Interface Configuration (Ethernet, Port Channel)
Command Usage
• If ingress filtering is enabled, incoming frames for VLANs which do
not include this ingress port in their member set will be discarded at the
ingress port.
• 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.
Example
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)#
