Cisco’s New Nexus 400G Switches, More Bandwidth…

December 21 2018 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco & Cisco Network, #Cisco Switches - Cisco Firewall, #Data Center, #IT, #Networking, #Cisco Technology - IT News

Data center customers are facing 2 big challenges today.

  1. How can they support data-hungry apps like streaming video, or apps that use artificial intelligence and machine learning?
  2. And how can they keep growing their networks, without having to replace them every time? 

Now Cisco announces the new 400 Gigabit Ethernet (400G) switches that will give customers an edge to meet the need for bandwidth and scale.

The new 400G switches allow customers to create more powerful networks, more cost-effectively and in a fraction of the space.

They provide four times the bandwidth and four times the scale of existing switches without using four times the power.

And since the new switches are built on Cisco’s leading Nexus portfolio, customers can choose to deploy 400G in the way that best meets their needs.

They can be used on their own or in combination with Cisco’s leading security, automation, visibility and analytics software.

Cisco rolled out four models, two each in the Nexus 3400 and Nexus 9000 lines.

These next-generation 400G (Gigabit Ethernet) switches have four times more throughput than the networking giant’s current 100G offerings.

The two webscale 4300 switches are both built round the same single-chip 12.8Tbps ASIC, with a claim of 470ns latency. The 3432D-S packs 32 400Gbps ports into one rack unit (RU), while the 3408-S takes up four rack units to give a more flexible package to mix and match with lower speed ports.

The enterprise switches are slower, with a 6.4Tbps fabric and, as with the webscale products, there are two models: the Nexus 93600CD-GX, 1RU switch with 16 400Gbps ports, and the 9315D-GX, also a 1RU switch, but with 32 ports to allow lower capacity links to be included.

  1. Cisco’s two new Nexus 3400-S switches for hyperscale companies will be available for customer evaluations in December.
  2. The two new Nexus 9300-GX switches for large enterprises and service providers will be available for customer evaluations during the first quarter of 2019.

New Catalyst Products-Catalyst 9200 switches & Cisco Catalyst 9800 Series Wireless Controller

November 27 2018 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco & Cisco Network, #Cisco Wireless - Cisco Wireless AP, #Networking, #Cisco Switches - Cisco Firewall

Cisco announced two big additions to its Catalyst 9000 family: the Catalyst 9200 switch and the Catalyst 9800 wireless LAN controller.

The Cisco Catalyst 9000 Series was built from the ground up for intent-based networking. It runs on a single, open, programmable OS that powers all access and WAN products. This allows Cisco customers to turn on new software innovations faster, simplify IT operations, and lower costs.

A single software controller automates the entire network, while programmable ASICs provide unmatched investment protection. And security is embedded into the network, instead of bolted on. 

By extending the Catalyst 9000 Family to wireless deployments and mid-market customers, Cisco is bringing the new era of networking to even more customers. New products include:

  • New Wireless Controller: For the first time, customers can run consistent security, automation and analytics services across wired and wireless environments by leveraging the same OS. The Cisco Catalyst 9800 Series Wireless Controller can be run anywhere—on premise, in any cloud, or embedded virtually on Catalyst 9000 switches. It supports today’s wireless standards and is ready for the 802.11ax standard. It also elevates wireless services with software updates without disruption, new threat defense and advanced programmability.
  • Two models are available:
  • Catalyst 9800-40--scales up to 2,000 APs, 32,000 clients and offers 40 Gbps throughput
  • Catalyst 9800-80--scales up to 6,000 APs, 64,000 clients and offers 80 Gbps throughput
  • New Mid-Market Switch: The Catalyst 9200 switches extend intent-based networking to simple branch deployments and mid-market customers. For the first time, the mid-market gets access to the full suite of enterprise services, all at a similar price point as the previous generation of Cisco switches. Simplicity without compromise. And with the security and resiliency customers have come to expect from the Catalyst family.
  • Up to 48 ports of full Power over Ethernet Plus (PoE+) capability
  • Resiliency with Field-Replaceable Units (FRU) and redundant power supply, fans, and modular uplinks
  • flexible downlink options with data or PoE+
  • Operational efficiency with optional backplane stacking, supporting stacking bandwidth up to 160 Gbps
  • UADP 2.0 Mini with integrated CPU offers customers optimized scale with better cost structure
  • Enhanced security with AES-128 MACsec encryption, policy-based segmentation, and trustworthy systems
  • Layer 3 capabilities, including OSPF, EIGRP, ISIS, RIP, and routed access
  • Advanced network monitoring using Full Flexible NetFlow
  • Cisco Software-Defined Access (SD-Access): Simplified operations and deployment with policy-based automation from edge to cloud managed with Cisco Identity Services Engine (ISE); Network assurance and improved resolution time through Cisco DNA Center

The new switches use Cisco's own ASIC and run the same OS that powers all of the company's access and WAN products.

