Root cost
The root cost of a switch is the sum of root port cost and the
root cost that data packet goes through all switches. The root
cost of root bridge is zero.
Basic
information
The display bar of basic information table
Port
It displays the port number of this device.
Priority
The priority of ports in network bridge. The values range from
0 to 240. The smaller the value, the higher the port priority.
The higher the priority, the more likely it is to be a root port.
Cost
The path cost from network bridge to root bridge.
P2P
The directly connected switch port.
Edge
The port that directly connects to terminal instead of other
switches.
Connected
It displays the network protocol of devices with connected
ports.
Role
Root port, specified port, Alternate port and Backup port.
FWD status
It is divided by whether the port forwards user flow and learns
MAC address.
Discarding: neither forward user flow nor learn MAC
address;
Learning: doesn’t forward user flow but learn MAC
address;
Forwarding: forward user flow and learn MAC address;
Listening: neither forward user flow nor learn MAC
address; but can receive and send configuration
message;
Blocking: port only receives and processes BPDU,
doesn’t forward user flow;
Disabled: blocked or physically disconnected.
The settings of rapid spanning tree will take effect after rebooting the device.
