Introduction
Task 2: Configure the PCs and switch VLANs and perform Test 1
Step 1: Connect devices and configure PC IP addresses
Connect the switch to the router as shown in the Test Plan topology diagram.
Connect the PC1 and PC2 hosts to the switch using the ports indicated in the Test Plan topology table.
Using the IP address information from the Test Plan table, configure PC1 and PC2.
Step 2: Prepare the switch for configuration
Connect a PC with a console cable to the switch to perform configurations using a terminal emulation
program. Confirm that the switch is ready for lab configuration by ensuring that all existing VLAN and general configurations are removed. Remove the switch startup configuration file from NVRAM.
Switch#erase startup-config
Erasing the nvram filesystem will remove all files! Continue? [confirm]
Press Enter to confirm. The response should be:
Erase of nvram: complete
If the switch has previously been configured with VLANs, it will necessary to delete the VLAN
database information file. From the privileged EXEC mode, issue the following commands:
Switch#delete vlan.dat
Delete filename [vlan.dat]?[Enter]
Delete flash:/vlan.dat? [confirm] [Enter]
If there was no VLAN file, this message is displayed.
%Error deleting flash:/vlan.dat (No such file or directory)
It is recommended that the delete command not be issued as: delete flash:vlan.dat.
Accidentally omitting vlan.dat from this command could lead to the complete IOS being deleted
from flash memory. Issuing the reload command to restart the switch may not always clear the previous VLAN configuration; for that reason, the power cycle (hardware restart) step is recommended.
Step 3: Configure VLANs on switch S1
Configure switch S1 with a hostname and passwords.
Switch(config)#hostname FC-ASW-1
FC-ASW-1(config)#enable password cisco
FC-ASW-1(config)#enable secret class
FC-ASW-1(config)#line console 0
FC-ASW-1(config-line)#password cisco
FC-ASW-1(config-line)#login
FC-ASW-1(config-line)#line vty 0 15
FC-ASW-1(config-line)#password cisco
FC-ASW-1(config-line)#login
FC-ASW-1(config-line)#exit
FC-ASW-1(config)#
Configure switch S1 with the VLAN 1 IP address of 10.0.1.2/24.
FC-ASW-1(config)#interface vlan1
FC-ASW-1(config-if)#ip address 10.0.1.2 255.255.255.0
FC-ASW-1(config-if)#no shutdown
FC-ASW-1(config-if)#exit
FC-ASW-1(config)#
Configure switch S1 with the default gateway address of 10.0.1.1.
FC-ASW-1(config)#ip default-gateway 10.0.1.1
FC-ASW-1(config)#
Create VLAN 10 named main-net and VLAN 20 named voice.
FC-ASW-1(config)#vlan 10
FC-ASW-1(config-vlan)#name main-net
FC-ASW-1(config-vlan)#exit
FC-ASW-1(config-vlan)#vlan 20
FC-ASW-1(config-vlan)#name voice
FC-ASW-1(config-vlan)#exit
FC-ASW-1(config)#
Assign interface range Fa0/2 through Fa0/12 to VLAN 10.
FC-ASW-1(config)#interface range fa0/2 – 12
FC-ASW-1(config-if-range)#switchport mode access
FC-ASW-1(config-if-range)#switchport access vlan 10
FC-ASW-1(config-if-range)#exit
FC-ASW-1(config)#
Assign interface range Fa0/13 through Fa0/24 to VLAN 20.
FC-ASW-1(config)#interface range fa0/13 – 24
FC-ASW-1(config-if-range)#switchport mode access
FC-ASW-1(config-if-range)#switchport access vlan 20
FC-ASW-1(config-if-range)#end
FC-ASW-1#
Step 4: Perform Test 1 to determine if the hosts can communicate between VLANs
a. Issue the show running-config commands from the switch and verify all basic configuration
settings. See output at end of lab.
b. Issue the show vlan brief command on the switch to verify what ports are in which VLANs.
Which switch ports are in VLAN 1?
Fa0/1 Gi0/1, Gi0/2
Which switch ports are in VLAN 10?
Fa0/2 – Fa0/12
Which switch ports are in VLAN 20?
Fa0/13 – Fa0/24
FC-ASW-1#show vlan brief
VLAN Name Status Ports
1 default active Fa0/1, Gi0/1, Gi0/2
10 main-net active Fa0/2, Fa0/3, Fa0/4, Fa0/5

