• Bridge Max Age (secs). Specifies the bridge maximum age time for the Common and
Internal Spanning Tree (CST), which indicates the amount of time in seconds a bridge
waits 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 value is 20.
• Bridge Hello Time (secs). Specifies the switch Hello time for the Common and Internal
Spanning Tree (CST), which indicates the amount of time in seconds a root bridge waits
between configuration messages. The value is fixed at 2 seconds.
• Bridge Forward Delay (secs). Specifies the switch forward delay time, which indicates
the amount of time in seconds a bridge remains 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 value is 15.
• Spanning Tree Maximum Hops. Specifies the maximum number of bridge hops the
information for a particular CST instance can travel before being discarded. The valid
range is 1–127.
