Syntax
set port ingress-filter port-string{disable|enable}
Parameters
Defaults
None.
Mode
Switchcommand,Read‐Write.
Usage
Wheningressfilteringisenabledonaport,theVLANIDsofincomingframesarecomparedtothe
port’segresslist.IfthereceivedVLANIDdoesnotmatchaVLANIDontheport’segresslist,then
theframeisdropped.
IngressfilteringisimplementedaccordingtotheIEEE802.1Q
standard.
