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.
Page 90: Stp Timer Max-Age
HP recommends not setting the hello time 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 hello timer.

The max age timer is ineffective for MSTIs. HP recommends not setting the max age timer 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 max age timer.
Page 92: Stp Transmit-Limit
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.
