Chapter 5 Ethernet LANs
Lab 5.1: LAN Standards
Exercise 5.1.1
IEEE 802.1 handles the architecture, security, management and internetworking of local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN) standardized by IEEE 802.
Exercise 5.1.2
Power over Ethernet is defined by a standard set forth by the IEEE 802.3af task force.
Exercise 5.1.3 Standard Cabling Maximum Length 10BASE5 Coaxial (Thicknet) 500 m 10BASE2 Coaxial (Thinnet) 200 m 10BASE-T UTP (Cat3, 5,5e,6) 100-150 m 100BASE-FX MM fiber optic 400 m 100BASE-T UTP or optical fiber 100 m 100BASE-T4 UTP (Cat3 or above) 100 m 100BASE-TX UTP (Cat5 or above cable) 100 m 1000BASE-LX MM fiber optic 550 m 1000BASE-SX MM fiber optic 220 m or 550 m (dependent upon fiber thickness) 1000BASE-ZX Single-mode fiber optic 100 km 1000BASE-T UTP (CAT5) 100 m
Exercise 5.1.4
The numeric prefix before BASE in the Ethernet standards defines the transmission speed.
Lab 5.2: MAC and IP Addresses
Exercise 5.2.1
A MAC address must be unique for every NIC produced because switches forward frames based on their destination MAC address and if more than one NIC in the same LAN were to have the same MAC address (including the last 24 bits in the MAC address) then the switches would be confused as to which NIC would get the frame.
Exercise 5.2.2
Address type, IP Address, subnet mask and default gateway.
Exercise 5.2.3
