Set the maximum age, the hello time, and the forward delay using the
following procedures. These values are related. If you choose incorrect
values, an error message displays
a
To set the maximum age, type
enter a value in seconds. This value indicates the maximum age for
Spanning Tree information in the bridging table before it is
discarded. The valid range is 6 to 40 seconds (default value is 20
seconds):
b
To set the hello time, type
enter a time interval in seconds at which the Campus-REX2 should
send Spanning Tree Protocol packets (BPDUs). The valid range is 1
to 10 seconds (the default value is 2 seconds):
c
To set the forward delay, type
enter a time interval in seconds that should be waited until the state
of an interface can change. The valid range is 2 to 30 seconds (the
default value is 15 seconds):
This delay prevents interface states from changing so rapidly that
Spanning Tree Protocol cannot keep up with the current network
topology and therefore cannot efficiently manage bridging.
5
To set the LAN port priority, type
enter a value for the LAN port priority between 0 and 255 (the default
value is128):
Enter New LAN Port Priority : 50
Port priorities are set relative to other ports on the same bridge. The Line
is the other port on this bridge.

Value entered is not within constraints
2 * (Forward Delay - 1) >= Max Age > 2 * (Hello
Time + 1)
Enter New Max Age : 30
Enter New Hello Time : 4
Enter New Forward Delay : 30
