column r/w Enumeration 
The link class controls the behavior of a link when a failure
is detected on the link or on the node connected to the
remote end of the link. The link class decides which values
the dtmLinkStateNodeStatus object can take.  
              
A link is monitored with the following mechanisms:
              
- The underlying trunk interface will detect when the signal
  on the receiving interface disappears or is impossible to
  use due to errors. This is called a Signal Failure.
              
- The communication with the node at the remote end of the
  link is monitored by periodically sending messages, and
  expecting responses. If no response is received within a
  reasonable time, a failure is assumed. This is called a
  Supervision Failure.
              
The error detection mechanisms can detect failures in one or
both directions of a bi-directional link. If a failure is
detected in only one direction of a bi-directional link and
there is another fully working link in the opposite
direction, the remaining working links will all have status
`up'.
              
The link classes are:
              
normal(1)
If either a Signal Failure or Supervision Failure is detected
on the link, the link is considered as `down' and its entry
is removed from the dtmLinkStateTable.
              
persistent(2)
If a Signal Failure is detected on the link, the link is
considered as `down' and its entry is removed from the
dtmLinkStateTable. If a Supervision Failure is detected on
the link, the object dtmLinkStateIfNodeStatus for the link is
assigned `noControl'.
              
nailed(3)
If a Signal Failure is detected on the link, the object
dtmLinkStateIfNodeStatus for the link is assigned `downKeep'.
If a Supervision Failure is detected on the link, the object
dtmLinkStateIfNodeStatus for the link is assigned
`noControl'.
