Simple Network Management Protocol (SNMP) is part of IETF’s Internet Protocol Suite that consists of four abstraction layers and defines a set of protocols used on the Internet. SNMP is mainly used for management and monitoring of networked devices. It can inform about the health of a network device or other reflections of its state (interfaces, IP addresses, traffic and more). SNMP is defined as part of IETF RFC 1157. For its function, it leverages Management Information Bases (MIBs), which define the structure of device information maintained. They represent a hierarchical namespace containing object identifiers (OIDs). Each OID identifies an object that holds the information of interest and can be polled or set via SNMP.
What if your mobile device allowed you the freedom to seamlessly roam across any network in the world, regardless of location or operator and with all the attributes you would expect, security or privacy… With LISPmob, we may have gotten a giant step closer as we open sourced a network stack for network mobility on Linux platforms, an implementation of basic LISP mobile node functionalities.
This is the Locator Identifier Separation Protocol, which supports the separation of the IPv4 and IPv6 address space following a network-based map-and-encapsulate scheme based on an IETF open standard.
We hope this will be a project and a community many will find not just interesting and vibrant, but necessary and fun to engage, collaborate and contribute.
How will this help your plans to deal with all these amazing possibilities of mobile access to an ever-growing Internet?
Moving your network from IPv4 to IPv6 can be risky if you don’t close security holes
In February 2011, the last blocks of IPv4 Internet addresses were allocated, highlighting the need for organizations everywhere to plan their transition to IPv6, the next generation Internet protocol. Because the move to IPv6 is happening gradually, applications will support both Internet protocols for some time—and so must your network. During the transition from IPv4 to IPv6 your network could become vulnerable to new security risks, so it’s critical that you phase in the new protocol as securely as possible.
C’mon…didn’t you guys just do an IPv6 show back in 2007? Yes, and although many others have covered this ad-nauseum…(and we don’t run ads…) we thought it was high time we covered it TechWiseTV style…which means we got the details.
Watch it right now or keep reading for more details…
Specifically, we did not want to focus on big numbers or sky is falling stuff – its been done. We wanted to cover the actual reality of implementation.
If scare tactics still get you going…you know we have now officially run out of IPv4 addresses so I do think this topic has a new feeling of urgency.
The time for making educated decisions on your IPv6 migration can no longer be put off. Much has been learned about how to do this right and this one is all about asking the right questions and providing the right guidance.
Questions with the potential for long-term impact like:
As Mark Twain supposedly wrote, ‘rumours of my death have been greatly exaggerated’ – a phrase that certainly rings true for Cisco’s Catalyst 6500.
With a raft of new innovations recently announced at Cisco Live, competitors that were struggling to catch-up with the last iteration of this flagship switch have now seen their goalposts shift yet again.
The latest innovations provide Catalyst 6500 customers with the capability to evolve their network infrastructure for the coming decade’s proliferation of connected devices, growth of video traffic, cloud computing business models and increasingly mobile workforces—without requiring “rip and replace” upgrades.
So, once again, Cisco continues to deliver business-enhancing innovation and investment protection for its customers – and with a platform that many had wrongly assumed was dead. Amongst the enhancements announced were:
- Yet another ‘industry first’ with seamless IPv4 and IPv6 support from the switch’s hardware platform
- New network virtualisation capabilities
- A comprehensive set of L4-7 integrated services modules and new application performance and visibility monitoring through a revamped implementation of NetFlow.
The real key though is the introduction of the highly anticipated Cisco Catalyst 6500 Series Supervisor Engine 2T, a 2-terabit card that unlocks 80 gigabits per second per slot, new feature-rich 10-gigabit and 10-Gigabit Ethernet line cards, and next-generation borderless services that provide customers with new mobility, security, network analysis and load balancing capabilities.
The new supervisor engine provides a threefold increase on throughput capability. It can also quadruple the number of devices or users that can connect to a network. For example, a single Catalyst 6500 can now support up to 10,000 mobile devices.
All new line cards and the 2 Tbps supervisor are compatible with all Cisco E-Series chassis models, offering minimal intervention to the existing Catalyst 6500 E-Series infrastructure. This compatibility prevents rip-and-replace upgrades that jeopardize a customer’s network uptime and require additional personnel, expenses and time.
The video below features Kumar Srikantan, Cisco’s VP of Marketing for the Scalable Networks Business Unit, as he talks about the latest updates to the Catalyst 6500, why Cisco and our customers are so excited about them and what it means for the broader industry. Enjoy!
