what difference is between "set spantree portpri " and "et spantree portvl"

[cobra_he]

can you tell me where to use these two command separately?

I suppose you mean portpri and portvlanpri.

Portpri changes the port priority for all VLANs existing on that port while portvlanpri allows you to change the port priority on a VLAN basis.

Thanks.
