Parameters
time: Sets the forward delay in centiseconds, in the range of 400 to 3000 in increments of 100 (as in
400, 500, 600).
Usage guidelines
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
state 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 recommends not setting 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 the spanning tree
protocols automatically calculate the optimal settings for the forward delay timer. If the network diameter
uses the default value, the forward delay timer also uses the default value.
Examples
# In MSTP mode, set the forward delay timer to 2000 centiseconds.