<*** output omitted ***>
c. With PC1 connected to switch port 4 and PC2 attached to port 14, attempt to ping from PC1 to PC2.
Would you expect the ping to be successful?
Tidak
Why or why not?
PC IP addresses are on different networks (PC1 is on net 10.0.10.0/24 and PC2 is on net 10.0.20.0/24 and in different VLANs.
d. Change the IP address of PC2 to 10.0.10.5 so that the two PCs are on the same network and ping again. Would you expect the ping to be successful?
Tidak
Why or why not?
Alamat IP PC punya alamat jaringan yang sama tapi masih di VLAN yang berbeda
e. Move the cable for PC2 to a port that is in the VLAN 10 range (Fa0/2 to Fa0/12) and ping again.
Would you expect the ping to be successful?
Ya
Why or why not?
Alamat IP PC berada pada jaringan dan VLAN yang sama
f. Change the IP address for PC2 back to 10.0.20.2 and move the cable back to Fa0/14 in VLAN 20.
This test demonstrated that the PCs from the main-net cannot communicate with the PCs on the voice net without assistance from a Layer 3 device.
Task 3: Configure the switch and router for VLAN routing and perform Test 2
Step 1: Configure VLAN trunking on switch S1
Configure trunking between switch S1 and the router with 802.1 encapsulation on both devices.

FC-CPE-1(config-subif)#exit
FC-CPE-1(config)#interface fa0/0.10
FC-CPE-1(config-subif)#encapsulation dot1Q 10
FC-CPE-1(config-subif)#ip address 10.0.10.1 255.255.255.0
FC-CPE-1(config-subif)#exit
FC-CPE-1(config)#interface fa0/0.20
FC-CPE-1(config-subif)#encapsulation dot1Q 20
FC-CPE-1(config-subif)#ip address 10.0.20.1 255.255.255.0

Step 4: Perform Test 2 to determine if the hosts can communicate between VLANs through the use of inter-vlan routing provide by a router
a. Issue the show running-config commands from the switch and verify all basic configuration
settings. See output at end of lab.
b. Ping from the switch to the router default gateway for VLAN 1.
Was the ping successful?
Ya
c. Telnet from the switch to the router.
Where you successful?
Ya
d. With PC1 connected to switch port 4 and PC2 attached to port 14, attempt to ping from PC1 to PC2.
Would you expect the ping to be successful?
Ya
Why or why not?
PC IP addresses are on different networks (PC1 is on net 10.0.10.0/24 and PC2 is on net 10.0.20.0/24 and in different VLANs but the router is routing packet between the two independent subnets.
e. Telnet from PC1 to the switch and the router.
Would you expect the Telnet to be successful?
Ya
Why or why not?
Physical and IP connectivity has been previously verified. As long as there are no VTY restrictions or ACLs in place, each PC should be able to telnet to either the switch using the VLAN1 IP address or to the router using any of the router subinterface addresses.
f. Issue the show ip route command on the router to display the routing table. How many subnet
routes are there?

