RSTP, defined by 802.1w standard, is an alternative to #202207081637, would speed the process, that put a port into a forwarding state, up (by default, it took around at least 30 seconds to set up) by allowing ports (alternative and backup port) to be immediately put into forwarding state, which is especially helpful in critical system. However, this allows the possibility of 202207081644#.

Spanning Tree Protocol (STP)
When a port first become active, it will not be put immediately into forwarding state to avoid causing the network loop. According to 802.1d, it will go through 3 states sequentially: listening (the switch transmits and receives BPDUs to determine the state of the spanning tree), learning (continue listening, plus receives traffic and begins building a bridge table based on the source MAC addresses of the traffic), and forwarding. The first two stages take 15 seconds each by default, which is 30 seconds in total. To speed it up, try 202207122007# instead.
