More fast questions and answers help you learn more about the new Catalyst 9000 Series.

Cisco Catalyst 9000 network features and services (common to all Cisco Catalyst 9000 Switches)

Q: What feature sets do the Cisco Catalyst 9000 Switches support?

A: The Cisco Catalyst 9000 Series Switches support the packaging of features into Essentials and Advantage packages. The details of the features in each package are listed in the data sheets–link provided below in the Pricing and Ordering section.

Q: What programmability capabilities are available on the Cisco Catalyst 9000?

A: The Cisco Catalyst 9000 opens a completely new paradigm in network configuration, operation, and monitoring through network automation. The Cisco automation solution is open, standards-based, and extensible across the entire network lifecycle of a network device.

• Device provisioning: Through Plug-and-Play (PnP), Zero-Touch Provisioning (ZTP), and Preboot Execution (PXE)

• Configuration: Model-driven operation through open Application Programming Interfaces (APIs) over NETCONF, Python Scripting

• Customization and monitoring: Streaming telemetry

• Upgrade and manageability: In-Service Software Upgrade (ISSU), patchability, and config/replace

Q: What management capabilities are available for the Cisco Catalyst 9000?

A: You can manage it using the Cisco IOS Software Command-Line Interface (CLI), using Cisco Prime® Infrastructure 3.1.7 DP13, Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM), onboard Cisco IOS XE Software Web User Interface (WebUI), Simple Network Management Protocol (SNMP), or Netconf/YANG.

Q: Is there an onboard web GUI on the Cisco Catalyst 9000?

A: Yes. An onboard web GUI is available.

Q: What is the purpose of the blue beacon LED on the Cisco Catalyst 9000?

A: The blue beacon LED is common across the Cisco Catalyst 9000 Series Switches to simplify the operations. It makes chassis identification easier when several such switches are mounted on racks. A remote administrator can enable the LED to blink to help the local operator quickly locate the chassis. The local operator presses the mode button to acknowledge.

Q: What is the maximum number of VRF instances that I can configure on a Cisco Catalyst 9000?

A: The maximum number of VRFs that you can configure on a Cisco Catalyst 9000 is 256.

Q: What is Cisco’s direction for wireless?

A: Cisco believes that the best solution for a wired or wireless network is achieved when integrated into SD-Access, Cisco’s lead architecture for the next-generation enterprise network. This solution delivers consistency with wired infrastructure around policy, segmentation, orchestration and automation, and assurance. This new architecture delivers the best experience for mobility, guest, IoT, multicast services, and overall network performance with its distributed data plane and centralized control-plane architecture.

Q: What wireless support is provided with the Cisco Catalyst 9000 platforms?

A: Cisco Catalyst 9000 products are instrumental in supporting the following wireless capabilities in the SD-Access architecture:

• Connect access points and integrate them into the SD-Access fabric. The switch integrates with the fabric control plane (LISP), thereby providing reachability for the access points and clients in the fabric.

• Deliver macro (VRF) and micro (Scalable Group Tag (SGT) [SGT] group-based) segmentation to the access points to deliver end-to-end policies.

• Can terminate guest VXLAN traffic, so there is no need for a dedicated guest anchor controller.

The support for wireless capability at launch will be together with the AireOS 8.5 Controller running on an Cisco 8540 Wireless Controller, Cisco 5520 Wireless Controller, or Cisco 3504 Wireless Controller appliance with the Cisco Catalyst platforms functioning as Fabric Edge and Fabric Border nodes.

 

Q: What are the SD-Access wireless capabilities?

A: The new Cisco Catalyst 9000 Series switches provide a complete solution for Campus with Cisco AireOS Conrollers and Wave 2 access points.

Q: What are the advantages of integrating wireless in the SD-Access fabric architecture?

A: • Highest performance and scale: Distributed data-plane forwarding in hardware distributed in the network paired with the large control-plane scale offered by the dedicated controller appliances.

• Best guest: You don’t need a dedicated guest anchor controller in the Demilitarized Zone (DMZ): Traffic is sent directly to the fabric border to exit the fabric. Also, there is no sub-optimal traffic forwarding such as from an access point to a foreign controller and on to a guest anchor controller.

