• The 802.1w standard defines differently the default path cost for a port
compared to STP (802.1d). In order to avoid network topology change when
migrating to RSTP, the STP path cost is preserved when changing the spanning
tree version to RSTP. You can use the default RSTP port cost by using the CLI
command set port spantree cost auto.
