Configuring the network diameter of a switched network
Any two terminal devices in a switched network can reach each other through a specific path, and there are a series of devices on the path. The switched network diameter is the maximum number of devices on the path for an edge device to reach another one in the switched network through the root bridge. The network diameter indicates the network size. The bigger the diameter, the larger the network size.
Based on the network diameter you configured, the system automatically sets an optimal hello time, forward delay, and max age for the device.
In STP, RSTP, or MSTP mode, each MST region is considered a device. The configured network diameter takes effect only on the CIST (or the common root bridge) but not on other MSTIs.
In PVST mode, the configured network diameter takes effect only on the root bridges of the specified VLANs.

Step | Command | Remarks |
