Hello,
Topology:
![Topology.png Topology.png](/t5/image/serverpage/image-id/49391i182E19381373BBD4/image-size/large?v=v2&px=999)
"CISCO-3750-.253"Already set to vlan3 Root.Then why vlan3 root is"CISCO-3750G"?
What is the answer to the situation if the topology is unchanged?
"CISCO-3750G" show spanning(vlan 3 mac address identical but priority different )

PS.I have tried changing the upper right to trunk mode,back to normal.But this is not the answer I want.
Thanks.Best regards !!
