stp timer-factor

Use stp timer-factor to configure the timeout interval by setting the timeout factor.
Timeout interval = timeout factor × 3 × hello time.
Use undo stp timer-factor to restore the default.
Syntax
stp timer-factor factor
undo stp timer-factor
Default
The timeout factor of a device is set to 3.

Parameters
factor: Sets the timeout factor in the range of 1 to 20.
Usage guidelines
After the network topology is stabilized, each non-root-bridge device forwards configuration BPDUs to
the surrounding devices at the interval of hello time to determine whether any link is faulty. If a device
does not receive a BPDU from the upstream device within nine times of the hello time, it assumes that the
upstream device has failed and will start a new spanning tree calculation process.
In a stable network, this kind of spanning tree calculation might occur because the upstream device is
busy. You can avoid such unwanted spanning tree calculations by lengthening the timeout interval (by
setting the timeout factor to 4 or more), thus saving network resources. HP recommends that you set the
timeout factor to 5, 6, or 7 for a stable network.
Examples
# Set the timeout factor of the device to 7.
