NXA-ENET8POE Gigabit PoE Ethernet Switch

STA Introduction

The Spanning Tree Algorithm (STA) can be used to detect and disable network loops, and to provide backup

links between switches, bridges or routers. This allows the switch to interact with other bridging devices (that

is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between

any two stations on the network, and provide backup links which automatically take over when a primary link

goes down. The spanning tree algorithms supported by this switch include these versions:

STP - Spanning Tree Protocol (IEEE 802.1D)

RSTP - Rapid Spanning Tree Protocol (IEEE 802.1w)

RSTP - Settings page (Cont.)

Port: The port ID. It can not be changed. Aggregations means any configured trunk

group.

Enabled:

Click on the box to enable/disable the RSTP protocol for the port.

Edge:

Expect the port to be an edge port (linking to an end station) or a link to

another STP device.

Path Cost (0...200000000, 0

means autogenerated path

cost)

This parameter is used by the STP to determine the best path between

devices. Therefore, lower values should be assigned to ports attached to

faster media, and higher values assigned to ports with slower media. Set the

RSTP pathcost on the port. Number between 0 - 200000000. 0 means auto-

generated pathcost.
