• 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.