Availability, Services and Support

  • The Catalyst 9800 Wireless Controllers will be available in Q4CY18
  • The Catalyst 9200L switches will be available in Q4CY18, with the Catalyst 9200 switches available in Q1CY19
  • Cisco and its partners offer a full lifecycle of services to help customers streamline the journey to truly intent-based networks.

Q. Does mixed stacking require any configuration on Cisco Catalyst 2960-X Series Switches?

A. Yes. The switch stack speed should be set to 40 using configure mode command “switch stack-speed 40” on Cisco Catalyst 2960-X switches to stack with Cisco Catalyst 2960-S switches. While forming a homogenous stack of Cisco Catalyst 2960-X revert back the stack speed to 80 using “no switch stack-speed 40”.

Q. Can Cisco Catalyst 2960-X and 2960-XR Series Switches stack together?

A. No. Cisco Catalyst 2960-X and 2960-XR Series Switches can’t be stacked together. Even though they belong to the same 2960-X Series, they do not share same Cisco IOS license models.

Q. What are the possible mixed-stack combinations?

A. The LAN Base models can only form mixed stacks. The possible mixed-stack combinations are listed in Table2.

Q. Which SDM template should be selected on the Cisco Catalyst 2960-X Series with LAN Base to form a mixed stack with Cisco Catalyst 2960-S?

A. If Cisco Catalyst 2960-S is running the “default” SDM template, then Cisco Catalyst 2960-X must use the “default” template. If Cisco Catalyst 2960-S is running the “lanbase-routing” template, then Cisco Catalyst 2960-X must use the same.

Q. Can Cisco Catalyst 2960-S be the stack master in a mixed stack of 2960-S and 2960-X switches?

A. Yes. Cisco Catalyst 2960-S can be stack master in a mixed stack.

Q. In a mixed stack of Cisco Catalyst 2960-S and 2960-X, must all the switches be on the same Cisco IOS Software release?

A. Yes. All the switches in the stack, regardless of model, must be on the same Cisco IOS Software release. This includes the rebuild number. The minimum Cisco IOS Software release that will support both 2960-S and 2960-X is 15.0(2)EX.

Q. Can we use FlexStack stacking modules with Cisco Catalyst 2960-X Series?

A. No. The form factors of FlexStack-Plus and FlexStack modules are different. The FlexStack stacking module cannot be used with the Cisco Catalyst 2960-X Series. Similarly, the FlexStack-Plus module cannot be used with the Cisco Catalyst 2960-S Series.

Catalyst 9000 Switches, New Speeds Transitions in Enterprise

May 17 2018 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Switches - Cisco Firewall, #Cisco & Cisco Network, #Data Center

Catalyst 9000 Switches Enabling Higher Speeds in Enterprise with Investment Protection

Cisco Catalyst 9000 fixed and modular, core and access LAN switches have been designed for an entirely new era of networking. Now your network can learn, adapt, and evolve.

An intuitive network recognizes your intent, mitigates threats through segmentation and encryption, and learns and changes over time. It's simple. You can unlock opportunities, enhance security, improve business agility, and dramatically increase operational efficiencies.

Get unmatched scale for perpetual Cisco UPOE/POE+/PoE with our Catalyst 9000 switches. They're a critical part of an integrated security architecture--one that works before, during, and after a threat occurs to reduce attack surface, detect malware and threats, and rapidly contain those threats. Catalyst 9000 switches are flexible in scale and port speed, from 1 Gigabit Ethernet to multigigabit (1,2.5,5,10 Gbps), 25 GE, 40 GE, and 100 GE.​​​​

New Speeds Transitions in Enterprise

40GE has gained momentum as a potential migration option for aggregation layer upgrades requiring scale beyond 10GE.

40GE is a great option for green-field deployments, but suffers from some challenges for brown-field environments. 40GE optics use QSFP+ form factor that require expensive adapters for backward compatibility with existing 10G SFP+ optics. Moreover, in deployments that use multimode fiber, 40GE can be quite restrictive since it supports only one-third the reach as that of 10GE based deployments.

25GE is a good alternative that provides a seamless migration path from 10GE with better price-to-value, avoiding cable upgrade expenses, and reducing total cost of ownership (TCO).

Emergence of SFP28 has changed the network speed upgrade path from 10GE->40GE to 10GE->25GE->100GE.

SFP28 based 25GE optics use the same form factor as SFP+, while providing 2.5 times the bandwidth. Dell’Oro predicts that that Ethernet industry will be heading to 25GE/100GE technologies instead of 40GE; and 25GE is expected to outgrow 10GE by 2021.

