SMC Networks 100BASE-TX, 16 10BASE-T manual Spanning-tree transmission-limit, Spanning-tree cost

4 Command Line Interface

Command Usage

The path cost method is used 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. Note that path cost (page 4-138)takes precedence over port priority (page 4-139).

Example

Console(config)#spanning-tree pathcost method long

Console(config)#

spanning-tree transmission-limit

This command configures the minimum interval between the transmission of consecutive RSTP BPDUs. Use the no form to restore the default.

Syntax

spanning-tree transmission-limit count no spanning-tree transmission-limit

count - The transmission limit in seconds. (Range: 1-10)

Default Setting

3

Command Mode

Global Configuration

Command Usage

This command limits the maximum transmission rate for BPDUs.

Example

Console(config)#spanning-tree transmission-limit 4

Console(config)#

spanning-tree cost

This command configures the spanning tree path cost for the specified interface. Use the no form to restore the default.

Syntax

spanning-tree cost cost no spanning-tree cost

cost - The path cost for the port. (Range: 1-200,000,000)) The recommended range is:

•Ethernet: 200,000-20,000,000

•Fast Ethernet: 20,000-2,000,000

•Gigabit Ethernet: 2,000-200,000
