VLAN ID
Set the port VLAN ID that will be assigned to untagged traffic on a given port. This
feature is useful for accommodating devices that you want to include in the VLAN but
don’t support tagging. The switch allows users to set one VLAN ID for each port. The
range is 1~255; default VLAN ID is 1. The VLAN ID must be the same as the VLAN ID of
the VLAN group that the port belongs to or the untagged traffic will be dropped.
Ingress Filtering
Ingress filtering lets frames belonging to a specific VLAN to be forwarded to a port within
the same VLAN.
Enable: Forward only packets with VID matching this port's configured VID.
Disable: Disable Ingress filter function
Acceptable Frame type
ALL: Accept all Packets
Tag Only: Only packets with matching VLAN ID are permitted to go through the port.
5-4-8. Spanning Tree
The Spanning-Tree Protocol (STP) is a standardized method (IEEE 802.1D ) for
avoiding loops in switched networks. When STP is enabled, this method ensures that
only one path at a time is active between any two nodes on the network.
You can enable Spanning-Tree Protocol in the Web Management’s advanced page.
Select enable Spanning-Tree protocol. We recommend you enable STP on all switches
to ensure a single active path on the network.
