spanning-tree msti
Congures 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 inuences 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
Supported Releases 10.2.0E or later
