### Description

```asn1
ibmSEStpPortState OBJECT-TYPE 
SYNTAX INTEGER {forwarding(1), learning(2), listening(3), blocked(4), configured(5), netdown(6), configuring(7), unknown(8)} 
MAX-ACCESS read-only 
STATUS current 
DESCRIPTION 
"The port's current state as defined by 
application of the Spanning Tree Protocol. This 
state controls what action a port takes on 
reception of a frame. If the bridge has detected 
a port that is malfunctioning it will place that 
port into the broken(6) state. For ports which 
are disabled (see ibmSEPortEnable), this object 
will have a value of disabled(1). 
forwarding(1) - port is in forwarding state 
learning(2) - port is in learning state 
listening(3) - port is in listening state 
blocked(4) - this port is blocked by spanning tree 
configured(5) - this port is waiting for spanning tree 
netdown(6) - this ports network interface is down 
configuring(7) - this port is loading LEC configuration 
unknown(8) - this port is in some unknown state"
