6. Specify the CST options:
• Bridge Priority. When switches or bridges are running STP, each is assigned a
priority. After exchanging BPDUs, the switch with the lowest priority value becomes
the root bridge. Specify the bridge priority value for the Common and Internal
Spanning Tree (CST). The valid range is 0–61440. The bridge priority is a multiple of
4096. If you specify a priority that is not a multiple of 4096, the priority is automatically
set to the next lowest priority that is a multiple of 4096. For example, if you set the
priority to any value between 0 and 4095, the switch automatically sets the value to 0.
The default is 32768.
• Bridge Max Age (secs). The bridge maximum age time for the Common and Internal
Spanning Tree (CST), which indicates the time in seconds a bridge must wait before
implementing a topological change. The valid range is 6–40, and the value must be
less than or equal to (2 * Bridge Forward Delay) – 1 and greater than or equal to 2 *
(Bridge Hello Time +1). The default is 20.
• Bridge Hello Time (secs). The bridge hello time for the Common and Internal
Spanning Tree (CST), which indicates the time in seconds a root bridge must wait
between configuration messages. The value is fixed at 2 seconds. The value must be
less than or equal to (Bridge Max Age / 2) – 1. The default hello time value is 2.
• Bridge Forward Delay (secs). The bridge forward delay time, which indicates the
time in seconds a bridge must remain in a listening and learning state before
forwarding packets. The value must be greater or equal to (Bridge Max Age / 2) + 1.
The time range is from 4 seconds to 30 seconds. The default is 15 seconds.
