Why is it important to record baseline measurements of a prototype network?
Test results show security weaknesses after the baseline tests are run.
The baseline is the point at which the network is operating at its fullest potential.
Baseline measurements define a point at which network traffic has exceeded the designed capabilities of the network.
Test results are compared to the baseline to see how the test conditions increase processor use or decrease available bandwidth.*****

Penghitungan subnetting bisa dilakukan dengan dua cara, cara binary yang relatif lambat dan cara khusus yang lebih cepat. Pada hakekatnya semua pertanyaan tentang subnetting akan berkisar di empat masalah: Jumlah Subnet, Jumlah Host per Subnet, Blok Subnet, dan Alamat Host- Broadcast.
Penulisan IP address umumnya adalah dengan 192.168.1.2. Namun adakalanya ditulis dengan 192.168.1.2/24, apa ini artinya? Artinya bahwa IP address 192.168.1.2 dengan subnet mask 255.255.255.0. Lho kok bisa seperti itu? Ya, /24 diambil dari penghitungan bahwa 24 bit subnet mask diselubung dengan binari 1. Atau dengan kata lain, subnet masknya adalah: 11111111.11111111.11111111.00000000 (255.255.255.0). Konsep ini yang disebut dengan CIDR (Classless Inter-Domain Routing) yang diperkenalkan pertama kali tahun 1992 oleh IEFT.
Pertanyaan berikutnya adalah Subnet Mask berapa saja yang bisa digunakan untuk melakukan subnetting? Ini terjawab dengan tabel di bawah:
Subnet Mask Nilai CIDR
255.128.0.0 /9
255.192.0.0 /10
255.224.0.0 /11
255.240.0.0 /12

SUBNETTING PADA IP ADDRESS CLASS C
Ok, sekarang mari langsung latihan saja. Subnetting seperti apa yang terjadi dengan sebuah NETWORK ADDRESS 192.168.1.0/26 ?
Analisa: 192.168.1.0 berarti kelas C dengan Subnet Mask /26 berarti 11111111.11111111.11111111.11000000 (255.255.255.192).
Penghitungan: Seperti sudah saya sebutkan sebelumnya semua pertanyaan tentang subnetting akan berpusat di 4 hal, jumlah subnet, jumlah host per subnet, blok subnet, alamat host dan broadcast yang valid. Jadi kita selesaikan dengan urutan seperti itu:
1. Jumlah Subnet = 2x, dimana x adalah banyaknya binari 1 pada oktet terakhir subnet mask (2 oktet terakhir untuk kelas B, dan 3 oktet terakhir untuk kelas A). Jadi Jumlah Subnet adalah 22 = 4 subnet
2. Jumlah Host per Subnet = 2y - 2, dimana y adalah adalah kebalikan dari x yaitu banyaknya binari 0 pada oktet terakhir subnet. Jadi jumlah host per subnet adalah 26 - 2 = 62 host
3. Blok Subnet = 256 - 192 (nilai oktet terakhir subnet mask) = 64. Subnet berikutnya adalah 64 + 64 = 128, dan 128+64=192. Jadi subnet lengkapnya adalah 0, 64, 128, 192.
4. Bagaimana dengan alamat host dan broadcast yang valid? Kita langsung buat tabelnya. Sebagai catatan, host pertama adalah 1 angka setelah subnet, dan broadcast adalah 1 angka sebelum subnet berikutnya.
Subnet 192.168.1.0 192.168.1.64 192.168.1.128 192.168.1.192
Host Pertama 192.168.1.1 192.168.1.65 192.168.1.129 192.168.1.193
Host Terakhir 192.168.1.62 192.168.1.126 192.168.1.190 192.168.1.254
Broadcast 192.168.1.63 192.168.1.127 192.168.1.191 192.168.1.255
Kita sudah selesaikan subnetting untuk IP address Class C. Dan kita bisa melanjutkan lagi untuk subnet mask yang lain, dengan konsep dan teknik yang sama. Subnet mask yang bisa digunakan untuk subnetting class C adalah seperti di bawah. Silakan anda coba menghitung seperti cara diatas untuk subnetmask lainnya.
