Syntax
switchport ingress-filtering
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.
