Hari ini ada temen minta di test kemampuan download dari koneksinya, dia sudah coba test download tapi tidak pernah sampai 40Mbps.. bahkan 20Mbps juga ga bisa…

Nah dari pengetesan tersebut akhirnya saya minta di sediakan mesin buat ujicoba, eh di kasih ubuntu ya udah deh akhirnya ngoprek di ubuntu, Langsung aja deh…

Install bittorrent kelar..

Upload file .torrent ke mesin-nya langsung dah jalanin :

Nah untuk monitoring-nya pake apps bmon aja :

Nah ini kalo mau ngitung MiB ke Mb, di ambil dari answers.yahoo

OK, there are 1024 KiB in a MiB.
In turn, there are 1024 bytes in a KiB.

So in a MiB there are

1024*1024 = 1,048,576 bytes.

There are 1000 KB in a MB.
In turn, there are 1000 bytes in a KB

So in a MB there are

1000*1000 = 1,000,000 bytes.

To convert from MiB to MB, multiply by 1.048576.
To convert from MB to MiB, divide by 1.048576.

Or just use 1.05, as that’s close enough, really.

If you want to convert between GiB and GB, use 1.073741824, or just 1.07.

For example, if you buy a new 500 GB hard drive, you only get about 465 GiB.

Kali ini saya coba berbagi pengetahuan dan semoga ini bisa bermanfaat bagi kita semua, dalam kesempatan ini saya coba menjelaskan cara-cara pembuatan port-channel lacp load balancing dan redudance
Apa sih itu LACP ?
LACP adalah kepanjangan dari Link Aggregation Control Protocol yang inti dari artinya adalah penggabungan beberapa port menjadi satu

Lalu apa itu Port-channel ?
Port-channel adalah Ethernet Channel of interfaces

kalau load balancing ?
load balancing adalah membuat seimbang, dimana dalam kasus ini kinerja dari port-nya balance

Lebih detail tentang teori baca aja deh di sini http://en.wikipedia.org/wiki/Link_aggregation

Lalu keuntungannya apa ?
Apa aja boleh… ^,^

Dari pada teori mulu mendingan kita praktek langsung aja ya..
Sekarang kita mulai configurasinya, tahap awal kita configurasi interface-nya, mari kita aktifin interface Port-channel-nya :
SW-Backbone-2#configure terminal
SW-Backbone-2(config)#interface port-channel 1
SW-Backbone-2(config-if)#description ke-SW-Backbone-1
SW-Backbone-2(config-if)#switchport trunk encapsulation dot1q
SW-Backbone-2(config-if)#switchport mode trunk
SW-Backbone-2(config-if)#switchport trunk allowed vlan 90,104,225
SW-Backbone-2(config-if)#CTRL+Z

lanjut aktifin load balance redudance-nya
SW-Backbone-2(config)#port-channel load-balance src-dst-ip

Ok..ini hasil dari configurasi di atas
SW-Backbone-2#show running-config interface po1
Building configuration…

Current configuration : 134 bytes
!
interface Port-channel1
description ke-SW-Backbone-1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 90,104,225
switchport mode trunk
end

SW-Backbone-2#sh ru
Building configuration…

Current configuration : 6063 bytes
!
! Last configuration change at 20:14:18 JKT Fri Dec 23 2011 by evan
! NVRAM config last updated at 19:32:28 JKT Fri Dec 23 2011 by evan

service timestamps log datetime msec localtime show-timezone
service password-encryption
service unsupported-transceiver
!
hostname SW-Backbone-2
!
port-channel load-balance src-dst-ip
!

