Command Usage
• Ingress filtering only affects tagged frames.
• If ingress filtering is disabled and a port receives frames tagged for
VLANs for which it is not a member, these frames will be flooded to all
other ports (except for those VLANs explicitly forbidden on this port).
• If ingress filtering is enabled and a port receives frames tagged for
VLANs for which it is not a member, these frames will be discarded.
• 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.
