Cisco’s Nexus is a Big Big Deal

October 30 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco News

It's hard to overstate how important the Nexus data-center switching platform, set to be unveiled Monday, is to Cisco Systems: for the dominant networking vendor's enterprise business, it's the biggest thing since the Catalyst 6000, which made its debut in 1999, according to the two key executives on the project.


At a dinner with press last week, they compared it to the CRS-1 (Carrier Routing System), a huge switch for the core of carrier networks that Cisco rolled out in 2004. To bring that platform to life, the company developed a new version of its flagship IOS (Internetworking Operating System) software and engineered the hardware to scale up to 92Tbps of throughput. The core of the Internet is Cisco's turf, and it wasn't willing to give any ground to upstarts.


The Nexus brings Cisco into not just a new territory for its business, but a new product category: a unified switch that spans storage and computing in data centers and has security built in. Given the stakes, superlatives are natural.


- A single Nexus chassis will be able to handle more than 15Tbps of traffic ripping through a data center, up from just 2Tbps for a current Catalyst 6500 switch.


- At that rate, the switch could run 5 million concurrent transcontinental conferencing sessions using Cisco's TelePresence Collaboration system. It could also copy the entire searchable Internet in 7.5 minutes.


- One interface module for the Nexus 7000 chassis will come with 32 10Gbps ports, and the platform is designed to support future interfaces including 100Gbps.


- The company spent about $250 million on research and development for the new platform, and at its peak, the Nexus R&D team numbered more than 500 engineers, according to Tom Edsall, senior vice president and chief technology officer of Cisco's Data Center Business Unit.


As with the Catalyst 6000 Series and the CRS-1, Cisco developed the Nexus with an eye to long-term needs. Where the CRS marked the debut of IOS XR, the first modular version of IOS, the Nexus will have Cisco's first OS that can be fully virtualized, called NX-OS. The Nexus will also break new ground with its lossless switching fabric, a departure from traditional Ethernet -- though backward compatible with it, Cisco said.


The system also represents a gamble on FCoE (Fibre Channel over Ethernet), a still-emerging standard for sending traditional Fibre Channel storage network traffic over Ethernet. Though the new standard will probably succeed with the backing of Cisco and other big vendors, the installed base of Fibre Channel is huge, said Yankee Group analyst Zeus Kerravala. There will be a proving period for Ethernet as a reliable, lossless data center transport, he said.


Cisco expects the uptake of the new platform to take time, just as it did with the CRS. The first Nexus product will go on sale in the second quarter of this year, and in the first year Cisco expects to see mostly trials of the new system, said Jayshree Ullal, senior vice president of Cisco's data center group. Deployments will probably start to pick up in the second, third and fourth years after the introduction, she said.


But just as the opportunity was huge for the CRS, as video and other traffic rose fast on carrier networks, the chance to capture next-generation data centers is likely to justify Cisco's efforts on the Nexus line. Web-based services and applications, as well as outsourced computing offerings from Amazon.com and other companies, are powering the growth of massive data centers. Microsoft's MSN division is a test customer of the Nexus, said Ullal. Asked whether the mighty Google would buy in as well, Ullal said, "I would hope so."

Three Big Reasons to Buy Cisco

October 25 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco News

While Cisco Systems has put up lackluster results thus far this year – down just over 1% on a year-to-date basis as of this writing– there are some significant reasons to buy this stock at current levels. To begin with, even as analysts wrongly try to reclassify Cisco as a value stock, the company is undervalued across various metrics. Additionally, through important strategic partnerships with players like VMware, the company continues to have significant growth potential.  Finally, despite the negative press the company has received over its deal with ZTE, the relationship is not critical to Cisco and the news will continue to fade. Ultimately, Cisco offers real growth while trading at a value multiple and paying a healthy “value-stock” dividend. The stock is a strong buy for your core portfolio.


The Valuation Question

At current levels, Cisco is trading at a trailing P/E of 12.5 and a forward P/E of 9. Competitors are trading at much higher multiples, including Juniper Networks with a trailing P/E of 36.5 and a forward P/E of 15.6. Those figures are without the benefit of the 3% dividend offered by Cisco. The respective PEG ratios for the two companies are 1.21 for Cisco and 1.57 for Juniper, so even with the growth element included, Cisco is more attractive.


It’s not that I wouldn’t prefer to own a smaller company trading at a higher multiple with less growth and no dividend, but the analysts tell me that Juniper is a growth stock and Cisco has become a value stock. Sarcasm aside, on a valuation basis – regardless of whether we choose to call Cisco a growth stock or a value stock – the networking juggernaut is a better value at current levels than its peers. On this consideration alone, Cisco is a buy.