Subnet Mask Nilai CIDR
255.255.255.128 /25
255.255.255.192 /26
255.255.255.224 /27
255.255.255.240 /28
255.255.255.248 /29
255.255.255.252 /30
SUBNETTING PADA IP ADDRESS CLASS B
Berikutnya kita akan mencoba melakukan subnetting untuk IP address class B. Pertama, subnet mask yang bisa digunakan untuk subnetting class B adalah seperti dibawah. Sengaja saya pisahkan jadi dua, blok sebelah kiri dan kanan karena masing-masing berbeda teknik terutama untuk oktet yang “dimainkan” berdasarkan blok subnetnya. CIDR /17 sampai /24 caranya sama persis dengan subnetting Class C, hanya blok subnetnya kita masukkan langsung ke oktet ketiga, bukan seperti Class C yang “dimainkan” di oktet keempat. Sedangkan CIDR /25 sampai /30 (kelipatan) blok subnet kita “mainkan” di oktet keempat, tapi setelah selesai oktet ketiga berjalan maju (coeunter) dari 0, 1, 2, 3, dst.
Subnet Mask Nilai CIDR
255.255.128.0 /17
255.255.192.0 /18
255.255.224.0 /19
255.255.240.0 /20
255.255.248.0 /21
255.255.252.0 /22
255.255.254.0 /23
255.255.255.0 /24
Subnet Mask Nilai CIDR
255.255.255.128 /25
255.255.255.192 /26
255.255.255.224 /27
255.255.255.240 /28
255.255.255.248 /29
255.255.255.252 /30
Ok, kita coba dua soal untuk kedua teknik subnetting untuk Class B. Kita mulai dari yang menggunakan subnetmask dengan CIDR /17 sampai /24. Contoh network address 172.16.0.0/18.
Analisa: 172.16.0.0 berarti kelas B, dengan Subnet Mask /18 berarti 11111111.11111111.11000000.00000000 (255.255.192.0).
Penghitungan:
1. Jumlah Subnet = 2x, dimana x adalah banyaknya binari 1 pada 2 oktet terakhir. Jadi Jumlah Subnet adalah 22 = 4 subnet
2. Jumlah Host per Subnet = 2y - 2, dimana y adalah adalah kebalikan dari x yaitu banyaknya binari 0 pada 2 oktet terakhir. Jadi jumlah host per subnet adalah 214 - 2 = 16.382 host
3. Blok Subnet = 256 - 192 = 64. Subnet berikutnya adalah 64 + 64 = 128, dan 128+64=192. Jadi subnet lengkapnya adalah 0, 64, 128, 192.
4. Alamat host dan broadcast yang valid?
Subnet 172.16.0.0 172.16.64.0 172.16.128.0 172.16.192.0
Host Pertama 172.16.0.1 172.16.64.1 172.16.128.1 172.16.192.1
Host Terakhir 172.16.63.254 172.16.127.254 172.16.191.254 172.16.255.254
Broadcast 172.16.63.255 172.16.127.255 172.16.191.255 172.16..255.255
Berikutnya kita coba satu lagi untuk Class B khususnya untuk yang menggunakan subnetmask CIDR /25 sampai /30. Contoh network address 172.16.0.0/25.
Analisa: 172.16.0.0 berarti kelas B, dengan Subnet Mask /25 berarti 11111111.11111111.11111111.10000000 (255.255.255.128).
Penghitungan:
