Ingress
Filtering
Ingress filtering instructs the VLAN engine to filter out undesired traffic on a port.
• When you Enable Ingress Filtering, the port checks whether the incoming frames
belong to the VLAN they claimed or not. The port then determines if the frames can
be processed or not. For example, if a tagged frame from TEST VLAN is received,
and Ingress Filtering is enabled, the ES8508 determines if the port is on the TEST
VLAN’s Egress list. If it is, the frame can be processed. If it is not, the frame is
dropped.
• When you select Disable, the port accepts all incoming frames regardless of its VLAN
classification. This control does not affect VLAN independent BPDU frames, such as
Super Ring, STP, GVRP and LACP. It does affect VLAN dependent BPDU frames,
such as GMRP.
