CMIT 265 Lab exercise "Bold edit" in your answers. Name:_______________________________ Looking at LAN workstation and connectivity hardware: Port, NIC, cable, switch Using the PCs in the lab or our classroom network. On the PC: Network interface adapter (NIA or NIC (card)) is a built-in port of the motherboard. (all PCs now have a built-in Ethernet port. Expansion card maybe for extra port, maybe at faster speed.) Built-in port or expansion bus card?: _______ Port LEDs: Number of them, what labeling, color(s), behavior: _______ _________________________________________________________________ _________________________________________________________________ _________________________________________________________________ (laptops save a nickel by not having any LEDs on the NIC port. If your laptop lacks them, go to lab to see the exciting blinking lights.) Patch cable label (what is printed on the cable): _________________________________________________________ This cable is UTP (unshielded twisted pair). It consists of 8 copper wires, in 4 pairs; each pair is twisted together to reduce interference (viz. crosstalk) with the other pairs. The pairing is for reducing external interference. What does the other end of the patch cable plug into (make and model, #ports): _________________________________________________________________ Which port on that switch is your PC's patch cable plugged into:_______ What are its LED(s) doing:___________________________________ Any labels of the rows on that connectivity device, colors of the LEDs and their behavior: ________________________________________________________ ________________________________________________________ ________________________________________________________ ________________________________________________________ Windows: Hovering on the network icon in the system tray says what: ______________ ______________ ______________ left-click networking icon in System tray / Taskbar Connections says what:______________________ right-click networking icon in System tray, choose "Open Network and Sharing Center" 8/10 calls it "Connections" and "Ethernet" (which is the correct term). Ethernet Status: 7/8/10: Media State:_____________ Duration: _______ Speed: _______ Ethernet runs at 10, 100, or 1000 Mbps (million bits per seconds) #bytes sent: ____________ (since last reboot or Enable of NIC?) #bytes received: ____________ (All data/information/messages/bits travel in bundles called packets (or frames).) Details: 7/8/10: DHCP Enabled:_______ using DHCP the computer will get its networking configuration automatically from the network. IPv4 address: ____________ each computer in the network will have a different IP address. Collaborating with your neighbors, what is the common part of your IP addresses:__________ Subnet mask: ____________ used with IP address to determine network address. Default gateway: ____________ IP address of the router in this network that this computer sends packets that need to go to other networks. DNS server(s): _____________________________ IP address of computer that provides a DNS name to IP address translation service. Physical address: _______________________ also known as MAC address. Used for intra-LAN communication: each frame that leaves your computer is going to a computer in the same network and is addressed by its MAC address. DHCP server: ______________________ IP address of the computer that gave this computer its networking configuration. Lease obtained: _____________________ Lease expires: _____________________ the DHCP networking configuration is valid only for a certain amount of time. Description:________________________________________________ the hardware/chip device that does the Ethernet networking. (Note: to find duplex setting: Admin Tools | Event Viewer | System event messages) Ethernet Status | Properties Properties of Internet Protocol Version 4: IP Address Obtained Automatically?:____ (yes means uses DHCP, i.e. dynamically vs. statically) DNS server address obtained automatically?:_____ Ethernet Status | Properties Configure (or Device Manager|Network Adapters ) Manufacturer:______________ Location:_____________ Device status:______________________________ Driver|DriverDetails file(s): _______ Advanced|Speed & Duplex setting:__________ Other choices:________Duplex, speeds All this information is rarely needed. CMD Command Prompt: Start | Run | cmd or hold WindowsKey and r then cmd type: ipconfig /all Ethernet adapter Ethernet: Notice this is the same information as the Ethernet Status window. Unplug the RJ45 from its jack at the network port on PC by squeezing its snappy tab/clip and pulling. Any visible (eg. window alert, tray icon) or audible reaction: _____________________________________________ _______ LED(s) on the switch are what:_______________ Look closely at the RJ-45 connector, its pins and the wire strands. Cable wires layout (i.e. order of colors of the wires 1-8, left to right on bottom opposite of tab): _________________________________________________________________ _________________________________________________________________ _________________________________________________________________ Connect cable back into port, watching the LEDs. What LED goes on first:____________ (the connectivity LED). Then what LED:________________ (activity LED flickers?)
