blocking state, no longer transmit message, & discard the
received protocol message to protect the status of the root
switch.

topology. In the network that exists ring, redundant topology
will be in the state of backup, & in the state of blocking after the
port is steady. If there is no need to transfer to transmission
state, it is possible to set port to loop protect. Once the port

blocking state.
When configuring one port, you can configure only one of the
three protection:BPDU protection, root protection & loop
protection.
