This command enables ingress filtering for an interface. Use the no form to

Interface Configuration (Ethernet, Port Channel)

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.

The following example shows how to set the interface to port 1 and then

enable ingress filtering:

Console(config)#interface ethernet 1/1

Console(config-if)#switchport ingress-filtering

Console(config-if)#

This command configures the VLAN membership mode for a port. Use the

no form to restore the default.

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.

trunk - Specifies a port as an end-point for a VLAN trunk. A trunk is

a direct link between two switches, so the port transmits tagged

frames that identify the source VLAN. Note that frames belonging to
