Ingress Filtering
Ingress filtering lets frames belonging to a specific VLAN to be forwarded if the port belongs to that VLAN. The switch has two ingress filtering rules, as follows:
Ingress Filtering Rule 1: Forward only packets with a VID matching this port's configured VID.
Ingress Filtering Rule 2: Drop untagged Frames.
4.4.8 Spanning Tree
The Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D) for avoiding loops in switched networks. When STP is enabled, it 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 interface Switch Setting Advanced item by selecting Enable Spanning Tree protocol. It is recommended that you enable STP on all switches to ensure a single active path on the network.
