NT1210 Lab 5.1 LAN Standards
Exercise 5.1.1
The IEEE standards cover more than just Ethernet. The 802.3 standard actually builds upon the 802.1 network architecture standard from IEEE. Briefly define the 802.1 standard and what it provides. Use your textbook and the Internet to research your answer.
IEEE 802.1 Working Group (IEEE 802.1) is an IEEE Standards Association (IEEE-SA) group established to ensure network management and monitoring capabilities in networks developed according to IEEE 802 standards.
Exercise 5.1.2
The 802.3 family of standards has the format 802.3x where x is a sequence of letters specifying the new standards added to the 802.3 base standard. One of the enhancements to Ethernet is Power over Ethernet (PoE), in which Ethernet cable can provide power to remote, low-power devices that are not near an electrical outlet. What 802.3 standard originally defined PoE functionality? When was the standard enhanced, and what was the new standard name given for the enhancement? Use your textbook and the Internet to research your answer.
802.3 standard originally came about in June 2003 then designated IEEE 802.3at was released in 2009 and this provided for several enhancements to the original IEEE 802.3af specification. Some devices include powering IP telephones, wireless LAN access points, webcams, Ethernet hubs and switches.
Exercise 5.1.3
Complete Table 5-1 by researching the various Ethernet standards and their associated properties. You can use your textbook and the Internet to determine the answers.
