4.5.3 Port Band Restrict

The function provides the In-Band and Out-Band connection speed restriction on the ports. The Band of the connection speed rangs from 64Kbps to 80000Kbps.

Ingress Port List/Egress Port List field can be filled in distinct number or a port range. For example, you can fill with “1, 3” for port 1 and port 3 and “3-5”for port 3 to port 5.

Band(64~80000Kbps) field can be filled with any number between 64 and 80000.

Due to the Chipset limition, set the band rate large then 500Kbps at In-Band Restrict field. NOTICE: If this value is less than 500Kbps and the packet will drop on that time.

And please also be remined, enable flow control at specific port is required.

4.6.1 Spanning Tree

1. Spanning Tree Protocol

The IEEE 802.1D Spanning Tree Protocol and IEEE 802.1W Rapid Spanning Tree Protocol allow for the blocking of links between switches that form loops within the network. When multiple links between switches are detected, a primary link is established. Duplicated links are blocked from use and become standby links. The protocol allows for the duplicate links to be used in the event of a failure of the primary link. Once the Spanning Tree Protocol is configured and enabled, primary links are established and duplicated links are blocked automatically. The reactivation of the blocked links (at the time of a primary link failure) is also accomplished automatically without operator intervention.

This automatic network reconfiguration provides maximum uptime to network users. However, the concepts of the