Step 4: Reflection
Was the prototype testing of the FilmCompany LAN design successful? Did having a test plan to work from help you organize your testing?
Lab 7.2.6 Analyzing Results of Prototype Tests
Step 1: Identify if weaknesses are present in the design
Is the design able to scale to meet the growth, or do budget constraints limit the types of hardware and
infrastructure that can be included?
Secara umum, desain bersifat scalable. Prototipe menggunakan beberapa switch dan link yang berulang.
Do the IP addressing and VLAN configurations allow for the proposed growth?
Pengalamatan IP menggunakan skema swasta memanfaatkan ruang alamat 192.168.0.0/22 yang menyediakan ruang cukup untuk pertumbuhan. Ke-11 VLAN pasti semua memungkinkan untuk alamat tambahan yang akan ditambahkan. Melakukan pengujian dengan dua PC dan dua VLAN cukup untuk mencapai tujuan pengujian. Jika bekerja dengan dua PC dan dua VLAN itu akan bekerja dengan PC lebih banyak dan lebih VLAN, kecuali kesalahan konfigurasi diperkenalkan.
Can the selected hardware be upgraded easily without a major reconfiguration of the network?
Secara umum, ya. Stackable tetap 2960 konfigurasi switch digunakan dalam prototipe. IOS software dapat ditingkatkan dengan cukup mudah tapi upgrade perangkat keras mungkin tidak menjadi pilihan. Perluasan kepadatan pelabuhan dan penggunaan kecepatan link berbeda dan media yang dapat menyajikan isu-isu.
Can new Access Layer modules be integrated into the network without disrupting services to existing users?
Ya. Switch tambahan dapat ditambahkan untuk meningkatkan jumlah koneksi di desain dengan gangguan minimal.
Does the design provide for the smallest possible failure domains?
Ya, switch menyediakan segmentasi mikro dan VLAN berisi broadcast dengan menggunakan router dan subinterfaces.
Are there multiple paths and redundant devices to protect against losing connectivity to important services?
Ya. Switch memiliki hubungan yang berulang untuk memberikan cadangan.
Step 2: Determine what the risks are of not correcting the weaknesses
If, in Step 1, you identify weaknesses in the proposed design, what risks do these weaknesses present to
FilmCompany?
Sejak stackable switch dengan konfigurasi tetap digunakan dalam prototipe, perubahan kepadatan port, jenis media atau kecepatan link dapat menimbulkan masalah. Selain menambahkan lebih banyak switch, perluasan kepadatan port tidak mudah dilakukan.
Step 3: Suggest ways that the design can be improved to reduce the risk
In what ways could the proposed design be improved to reduce the areas of risk?
Step 4: Document the weaknesses and risks on the test plan
In the Results and Conclusions section of the test plan, record any weaknesses, risks, and suggested
improvements.
Step 5: Reflection
Why do you think it is important to identify weaknesses and risks in the proposed design before presenting it to the customer? What are some reasons that weaknesses cannot be corrected?
Penting untuk mengidentifikasi kelemahan dan risiko dalam desain yang diusulkan sebelum menyajikannya kepada pelanggan untuk memastikan bahwa pelanggan memahami keterbatasan prototipe dan tidak mengarah pada memiliki harapan yang tidak realistis berdasarkan prototipe. Mungkin mustahil untuk mengimbangi semua kelemahan yang dapat diidentifikasi karena masalah waktu, uang atau kendala personil. Risiko harus dianalisa dan seimbang terhadap variabel-variabel lainnya.

Re-issue the show span command.
How long did it take the switches to determine and utilize a backup link?
Step 4: Induce a device failure on the network
Turn off the ProductionSW switch.
Ping from H1 to H2.
Was the ping successful?
Yes, both hosts are on the FC-ASW-1 switch and inter-VLAN
routing is still taking place.
Step 5: Reflect on the test results
In a network with multiple branch offices, why is the use of Rapid Spanning Tree Protocol important?
RSTP adalah penting untuk memastikan konektivitas perangkat pada layer akses di setiap kantor cabang dan bahwa sumber daya seperti server yang dapat diakses oleh pengguna di kantor-kantor lain yang bergantung pada mereka, dalam hal terjadi kegagalan switch-terkait setempat.
Why is it important when implementing a server farm?
RSTP akan membantu untuk memastikan bahwa switch dapat sembuh dengan cepat dan menyimpan server diakses oleh pengguna dalam hal link, switch atau kegagalan port.

Lab 7.3.6 Identifying Risks and Weaknesses in the Design
Task 1: Identify areas of risk and weakness in the server farm implementation
Step 1: Analyze the physical topology
Examine the server farm topology as one entity and as a part of the entire FilmCompany topology. Look for each of the risks and weaknesses listed in the chart. Describe the devices, connections, and issues that you find, or record None found if the design appears to avoid risks in that area.
| Weakness | Risk | Description of Location and Devices |
| Single point of failure | If a device fails, a portion of the network will be inoperable. | |
| Large failure domain | If a device or link fails, a large portion of the network will be affected | |
| Possible bottlenecks | If the traffic volume increases, thereis a potential for response time to
degrade. |
|
| Limited scalability | If the network grows more rapidly than expected, a costly upgrade will be needed. | |
| Overly-complex design | If the design is too complex, the current staff will not be able to support it properly. | |
| Other possibleweaknesses (specify): |
