Feature Limitations

When STP or RSTP is enabled on a ring network, STP or RSTP immediately starts spanning tree calculation. Parameters such as the device priority and port priority affect spanning tree calculation, and the change of these parameters may cause network flapping. To ensure fast and stable spanning tree calculation, configure parameters such as the device priority and port priority before enabling STP or RSTP.

On a switch enabled with a spanning tree protocol, when a terminal connects to the switch, spanning tree calculation is performed again. As a result, it takes a long period of time for the terminal to obtain an IP address. In this case, disable the spanning tree protocol on the switch port connected to the terminal or configure this switch port as the edge port.
