Parameters
time: Sets the forward delay in centiseconds, ranging from 400 to 3000 in steps of 100 (as in 400, 500,
600).
Description
Use stp timer forward-delay to set the forward delay timer of the device.
Use undo stp timer forward-delay to restore the default.
By default, the forward delay timer is 1500 centiseconds.
The forward delay timer determines the time interval of state transition. To prevent temporary loops, a
spanning tree port goes through the learning (intermediate) state before it transitions from the discarding
to the forwarding state. To stay synchronized with the remote device, the port has a wait period between
transition states that is determined by the forward delay timer.
HP does not recommend you to set the forward delay with this command. Instead, you can specify the
network diameter of the switched network by using the stp bridge-diameter command and let spanning
tree protocols automatically calculate optimal settings of the forward delay timer. If the network diameter
uses the default value, the forward delay timer also uses the default value.
Related commands: stp timer hello, stp timer max-age, and stp bridge-diameter.
Examples
# In MSTP mode, set the forward delay timer to 2000 centiseconds.
