Usage
The hello time is encoded in BPDUs in increments of 1/256ths of a second. The
Information
standard minimum hello time in seconds is 1 second, which is encoded as 256.
Millisecond hello times are encoded using values less than 256; the millisecond
hello time equals (x/1000)*256.
When you configure millisecond hellos, the default hello interval of 2 seconds is
still used for edge ports; the millisecond hello interval is not used.

Rapid Spanning Tree Protocol (RSTP)
— changes the time interval between BPDUs.
— changes the wait time before RSTP refreshes the protocol
Enter a number as the time interval between transmission of
BPDUs. The range is from 1 to 10 seconds. The default is 2
seconds.
Enter the keywords milli-second to configure a hello time
on the order of milliseconds. The range is from 50 to 950
milliseconds
