n
The No Agreement Check feature can take effect only on the root port or
alternate port.
Examples # Enable No Agreement Check on Ethernet 1/1.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] stp no-agreement-check
stp pathcost-standard
Syntax stp pathcost-standard { dot1d-1998 | dot1t | legacy }
undo stp pathcost-standard
View System view
Parameters dot1d-1998: The device calculates the default path cost for ports based on IEEE
802.1D-1998.
dot1t: The device calculates the default path cost for ports based on IEEE 802.1t.
legacy: The device calculates the default path cost for ports based on a private
standard.
Description Use the
stp pathcost-standard command to specify a standard for the device to
use when calculating the default path cost of the link connected with the device
Use the
undo stp pathcost-standard command to restore the default setting
of the calculation standard.
The default standard used by the device is legacy.
Note that if you change the standard that the device uses in calculating the default
path cost, the port path cost value set through the stp cost command will be out
of effect.
