Introduction

By forwarding only packets addressed to devices on other network segments, the SmartSTACK 10 ELS10-26 reduces unnecessary traffic and thereby enhances the overall performance of the network.

Note: If the packet address is not found in the Bridge Address Table, it will be forwarded (flooded) to all network segments.

Spanning Tree Algorithm

The SmartSTACK 10 ELS10-26 supports the IEEE 802.1d Spanning Tree algorithm. The Spanning Tree algorithm converts multiple LANs into a “spanning tree” of networks. It is used to prevent bridging loops. This standard defines a logical (not physical) network configuration consisting of one extended LAN without active duplicate paths between spanning tree bridges.

The SmartSTACK 10 ELS10-26, along with other IEEE 802.1d Spanning Tree compliant bridges in the network, dynamically configure the network topology into a single Spanning Tree by exchanging Bridge Protocol Data Units (BPDUs). Typically, each LAN segment is sent one BPDU every two seconds (this is the default setting).

When there are multiple SmartSTACK 10 ELS10-26s connecting LANs in a loop, the Spanning Tree algorithm determines which SmartSTACK 10 ELS10-26 should forward packets to the LAN. If there is a cable break or a port failure, the network topology is automatically reconfigured by the Spanning Tree protocol to create an alternate path to the LAN.

1.5.2 SmartSTACK 10 ELS10-26 Bridge Address Table

The SmartSTACK 10 ELS10-26 creates and maintains a dynamic database of addresses called the Bridge Address Table. The SmartSTACK 10 ELS10-26 examines every packet to determine its source address and LAN segment origin. It then compares the source address and segment information it finds to the entries in the Bridge Address Table.
