Which ever method you use, you enter user exec mode first. User exec mode is one of three command exec modes in the IOS user interface. Enable mode, also known as privileged mode or Privileged exec mode, and command mode are the others. Enable mode is so named because the enable command is used to reach this mode.

User mode allows commands that are not disruptive to be issued, with some information being displayed to the user. Privileged mode supports a superset of commands compared to user mode. However, none of the commands in user mode or privileged mode changes the configuration of the router. Passwords are required for Telnet and auxiliary access as of Cisco IOS Release 12.x and later. However, there are no preconfigured passwords; therefore, you must configure passwords for Telnet and auxiliary access from the console first.

All Cisco routers have a console port, and most have an auxiliary port. The console port is intended for local administrative access from an ASCII terminal or a computer using a terminal emulator. The auxiliary port is intended for asynchronous dial access from an ASCII terminal or terminal emulator; the auxiliary port is often used for dial backup.

CCNA Security / ISCW Exam: Answer: Stateless packet filtering is generally referred to simply as packet filtering. Packet filtering works much like an ACL. It’s common to filter packets on one or more of the following:

1. Source IP address or port number
2. Destination IP address or port number
3. Protocol

Sounds great, right? There are some problems with this technique. Packet filtering only considers the values in the ACL – there’s no attempt to determine if this packet is part of an already-existing connection, or attempting to create one. With protocols that use random port numbers at times – FTP, for example – there can be some real problems establishing a connection.

Stateful packet filtering does monitor the connection state, and that’s particularly important when it comes to preventing TCP attacks. A stateful firewall will not only monitor the state of the TCP connection, but also the sequence numbers. Stateful firewalls accomplish this by keeping a session table, or state table.

BSCI: Answer: D. Two OSPF routers can be using different process numbers and still become neighbors.

BCMSN: Answer: A, C. DHCP Snooping is off by default, and when you enable it, all interfaces are untrusted.

ONT: Answer: To configure RTP Header Compression on this interface, enter the ip rtp header-compression command. In this example, IOS Help displays our options with this command.

R3(config)#int s0/0/0

R3(config-if)#ip rtp header-compression?

ietf-format Compressing using IETF format
iphc-format Compress using IPHC format
passive Compress only for destinations which send compressed headers

R3(config-if)#ip rtp header-compression

CCNA, Cisco Certification

No Comments

If a person has a CCNA certification, it means that he has the necessary skills that networking professionals use in installing, configuring, and troubleshooting routed and switched computer networks and systems. They are also capable of implementing and managing connections to remote sites using the WAN. Moreover, they are equipped with basic knowledge on network security issues, wireless computer networking, and other performance-based computer skills.

What is a CCNA certification?

CCNA stands for the Cisco Certified Network Associate (CCNA) certification. It is the entry-level certification of Cisco. Such is a pre-requisite for the other higher levels of Cisco certifications.

Basically the CCNA certification is the first step towards the series of Cisco IT certifications. It is best suited for IT help desk engineers, field technicians, computer networkers, and other IT professionals involved in managing the processes of computer networks.

What is the next step after getting a CCNA certification?

After an IT professional has gained the CCNA certification, he can then move forward and acquire the other Cisco Certifications. These include the CCNP (Cisco Certified Network Professional) certification which is designed for network administrators and network technicians; and CCIE (Cisco Certified Internetwork Expert) certification which is tailor made for senior network administrators and high level positions.

What are the topics that are included in the CCNA certification exam?

An individual aspiring for a CCNA certification should be knowledgeable with the basic history of networking. He should also be able to identify and utilize the OSI reference model and the basic principles used in network designs. Also, he should be able to construct and design both local-area networks (LANs) and wide-area networks (WANs). Knowledge on Ethernet and VLANs is also necessary as well as skills in IP addressing, and knowledge on TCP/IP protocols (ARP, RARP, BOOTP, and ICMP).

Moreover, the aspiring candidate should be proficient with routers and routing protocols, bridges, and switches. He should also be an expert with the Cisco IOS (Internetwork Operating System) and lastly, he should have prime knowledge on computer network management and security.

What other things should an aspiring CCNA know?

There are no pre-requisite tests for getting CCNA. Generally, the exam for the CCNA certification will last for two hours as it is only comprised of seventy eight questions.

