4.4.7.4.3 Configure Ingress Filter
The following screen page appears when you choose Tag VLAN Settings and then select
Ingress Filter from the pull-down menu of Select Setting.
The default setting for all ports is “Enable”.
Ingress Filter Enable: When enabled, ingress traffic from a port that belongs to one of the
existing VID entries is allowed to pass through; otherwise, they will be dropped before
checking the entire VID table.
Ingress Filter Disable: When disabled, incoming frame VID will not be compared with the
ingress port VLAN membership. It will only check its address table to see whether the
destination VLAN exists.
For example:
VLAN Table Settings:
