stp delay <delay_time>
<delay_time>
• Maximum forward delay time
Specify a maximum forward delay time within the range of 4 to 30 seconds.
The unit will be s (second).
Configuration mode (admin class)
Set a maximum forwarding delay time.
This setting is disabled when this device does not function as a root bridge even if it uses
an STP.
Specify the time period required to change from the listening state to the learning state or
from the leaning state to the forwarding state via an STP.
<delay_time> checks the relationship with the definition value of stp age <max_age>.
• Check with max age time
max age time <= 2 × (forward delay time - 1.0 second)
If the definition value is invalid, the set values of <max_age>, <delay_time>, and <time>
will be disabled.
The following shows definition conditions that are available for checking the relationship
between <max age>, <delay_time>, and <time>.
2 × (forward delay time - 1.0 second) >= max age time >= 2 × (hello time + 1.0 second)
It is assumed that 15 seconds are set for a maximum forwarding delay time.
