These items are generic in the sense that they are required for managed Systems in general. The follow

23、ing items are defined to aid in the completeness of this International Standard, although it is recognized that they are outside the bounds of the definition area for a layer 2 Standard. E.2 Scope This annex defines additional attributes and an action that are necessary to the management of a comple

24、te intermediate System such as a repeater. They are not specifically related to a Data Link Layer Management Standard. When a g ener #ic Systems manag ement Standard is available with these definitions expected that this Portion of this International Standard will be removed. (or similar), it is E.3

This may have been caused by

26、 ResetSystemAction or other means. This counter has a value of 0 when initialized. Though the count is reported in tens of milliseconds, the required resolution is to the nearest 100 ms. The clocking Source for the counter shall be accurate to within 1 % througout the full counting range.; NOTE: The
