Command mode:

Default:
The forward delay time is 15 seconds by default.
Usage Guide:
When the network topology changes, the status of the port is changed from blocking to forwarding. This delay is called
the forward delay. The forward delay is co working with hello time and max age. The parameters should meet the
following conditions. Otherwise, the MSTP may work incorrectly.
2 * (Bridge_Forward_Delay - 1.0 seconds) >= Bridge_Max_Age
Bridge_Max_Age >= 2 * (Bridge_Hello_Time + 1.0 seconds)
Example:
In global mode, set MSTP forward delay time to 20 seconds.
