switchport ingress-filtering

This command enables ingress filtering for an interface.

Although the ingress filtering command is available, the switch has ingress filtering
permanently set to enable. Therefore, trying to disable the filtering with the
no switchport ingress-filtering command will produce this error message:
"Note: Failed to ingress-filtering on ethernet interface !"

Command Usage
• Ingress filtering only affects tagged frames.
• With ingress filtering enabled, a port will discard received frames tagged for
VLANs for it which it is not a member.
• 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.
