Command Usage
•If ingress filtering is enabled, incoming frames for VLANs which do not include this ingress port in their member set will be discarded at the ingress port.
•Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP or STA. However, they do affect VLAN dependent BPDU frames, such as GMRP.
Example
The following example shows how to set the interface to port 1 and then enable ingress filtering:
Console(config)#interface ethernet 1/1
