Ingress filtering
Each bridge port can be configured with the
check the
VID
of VLAN-tagged ingress traffic. This parameter decides whether a received frame is allowed or
dropped by the port:
If the parameter is disabled, both VLAN-tagged and non VLAN-tagged frames (i.e. untagged or priority-
tagged frames) are allowed on the port. Of course, these frames will only be sent out on interfaces that
are member of the correct VLAN.
If the parameter is enabled, VLAN-tagged frames are dropped if the receive port is not member of the
VID. VLAN-tagged frames are only allowed if the receive port is member of the VID. Non-VLAN tagged
frames are mapped to the VLAN that corresponds with the PVID.
By default, the parameter is disabled. To enable this parameter, execute following command:
=>:eth bridge ifconfig intf=ethport1 ingressfiltering=enabled
