Emerging markets such as China, India, Indonesia, Malaysia, the Philippines, Thailand, Latin American countries, Eastern Europe, and Middle East and Africa will double those from mature markets (135 million vs.62 million respectively).


By end of this year one in five household worldwide will have a fixed broadband connections (DSL, Cable Modem, etc).


In 2009, 442 million household are benefited with the broadband connection and the market is expected to grow nearly 580 million in the next few years.


“Broadband services represent the core of all fixed-line household communications services; hence, communications providers will be able to continue their reliance on broadband subscription revenue to offset revenue loss from other services in their portfolio offerings,” Ms. Sabia said. “Equipment manufacturers (modems, routers and PCs) and providers of carrier infrastructure will benefit by having more connections to supply equipment and services to. Government, medical and educational institutions alike will have alternative access to their customers via the household broadband connection.”

How to configure Trunking between a Cisco Catalyst and a 3Com SuperStack?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


I am writing this article to answer the question  for establishing the trunking between a Cisco Catalyst Switch and a 3Com Super Stack Switch in ITKE community.


The goal of the article is show the user how to configure an inter operable trunk port in both Cisco and 3 Com Switch. As far as trunking concepts are concerned I did posted an article in ITKE blog comparing the HP Procurve and a Cisco Catalyst Switches which help to understand the trunking methodologies applied in 3 Com and Cisco Switches.

In order understand the configuration process easily I present a scenario, based on this scenario we will configure the Cisco and 3 Com Switches to meet the objectives.


In this example 

·         A Cisco Catalyst Switch is connected to a 3-Com Super Stack 4200 Switch (3-Com Super stack 3300 configuration is also available as the configuration process defers in a 3300 Switch)) using a port fast /Giga Ethernet 1 in both the Switches.

·         Create two VLANS locally in both the Cisco Catalyst Switch and a 3-Com Super Stack 4200.

1.       VLAN 100 – For Workstations (named PCS).

2.       VLAN 200- For Servers and Management Devices (Named MANG).

·         Configure fast Ethernet 0/1 on both the Cisco Catalyst Switch and a 3-Com Super Stack 4200 as 802.1 q trunking port.


Cisco Catalyst Switch Configuration Example


Task 1 – Create VLANS


ITKE-Cisco#configure t

Enter configuration commands, one per line.  End with CNTL/Z.

ITKE-Cisco(config)#vlan 100

ITKE-Cisco(config-vlan)#name PCS   


ITKE-Cisco(config)#vlan 200

ITKE-Cisco(config-vlan)#name MANG


Task 2 – Configure the port fastethernet 0/1 as 802.1 q trunk port.


ITKE-Cisco(config)#interface fastEthernet 0/1

ITKE-Cisco(config-if)#description Connected to 3-COM Switch

ITKE-Cisco(config-if)#switchport trunk encapsulation dot1q

ITKE-Cisco(config-if)#switchport mode trunk

ITKE-Cisco(config-if)#no shutdown



Task 3 – Configure the ports fastethernet 0/5 for VLAN 100 and fastethernet 0/10 for VLAN 200.

ITKE-Cisco(config)#interface fastEthernet 0/5

ITKE-Cisco(config-if)#description Connected to PC


ITKE-Cisco(config-if)#switchport mode access

ITKE-Cisco(config-if)#switchport access vlan 100


ITKE-Cisco(config)#interface fastEthernet 0/10

ITKE-Cisco(config-if)#description Connected to SERVER

ITKE-Cisco(config-if)#switchport mode access

ITKE-Cisco(config-if)#switchport access vlan 200


3-Com Super Stack 4200 Switch Configuration Example (Configuration steps are as per the 3-Com Advance configuration manualnot tested).

Task 1 – Create VLANS and add ports Giga Ethernet 0/5 for VLAN 100 and Giga Ethernet 0/10 for VLAN 200


<SwitchB> system-view

[SwitchB] vlan 100

[SwitchB-vlan100] description PCS

[SwitchB-vlan100] port GigabitEthernet 1/0/5

[SwitchB-vlan100] quit


Create VLAN 200, and add GigabitEthernet1/0/10 to VLAN 200.

[SwitchB] vlan 200

[SwitchB-vlan200] description MANG

[SwitchB-vlan200] port GigabitEthernet 1/0/10

[SwitchB-vlan200] quit



Task 2 – Configure the port Gigaethernet 1/0/1 as a trunk port.


[SwitchB] interface GigabitEthernet 1/0/1

[SwitchB-GigabitEthernet1/0/1] port link-type trunk


3-Com Super Stack 3300 Switch Configuration Example.