Strategic Alliances

Arguably the most important partnership that Cisco currently has in place to target future growth is the alliance it has forged with VMware. The two companies are collaborating on a variety of projects, but the software-defined data center is amongst the most critical. When the VMware CEO was recently interviewed in conjunction with his company’s acquisition of Nicira, he admitted that as the company looks to transition the network space from hardware-based to software-based, its relationship with Cisco would change. He went on to add,” Does it change our relationship with Cisco? Well, certainly, but we are reviewing this as a positive opportunity to create more partnerships with them.”


Not that one would expect a CEO that has forged a partnership with a 70% market share player like Cisco to come out and say he plans to run them into the ground, but the nature of the relationship itself suggests otherwise. The software-defined data center is being developed by a team that is funded by the two companies, but is being run independently. As the market shifts and acquisitions are made, the relationship will evolve, but Cisco’s close ties with VMware is a second reason to own the stock.


Dying Hype

One drag this year on Cisco shares has been the negative press the company received over the end of its sales relationship with Chinese ZTE Corp. The probe, that dates back to the early part of this year, uncovered that the Chinese affiliate had sold Cisco made products inside Iran. The fallout has sparked investigations by the FBI and several Congressional committees charged with addressing security concerns. The relationship between the two companies is said to have been tense for some time, so this development may actually give the company a needed out to end the relationship. While Cisco is not reliant of this relationship, having your company name mentioned in the same sentence as “concerns over national security” can cast a pall over the stock. This cloud is dissipating, however, and this should serve as a third reason to buy Cisco.

Overall, Cisco presents investors with a myriad of reasons to own shares at current levels. 


Foolish Bottom Line

Cisco Systems has had a lot of movements both up and down, but is today's rise a sign of further gains to come?

Cisco Said to Cut Ties with China's ZTE

October 16 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco News

Follows investigation into sales to Iran

Cisco has reportedly cut ties with Chinese telecom vendor ZTE after allegations that ZTE sold Cisco gear to Iran.


In June, a Reuters story revealed that Cisco, HP and Oracle gear was being sold to an Iranian mobile operator despite U.S. government sanction on such sales. Cisco conducted an internal investigation into ZTE's practices and as a result, recently ended a longstanding relationship with the Chinese company, according to a Reuters story published this week.


The Cisco/ZTE situation comes amid a report due today from the U.S. House Intelligence Committee that states that equipment from ZTE and fellow Chinese telecom company Huawei pose a security threat to the U.S. The report, which follows a year-long investigation, recommends the U.S. block any attempts by ZTE and Huawei to make acquisitions or mergers in America, and encourages U.S. firms to procure equipment from other sources.


A ZTE spokesperson said of the Cisco action that the company is "highly concerned" and "communicating" with Cisco, according to Reuters. The spokesperson also said ZTE is cooperating with the U.S. government on its investigation into sales to Iran.


Cisco did not comment by the time this story was posted. But in June, Cisco said it "... complies with all U.S. export laws and requires our business partners to expressly acknowledge that they too must abide by these laws. Products such as these, which are not subject to individual export licenses, can be purchased from distributors and resold without Cisco's knowledge or control. We continue to investigate this matter, as any violation of U.S. export controls is a very serious matter."


According to this week's Reuters story, ZTE's general counsel at its Texas-based subsidiary alleged that the parent company plotted a cover-up of the sale of Cisco gear to Iran, including possibly shredding documents. The FBI has launched a criminal probe into the allegations, the news service reports.


ZTE has continued to do business in Iran while American-made technology has been subject to U.S. sanctions. A parts list dated July 2011 for an equipment contract between ZTE and an Iranian telecommunications company included several Cisco switches, Reuters reports. ZTE later agreed to sell five Cisco switches to another Iranian firm, according to the news service.


Cisco and ZTE partnered for the past seven years. Cisco viewed ZTE as a means to combat Huawei, which had been beating out Cisco in emerging markets by offering significantly cheaper products, according to Reuters.


But ZTE wanted to expand into the U.S. and Cisco did not want that, according to the Reuters report, which quoted "a former Cisco executive with knowledge of the matter."

Cisco and NetApp Waggle Shrunken ExpressPod at Hitachi and Friends

October 12 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco News

Get a load of our converged convergement

VMworld It looks like the vendors are sizing each other up for battle in the converged systems world at VMworld: NetApp and Cisco have announced ExpressPod, a pre-packed and tested and downsized FlexPod. Storage clustering has been added into the FlexPod mix and Oracle has announced an RAC/VMware FlexPod.


