4.6.1 RSTP System Configuration
The “RSTP System Configuration” table allows configuring the spanning tree parameters.
Figure
The page includes the following fields:
•System Priority Specifies the bridge priority value. 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. The bridge priority value is provided in increments of 4096 (4K increments). For example, 0, 4096, 8192, etc.
| The default value is 32768. |
• Hello Time | Specifies the device Hello Time. The Hello Time indicates the amount of time in |
| seconds a root bridge waits between configuration messages. |
| Value Range: |
| The default is 2 seconds. |
• Max Age | Specifies the device Maximum Age Time. The Maximum Age Time indicates the |
| amount of time in seconds a bridge waits before sending configuration messages. |
| Value Range: |
| The default max age is 20 seconds. |
•Forward Delay Specifies the device forward delay time. The Forward Delay Time indicates the amount of time in seconds a bridge remains in a listening and learning state before forwarding packets.
| Value Range : |
| The default is 15 seconds. |
• Force version | Specifies the Force Protocol Version parameter for the switch. The options are |
| Normal and Compatible |
| Normal – Rapid STP (802.1w): Detects and uses of network topologies that |
| provide faster spanning tree convergence, without creating forwarding loops. |
| Compatible – Classis STP (802.1d): Provides a single path between end |