Task 1 – Create VLANS

Select menu option (bridge/vlan): create

Select VLAN ID (2-4094)[3]: 100

Enter VLAN Name [VLAN 10]: PCS


Select menu option (bridge/vlan): create

Select VLAN ID (2-4094)[3]: 200

Enter VLAN Name [VLAN 11]: MANG



Task 2 – Configure the port fastethernet 0/1 as 802.1 q trunk port

Select VLAN ID (1-2,) [1]: 100 – 200

Select bridge ports (AL1-AL4,unit:port…,?): 1:1

Enter tag type (untagged,tagged): tagged


Task 3 – Configure the ports Giga Ethernet 0/5 for VLAN 100 and Giga Ethernet 0/10 for VLAN 200


Select menu option (bridge/vlan/modify): add

Select VLAN ID (1-2,)[1]: 100

Cisco Press launches new title addressing FCoE standard

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


In one of my older post in June I was just taking about the FCoE (Fiber Channel over Ethernet) as a standard. Cisco Systems was one of the major contributors to establish the FCoE Standard.  Like a responsible vendor now Cisco Press has come up with a new title I/O Consolidation in the Data Center. This title is a fully updated version of Silvano Gai’s privately-published book on FCoE, written for leading FCoE pioneer Nuova Systems before the company was acquired by Cisco. Nearly 12,000 copies of that book have already been distributed, demonstrating the immense interest in FCoE technology, and the scarcity of reliable information that has existed about it.

The new title I/O Consolidation in the Data Center deals with the recently approved FCoE standard. According Cisco Press Senior Publicist Jamie Adams the new title comprises of five detail case studies illustrating typical FCoE adoption scenarios, as well as extensive Q & A section addressing issues raised quite often by the Enterprise IT professionals.

For more details do check out the Cisco Press product description.

Microsoft Unveils Thinnest Keyboard!

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


Recently I was browsing a press release from Microsoft about the thinnest keyboard ever available, which is slightly thicker than an AAA battery.

Pic Courtesy: Microsoft


The newly designed keyboard is exclusively for Bluetooth computers, and Microsoft called this keyboard as Mobile Keyboard 6000. The Mobile Keyboard 6000 comes with a ‘Comfort Curve’ that gives your wrists a rest with a slight 6-degree curve. While it might not seem like a big deal, Microsoft has already sold more than 10 million of its Comfort Curve keyboards so there’s definitely a wrist-concerned market out there.  One more unique feature of Mobile Keyboard 6000 is number pad can be separated and used separately.


Microsoft will be selling the Mobile Keyboard 6000 next month for $89.95. But if it’s just the Number Pad you’re after, you’ll need to spend $44.95.

Review for the CCNP BSCI Official Exam Certification Guide, Fourth Edition

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

I am always inspired by the Cisco Press books which are my only source for my career success. When it comes to certification study guides, Cisco Press leads from the front.  In this article I will try to review the CCNP BSCI Official Exam Certification Guide, Fourth Edition, this study guide is a first and final step towards your CCNP success.


As promised by Cisco Press the CCNP BSCI Official Exam Certification Guide, Fourth Edition, is indeed a best breed of Cisco® exam study guide which specifically focuses on the objective of CCNP BSCI 642-901 exam. The study guide comprises of over 600 pages divided into 21 chapters.  Which covers essential routing principles, EIGRP, OSPF and IS-IS in dept as well as basic BGP configuration.


The study guide has concentrated a bit more on Multicasting and multicast routing and the IPv6 is explained well but not in too dept.  The best part I liked about the CCNP BSCI Official Exam Certification Guide, Fourth Edition, is the Cisco IOS® routing features.


The CCNP BSCI Official Exam Certification Guide, Fourth Edition, comes with a companion CD from boson which consists of an electronics books and more than 200 practice questions which also included simulation-bases questions available in study mode, practice mode and flash card format.


Some of the features which I liked most in the CCNP BSCI Official Exam Certification Guide, Fourth Edition,   “Do I know this already?” quizzes and “Foundation Summaries” that start off each chapter. These allow the reader to assess what they already know about an upcoming section and what they need to focus on. The end-of-chapter “Q&A” will solidify any knowledge you have gained or need to review. Also the scenarios provided at the end of the chapters are worth from exam point of view.


Overall a good supplement for the exam, but the CCNP BSCI Official Exam Certification Guide, Fourth Edition, cannot be a sole resource for the exam. It’s always good to use the resources available at the Cisco learning websites.  Finally I would rate 4 out of 5 for this study guide. Better luck folks and hope to see you all passing the CCNP BSCI 642-901 exam at first attempt.

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Yesterday I received an email from the Area Manager Mohammed Fazal, of the leading Swiss cabling specialist, Reichle & De-Massari. According to his email R & M unveiled a major breakthrough in copper cabling, a new RJ45 connection module which meets the Cat. 6A standard as specified by ISO/IEC had been launched.


Jean Pierre Labry, managing director of R&M Middle East & Africa, said: “Cat 6A is the key to new maximum performance and greater operating reliability in data networks.”


He also added that the new devices allow companies to boost their network’s bandwidth and transmission quality without having to abandon the reasonably-priced and reliable RJ45 connector standard.





In a recently held Ineltec conference in Basel R & M unveiled the high speed RJ45 connection module.


The R & M development lab has discovered a new way of shielding individual twisted pairs from electromagnetic interference and the company claims the new devices will be suitable for transmission of data at speeds greater than 10Gbps.

Also check the press release from R & M.

The new research sponsored by Brockade and Eaton suggests still data centers are being driven by performance issues.