Just one day after Hitachi's converged UCP platform was announced, NetApp and Cisco have upped the converged systems' ante and moved downmarket with their ExpressPod as well as boosting existing FlexPods.


The ExpressPod is for small and medium business (SMB) and includes:


NetApp ExpressPod at VMWorld Barcelona

The data centre-class FlexPod converged systems now support vSphere on ONTAP 8 cluster mode, meaning customers can simply add more NetApp storage to a FlexPod configuration to grow the storage pool size. The storage pool supports multi-tenancy and dynamic allocation, good for cloud service providers.


Clustering also supports non-disruptive migration of data from old to new arrays, data that could be hundreds of running virtual machines. This aids load-balancing, system maintenance and upgrades.


Oracle RAC databases can now run on VMware FlexPods, inheriting all the existing FlexPod goodness.


NetApp says that there are now in excess of 1,300 customers after just under two years of availability, plus more than 600 certified FlexPod partners who have access to a Cisco/NetApp help desk for system planning, design and implementation.


By moving down into the small and medium biz (SMB) space, NetApp and Cisco are encroaching into the existing SMB businesses of Dell, HP and IBM. We might expect that Hitachi and EMC will respond to NetApp with low-end branded converged system offerings of their own.


EMC's Eric Herzog, SVP for product management and marketing, says EMC is already present in the SMB converged system space with VSPEX, since it comes in a VNXe version.


One thought: by having converged systems dedicated to specific applications, such as the RAC FlexPod and HDS's UCP Select application-specific offerings we are seeing the introduction of converged system app execution stack silo systems. Whether this is a bad thing or not depends upon future needs for general purpose systems.


 ExpressPods will be available from NetApp and Cisco partners in November.

What Hardware Vendor IPv6 Support

October 11 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Networking

There are many tested IPv6 networks deployed across the world. For actual deployment, however, all the companies need to ensure that the vendors who support companies’ network have the requisite IPv6 enhancements.IPv6-Hardware-Vendor-Support.jpg


There are two categories of IPv6 enhancements. The first is the set that supports the packet forwarding (more commonly referred to as routing) process and the other set comprises enhancements that support the computing or host infrastructure.


IPv6 enhancements of the first category include larger address formats (the ones that affect the routing table size and structure), better routing protocols such as Open Shortest First Protocol (OSPF) and Routing Information Protocol (RIP), and good support for optional extension headers (which streamline the packet forwarding process) such as the Routing Header. And, the second category of enhancements comprises enhancements to the Domain Name System (DNS), the Stateless Auto-configuration (plug and play) process, upgraded Security, and updates to the Application Programming Interfaces (APIs).


Keeping these requisite enhancements in mind, let us now discuss what kind of support ten of the premier networking vendors are equipped to provide:


Apple Computer

The open source, UNIX-based OS X operating system from Apple Computer allows for advanced BSD networking and has a TCP/IP stack and advanced sockets. Versions 10.2 and later of this operating system provide good support for IPv6.


Cisco Systems

As this vendor has been actively involved in the development of IPv6, it provides very good support for IPv6. In fact, the vendors support for IPv6 can be observed in all its products. Further, the documentation of IOS 12 has extensive details of the IPv6 features, such as Automatic and Configured tunneling, BGP extensions for IPv6, MTU Path Discovery, Neighbor Discovery, updated routing protocols, and Stateless Auto-configuration, supported in each platform.



The new HP-UX11i provides support for several IPv6 features such as automatic and configured tunnels, advanced and basic sockets application programming interfaces (APIs), IPv4/IPv6 dual stack protocols, Path Maximum Transmission Unit (PMTU) Discovery, and Stateless Auto-configuration. The new HP-UX11i runs over Infiniband, FDDI, and Ethernet links.



The GR2000 carrier-class gigabit routers from Hitachi provide IPv6 at forwarding rates of a maximum of 26 Mpps and maximum line rates of 2.4 Gbps. The custom Application Specific Integrated Circuits (ASICs) of this system have a dual stack IPv4/IPv6 architecture and support packet filtering, IPv6 over IPv4 and IPv4 over IPv6 tunneling, and Stateless Auto-configuration among other IPv6 features.



Since the release of the IPv6-enabled AIX system in1997, IBM has shown support for IPv6 and has continually added IPv6 support to its products, such as DB2 for Windows v9.1, Unix, and Linux.



The IPv6 protocols for Linux are developed by a volunteer-run collaborative effort referred to as the Universal Playground for IPv6 (USAGI). This project was undertaken to remove the bugs in Linux implementations that made it difficult for a Linux-based system to conform to the IPv6 specifications.



