Chapter 6. VLAN Management
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.
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.
Ingress Acceptance:
Hybrid ports allow for changing the type of frames that are accepted on ingress.
Tagged and untagged
both tagged and untagged frames are accepted.
Tagged Only
Only tagged frames are accepted on ingress. Untagged frames are discarded.
Untagged Only
Only untagged frames are accepted on ingress. Tagged frames are discarded.
Egress Tagging:
Ports in Trunk and Hybrid mode may control the tagging of frames on egress.
Untag Port VLAN
Frames classified to the Port VLAN are transmitted untagged. Other frames are
transmitted with the relevant tag.
Tag All
All frames, whether classified to the Port VLAN or not, are transmitted with a
tag.
Untag All
All frames, 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:
