switchport ingress-filtering
Use this command to enable ingress filtering for an interface. Use the
no
form to restore the default.
Syntax
switchport ingress-filtering
no switchport ingress-filtering
Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• 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 STP. 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)#
