          -- Behaviour Definitions


          -- ResettingTimer behaviour definition

          -- "This object specifies the interval between certain events in
          -- the operation of the protocol state machine. If the value of
          -- this object is set to a new value while the protocol state
          -- machine is in operation, the implementation shall take the
          -- necessary steps to ensure that for any time interval which
          -- was in progress when the value of the corresponding object
          -- was changed, the next expiration of that interval takes place
          -- the specified time after the original start of that interval,
          -- or immediately, whichever is later. The precision with which
          -- this time shall be implemented shall be the same as that
          -- associated with the basic operation of the timer object."


          -- ResourceLimiting behaviour definition

          -- "This object places limits on some "resource". In general,
          -- implementations may allocate resources up to this limit when
          -- the object is enabled and it may be impossible to change the
          -- allocation without first disabling and subsequently
          -- re-enabling the object (here disabling and enabling the
          -- object means that the operational state object associated
          -- with the resource limiting object is set to off and on
          -- respectively). It is only required that the value of the
          -- object be settable when the object is disabled. However, some
          -- implementations may be able to change the allocation of the
          -- resource while the object is enabled. In this case it is
          -- always permitted to increase the value of the object at any
          -- time, but it shall not be decreased below the currently
          -- "used" value of the resource."


          -- ExistenceState behaviour definition

          -- "This object controls the creation and deletion of the
          -- corresponding table row. Setting this object to the value off
          -- has the effect of invalidating the corresponding row. It is
          -- an implementation-specific matter whether the agent removes
          -- an invalidated row from a table. Accordingly, management
          -- stations must be prepared to receive tabular information from
          -- agents that corresponds to rows not currently valid. Setting
          -- the value of this object to the same value as its current
          -- value has no effect. If the table entry also contains an
          -- object controlling the operational state of a row (which
          -- follows the operationalState behaviour) then the object
          -- following the existenceState behaviour shall not be set to
          -- off when the object following the operationalState behaviour
          -- has value on. An attempt to do so is rejected."


          -- OperationalState behaviour definition

          -- "This object controls the enabling and disabling of the
          -- corresponding table row. Setting this object to the value
          -- off has the effect of disabling the corresponding row.
          -- Setting this object to the value on has the effect of
          -- enabling the corresponding row. Setting the value of this
          -- object to the same value as its current value has no effect.
          -- If the table entry also contains an object controlling the
          -- existence state of a row (which follows the existenceState
          -- behaviour) then the object following the operationalState
          -- behaviour shall not be set to on when the object following
          -- the existenceState behaviour has value off. An attempt to do
          -- so is rejected.


          -- ReplaceOnlyWhileDisabled behaviour definition

          -- "This object shall only be set when the corresponding row is
          -- disabled (has the value off for the corresponding operational
          -- state object)."


          -- ReplaceOnlyWhileInstanceDisabled behaviour definition

          -- "This object shall only be set when the corresponding row in
          -- the isisSysTable has isisSysOperState set to Off."


          -- Index behaviour definition

          -- "This object is an index object for the table entry. As such
          -- it can only be set to the value which is the same as that
          -- implicit in the Object Identifier value for the instance of
          -- this object."


          -- ManualOrAutomatic behaviour definition

          -- "The access of this object is read-write if the row to which
          -- it belongs is manual (i.e. is being or was created manually)
          -- otherwise (i.e. was created automatically) it is read-only."
