Spanning-Tree Commands spanning-tree mst cost The spanning-tree mst cost Interface Configuration mode command configures 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 configuration, use the no form of this command. Syntax spanning-tree mst instance-id cost cost no spanning-tree mst instance-id cost Parameters n instance-ID - ID of the spanning-tree instance (Range: 1-16). n cost - The port path cost. (Range: 1-200,000,000) Default Setting Default path cost is determined by port speed and path cost method (long or short) as shown in the following table: Interface Port-channel Gigabit Ethernet (1000 Mbps) Fast Ethernet (100 Mbps) Ethernet (10 Mbps) Long 20,000 20,000 200,000 2,000,000 Short 4 4 19 100 Command Modes Interface Configuration (Ethernet, port-channel) mode Command Usage There are no user guidelines for this command. Example The following command configures the MSTP instance 1 path cost for Ethernet port e42 to 4. console(config) # interface ethernet e42 console(config-if) # spanning-tree mst 1 cost 4 22-18 www.hp.com HP PC Blade Switch CLI Reference Guide
