stp msti port priority This command displays or sets the CIST/MSTI priority for specified
interfaces.
SYNTAX
stp msti port priority [msti] [port-list] [priority]
msti - STP bridge instance number. (Range: 0-7, where 0 is the
CIST, and 1-7 are MST instances)
port-list - A specific port or a range of ports. (Range: 1-28, all for
all ports, or 0 for all link aggregation groups)
priority - The priority for an interface. (Range: 0-240, in steps of
Range: 0-240 in steps of 16; Options: 0, 16, 32, 48, 64, 80, 96,
112, 128, 144, 160, 176, 192, 208, 224, 240)

COMMAND USAGE
This command defines the priority for the use of a port in the Spanning
Tree Algorithm. If the path cost for all ports on a switch are the same, the
port with the highest priority (i.e., lowest value) will be configured as an
active link in the Spanning Tree. This makes a port with higher priority less
likely to be blocked if the Spanning Tree Algorithm is detecting network
loops. Where more than one port is assigned the highest priority, the port
with lowest numeric identifier will be enabled.
