undo spf-slice-size
View
IS-IS view
Parameters
duration-time
: Specifies the duration in milliseconds of each sliced SPF calculation,
ranging from 10 to 50000. Each sliced SPF calculation is ended when the duration time
is reached. If the
duration-time
is set to 0, the entire SPF calculation will not be sliced.
Description
Use the
spf-slice-size
command to specify the duration for each sliced SPF
calculation.
Use the
undo spf-slice-size
command to restore the default.
By default, the duration of each sliced SPF calculation is 10 milliseconds.
To prevent the SPF calculation from occupying the system resources for a long time,
you can use this command to slice the whole SPF calculation into pieces.
You are not recommended to change the default setting.
Examples
# Set the duration of each sliced SPF calculation to 1 second.
