Syntax
[no] switchport ingress-filtering
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.
switchport mode {access | hybrid | trunk}
no switchport mode
access - Specifies an access VLAN interface. The port transmits and receives
untagged frames on a single VLAN only.
hybrid - Specifies a hybrid VLAN interface. The port may transmit tagged or
untagged frames.
