Starting December 13, 2010 doesn’t get shocked for not downloading IOS images for any of your Cisco Products from Cisco Website. As of today if anyone having a valid SMARTNET contract with a valid CCO id can download IOS for any Cisco Catalyst Switches, Cisco Routers , Cisco security, voice and wireless products. It will not be same effective December 13, 2010. Cisco Systems is coming up with a new policy. All software download on Cisco.com will be verified against Products registered on your Services contract. Attempts to download Software for Products not registered on your Services contract will not be permitted.
Cisco Systems wants improve customer experience and protect your investments in Cisco Products. The major change is Cisco Systems will ask their customers to complete the following action before December 13, 2010
- Verify all applicable Cisco Products are covered under Cisco Service contracts, and that you have a valid license for Cisco Software.
- Verify your Services contracts are accurate and make necessary corrections – serial numbers, part ID’s and locations must be accurate on each Services contract.
- Associate all Services contracts to applicable Cisco.com user ID’s
- Verify all Cisco.com user IDs for your company are valid and properly assigned to individuals in your company.
So make sure all your SMARTNET and service contract are up to date and make sure you manage all your active contacts by associating with a valid Cisco.com user ID’s via the Service Access Management Tool (SAMT). This tool enables administrators to manage which individuals are allowed to request Service from Cisco (e.g. technical support/TAC, hardware replacement/RMA).
Cisco.com users can use the Cisco.com Profile Manager to view which Services contracts are associated to their profiles.
With introduction of the Cisco Carrier Packet Transport (CPT) System, Cisco Systems into packet optical transport system market. According to Cisco Systems the newly designed solutions assists for migrating service provider transport infrastructures to support next-generation IP-based services. Cisco claims this solution combines the reliability of the transport network with efficiencies of packet technology to deliver current and future services.

The Cisco Carrier Packet Transport System family includes the 6 RU CPT 600, the 2 RU CPT 200, and the CPT 50. This last pizza-box platform operates as a satellite to the CPT 600 or CPT 200, offering port extension up to 80 km away from its master platform. Ports on the CPT 50 are operated as if they were part of the master platform, says Cisco’s Stephen Liu.
The Cisco CPT system supports MPLS-TP Ethernet with quality of service and virtual local area network manipulation capabilities, as well as optical transport network and reconfigurable optical add-drop multiplexer functionality.
Currently the Cisco Carrier Packet Transport (CPT) System is in field trains with several service providers like Verizon in US and BT in UK and the scheduled date of availability is in the first quarter of 2011.

- Glenn Wellbrock, director optical transport network – architecture and design, Verizon
“Next-generation transport solutions should be clearly aimed at making packet transport suitable for carrier transport networks. Features such as standards-based operations, performance monitoring, administration, management, and sub-50-milliseconds protection switching are critical requirements in the Verizon packet transport network and we support Cisco’s decision.”
I hope by now you have made your mind to kick off your preparations for CCNP Routing and Switching Certification. And to start with you might have opted to go with Switch# 642-813 Exam and might have placed an order for CCNP Switch 642-813 Official certification guide from Cisco Press. Your CCNP Switch# 642-813 Exam companion.
The CCNP Switch 642-813 Official certification guide is an amazing title, which can trust for Switch # 642-813 Exam. The author David Hucaby CCIE 4594 carries an honor of writing many titles for Cisco Press especially when it come to switching he is master.
The CCNP Switch 642-813 Official certification guide comes with seventeen chapters covering wide range of topics
The first chapter emphasizes on the importance of planning for CCNP Switch# 642-813 Exam. In this chapter Cisco Systems have made very clear what they are anticipating for the CCNP Switching and Routing professional and what skill he/she should possess to be CCNP R & S.
In this chapter the author talks about Cisco’s approach to the life cycle of the Network, it is PPDIOO
Prepare - organizational requirements, strategy, financial justification
Plan - network requirements, gap analysis with existing network infrastructure, project plan
Design- design specification created (used for implement phase)
Implement – network is built, additional components added
Operate – maintaining network health, day-to-day operations
Optimize – proactive management, potential to spir network redesign
Tips for the implementation plan
The implementation plan consists of several phases ( for eg : installation of hardware, IOS check, configurations,-over to production, etc.). It is important to remember the following steps for each phase:
Description of the step
Reference to design documents
Detailed implementation guidelines
Detailed rollback guidelines in case of failure
Estimated time needed for implementation
Beginning of the year 2010 Cisco Systems announced major revamp in their most prestigious Cisco CCNP Certification. Before CCNP composed of BSCI, BSMCN, ISCW and ONT exams where as with the new announcement Cisco eased CCNP certification aspirers. The revised CCNP Switching and Routing gear comprises of just three exams, namely Router # 642-902 Exam, Switch#642-813 Exam and TSHOOT# 642-832 Exam.
When it comes to CCNP Routing and Switch Certification I personally prefer to start with Switch# 642-813 Exam. As switching exam should not be a hard exam for CCNA certified Network Engineer. The Switch # 642-813 exam tests your skills on following topics.
ü Network design, implementation, and verification plans
ü Switch operation and port configuration
ü VLANs, trunks, and VLAN Trunking Protocol (VTP)
ü Aggregating switch links
ü Spanning Tree Protocol (STP)
ü Multilayer switching
ü Enterprise campus network design
ü Router and supervisor redundancy
ü IP telephony
ü Wireless LANs
ü Switched network security
Now come the main question what resources you should use to pass the Cisco Switch#642-813 Exam, lot of resources are available, but when it come to self study guides Cisco Press is the leader and they come with pretty helpful titles.
To begin with you can start preparing with CCNP Switch 642-813 Official certification guide which can be easily ordered from Cisco Press watch out for eBook of day deal too who knows you can own the book for just 9.95 dollars. For non US residents no worries as Cisco Press ships world wide at very competitive shipping cost, seems that they have some deal with FEDEX as for the last four times when I ordered Cisco press titles they charged me 9 dollars for International shipping thru FedEx and it took 4 days to reach me. In upcoming posts I will try to review the CCNP Switch 642-813 Official certification guide in detail so that you folks can get benefited.

