Restore the disabled Root protection state, as defaulted, (from
Ethernet port view)

Restore the disabled loop protection state, as defaulted (from
Ethernet port view)
After configured with BPDU protection, the switch will disable the edge port through
RSTP, which receives a BPDU, and notify the network manager at same time. Only the
network manager can resume these ports.
The port configured with Root protection only plays a role of a designated port.
Whenever such port receives a higher-priority BPDU when it is about to turn into
non-designated port, it will be set to a listening state and not forward packets any more
(as if the link to the port is disconnected). If the port has not received any higher-priority
BPDU for a certain period of time thereafter, it will resume to the normal state.
When configure a port, only one configuration can be effective among loop protection,
Root protection and Edge port configuration at same moment.
By default, the switch does not enable loop protection, BPDU protection or Root
protection.
For detailed information about the configuration commands, refer to the Command
Manual.
