Chapter 3 - Configuring the REX2
4Set 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)
aTo set the maximum age, type 3 then press ENTER . 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
bTo set the hello time, type 4 then press ENTER . At the prompt, enter a time interval in seconds at which the
Enter New Hello Time : 4
cTo set the forward delay, type 5 then press ENTER . 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.
5To set the LAN port priority, type 6 then press ENTER . 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.