1. Jumlah Subnet = 29 = 512 subnet
2. Jumlah Host per Subnet = 27 - 2 = 126 host
3. Blok Subnet = 256 - 128 = 128. Jadi lengkapnya adalah (0, 12 8)
4. Alamat host dan broadcast yang valid?
Subnet 172.16.0.0 172.16.0.128 172.16.1.0 … 172.16.255.128
Host Pertama 172.16.0.1 172.16.0.129 172.16.1.1 … 172.16.255.129
Host Terakhir 172.16.0.126 172.16.0.254 172.16.1.126 … 172.16.255.254
Broadcast 172.16.0.127 172.16.0.255 172.16.1.127 … 172.16.255.255
Masih bingung juga? Ok sebelum masuk ke Class A, coba ulangi lagi dari Class C, dan baca pelan-pelan

Kalau sudah mantab dan paham, kita lanjut ke Class A. Konsepnya semua sama saja. Perbedaannya adalah di OKTET mana kita mainkan blok subnet. Kalau Class C di oktet ke 4 (terakhir), kelas B di Oktet 3 dan 4 (2 oktet terakhir), kalau Class A di oktet 2, 3 dan 4 (3 oktet terakhir). Kemudian subnet mask yang bisa digunakan untuk subnetting class A adalah semua subnet mask dari CIDR /8 sampai /30.
Kita coba latihan untuk network address 10.0.0.0/16.
Analisa: 10.0.0.0 berarti kelas A, dengan Subnet Mask /16 berarti 11111111.11111111.00000000.00000000 (255.255.0.0).
Penghitungan:
1. Jumlah Subnet = 28 = 256 subnet
2. Jumlah Host per Subnet = 216 - 2 = 65534 host
3. Blok Subnet = 256 - 255 = 1. Jadi subnet lengkapnya: 0,1,2,3,4, etc.
4. Alamat host dan broadcast yang valid?
Subnet 10.0.0.0 10.1.0.0 … 10.254.0.0 10.255.0.0
Host Pertama 10.0.0.1 10.1.0.1 … 10.254.0.1 10.255.0.1
Host Terakhir 10.0.255.254 10.1.255.254 … 10.254.255.254 10.255.255.254
Broadcast 10.0.255.255 10.1.255.255 … 10.254.255.255 10.255.255.255
Mudah-mudahan sudah setelah anda membaca paragraf terakhir ini, anda sudah memahami penghitungan subnetting dengan baik. Kalaupun belum paham juga, anda ulangi terus artikel ini pelan-pelan dari atas. Untuk teknik hapalan subnetting yang lebih cepat, tunggu di artikel berikutnya
Catatan: Semua penghitungan subnet diatas berasumsikan bahwa IP Subnet-Zeroes (dan IP Subnet-Ones) dihitung secara default. Buku versi terbaru Todd Lamle dan juga CCNA setelah 2005 sudah mengakomodasi masalah IP Subnet-Zeroes (dan IP Subnet-Ones) ini. CCNA pre-2005 tidak memasukkannya secara default (meskipun di kenyataan kita bisa mengaktifkannya dengan command ip subnet-zeroes), sehingga mungkin dalam beberapa buku tentang CCNA serta soal-soal test CNAP, anda masih menemukan rumus penghitungan Jumlah Subnet = 2x - 2

AAA Financial Services Company is performing implementation planning for a core switch upgrade. The company has 200 financial software programmers that work billable hours during the week. They have critical, scheduled money transfer transmissions that occur at hourly intervals every night. There are two, two-hour long IT maintenance windows scheduled for software upgrades, one on Saturday and one on Sunday. The bank advertises online banking as available 24 hours on business days and 21 hours on the weekends. However, a network upgrade that is necessary to replace some switches is expected to take four hours. Because of rack constraints, this time includes three hours to remove the old switches before the new switches can be installed and one hour to test the logical configuration. How should the implementation scheduling be handled?
Defer the software upgrades. Use the Saturday window to perform the hardware installation. Use the Sunday window to perform the logical testing.
Coordinate and publish a separate four-hour downtime during Friday to perform the complete switch installation and testing process. Use the Saturday and Sunday windows to correct any outage problems after the Friday window.
Coordinate and publish two, four-hour downtimes incorporating the published Saturday and Sunday windows. Defer any software upgrades until the new network is proven to be working correctly with the old software. Use the Sunday window as a fallback scheduling period if there are problems necessitating backing out of the Saturday window.
Coordinate and publish an eight-hour downtime incorporating the Saturday window. This will allow four hours for installation and logical testing, one hour for troubleshooting and decision, and three hours to roll back to the previous configuration if the new switching cannot pass the logical testing. Defer any software upgrades until the new network is proven to be working correctly with the old software. ****
