## Configure Ingress Filtering

Enabling ingress filtering on a port does not allow frames for a VLAN from a port that is not the member port of that particular VLAN. The default is disabled. The following procedure includes port 0/2 as the example port.

1. Enable ingress filtering on the port.

       SEFOS# configure terminal
       SEFOS(config)# interface extreme-ethernet 0/2
       SEFOS(config-if)# switchport ingress filter
       SEFOS(config-if)# end

2. Review the configuration details.

       SEFOS# show vlan port config port extreme-ethernet 0/2
