Port Type - For normal ports this field will be blank. Otherwise the possible values are:
Mon - this port is a monitoring port. Look at the Port Monitoring screens for more information.
LAG - the port is a member of a Link Aggregation trunk. Look at the LAG screens for more
information.
STP Mode - The Spanning Tree Protocol Administrative Mode associated with the port or LAG. The
possible values are:
Enable - spanning tree is enabled for this port.
Disable - spanning tree is disabled for this port.
Forwarding State - The port's current state Spanning Tree state. This state controls what action a

the broken state. The other five states are defined in IEEE 802.1D:
Disabled
Blocking
