C-Port:
On ingress, frames with a VLAN tag with TPID = 0x8100 get classified to the
VLAN ID embedded in the tag. If a frame is untagged or priority tagged, the frame
gets classified to the Port VLAN. If frames must be tagged on egress, they will be
tagged with a C-tag.
S-Port:
On ingress, frames with a VLAN tag with TPID = 0x8100 or 0x88A8 get classified
to the VLAN ID embedded in the tag. If a frame is untagged or priority tagged, the
frame gets classified to the Port VLAN. If frames must be tagged on egress, they
will be tagged with an S-tag.
S-Custom-Port:
On ingress, frames with a VLAN tag with a TPID = 0x8100 or equal to the
Ethertype configured for Custom-S ports get classified to the VLAN ID embedded
in the tag. If a frame is untagged or priority tagged, the frame gets classified to the
Port VLAN. If frames must be tagged on egress, they will be tagged with the
custom S-tag.
5. Ingress Filtering :
Hybrid ports allow for changing ingress filtering. Access and Trunk ports always
have ingress filtering enabled.
If ingress filtering is enabled (checkbox is checked), frames classified to a VLAN
that the port is not a member of get discarded.
If ingress filtering is disabled, frames classified to a VLAN that the port is not a
member of are accepted and forwarded to the switch engine. However, the port
will never transmit frames classified to VLANs that it is not a member of.
6. VLAN Trunking :
Trunk and Hybrid ports allow for enabling VLAN trunking.
When VLAN trunking is enabled, frames classified to unknown VLANs are
accepted on the port whether ingress filtering is enabled or not.
This is useful in scenarios where a cloud of intermediary switches must bridge
VLANs that haven't been created. By configuring the ports that connect the cloud
of switches as trunking ports, they can seemlessly carry those VLANs from one
end to the other.
7. Ingress Acceptance :
Hybrid ports allow for changing the type of frames that are accepted on ingress.
