Command Mode
Interface Configuration (Ethernet, Port Channel)
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.