• Best mobility: IP addressing is simpler; there is one subnet for the entire wireless SSID across the network, and no hairpin of traffic when roams occur.

• Simple operation: Operation is simple because wired and wireless are treated the same and operated together; they have common policies and controller-based automation.

• Wired innovations applied to wireless: First-hop security innovations available for wired can also be applied to wireless; for example, Dynamic ARP Inspection (DAI), IP Source Guard (IPSG), and DHCP Snooping.

• Segmentation across wired and wireless:

-The virtual network now passes all the way to wired as well as wireless devices.

-This segmentation is important for separation of certain devices from others, such as IoT and building automation devices connected over wireless.

-It is also important for security reasons to reduce attack the surface; if someone gets into a segment, the person can move only within that segment.

-Because segmentation is handled by the fabric, the number of SSIDs can be limited.

• Best multicast:

-The solution offers the best performance of distributed replication in hardware across the network.

These switches truly deliver the best of wired and wireless together.

What Changes We can Expect from Cisco in 2017

June 13 2017 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco News, #IT, #Data Center, #Technology, #Cisco Technology - IT News

For all kinds of customers, what can they expect from Cisco in 2017? In the following article, Zeus Kerravala (the founder and principal analyst with ZK Research, and provides a mix of tactical advice to help his clients in the current business climate.) listed the main points that users and clients expect from Cisco in 2017.

  • Cisco will take a chunk of the security market. The security market is easily the most fragmented of all of the IT submarkets. It’s currently a $75 billion market, with no single vendor having anywhere close to double-digit share. Cisco, in particular, has fumbled around in security for years with different initiatives and architectures that have been ineffective.

    Times are different today. As I pointed out in an earlier post, Cisco has never been positioned better in the security industry, and the company is finally using its greatest asset—its dominance in the network—to create tangible differentiation. Look for 2017 to be the year it breaks away from the competition and takes a chunk of the security share.
  • Cisco breaks away in collaboration. Collaboration at Cisco has had its ups and downs over the past few years, but the company now pointed in the right direction. Spark was launched as a Slack-like team collaboration tool, but in actuality, it’s much more than that. It’s a fully integrated cloud, hardware and software experience that can deliver seamless, easy-to-use experiences on a mobile phone, desktop or meeting room. Expect Cisco to continue to innovate around Spark and create its next wave of growth in collaboration.
  • The data center gets a shot in the arm with an acquisition. The Unified Computing System (UCS) carried the data center business unit at Cisco for years. Recently, though, the growth of the product has slowed. In fact, this past quarter saw the data center revenue fall 3 percent.

    UCS is a great product, but the compute industry is shifting to hyperconverged infrastructure (HCI). Cisco’s current offering, HyperFlex, is an OEM from SpringPath, and channel feedback has been that they would prefer Cisco to own the product rather than OEM it. The OEM allows Cisco to dip its toe in the water, and in 2017 Cisco will jump in with both feet by acquiring SpringPath, which will stimulate data center growth.
  • Expect Cisco to focus on analytics. When one thinks of analytics, the name Cisco is rarely top of mind. However, analytics is becoming a core component of Cisco’s strategy. Not only is it at the core of the recently announced Tetration product, but it is also fundamental to the company’s differentiation in security, Internet of Things, network operations and collaboration. Expect to see Cisco do more analytics on more network data to differentiate its offering from the many smaller competitors that can’t match its footprint.
  • Cisco will push its engineer base to learn new skills. Markets transition. That’s a fact. And when then do, the engineers who work with the technology need to change their skills. Most vendors don’t see the transition, won’t admit its happening or don’t want to upset their engineer base by forcing them to change. And that always ends up being a disaster.

    Think of engineers who worked with mainframes, Token Ring, TDM voice, SNA and other trends. Most are gone, as are the vendors that sold the stuff.