lanjutttt… Sekarang kita alokasikan 4 port untuk kita gabungkan :
SW-Backbone-2#configure terminal
SW-Backbone-2(config)#in gi0/25
SW-Backbone-2(config)#description EthCnl-Po1
SW-Backbone-2(config-if)#switchport trunk encapsulation dot1q
SW-Backbone-2(config-if)#switchport mode trunk
SW-Backbone-2(config-if)#channel-group 1 mode active
SW-Backbone-2(config-if)#CTRL+Z
SW-Backbone-2#configure terminal
SW-Backbone-2(config)#in gi0/26
SW-Backbone-2(config)#description EthCnl-Po1
SW-Backbone-2(config-if)#switchport trunk encapsulation dot1q
SW-Backbone-2(config-if)#switchport mode trunk
SW-Backbone-2(config-if)#channel-group 1 mode active
SW-Backbone-2(config-if)#CTRL+Z
SW-Backbone-2#configure terminal
SW-Backbone-2(config)#in gi0/27
SW-Backbone-2(config)#description EthCnl-Po1
SW-Backbone-2(config-if)#switchport trunk encapsulation dot1q
SW-Backbone-2(config-if)#switchport mode trunk
SW-Backbone-2(config-if)#channel-group 1 mode active
SW-Backbone-2(config-if)#CTRL+Z
SW-Backbone-2#configure terminal
SW-Backbone-2(config)#in gi0/27
SW-Backbone-2(config)#description EthCnl-Po1
SW-Backbone-2(config-if)#switchport trunk encapsulation dot1q
SW-Backbone-2(config-if)#switchport mode trunk
SW-Backbone-2(config-if)#channel-group 1 mode active
SW-Backbone-2(config-if)#CTRL+Z

Di sini saya tidak memasukkan Allow Vlan ( filter vlan ) pada port yg kita gabung, melainkan cukup pada interface Port-channel-nya saja
Setelah di connectin semua maka hasilnya seperti ini :
SW-Backbone-2#show int status

Sekarang kita liat Speed-nya pada Interface Port-channel-nya sudah sebesar 4Gb ( MTU 1500 bytes, BW 4000000 Kbit, DLY 10 usec, ), dan di sini juga terlihat port berapa aja yg kita gabung ( Members in this channel: Gi0/25 Gi0/26 Gi0/27 Gi0/28 )

Kelar deh… gimana ? ada pertanyaan ?

Kadang kita suka males kalo mau backup switch, kalau hanya satu atau dua switch cisco sih ga begitu masalah.. kalau ada lebih dari 20 switch ? pasti merepotkan juga kan….

Nah karena dasar itu saya coba iseng-iseng bikin program asal-asalan, sebenernya ni program cuman buat ngebantu kita meng exekusi beberapa printah di cisco, seperti memasukkan user name, password, enable password, password enable, printah-printah backup seperti :

copy runing-config tftp:

copy vlan.dat tftp:

copy config.text tftp:

Nah untuk membuat tools ini memerlukan beberapa program yaitu :

1. Telnet client ( by default sudah ada pada windows anda, kecuali windows 7 harus di aktifkan program telnet cliant-nya )

2. AutoIT ( bisa di download di sini )

3. TFTP-Server ( bisa di download di sini )

Setelah Telnet Client , AutoIT dan TFTP-Server  di install sekarang ke proses selanjutnya yaitu pembuatan tools-nya contoh scrip-nya :

Ikuti petunjuk di scrip itu dan compile scrip tersebut dengan menekan CTRL+F7, setelah selesai siapkan TFTP-Server dan arahkan directory penyimpanannya. setelah semua selesai jalankan .exe yang tadi di compile.

Selamat Mencoba, semoga catatan kecil ini bisa bermanfaat buat kawan-kawan semua.

Niat… bila kita akan melakukan sesuatu harus kita Niatkan walaupun hal tersebut kita pikir susah bahkan sangat sulit, apabila kita Niatkan InsyaAllah semua menjadi mudah… dan petunjuk-Nya pasti nyata.

Perhatikan sekitar’mu dan sekeliling’mu tanda-tanda kebesan-Nya pasti menunjukkan jalan dan arahan, bahkan peringatan-Nya pun nyata.

Baik perbuatan Buruk maupun perbuatan Mulia pasti petunjuk-Nya nyata, tinggal kita harus peka terhadap petunjuk-Nya.

Yang paling nyata adalah petunjuk-Nya di dalam hati kita, lalu akan menunjukkan kesekitaran kita.

Perhatikan dan cermati setiap kejadian di sekitar kita.

Semoga kita semakin dekat dan peka terhadap kehendak-Nya.
