B) The default spanning tree port cost standard for H3C switches is legacy
C) H3C switches support three port cost standards, dot1d-1998, dot11, and legacy. The port cost standards to be followed can be switched through the command stp pathcost-standard
D) If switches of different manufacturers are interconnected, each switch should be configured to follow the same port cost standard as much as possible, otherwise it may cause the spanning tree calculation result to deviate from the original intention of the network design
