After using the root protection of the port, if the port receives
the protocolinfo prior to root switch, it will transfer the port to
blocking state, no longer transmit message, & discard the
received protocol message to protect the status of the root
switch.
Loop protection function is a particular protection for loop net
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.
want to transform, it will inspire loop protection & set the port to
blocking state.
When configuring one port, you can configure only one of the
