Dell PowerConnect 8024 - Spanning-Tree Mst Cost; Spanning-Tree Mst Port-Priority

Spanning Tree Commands 477
spanning-tree mst cost
Use the spanning-tree mst cost command in Interface Configuration mode to configure the
path cost for multiple spanning tree (MST) calculations. If a loop occurs, the spanning tree
considers path cost when selecting an interface to put in the forwarding state. To return to the
default port path cost, use the no form of this command.
Syntax
spanning-tree mst instance-id cost cost
no spanning-tree mst instance-id cost
• instance-ID — ID of the spanning -tree instance. (Range: 1-15)
•
cost — The port path cost. (Range: 0–200,000,000)
Default Configuration
The default value is 0, which signifies that the cost will be automatically calculated based on
port speed.
The default configuration is:
• Ethernet (10 Mbps) — 2,000,000
• Fast Ethernet (100 Mbps)
— 200,000
• Gigabit Ethernet (1000 Mbps)

• Port-Channel
— 20,000

Interface Configuration (Ethernet, Port-Channel) mode
User Guidelines
This command has no user guidelines.
Example
The following example configures the MSTP instance 1 path cost for interface 1/g9 to 4.
console(config)#interface ethernet 1/g9
console(config-if-1/g9)#spanning-tree mst 1 cost 4
spanning-tree mst port-priority
Use the spanning-tree mst port-priority command in Interface Configuration mode to
configure port priority. To return to the default port priority, use the no form of this command.