Most people were introduced to OSPF as the first link-sate routing protocol and some of the features of OSPF are as follows,
- Consists of areas and autonomous systems
- Minimizes routing update traffic
- Allows scalability
- Supports VLSM/CIDR
- Has unlimited hop count
- Allows multi-vendor deployment (open standard)
Do know these features well from CCNA point of view.
The below table compares OSPF with the distance vector routing protocols like RIP1 and RIP2
|Type of protocol||Link state||Distance vector||Distance vector|
|Route propagation||Multicast on change||Periodic multicast||Periodic broadcast|
|Hop count limit||None||15||15|
|Hierarchical network||Yes (using areas)||No (flat only)||No (flat only)|
|Updates||Event triggered||Route table updates||Route table updates|
If you are preparing for your CCNA or ICND2 certification exam for sure you are going to encounter OSPF. Open Shortest Path First (OSPF) is a better choice when you have a heterogeneous network, yes it’s a open standard routing protocol which over comes the major draw backs of Distance vector protocols like RIP 1 and RIP2. OSPF is a link state protocol, which can be quite useful on a large network with hundreds of routers.
Unlike Distance vector protocols OSPF will not exchange full route updates at short interval rather the routing updates are send once there is a change in routing topology. Using the Dijkstra algorithm,OSPF first constructs the shortest path tree and then the routing table is populated which results in best paths to the destination. Due to this behavior, OSPF is able to recalculate the routes very fast in case of topology changes or a failure in link occurred. One of the OSPF’s advantage is convergence occurs quite fast and its scalable. Currently OSPFv2 is used with IPv4 networks and IPv6 networks use OSPFv3. OSPF also supports Variable-Length Subnet Masking (VLSM) and Classless Inter-Domain-Routing (CIDR).
In upcoming post I will talk about how OSPF works? and I will compare it with RIP1 and RIP2
Recently I had an opportunity to go thru the CCNA study guide prepared and authored by Chris Bryant, the man behind the famous Train Signal CCNA Training videos. I know when any one plans for achieving CCNA Certification he faces an uphill task, when it comes to purchase the study guides, especially when there are plenty of resources available. I did studied lot of study guides and I am always very comfortable with the Cisco Press titles, but The Ultimate CCNA Study Package from Chris Bryant is really an ultimate study guide.
The best part I liked about The Ultimate CCNA Study Package is its very concise and its up to the point in a clear simple language. His way of explaining the Networking concepts is amazing and the end of the each chapter there is a summary by title “Hot spots and Gotchas” which is really very helpful.
