set mstp msti port
Syntax SET MSTp MSTI=instance POrt={port-list|ALL}
[PRIOrity=0..255] [PAthcost=pathCost]
where:
■ instance is the instance number of the specified MSTI in a range from 1 to
4094.
■ port-list is a port number, range (specified as n-m), or comma-separated list
of port numbers and/or ranges. Port numbers start at 1 and end at m,
where m is the highest numbered Ethernet switch port, including uplink
ports.
■ pathcost is a value in the range 1 to 200,000,000.
Description This command sets tuning parameters for the specified ports or all ports for the
specified multiple spanning tree instance (MSTI). Modifying parameters for a
port will force a recalculation of the port roles for the specified msti.
The parameters assigned for the specified ports will only affect the network
topology of the specified msti, not any other spanning tree instances on the
switch.
The msti parameter specifies the instance number for the selected msti.
The port parameter specifies a list of ports to be configured for the specified
msti. If all is specified, all of the ports will be configured according to the new
parameter values for the specified msti.
The priority parameter sets the value of the priority field contained in the port
identifier. The MST algorithm uses the port priority when determining the root
port for the switch in the specified msti. The port with the lowest value is
considered to have the highest priority and will be chosen as root port over a
port - equivalent in all other aspects - but with a higher priority value. Any
value in the range 0 to 255 can be entered, but the switch will round the entered
value down to the nearest multiple of 16 (for example, if 17 is entered, 16 will
be used). The default value is 128. See Table 8-28 on page 8-156.
