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
Ports in Trunk and Hybrid mode may control which VLANs they are allowed to become
members of. Access ports can only be member of one VLAN, the Access VLAN.
