616CHAPTER 38: MSTP CONFIGURATION COMMANDS

By default, No Agreement Check is disabled.

 

The No Agreement Check feature can take effect only on the root port or

n 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-standardcommand 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-standardcommand 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.
