Syntax

[no] switchport ingress-filtering

Default Setting

Disabled

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.
