DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide Example This example shows how to configure the STP timers. Switch# configure terminal Switch(config)# spanning-tree hello-time 1 Switch(config)# spanning-tree forward-time 16 Switch(config)# spanning-tree max-age 21 Switch(config)# 78-14 spanning-tree state This command is used to enable or disable the STP operation. Use the no form of this command to revert to the default setting. spanning-tree state {enable | disable} no spanning-tree state Parameters enable disable Specifies to enable STP for the configured interface. Specifies to disable STP for the configured interface. Default By default, this option is enabled. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline When a port is spanning tree enabled, the spanning tree protocol engine will either send or process the spanning tree BPDU received by the port. The command should be used with caution to prevent bridging loops. The command does not take effect if the Layer 2 protocol tunnel is enabled for STP. Example This example shows how to enable Spanning Tree on ethernet 1/0/1. Switch# configure terminal Switch(config)# interface ethernet 1/0/1 Switch(config-if)# spanning-tree state enable Switch(config-if)# 78-15 spanning-tree cost This command is used to configure the value of the port path-cost on the specified port. Use the no form of this command to the auto-computed path cost. 803