    One of Cisco’s competitive advantages is its huge base of engineers, many of whom are steeped in the way networking was done. Based on my discussions with Cisco executives, including Jeanne Dunn, who runs Cisco’s learning group, I believe Cisco wants to disrupt its engineer base and have them learn new skills—such as automation, data sciences, programming and business skills. Some won’t like the changes to the certification requirements, but the fact is Cisco engineers need to start developing skills for the digital era.
  • Executive churn will slow down. Since Robbins took the helm, there has been a steady churn at the executive level, including Kelly Ahuja, Rob Soderberry and the famed “MPLS” group—just to name a few.

    I believe Robbins’ team is set now. And while there might be the odd departure here and there, this is the team he’s going to run with.

    One question I’ve been asked is if the company would replace the recently departed CTO Zorawar Biri Singh. I believe engineering is in the best hands they can be under the co-leadership of Rowan Trollope (IoT and applications) and David Goeckeler (networking and security), and the structure will stay as is. Get used to the faces at the top; they should be sticking around for a while.

One thing that will remain the same at Cisco is the company’s commitment to changing the world. Cisco’s former CEO, John Chambers, had a great desire to have Cisco make the world a better place. As I pointed out earlier this year, Robbins has picked up the Corporate Social Responsibility (CSR) ball and is running with it faster than ever.

The world is becoming increasingly digitized, and many of the digital enablers—such as IoT, cloud and mobility—are network centric. The coming year presents Cisco a great opportunity to flex its enormous networking muscles and move into the next wave of growth.

Cisco ASR 1000 Series Use Cases

March 21 2017 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Routers, #Technology, #Cisco Technology - IT News

When your enterprises or organization are going to choose the Cisco ASR 1000 Series, you should know these Cisco ASR 1000 Series Enterprise and Service Provider Applications.

Cisco ASR 1000 Series routers sit at the edge of your enterprise data center or large office connecting to the WAN, as well as in service provider points of presence (POPs). The Cisco ASR 1000 Series will benefit the following types of customers:

  • Enterprises experiencing explosive network traffic as mobility, cloud networking, and video and collaboration usage increase: Cisco ASRs consolidate these various traffic streams and apply traffic management and redundancy properties to them to maintain consistent performance among enterprise sites and cloud locations.
  • Network service providers needing to deliver high-performance services, such as DCI and branch-office server aggregation, to business customers: Service providers can also use the multiservice routers to deploy hosted and managed services to business and multimedia services to residential customers.
  • Existing Cisco 7200 Series Router (end-of-sale) customers looking for simple migration to a new multiservice platform that delivers greater performance with the same design.

Tables2 and Table3 describe enterprise and service provider application examples, respectively.

Table2. Cisco ASR 1000 Series Enterprise Applications

Deployment Scenario

Description

System Characteristics

WAN edge: Guarantee high-priority applications by creating a virtual “glass ceiling” for lower-priority applications. Improve user experiences.

● Applies Modular QoS CLI (MQC) policies on VLANs or tunnels

● Limits an arbitrary collection of low‑priority traffic to a certain bandwidth

● Classifies based on differentiated services code point (DSCP), Network-Based Application Recognition (NBAR), and Cisco IOS Cisco IOS FPM (FPM) into numerous hierarchies, one for high priority and one for low priority

● Implements flexible hierarchies

● Supports 464,000 queues

● Allows all queues to have a minimum, maximum, and excess bandwidth with priority propagation

Multiservice, scalable, and secure headend:

IP Security (IPsec) VPN aggregation scales to meet the new bandwidth demands of service provider IP VPNs.

● Reduces capital expenditures (CapEx) and operating expenses (OpEx) by migrating and consolidating to fewer Cisco ASR 1000 Series Routers

● Protects investment through easy transition to much higher encryption support, offering encryption support of up to 78 Gbps with the 200-Gbps Cisco ASR 1000 Series ESP (ASR1000-ESP200)

● Offers easier management through embedded security services in the Cisco Flow Processor, with no additional service modules or blades required

● Optimized for QoS and IP Multicast applications

● Supports thousands of sites

● Supports 8,000 IPsec tunnels

● Offers up to 78-Gbps encryption performance and up to 200-Gbps noncryptographic throughput support with the Cisco ASR 1000 Series 200-Gbps Embedded Services Processor
(ASR1000-ESP200) engine

Embedded high-speed firewall:

With the Zone-Based Policy Firewall, the Cisco ASR 1000 Series acts as an implicit and complete barrier between any interfaces not members of the same zone. An explicit zone-pair policy must be specified (using Cisco Policy Language; that is, MQC) in each direction between each zone pair. The policy establishes within the router the kind of stateful inspection (Layer 4, Layer 7, or application) and session parameters to apply to each zone pairing.

