spanning-tree msti

Configures the MSTI, cost, and priority values for an interface.

Syntax
spanning-tree msti instance {cost cost | priority value}
Parameters
  • msti instance — Enter the MST instance number (0 to 63).
  • cost cost — (Optional) Enter a port cost value (1 to 200000000). Default values:
    • 100 Mb/s Ethernet interface = 200000
    • 1-Gigabit Ethernet interface = 20000
    • 10-Gigabit Ethernet interface = 2000
    • Port-channel interface with one 100 Mb/s Ethernet = 200000
    • Port-channel interface with one 1 Gigabit Ethernet = 20000
    • Port-channel interface with one 10 Gigabit Ethernet = 2000
    • Port-channel with two 1 Gigabit Ethernet = 18000
    • Port-channel with two 10 Gigabit Ethernet = 1800
    • Port-channel with two 100 Mbps Ethernet = 180000
  • priority value — Enter a value in increments of 16 as the priority (0 to 240, default 128) .
Default
Priority value is 128
Command Mode
INTERFACE
Usage Information
The cost is a value based on the interface type. The greater the cost value, the less likely the port is selected to be a forwarding port. The priority influences the likelihood that a port is selected to be a forwarding port if several ports have the same cost.
Example
OS10(conf-if-eth1/1/1)# spanning-tree msti 1 priority 0
                                       OS10(conf-if-eth1/1/1)# spanning-tree msti 1 cost 3
