Nt1210 Lab 5 Lab 5.1 Exercise 5.1.1 The 802.1 standards provide LAN/MAN management. The 802.1 standards where created by the close of the 1970’s. Exercise 5.1.2 802.3af is the standard that originally defined PoE functionality. The standard was enhanced in 2009 and was called 802.3at. Exercise 5.1.3 Standard Cabling Max length. 10Base5 Coaxial (Thicket) 500m 10Base2 Coaxial (Thinnet) 200m (practically 185m) 10Base-T UTP (cat3, 5, 5e, 6) 100m 100Base-FX MM 2km 100Base-T UTP (cat3, 5, 5e, 6) 100m 100Base-T4 UTP (cat5) 100m 100Base-TX UTP (cat5^) 100m 1000Base-LX MM 550m 1000Base-SX SM 220 m or 550 m (depending upon fiber thickness) 1000Base-ZX SM 100 km 1000Base-T UTP (4 pair) 100m Exercise 5.1.4 The numeric prefix before BASE tells you the speed it operates at. The letter combinations after BASE tells you the specifically what the standard is. The –T implies that it’s a UTP cable. Lab 5.1 review 1. The max speed of traffic from a node in network a using 10Base-T to a node in network B using 100Base-T would be 10Mbps. 2. It is possible for a network to uphold a maximum speed when using different UTP wires because the network knows what speed the standard allows it to work at. Lab 5.2 Exercise 5.2.1 The mac address must be unique for each NIC produced because the LAN uses it to figure out what NIC gets the packets its sending. If two devices from different manufactures share the last 24 bits of their mac address are on the same network the network won’t be able to tell what device gets the packets. This will cause confusion on the network and most likely cause errors. Exercise 5.2.2 The information that is given in the support tab of the status window is the address type, IP address, subnet mask, and default Gateway. Exercise 5.2.3 The MAC address of the NIC for this connection is
