Hello Nahro

The difference you see here in commands has to do with the version of STP that is running. [Rapid STP](https://networklessons.com/spanning-tree/rapid-spanning-tree-configuration) uses the `edgeport` keyword. What STP version is active will depend upon the platform and IOS being used, and the default STP version being used on that particular platform/IOS version.

Here is the command reference for the `spanning-tree portfast edge bpdufilter default` command:

And here is the command reference for the `spanning-tree portfast bpdufilter default` command:

Take a look at this thread for some more info on these commands that you see in your output:

> Hello Rene, I received one of the virl switch images and was building a lab testing spanning tree. Can you tell me what is the difference between the commands listed below: #spanning-tree portfast edge #spanning-tree portfast network #spanning-tree normal and when should you use which one? Also i read the lessons on both spanning-tree uplinkfast and spanning-tree backbonefast. Both commands seem to do the same thing , fast convergence if a link or indirect link fails. Maybe i am not und…

I hope this has been helpful!
