7.4.2 Preparation for configuration
Networking situation
In big LAN, multiple devices are concatenated for inter-access among hosts. They need to
enable STP to avoid loop among the devices, MAC address learning fault, and broadcast
storm and network down caused by quick copy and transmission of data frame. STP
calculation can block one interface in a broken loop and make sure that there is only one path
from data flow to destination host, which is also the best path.
Preconditions
Configure interface physical parameters to make it Up before configuring STP.
