[Problem Description]

[Cause] 

The version of CE8860EI V200R002C50SPC800 v-stp value is written 2000 and cannot be modified in vxlan toponogly.

We will confirm if all of version is this value from R&D.

[Solution ]

V-STP cost is written 2000 cannot be modified in all CE6870-48S6CQ-EI version.

That's all for this case.

If you have any further questions, kindly let us know.

Thanks.
