If this command is configured on a member port in an aggregation group, is takes effect only after the
port leaves the aggregation group.
If you do not specify an MSTI or VLAN, this command sets the path cost of a port in the MSTP CIST
or in the STP or RSTP spanning tree.
Examples
# In MSTP mode, set the path cost to 200 for GigabitEthernet 1/0/1 in MSTI 2.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] stp instance 2 cost 200
# In PVST mode, set the path cost to 200 for GigabitEthernet 1/0/1 in VLAN 2.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] stp vlan 2 cost 200

Usage guidelines
Dispute guard blocks a port to prevent loops when an unidirectional link is detected on the port by the
spanning tree feature.
In some VLAN networks, an uplink port on a downstream device is configured to deny packets from
the PVID. As a result, the downstream device cannot receive BPDUs of the PVID from the upstream
device. However, the upstream device can receive BPDUs from the downstream device. In this case,
dispute guard blocks the receiving port on the upstream device, which causes traffic interruption.
To ensure service continuity and prevent the link from being blocked, you can disable dispute guard
by using the
undo stp dispute-protection command.
Examples
# Disable dispute guard.
<Sysname> system-view
[Sysname] undo stp dispute-protection
