In the BPDU Protection area, select disable to disable BPDU guard globally.
or select enable to enable BPDU guard globally.
BPDU guard can protect the device from malicious BPDU attacks, making the
network topology stableT. here are five options in the Protection area.
Configure & Enable & Disable BPDU guard on a port:

No Change: keep default or current configuration.
Not Set: No protection is enabled on the port.
Edge Port:set the port as an edge port.
Some ports of access layer devices are directly connected to PCs or file servers, which cannot
generate BPDUs. You can set these ports as edge ports to achieve fast transition for these ports.
HP recommends you to enable the BPDU guard function in conjunction with the
edged port function to avoid network topology changes when the edge ports
receive configuration BPDUs.
Root Protection:Enable the root guard function.
Configuration errors or attacks may result in configuration BPDUs with their
priorities higher than that of a root bridge, which causes a new root bridge to be selected and
network topology change to occur. The root guard function is used to address such a problem.
Loop Protection:Enable the loop guard function.
By keeping receiving BPDUs from the upstream device, a device can maintain the
state of the root port and other blocked ports.
These BPDUs may get lost because of network congestion or unidirectional link failures.
In this case, the device will re-elect a root port, and blocked ports may transit to the
forwarding state, causing loops in the network.
The loop guard function is used to address such a problem.
