Relationship with Other Parameters
None.
7.71 Max Age(s)
Description
The
Max Age(s)
parameter specifies the maximum life cycle of the configuration message. A
configuration message contains the message aging time and maximum aging time of the
message. The maximum life cycle of the configuration message is equivalent to the maximum
aging time of the message.
Impact on the System
If the message aging time exceeds the maximum aging time of the message, the received message
is discarded and the port that receives the message becomes a designated port.

Configuration Guidelines
When you set the value of this parameter, ensure that the following requirement is met:
2 x (Hello Time + 1)
≤
Max Age
≤
2 x (Forward Delay - 1)
Relationship with Other Parameters
This parameter is related to the
Hello Time
and
Forward Delay
parameters. For details, refer
to the principles for setting these parameters.
7.72 Hello Time(s) (Spanning Tree)
Description
The
Hello Time(s)
parameter specifies the transmission period of the message.
The bridge time consists of the following parts: forward delay of the bridge, handshake time of
the bridge, maximum bridge aging time, and message aging time (0). The
Hello Time
parameter
is equivalent to the bridge handshake time.
Impact on the System
This parameter ensures the stable operation of the STP.
