SET RSTP PORT
Syntax
set rstp port= port [pathcost|portcost= cost |auto]
[portpriority= portpriority ]
[edgeport=yes|no|on|off|true|false]
[ptp|pointtopoint=yes|no|on|off|true|false|autoupdate]
[migrationcheck=yes|no|on|off|true|false]
[loopguard=enabled|disabled]
Parameters
port Specifies the port you want to configure. You can
specify more than one port at a time. For instructions,
refer to “Port Numbers in Commands” on page 48.
pathcost or Specifies the port’s cost. The parameters are
portcost equivalent. The spanning tree algorithm uses the cost
parameter to decide which port provides the lowest cost
path to the root bridge for that LAN. The options are:
cost A number for the port cost. The range is
1to 200,000,000.
auto Automatically sets the port cost according
to the speed of the port. This is the default.
Table 17 lists the port cost with auto-
detect.
Table 18 lists the RSTP port costs with
Auto-Detect when the port is part of a port
trunk.