Example: An explicit policy allowing HTTP and Domain Name System (DNS) to traverse the Internet-demilitarized zone (DMZ) zone boundary would be required.

● The firewall is embedded in the Cisco Flow Processor; no additional service blades or modules are required.

● Multiple gigabits of bandwidth are routed while at the same time the router performs Zone‑Based Policy Firewall and other baseline features such as QoS, IPv4, IPv6, NetFlow, and others.

● The Cisco ASR 1000 Series provides logging of all firewall session states off to network management applications capable of accepting relatively huge amounts of flow data. Third-party applications can handle the session data.

● Provides firewall performance of 2.5 to 200 Gbps, depending on the ESP used

● Offers high-speed logging of 40,000 sessions per second with NetFlow Version 9

Managed CPE: This implementation of branch-office architecture offers powerful investment protection with services and scale.

● Managed customer premises equipment (CPE) helps branch offices route correctly over various types of Ethernet to comply with service-level agreements (SLAs).

● This application encrypts multiple gigabits of bandwidth without any additional service blades or modules.

● Managed CPE optimizes the WAN to route around brownouts in the service provider network to further guarantee mission-critical applications.

● This application offers small form factors (1 rack unit [1RU] for the Cisco ASR 1001-X and ASR 1001-HX and 2RUs for the Cisco ASR 1002-HX and ASR 1002-X Routers), including software modularity and ISSU.

Note: ISSU is not supported on Cisco ASR 1001-X, ASR 1001-HX, ASR 1002-HX, ASR 1002-X, or ASR 1004. Managed CPE offers accessibility even when the Cisco IOS Software is down.

● Offers first-in-industry software redundancy support, without any additional hardware module, on Cisco ASR 1001-X, ASR 1001-HX, ASR 1002-HX, ASR 1002-X, and ASR 1004; hardware redundancy and ISSU are supported on the Cisco ASR 1006 and ASR 1013.

● Offers powerful firewall and NAT performance of 2.5 to 200 Gbps and 1.8- to 78-Gbps encryption support in addition to WAN optimization and voice features

 

Table3. Cisco ASR 1000 Series Service Provider Applications

Deployment Scenario

Description

System Characteristics

Broadband L2TP Access Concentrator (LAC) or L2TP Network Server (LNS):

The solution offers Layer 2 Tunneling Protocol (L2TP) endpoint-to-tunnel
Point-to-Point Protocol (PPPoX) or IP sessions with bandwidth demands in the STM-1 ATM, Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet range.

● The application is ideal for triple-play (data, voice, and video) wholesale deployments.

● It offers integral service delivery.

● Per-user firewall, session border controller (SBC), etc. are supported.

● Provides very high scalability of up to 64,000 subscribers and up to 16,000 tunnels

Service provider edge: Layer 3 VPN (L3VPN) provider edge:

Example: You can deploy the solution at the distributed provider edge or provider edge in global VPN networks for bandwidth demands such as asymmetric DSL (ADSL), T1/E1, STM-1, STM-4, Fast Ethernet, Gigabit Ethernet, etc.

● The application provides integral services in the Cisco Flow Processor.

● It provides encryption, FPM, NBAR, SBC, IP Multicast, etc.

● Offers excellent multicast performance

● Scales to 8,000 Virtual Route Forwarding (VRF) instances, 1 million Label Distribution Protocol (LDP) labels, and 4,000 access control lists (ACLs)

● Supports up to 4 million IPv4 routes

● Supports up to 4 million IPv6 routes

Service provider edge: High-end route reflector:

You can use the solution as a route reflector for bandwidth support of 40 Gbps.

● The application provides high scalability.

● It offers a modular design of the route processor and ESP with hardware and software redundancy.

