DHCP Basics

• Overview
• What is DHCP?
• Why use it?
• How does it work?

What is DHCP? DHCP allows a host to learn
its configuration parameters from a server. It
automates IP configuration, making it much easier
to connect to a network. It allows re-use of IP
addresses.

• Why use DHCP?
• Visitor convenience
• Speeds setup of new machines
• Simplifies conference room connections
• Allows roaming laptops
• Centralizes IP management

12
DHCP Basics

• How does DHCP work?1. Server discovery
• Client DHCPDISCOVER packet asking Who can
  give me DHCP information? Hello
• 2. Servers make an offer
• All servers on the subnet unicast a DHCPOFFER
  packet saying I can supply you with DHCP
  information, if you like. What Do You need
• 3. Client requests
• The client selects one of the responses, and
  broadcasts a DHCPREQUEST packet saying I choose
  server XYZ. Server XYZ, heres my MAC address,
  whats my IP address? Give Me An Address
• The unchosen servers treat this as a rejection.
• The request can specify a preferred IP address,
  if the client has a preference.
• The request can ask for additional information.
• 4. Server responds Here It is and for How
  long
• The server responds with a DHCPACK packet saying
  Here is your IP address. Its good for 24
  hours.
• The response can contain additional information,
  if the client asked for it.
• The server records that the IP address is in use.
• 5. Client releases You Can Have it Back
• The client finishes its work, and send a
  DHCPRELEASE packet saying Im done with the IP
  address.

13
DHCP Basics

• Clients refresh leases
• When half the lease time has expired, a client
  broadcasts another DHCPREQUEST packet saying I
  choose server XYZ. Server XYZ, I want IP address
  N. Can I have it?. The server responds yes or
  no.
• Servers can refuse
• If a server cant supply an unused IP address,
  or if the server cant supply an IP address that
  matches the clients MAC address, the server
  sends a DHCPNAK packet saying you cant have an
  IP address. The client is then free to make
  another request.
• Clients preserve addresses
• A client can remember its last-used IP address
  in non-volatile memory. When it boots, it can
  request the address from the server. This
  improves the chances that a client will retain
  the same IP address over long periods of time.

• What DHCP can provide
• IP address and lease time
• subnet mask
• default route
• DNS, NIS, LPR, NTP, logging server(s)
• WINS NBNS node type
• More
• Static vs. dynamic addresses
• DHCP servers manage two kinds of IP addresses
• o Static IP addresses, which the server
  gives to clients
• based on the clients MAC address
• o Dynamic IP addresses, which the
  server gives to
• clients as requested. These come
  from a pool of
• addresses in a subnet, set aside for
  this purpose

• The switch can be programmed with many Network
  names. All access points transmits these network
  names.
• Network Name (SSID) Closed Broadcast ( Cant See
  the Network Name under the Available Wireless
  Networks Window.
• Authentication
• WEP authentication encrypts data going across the
  airwaves so intruders can not snoop and
  reconstruct the packets intelligibly.
• WEP is either set to be shared or can run open
  mode.
• Open (Airespace) If user gets SSID right but
  WEP wrong a connection will be displayed but
  access will not be provided.
• Shared (Apple Basestation) User must have both
  correct to show a connection.
• 128 Bit Vs 40 bit.
• 128 Bit 13 Characters (ASCII) 26 Characters Hex
• 40 Bit 5 Characters (ASCII) 10 Characters Hex
• 802.1x Uses a Key loaded in each client device
  and in a special server (RADIUS) located at the
  site. Wireless Switch checks the network name
  and sends client information to RADIUS server to
  compare the key for authentication then checks
  the clients username and password for
  authenticity.
• Web Authentication Passwords are added to the
  switch. Users must load the appropriate network
  name, then open a browser to authenticate the
  password list on the switch.

Wireless Network Topology Kiosk
One or Two Cells of coverage in a small area such
as the media center will provide bandwidth
managed connectivity exactly where it is needed.
24
Wireless Network Topology Overlay
Overlapping Cells of coverage spread out
throughout the building to connect entire
buildings wirelessly. Services roaming clients.
Generally 10 to 15 devices per AP with low
bandwidth needs.
25
Wireless Network Topology One-To-One
Overlapping Cells of coverage installed in close
proximity and mounted throughout all rooms the
facility and servicing users with medium to high
bandwidth needs.
When the airespace switch detects high loads on
one access point it will transfer some clients to
other AP to share the load.

2 Floaters
2 floaters can be used in areas where there is no
infrastructure supported and heavy bandwidth
requirements are needed.
Ceiling Mount will share the work load with
floater on cart. When floater is pulled out of
the room ceiling mount still provides
connectivity to teachers staff and students

OSX 10.x IP Printing Configuration
Summary IP printing is the ability for a
printer to use TCP/IP protocols (such as LPD/LPR,
IPP, or Socket or Jet Direct) to make itself
accessible to your computer. If the printer you
want to use is not listed when you print, you can
add it to your list of available printers. To add
an printer using IP, you need to know its IP
address or DNS name. See your network
administrator for assistance.
Step 1. Open System Preferences on the Doc or
Blue Apple and click the Print Fax Icon.
Step 2. Click Printing tab, and then click the
Set Up Printers button.
Step 3. Click the Add Printer Icon in the printer
list.
Step 4. Choose IP Printing from the pop-up menu.
Step 5. Select Internet Printing protocol from
the Printer Type pop-up menu. Step 6. Type the
IP address for the printer in the Printer Address
field. If the printer IP address is not marked
ask your Tech Specialist. Step 7. Type in a
recognizable name into the Queue Name field.

Windows2000 WEP Wireless Client
Configuration Proxim ABG Card

• Summary Unlike WindowsXP, Windows2000 wireless
  client utilities are different from vendor to
  vendor and even within versions of a vendors
  client utility. To that end this instruction
  document will cover the ETS recommended Client
  Card (Dell True Mobile and Proxim ABG Client
  Card) and discuss differences in the Districts
  most popular client software.
• In most cases the Client card will come embedded
  on the laptop and pre configured for a Default
  setting.
• Configuration is all that will need changing. In
  cases where there is no client card pre
  installed, ETS recommends the Proxim ABG combo
  Card.
• In this case both the drivers and Client software
  will need to be installed.
• Important Never insert the card in the
  laptop until the software is loaded.
• If you do insert the card first and continue
  through the load procedures, you will need to
  uninstall the device driver from Windows 2000s
  Device Driver window located in the Control Panel
  by double clicking on the System Icon.
• Both the True Mobile and Proxim ABG Client Card
  configuration tool are similar in appearance and
  can be accessed by double clicking on the
  wireless icon in the systems tray or through
  Start-Programs-Dell True Mobile or Orinoco