In order to pass the exam, the aspiring candidate should be able to answer at least sixty three questions correctly. Also, before any individual can take the certification exam, he is required to pay an average of a hundred dollars as exam fee. Once the aspiring candidate pass, the results will be valid for three years. However, an official recertification exam should be taken at the end of the validity period.

How can one be prepared for a CCNA certification exam?

The aspiring individual should be able to get hands-on experience with computer systems, as well as formal IT trainings. In addition to that, an individual can opt to find an official Cisco Learning Partner. Such organizations will offer aspiring candidates with “live” preparation courses and materials.

If an IT professional cannot avail of actual training courses, he can study for the CCNA certification exam using books and online sources. Aside from step-by-step tutorials and lectures, an aspiring candidate can access comprehensive practice exams for the CCNA certification. In doing so, he can assess his present knowledge and capability to be CCNA certified.

No one will argue that the current economy is bad. As a consultant, I have noticed a significant decrease in project opportunities over the last 6 months ending 2008. The same has happened in the IT job market. Organizations are looking to cut cost. The question you have to ask yourself is “How can I survive in this environment?”

I believe the best thing any IT professional can do is increase their knowledge. One of the best ways to do that is to pursue a certification. I started my IT career working with Microsoft technology and then progressed into working with Cisco equipment. So I will narrow my comments to networking certifications.

When I first learned about certifications, I was going through a tough time in my career. I was out of work with very few prospects. I started researching different certification programs and was surprised to learn what Microsoft Certified System Engineers (MCSEs) and Cisco Internetwork Experts (CCIEs) were earning. That motivated me to purse first the MCSE and then CCNA, CCDA, CCNP, CCDP, CCSP, CCVP and then finally the CCIE. I can say without a shadow of a doubt, that it has been one of the best investment I have ever made. Each certification I have obtained has provided me with bigger and better career opportunities. It has also helped me differentiate myself from the competition.

Getting certified is not easy. It requires discipline and hard work, but there is a multitude of learning opportunities available today to help you reach your goal. You no longer need to purchase a bunch of lab equipment. You can rent online racks of equipment for a small fee. I personally believe that hands on is the best way to learn a subject. You also do not need to travel to take classes anymore. There are many companies offering online training classes and video-on-demand options.

If you are interested in getting certified, but are not sure which route to go, here are a few recommendations. Unified Communications is a growing field. Voice and video over IP is just getting started and there will continue to be a demand for qualified Engineers. Network Security is another good alternative. As more kinds of devices get connected to the internet, security concerns will continue to grow.

Here are a few of the certifications I recommend:

Unified Communications

o CompTIA Convergence+

o Cisco Certified Network Associate (CCNA)

o CCNA Voice

o Cisco Certified Voice Professional (CCVP)

o Cisco Certified Internetwork Expert (CCIE) Voice

Network Security

o CompTIA Security+

o CCNA

o CCNA Security

o CCSP

o CCIE Security

I challenge you to investigate which is the right certification for you and to get started now. You will not be sorry you did!

Cisco: We See our Future in the Smart Grid

Cisco Certification, News

No Comments

When you think Cisco, you generally think routers, not power plants. But increasingly, Cisco sees its future in the Smart Grid via a backdoor route — selling data center hardware to electric utilities. And that’s good news for anyone wanting to green their data center.

Cisco certainly isn’t ignoring selling products directly for the Smart Grid itself, including home devices to help people manage their electric use. As I’ve written in the past, Cisco expects that the Smart Grid use may even eventually dwarf the Internet.

But according to CNet, Cisco believes that utility companies will need to invest plenty of money in data centers in order to manage all the data that will be generated by the Smart Grid. Here’s what CNet says:

The tech giant is developing a suite of smart-grid products designed to add networking smarts to the existing grid, including routers for substations and home energy-monitoring systems. But a large chunk of the $20 billion per year in smart-grid spending that Cisco anticipates is in traditional data centers.

Since smart-grid technologies rely on a steady flow of information, Cisco expects that utilities will need to invest in more sophisticated IT systems, said Mark Weiner director of Data Center Solutions and a member of a Cisco smart-grid team.

The article goes on to note:

If utilities are regulated to reduce peak-time usage, their IT needs shoot up even higher. Demand response, where a utility can turn down energy use at participating customer sites, requires utilities to poll information regularly from a potential large number of locations.

“The requirements are for huge amounts of data to be involved when you have these more advanced pricing models where the goal is to mitigate power generation,” said Weiner. “The catcher’s mitt for that data is the data center.”