● Scales up to 29 million IPv4 routes

● Supports 64,000 Layer 3 adjacencies

Next-generation voice and multimedia example: Cisco Unified Border Element Enterprise Edition (ENT Edition):

The SBC application (named Cisco Unified Border Element [ENT Edition]) performs the voice and video gateway functions simultaneously with regular IP data services. No appliance or additional service blade is required. The control protocols and media protocols work transparently within a complex voice architecture. For more information, refer to the CUBE data sheet at http://www.cisco.com/go/cube.

● Secure and authenticated Session Initiation Protocol (SIP) trunk connections enable service providers to offer real-time voice and video services.

● The WAN edge is simpler to manage because there is only one egress and one ingress point for access to Internet or service provider services.

● The control plane is separated from the data-forwarding plane, so the signaling and control processes are separate from media processing.

● The CUBE SBC application can be used for SIP trunk video and/or audio services provided by service providers or for Internet-accessible SIP line-side services to Cisco Unified Communications Manager.

● Facilitates SBC with security, QoS, IPv4, and IPv6 (IP Unicast and IP Multicast simultaneously)

● Supports 16,000 simultaneous voice calls and multimedia data of up to 200 Gbps with accounting, firewall, and call quality enabled

● Integrated with inbox high-availability infrastructure and Dynamic Host Configuration Protocol (DHCP) Relay

LiFi vs. WiFi-Basic Difference between LiFi and WiFi

February 8 2017 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Technology - IT News

In the last article, we told what Li-Fi is and what LiFi system basics are. It seems a cool technology in network communication? Compared to today’s popular Wi-Fi, can you tell some difference between them? In this article we list some main differences between LiFi and WiFi. Which one is better? Let’s check.

We know that Li-Fi is the short form of Light Fidelity and Wi-Fi is the short form of Wireless Fidelity. LiFi uses light for data transmission while WiFi uses electro-magnetic waves at radio frequencies for data transmission. Due to less interference incurred by light compare to radio frequency waves, it is used in more dense environments.

LiFi covers distance of about 10 meters while WiFi covers about 30 meters. Both provides almost same data transfer rate. Let us understand Li-Fi internet and Wi-Fi internet network architectures.

Figure-1: Li-Fi internet

The figure-1 depicts Li-Fi internet network architecture. As shown in the figure there are two major components in Li-Fi internet viz. LED Lamp and Li-Fi Dongle.

• As shown lamp driver is connected with internet on one end and with LED lamps on the other end. Streaming content from internet are pushed to the LED lamps through Lamp driver software.

• LED lamps are placed at different locations as per requirement in the office or home premises for multiple users.

• Li-Fi dongle is used in order to use Li-Fi internet services by various users. As shown Person#1 is browsing internet in Laptop, Person#2 in tablet and Person#3 in smartphone.

• As shown LiFi dongle is composed of photodetector, amplification & processing and applications for different types of data.

• All the LED lamps can be swithed on and off using a power button switch provided.

• Li-Fi internet provides very fast data rate at 1 Gbps speed.

Figure-2: Wi-Fi internet

 

• The figure-2 depicts Wi-Fi internet network architecture.

• As shown in the figure there are two major components in WiFi internet viz. WiFi router and WiFi dongle or WiFi Stations.

• WiFi router is connected with ADSL modem or Cable modem. This modem is connected with network of internet service provider.

• WiFi router works on multiple bands (e.g. 2.4 or 4.9 or 5 GHz) as per requirement. It converts internet data packets into wifi compliant signals at above bands. WiFi works on IEEE 802.11 standards.

• These EM waves are received by WiFi dongles or Stations connected with IP compliant devices. Hence WiFi internet is used by various clients as shown in the figure-2.

In the following table we will list the basic difference between LiFi and WiFi technologies.

Feature Comparison: LiFi vs. WiFi

Lifi is not the replacement of wifi technology. It can be considered as incredible companion of the wifi technology. It operates between 380 nm to 780 nm optical range. LiFi is used to exchange data incredibly rapidly and securely at much lower power level compare to WiFi.

Products Based on Li-Fi Technology | Li-Fi products
