Console(config-if)#

16.236 switchport ingress-filtering

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

Syntax Description

[no] switchport ingress-filtering

Default

Disabled

Command Mode

Interface Configuration (Ethernet, Port Channel)

Usage Guidelines

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. They do affect

VLAN dependent BPDU frames, such as GMRP.

Example

This 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)#

16.237 switchport mode

This command configures the VLAN membership mode for a port. Use the no form to restore the default.

Syntax Description

switchport mode {trunk | hybrid}

no switchport mode

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 the port’s default VLAN (For

example, associated with the PVID) are also transmitted as tagged frames.
