Ingress Filtering

Ingress filtering lets frames belonging to a specific VLAN be forwarded if

the port belongs to that VLAN. The SmartGST-801M has two ingress

filtering rules.

Ingress Filtering Rule 1: Forward only packets with VID matching this

port’s configured VID.

Ingress Filtering Rule 2: Drop Untagged Frames.

5-4-8. Spanning Tree

The Spanning-Tree Protocol (STP) is a standardized method (IEEE

802.1D) for avoiding loops in switched networks. Enabled STP ensures

that only one path at a time is active between any two nodes on the

network. You can enable Spanning-Tree Protocol on the Web

Management s advanced page. Select enable Spanning-Tree protocol.

Unicom recommends that you enable STP on all switches to ensure a

single active path on the network.