Naturally, when all vendors are providing support for IPv6, Microsoft cannot be far behind. Most of the new versions of the Windows operating system, including Windows Vista, Windows Server Code, Windows Server 2003, and Windows CE .NET have built-in IPv6 enhancements and facilitate an orderly transition from IPv4 to IPv6.


Nortel Networks

Nortel Networks is working towards providing IPv6 support since the 1990s. The most recent generation of Nortels Ethernet Routing Switch 8600 offers wire speed and terabit performance. Nortel products also provide other IPv6 enhancements such as IPv6 Multicast, IPv4 to IPv6 Tunneling, Neighbor Discovery, and Stateless Auto-configuration.



The IP on NetWare that comes with NetWare 6.5 uses IPv6 as the native transport protocol on its server platform. The IPv6 features supported by Novell include Automatic and Configured tunneling, Basic Socket Interface Extensions, Neighbor Discovery, Stateless Address Auto-configuration, and Transmission Mechanisms for hosts and routers. Please note that with Novell, IPv6 works as an add-on component to the existing TCP/IP protocol stack.


Sun Microsystems

The Solaris 10 operating system by Sun Microsystems offers support for important IPv6 programming interfaces and specifications. It offers the advantage of Internet Key Exchange (IKE), which lets systems connect by using authentication and encryption, and integrated IP Security (IPsec). This vendor also facilitates dual stack tunneling, such as IPv6 over IPv4 and vice versa. For more details on the IPv6 support provided by a specific vendor, visit the IPv6 section on the vendor website or refer to system documentation specific to the vendor.

Cisco Takes Next Steps to Blend Wired, Wireless Networks

October 8 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Routers

Centralizing access control, security, management

Cisco revealed new WLAN access points and controllers, along with its latest steps to blend wireless and wired enterprise networks together.


The networking vendor announced upgraded server applications for access control, network management, and application management across both types of networks. Also new: virtualization options for these infrastructure products; two new lower-priced 802.11n access points for business networks; a new high-end WLAN controller, with a new high-availability feature for Wi-Fi clients.


The changes are part of a strategy that the vendor labels "Cisco Unified Access," now being formally announced though it's been featured on the company Website, and talked about with customers, for over a year. The basic idea, according to Cisco marketers, is to centralize and automate policy enforcement, security and authentication, and network management, regardless of how business end users connect to the company network, or with what kind of de-client device.


For access control functions, Cisco offers the Identity Services Engine (ISE), unveiled in 2011 as a central point to create and enforce a range of network policies based on the user's identity, role, and devices. [See our "First Look" slide on ISE]


A new update to the ISE software adds two features:

+ a Web-based portal, called My Devices," which lets end users register their personally owned devices with ISE, which in turn can enforce for these devices whatever bring-your-own-device (BYOD) policies have been set by the IT group


+ Secure Group Access, which lets a network administrator assign users to groups that have a set of pre-defined policies associated with them. New users automatically have these policies applied to them and their devices


For security and management across wired and wireless networks, Cisco offers Cisco Prime Infrastructure, also announced last year. It integrates several previously separate tools into one application with a single user interface, spanning both wired and wireless LANs.


That software, too, is being updated, adding what Cisco calls application visibility and control. Essentially, Prime can collect data from various sources and tools to create a visual picture of how specific applications are behaving, and of the end user's "network experience" in terms of delays or other quality standards.


Cisco also announced for small- and midsized WLANs, which several of these infrastructure products are now available as software that can be hosted on virtual servers: Cisco Prime Infrastructure and Cisco Identity Services Engine, along with Cisco Mobility Services Engine, and a WLAN controller that supports up to 200 access points.


The new WLAN hardware products are:

+ Cisco Aironet 2600 and 1600 Series access points, to complement the high-end 3600 Series: the two new products support 802.11n, but each in turn has fewer of the advanced features found in the flagship product. And unlike, the 2600, neither will be able to receive the 802.11ac plug-in module that Cisco recently announced it will ship in early 2013


+ Two new high-end WLAN controllers: the 8500 Series is aimed at service providers deploying Wi-Fi networks as adjuncts to wired or cellular network access, or at very large enterprise WLANs. The one-rack unit can manage up to 6,000 access points and 64,000 clients.


+ The new controller firmware release now supports what Cisco calls sub-second state-full switchover to improve WLAN availability. In effect, it's a way to shift Wi-Fi clients so quickly to a backup controller that they maintain their application sessions even if their original controller blows up.

