allowed to become a Member of one or more VLANs. This is useful when dynam-
ic VLAN Protocols MVRP and/or GVRP must be prevented from dynamically Adding Ports into unintended VLANs. The
syntax is identical to the syntax used in the Allowed Access VLANs field. By default this field is left blank allowing the
Port may become a Member of all existing VLANs.
