SET MSTP PORT
Syntax
set mstp port=port|all [default]
[intportcost=auto|portcost]
[extportcost=portcost]
[portpriority=priority][edgeport=yes|no]
[pointtopoint=yes|no|autoupdate]
[migrationcheck=yes|no]
Parameters
port Specifies the port (that is, slot.port) you want to
configure. You can specify more than one port at a
time. To configure all ports in the switch, enter ALL.
(For information on how to enter ports, refer to
Specifying Ports on page 17.)
default Returns the port’s MSTP settings to their default
values.
intportcost Specifies the cost of a port connected to a bridge that
is part of the same MSTP region. This is referred to as
an internal port cost. The range is 0 to 200,000,000.
The default setting is Auto-detect (0), which sets port
cost depending on the speed of the port. Default
values are 2,000,000 for 10 Mbps ports, 200,000 for a
100 Mbps ports, and 20,000 for one gigabit ports.
extportcost Specifies the cost of a port connected to a bridge
which is a member of another MSTP region or is
running STP or RSTP. This is referred to as an external
port cost. The range is 0 to 200,000,000. The default
setting is 200,000.
portpriority Specifies the port’s priority. This parameter is used as a
tie breaker when two or more ports are determined to
have equal costs to the root bridge. The range is 0 to
240 in increments of 16. There are sixteen increments,
as shown in Table 10 on page 179. You specify the
increment of the desired value. The default is 128,
which is increment 8.
