Figure 7-20. Ingress Filtering Check window
Use this window to enable or disable the ingress filtering check for each desired port. Ingress filtering means that a
receiving port will check to see if it is a member of the VLAN ID in the packet before forwarding the packet. Click Apply
to let the settings take effect. Please note that this function only applies to IEEE 802.1Q VLANs mode.
