Port based VLANs
In this function, user can determine the output ports which this input port can send frames to.
For example, in above figure, only the ingress come from Port 4 and Port 8 can be send out from
Port 1.
802.1Q VLANs
If the 802.1Q VLAN Mode is enabled, you have to specify the VLAN groups to restrict the ingress
and egress.
Switch Management supports the different VID setting up to 64 in max. If the rules of the setting
have conflict, the smaller number of VID has the higher priority.
VID
Specify the VID number, the valid value is from 1 to 4095. Smaller number has the higher
priority.
Egress Policy
There are 4 options of egress tagging used to support 802.1Q VLAN.

Disable
: Ingress frames with this VID or the default VID are discarded.
Untagged
: port is a member of this VLAN and egress frames are untagged.
Tagged
