set spantree default-path-cost
Command Mode Global Configuration.
Description Sets the type of default path costs that ports in a specific bridge will use.
Options are:
■
common-spanning-tree—uses the 16-bit default path costs from
IEEE Std. 802.1D-1998:
— For 10 MB ports, 100
— For 100 MB ports, 19
— For 1 GB ports, 4
— For 10 GB ports, 3
■
rapid-spanning-tree—uses the 32-bit default path costs from IEEE
Std. 802.1t:
— 10 Mbps port—2,000,000
— 100 Mbps port—200,000
— 1 Gbps port—20,000
— 10 Gbps port—2,500
* Note: The switch must be running Rapid Spanning Tree to use the
Rapid Spanning Tree default path costs. If the switch is running
common Spanning Tree, it uses the common Spanning Tree
default path costs regardless of default path cost setting.
Syntax set spantree default-path-cost {common-spanning-tree | rapid-spanning-
tree} {802.1D | vlan {<vlan-id> | name <vlan-name>}}
