Optional 
By default, MSTP is enabled on all ports. 
To enable a switch to operate more flexibly, you can 
disable MSTP on specific ports. As MSTP-disabled 
ports do not participate in spanning tree calculation, 
this operation saves CPU resources of the switch.

Other MSTP-related settings can take effect only after MSTP is enabled on the switch. 
Configuration example 
# Enable MSTP on the switch and disable MSTP on Ethernet 1/0/1. 
1)  Perform this configuration in system view 
<Sysname> system-view 
[Sysname] stp enable 
[Sysname] stp interface Ethernet 1/0/1 disable 
2)  Perform this configuration in Ethernet port view 
<Sysname> system-view 
[Sysname] stp enable 
[Sysname] interface Ethernet 1/0/1 
[Sysname-Ethernet1/0/1] stp disable
