Regarding the Views Expressed

• Per IEEE-SA Standards Board Operations Manual, J 2005January 2005:“At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE t d d h ll k it l th t hi h istandards shall make it clear that his or her views

should be considered the personal views of that individual rather than the formal position, explanation, or interpretation of the IEEE ”or interpretation of the IEEE.

• The views I am expressing on IEEE standards and related products should NOT be considered the formal position explanation or interpretation of the Ethernetposition, explanation, or interpretation of the Ethernet Alliance.