Key Features & Benefits of Cisco 3750 Switches

Ease of Use: "Plug-and-Play" Configuration

A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the Cisco IOS Software revision running on the stack to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.

The Cisco 3750 Series stacks up to nine switches as a single logical unit for a total of 468 Ethernet or PoE 10/100 ports, or 468 Ethernet 10/100/1000 ports or PoE 10/100/1000 ports, or nine 10 Gigabit Ethernet ports.


Return on Investment through Lower Operations Costs

The automatic Cisco IOS Software version checking and loading of the global configuration parameters provide the first level of operational time saving. The second level is added during the event of an outage. When you remove a troubled switch from an existing stack of switches and replace it with another switch, the master switch will recognize this as a maintenance outage and automatically reload the port-level configuration that was on the previous switch without user intervention. This allows IT managers to have local personnel in remote locations perform maintenance tasks instead of sending costly technicians out for a few minutes of work, thus saving thousands of dollars in operational costs.


Mix-and-Match Switch Types: Pay as You Expand Your Network

Stacks can be created with any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E series. Customers who need a mixture of 10/100 and 10/100/1000 ports, PoE, and wiring-closet aggregation capability can incrementally develop the access environment, paying only for what they need. When uplink capacity needs to be increased, you can easily upgrade your bandwidth by adding a 10 Gigabit Ethernet version to the stack and upgrade your Gigabit Ethernet links with 10 Gigabit Ethernet on the existing fiber.


Availability: Uninterrupted Performance at Layer 2 and Layer 3

The Cisco Catalyst 3750 switch increases availability for stackable switches. Each switch can operate as both a master controller and a forwarding processor. Each switch in the stack can serve as a master, creating a 1:N availability scheme for network control. In the unlikely event of a single unit failure, all other units continue to forward traffic and maintain operation.


Smart Multicast: A New Level of Efficiency for Converged Networks

With Cisco StackWise technology, the Cisco Catalyst 3750 Series offers greater efficiency for multicast applications such as video. Each data packet is put onto the backplane only once, which provides more effective support for more data streams.


Superior Quality of Service Across the Stack and at Wire Speed

The Cisco 3750 Series offers Gigabit and 10 Gigabit Ethernet speed with intelligent services that keep everything flowing smoothly, even at 10 times the normal network speed. Mechanisms for marking, classification, and scheduling deliver best-in-class performance for data, voice, and video traffic, all at wire speed.


Network Security: Granular Control for the Access Environment

The Cisco 3750 supports a comprehensive set of security features for connectivity and access control, including ACLs, authentication, port-level security, and identity-based network services with 802.1x and extensions. This set of comprehensive features not only helps prevent external attacks, but also defends the network against "man-in-the-middle" attacks, a primary concern in today's business environment.


Single IP Management: Many Switches, One Address

Each Cisco Catalyst 3750 Series stack is managed as a single object and has a single IP address. Single IP management is supported for activities such as fault detection, VLAN creation and modification, network security, and QoS controls.


Jumbo Frames: Support for High-Demand Applications

The Cisco 3750 Series Switch supports jumbo frames on the 10/100/1000 configurations for advanced data and video applications requiring very large frames.


IPv6 Support

The Catalyst 3750 Series supports IPv6 routing in hardware for maximum performance. As network devices grow and the need for larger addressing and higher security becomes critical, the Cisco 3750 switch will be ready to meet the requirement.


Standard PoE Support: Graceful Addition of IP Communications

The Cisco Catalyst 3750 and 3750G PoE models support Cisco IP phones and Cisco Aironet wireless LAN (WLAN) access points, as well as any IEEE 802.3af-compliant end device. The Cisco Catalyst 3750 and 3750G 24-port versions can support 24 simultaneous full-powered PoE ports at 15.4W for maximum powered device support. The 48-port versions can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between.


10 Gigabit Ethernet Support: Increased Uplink Bandwidth for Gigabit Ethernet Deployments

The Cisco Catalyst 3750 allows network managers to incrementally add IEEE 802.3ae-compliant 10 Gigabit Ethernet connectivity in their wiring closets or grid clusters, further facilitating and enhancing Gigabit Ethernet networks. This provides investment protection to customers who want to use their existing fiber plant, add uplink bandwidth capacity to their switching stacks, and provide higher performance to applications and users.


Management Options

The Cisco 3750 Series switch offers both a superior command-line interface (CLI) for detailed configuration and Cisco Network Assistant Software, a Web-based tool for quick configuration based on preset templates. In addition, CiscoWorks supports the Cisco Catalyst 3750 Series for network wide management.
