3.3.4.2Configuring Advanced STA Settings

This section describes advanced settings for RSTP.

When configuring RSTP settings through the web interface or CLI, the following parameters can be configured:

Path Cost Method – The setting that defines the range of values that can be assigned as the path cost of each interface. The path cost is used to determine the best path between devices in the spanning tree.

Long: Specifies 32-bit based values that range from 1 to 200,000,000.

Short: Specifies 16-bit based values that range from 1 to 65,535.

Transmission Limit – An RSTP parameter (between 1 and 10) that defines the rate at which each bridge in the spanning tree transmits BPDUs to its neighbours to inform them that the configured ports are still linked. The maximum transmission rate for BPDUs is specified by setting the minimum interval between the transmission of consecutive protocol messages. The default is 3.

Web Interface: Configuring Advanced STA Settings

1.Open Switch Config Spanning Tree Advanced Configuration.

2.Modify the required parameters.

3.Click Save.
