4 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
Value entered is not within constraints
:
2 * (Forward Delay - 1) >= Max Age > 2 * (Hello
Time + 1)
a To set the maximum age, type then press . At the prompt,
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):
Enter New Max Age : 30
b To set the hello time, type then press . At the prompt,
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):
Enter New Hello Time : 4
c To set the forward delay, type then press . At the prompt,
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):
Enter New Forward Delay : 30
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 then press . At the prompt,
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.