One of the main drivers for this phenomenon is availability of new optics with SFP28 technology that offers a better cost curve along with longer reach capabilities suitable for Campus deployments. Enterprises can significantly reduce the number of cables, power, and device footprint with SFP28 technology in aggregation layer. Considering the compelling economics of 25GE, core layer with 100GE in a three-tier architecture is a no brainer! Using four lanes of 25GE, 100GE backbone platforms require lesser cabling relative and thus benefit from reduced space requirements and cost savings. Further, 4x25GE breakout cable support provides Enterprises additional options for conveniently migrating to an extensible 100GE network with investment protection.

Cisco leading the industry with 25GE Enterprise optimized Optics

Progressive Enterprises that start evaluating options to embrace these new speeds face some key questions – how to maintain same supported distances as 10GE (300m/400m), how to stage seamless network upgrades, will cost/performance justify new investments? Designed to overcome the challenges of 40GE, Cisco’s SFP28 portfolio offers customers a wide variety of high-density and low-power options addressing these considerations.

Some of the key benefits include:

  • Longer Reach Cisco’s innovations, SFP10/25-CSR, to support high-density multi-rate optics enables Enterprises to drive up to 300m/400m over standard dual strand OM3/OM4 fiber.
  • Ease of Adoption–Cisco’s dual rate optics, SFP10/25G-CSR for multi-mode fiber and SFP10/25G-LR for single-mode fiber provide seamless migration path with un-surpassed investment protection.
  • Better Price-to-Performance–Cisco’s single laser low cost optics consume less power and provide higher density relative to quad laser based 40GE optics, thus resulting in OpEx savings from power and cooling and lower TCO.

Along with introduction of new optics, Cisco has continued to innovate with new generation of programmable ASIC that enables network upgrades to 25GE and 100GE in Enterprise possible now

April 28 2018 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Switches - Cisco Firewall, #IT, #Cisco Technology - IT News, #Cisco & Cisco Network, #NGFW

Cisco ASA 5506-X, ASA 5506W-X, and ASA 5506H-X Hardware Installation Guide

How to maintain and upgrade your ASA firewalls, such as the popular ASA 5506-X, ASA 5506W-X and ASA 5506H-X? In this article we will share the two guides for Cisco ASA 5506-X, ASA 5506W-X and ASA 5506H-X, which contain the following sections:

  • Connect the DC Adapter for the 5506H-X
  • Install the Adjustable Power Supply Retainer

How to Connect the DC Adapter for the ASA 5506H-X?

You can order an optional DC power supply that supplies 24V DC (part number PWR2-20W-24VDC) or 20W 20-60V DC (part number PWR2-22W-20-60VDC).

Warning:

1. This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than 36 VDC, 5A. Statement 1005

2. This product requires short-circuit (overcurrent) protection to be provided as part of the building installation. Install only in accordance with national and local wiring regulations.

3. The device is designed to work with TN power systems.

To connect the DC power on your 5506H-X, follow these steps:

Step1: Connect the black and white lead wires to a 12 VDC source. The black lead is negative or ground and the white lead is positive. The output cable is 1.3 meters and the input cable is 1 meter in length.

5 Benefits You Get When Buying a Top of Rack Switch Nexus 3100V:

  1. 100G uplinks: Cisco predicts that global data center IP traffic will grow 31% every year in the next 5 years. For this, it is obvious that 100G is the new norm for higher bandwidth, big data, and IP storage workloads.
  2. 16 MB enhanced buffers: Compared to 12MB buffer from previous generation, the Nexus 3100V models offer 16 MB enhanced buffers to absorb bursts of traffic and applications. You won’t have to worry when you need to expand your network in the future, because these deep buffers are designed for highly oversubscribed environments.
  3. 16 GB Increased system memory: In the previous model – Cisco Nexus 3100XL – Cisco already increased the system memory from 4GB to 8GB in order to introduce network programmability features developed in NXOS 7.x. But as networks are becoming more complex, competitive businesses need more memory to store more objects. Hence, Cisco has doubled the capacity again in the Nexus 3100V models from 8GB to 16GB to improve capacity for object-model programming.
  1. Quadrupled ingress ACL table size to 16,000: for more greater securitytraffic control, enhanced security, and policy management flexibility
  1. Support full VxLAN routing (layer 3 VxLAN): With this, workloads in different segment IDs can directly communicate, whereas with VxLAN bridging (layer 2 VxLAN), workloads need to be in the same segment ID to interact.

Cisco continues to bring you true flexibility and scalability through rich architectural options for any size of data center to address increasing business requirements. You can never go wrong with more connectivity options and a diverse set of form factors to meet ever-changing data center needs.
