tnPortPhysStateChangeCount

The value of tnPortPhysStateChangeCount indicates the number of times
a physical port state has changed from 'linkDown (3)' to either
'linkUp (4)' or 'up (5)' and from either 'linkUp (4)' or 'up (5)' to
'linkDown (3)'.  The count does not include transitions between
'linkUp (4)' and 'up (5)'.
              
This counter is applicable to physical Ethernet ports only. All other
ports maintain a count of 0.
              
This object is automatically reset to zero, once the port enters the
'ghost (2)' state.  To reset this object manually, one may use the
tnClearTable entry whose tnClearName value is
'clearPortPhysStateChangeCount' by specifying the tnClearParams value
with 'port-id=<ifIndex>'.