Why is this good news for anyone wanting to green their data center? Because most likely, specialized software and hardware will be developed for the interface between the Smart Grid and data centers, for use by electric utilities. But every data center, not just ones run by utilities, should benefit. And that means you.

Cisco and Unified Computing

The buzz about Cisco and their new approach of Unified Computing is building. As far as I’m concerned, it can’t arrive soon enough. The exact details are still pretty closely held, but from looking at Cisco Blog Post it is clear that Cisco is looking to make a big step in virtualizing the data center network.

This could be huge, in that it could fill in the last piece of the virtualization trinity. Server virtualization is now mainstream in the data center. The consolidation benefits are unquestioned and the ability to dynamically move workloads between compute resources is compelling if still a bit complicated. Storage is virtualized at some level on a wide scale, especially in the more modern architectures like Data ONTAP.

But the network has been a barrier to true dynamic mobility of applications and data since the VM typically has to make some assumption about a physical network address. On the storage side, volumes on iSCSI or file systems on NFS or CIFS are more dynamically addressed but they generally tend to stay in one place. This could change with a unified computing approach and systems like NetApp Data ONTAP 8 where volumes will move dynamically between nodes in a storage cluster but still be accessible at the same address.

Virtualizing the network with a unified computing approach frees up the last bond that had to be managed that tied applications and data together. In some ways, it is like the transition from a home phone number (tied to your house) to a cell phone number (always with you). Most people now are more easily accessible by cell since their “address” (phone number) moves with them. This kind of freedom of motion with continuity of access has transformed our day-day lives.

With the Cisco announcement, we have a unification of the hardware platform for virtualiztion that goes beyond blades, We see the IO paths, network and storage, integrated into the hardware platform in a hypervisor independent manner. The missing secret sauce is storage virtualization… I think NetApp will benefit from this.

In future network-based unified computing environments, VMware’s VMotion and NetApp’s Data ONTAP will bring a level of dynamic agility to the modern data center. When apps and data are not tied to physical systems, yet the network still finds them, is a situation that simplifies maintenance and change management dramatically. This approach could be a great partner to NetApp Unified Storage. Both focus on lowering the cost of operation of the data center and increasing the ability of the infrastructure to rapidly adapt to new business requirements.

Have done my CCIE Written for security now

As i was looking for something i could do next, after passing my ccie r&s, i took the security path next and last week, i did the written as a first step. It have been 105 question with a 790 points passing score. I managed to pass the test. It was quite close, i didn’t expect to pass. I was feeling i would fail, but tried my best and the last 10 – 15 questions and there must have been some correct answers.

With the new written in security i also recertified my r&s ccie for nearly the next 4 years now. The next time until i had to recertify is the 26.2.2013. Cisco just adds the new Written at the end of the first ending period. So that will take some time.

Since i read that the Security ASET Labs have been a great help for preparation, i have already booked some ASET Labs at the end of may until june. I know that for r&s they have been absolutly helpful and one of the best resources.

I still will look for some PEC courses for security. I found some for r&s with have been at least interesting. But the PEC www.cisco.com/go/pec was reorganized and the website changed a lot. I found it very difficult to get to the courses i have seen before.

I have to look again at the PEC. Might have been changed again.

I have booked the lab at the end of October in Brussels. But I’m unsure if this will be enough time for preparation. I will see. I had to decide until end of July. So until then, i will probably know more about, if it will work.

Currently i reorganize my testing environment also. Still was using a OpenSuse installation on my notebook. But i feel moving to another distribution. Might be Fedora or Ubuntu. Shouldn’t be a problem with dynamips on both. I have ordered a new HD with about 320 GB, so i will have more space available for my vmware installations. Still using my Lenovo T60 though. Have 3 GB of main memory, but i’m already looking for notebooks with more than 4 GB. I’m still waiting for.

If you wounder how often i could go on holiday, that nice time will shortly be over. I’m still on parental leave until midst of June and until then it have been 7 months altogether for me. My wife did the other 7 months before. Since 2007 in Germany it’s possible to parents sharing the time. And if one of them is taking at least two months, i will be 14 altogether, instead of only 12. It’s a great time with my son. He develops so quickly, for me it’s absolutely to quick. A few months ago, he was so small and now he is close to being able to walk already. It’s fantastic to see him every day and to experience his presence.
