LAB 2 - PACKET TRACER BUILD SHEET: ROOM 204       cyberteaches.com/networking/lab-2
Tested layout for Cisco Packet Tracer 8.x. Device models are suggestions; any
router with a GigabitEthernet port and any 2960 switch will work.
--------------------------------------------------------------------------------
SIMPLIFICATION: The real Room 204 gateway has two LAN ports. In the simulator,
connect SWITCH-B to SWITCH-A instead. Everything else matches the inventory.

1. PLACE DEVICES
   - 1 router (ISR4321 or 1941), named ROUTER-204
   - 2 switches (2960-24TT), named SWITCH-A and SWITCH-B
   - 1 AccessPoint-PT, named WAP-204
   - 4 PCs: ST-01 and ST-02 on SWITCH-A, ST-13 and ST-14 on SWITCH-B
   - 1 Server-PT named FILESERVER-204, 1 Printer-PT named PRINTER-204
   - 1 Laptop-PT named TEACHER-LT (power off, replace its Ethernet module with
     the WPC300N wireless module, power on)

2. CABLE (Copper Straight-Through)
   ROUTER-204 Gig0/0/0 (or Gig0/0) -> SWITCH-A Gig0/1
   SWITCH-A Gig0/2                 -> SWITCH-B Gig0/1
   SWITCH-A Fa0/1, Fa0/2           -> ST-01, ST-02
   SWITCH-A Fa0/15                 -> FILESERVER-204
   SWITCH-A Fa0/20                 -> WAP-204 Port 0
   SWITCH-B Fa0/1, Fa0/2           -> ST-13, ST-14
   SWITCH-B Fa0/8                  -> PRINTER-204

3. CONFIGURE THE ROUTER (CLI tab)
   Router> enable
   Router# configure terminal
   Router(config)# hostname ROUTER-204
   ROUTER-204(config)# interface gigabitEthernet 0/0/0      (use g0/0 on a 1941)
   ROUTER-204(config-if)# ip address 10.204.0.1 255.255.255.0
   ROUTER-204(config-if)# no shutdown
   ROUTER-204(config-if)# exit
   ROUTER-204(config)# ip dhcp excluded-address 10.204.0.1 10.204.0.99
   ROUTER-204(config)# ip dhcp excluded-address 10.204.0.200 10.204.0.254
   ROUTER-204(config)# ip dhcp pool ROOM204
   ROUTER-204(dhcp-config)# network 10.204.0.0 255.255.255.0
   ROUTER-204(dhcp-config)# default-router 10.204.0.1
   ROUTER-204(dhcp-config)# dns-server 8.8.8.8
   ROUTER-204(dhcp-config)# end
   ROUTER-204# copy running-config startup-config
   (The two excluded ranges leave .100-.199 for DHCP, matching the inventory.)

4. STATIC ADDRESSES (Desktop > IP Configuration > Static)
   FILESERVER-204: 10.204.0.10   mask 255.255.255.0   gateway 10.204.0.1
   PRINTER-204:    10.204.0.20   mask 255.255.255.0   gateway 10.204.0.1

5. DHCP CLIENTS (Desktop > IP Configuration > DHCP)
   ST-01, ST-02, ST-13, ST-14. Each should receive an address from .100-.199.

6. SECURE THE WIRELESS NETWORK (WAP-204 > Config > Port 1)
   SSID: choose a unique name (not "Room204" or a default name)
   Authentication: WPA2-PSK, Encryption: AES
   Pass phrase: a long, unique pass phrase (12+ characters, all four sets)
   Then on TEACHER-LT: Desktop > PC Wireless > Connect, choose your SSID,
   enter the pass phrase, and set IP Configuration to DHCP.

7. VERIFY
   On ST-13: Desktop > Command Prompt
     ipconfig             (address in .100-.199, gateway 10.204.0.1)
     ping 10.204.0.1      (gateway)
     ping 10.204.0.10     (file server)
   On TEACHER-LT: ipconfig, then ping 10.204.0.10
   On ROUTER-204: show ip dhcp binding   (lists the leased addresses)

8. RECREATE A TICKET
   Pick one: delete the ST-14 cable (ticket 2043), turn off ST-02's interface
   (Config > FastEthernet0 > Port Status: uncheck On, like ticket 2044), or set
   ST-01 to DHCP before ROUTER-204 is configured (like ticket 2042). Record the
   symptom, the evidence (ipconfig, ping, link lights), the fix, and the
   verification.
