receive proposal packets from the upstream designated ports, instead of waiting for
agreement packets from the upstream switch. This enables designated ports of the
upstream switch to change their states rapidly.
Related commands: stp interface no-agreement-check.
 Note:
z The rapid transition function can be enabled on root ports or alternate ports only.
z If you configure the rapid transition function on the designated port, the function
does not take effect on the port.

Parameters
dot1d-1998: Uses the IEEE 802.1D-1998 standard to calculate the default path costs
of ports.
dot1t: Uses the IEEE 802.1t standard to calculate the default path costs of ports.
legacy: Uses the proprietary standard to calculate the default path costs of ports.
Description
Use the stp pathcost-standard command to set the standard to be used to calculate
the default path costs of the links connected to the switch.
Use the undo stp pathcost-standard command to specify to use the default standard.
