•
Designated

The port's STP state. The state can be one of the following:
•
BLOCKING – STP has blocked Layer 2 traffic on this port to prevent a loop. The
device or VLAN can reach the root bridge using another port, whose state is
FORWARDING. When a port is in this state, the port does not transmit or
receive user frames, but the port does continue to receive STP BPDUs.
•
DISABLED – The port is not participating in STP. This can occur when the port
is disconnected or STP is disabled on the port.
•
FORWARDING – STP is allowing the port to send and receive frames.
•
LISTENING – STP is responding to a topology change and this port is listening
for a BPDU from neighboring bridges in order to determine the new topology.
No user frames are transmitted or received during this state.
•
LEARNING – The port has passed through the LISTENING state and will change
to the BLOCKING or FORWARDING state, depending on the results of STP's
reconvergence. The port does not transmit or receive user frames during this
state. However, the device can learn the MAC addresses of frames that the
port receives during this state and make corresponding entries in the MAC
table.
The best root path cost that this port received, including the best root path cost that
it can transmit.
The ID of the bridge that sent the best RST BPDU that was received on
this port.
