Migration from 40Gb to 100Gb

October 9 2018 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco & Cisco Network, #IT, #Cisco Technology - IT News, #Cisco Transceiver Modules

The popular QSFP+ 40Gb bi-directional (BiDi) transceiver enabled data center operators to upgrade from 10Gb to 40Gb without the need to replace fiber cable infrastructure.

The next generation dual-rate BiDi, which has both 40Gb and 100Gb operational modes, offers the same benefits and more.

The Cisco QSFP 40/100 Gb dual-rate BiDi transceiver can function as a 40Gb BiDi, matching its reach of 100m and 150m over OM3 and OM4 multi-mode fiber, respectively.

In 100Gb mode, the dual-rate BiDi’s reach is 70m and 100m on OM3 and OM4, respectively. In both modes, the BiDi reach matches its SR4 counterpart.

As a single transceiver with these two modes of operation, the Cisco dual-rate BiDi enables data center operators to re-use their existing duplex LC-connectorized MMF infrastructure for migration from 10 Gb to either 40 Gb or 100 Gb Ethernet connectivity, or migration from 40Gb to 100Gb. Figure2 shows the 100G BiDi Transceivers deployed in a leaf-spine logical architecture.

Features

• 40Gb and 100Gb dual-rate capability

• Backward compatibility with 40Gb QSFP+ BiDi

• QSFP28 form factor

• Operates over duplex LC-connectorized MMF fiber infrastructure, same as 10Gb SR and 40Gb BiDi

• Onboard forward error correction

• PAM4 optical modulation

• Bi-directional optical technology

• Enables incremental upgrade to 100Gb from 10Gb SR or 40Gb BiDi

Backward compatible with Cisco’s 40Gb BiDi technology

Only Cisco offers backward compatibility with native 40Gb BiDi transceivers in a QSFP28 form factor. Like the native 40Gb BiDi, the dual-rate 40/100 Gb BiDi transmits bi-directionally on both fibers, using nominal wavelengths of 850nm and 910nm and passive wavelength division multiplexing (WDM) filters at either end to isolate Tx and Rx channels. In 40Gb mode, it transmits and receives 20Gb NRZ channels on each fiber, for a total aggregate bandwidth of 40Gb.

In 100Gb mode, it operates 50Gb PAM4 channels, for a total aggregate bandwidth of 100Gb. PAM4 technology enables 50Gb data rate with signaling at 25Gbaud rates. The 40/100G BiDi contains a gearbox to translate the signal from a 4x25G format, native to the QSFP28 form factor, to the 2x50Gb format for the optical domain. It also employs onboard forward-error-correction (FEC) to reduce bit error rate. This makes it possible to use current generation transmitter and receiver technology.

The dual-rate 40/100 Gb BiDi offers multiple migration options to Cisco customers who are currently operating either 10Gb or 40Gb links in their data center architectures. By upgrading network equipment one end at a time, operators can exercise flexibility in schedules and budgets. Figure 3 shows combinations of port and BiDi transceiver types.

Cisco ONE Software Device Tiering Guide-Part 1

May 24 2018 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #IT, #Cisco Technology - IT News, #Cisco & Cisco Network, #Cisco Routers, #Data Center, #Cisco Wireless - Cisco Wireless AP

We know that Cisco ONE Software suites have been introduced to provide a cost-effective and flexible way for customers to acquire software for their data center, WAN, switching, and wireless needs. Do you know how to choose the Cisco ONE Software License for your Cisco hardware? In the following part it shows you the Cisco ONE Software Device Tiering Guide that tells you more…

As described in the FAQ for Cisco ONE Software License Portability, the hardware product series and/or tier on which you have deployed your licenses determines your portability options. Licenses are portable within a product tier (for example, Cisco 2900 Series Integrated Services Routers (ISR) to 2900 Series ISR).

Devices with greater capabilities are categorized in a higher tier because they gain more benefit from the capabilities in Cisco ONE Software. You can port your licenses to a higher tier, but an upgrade fee may be involved.

Table1 describes the different equipment refresh scenarios. Subsequent tables describe the tiers for each family of hardware.

Table1. License portability use cases

Use Case

Policy

Cost

Refresh a device with a device in the same tier.

Example: Cisco 2901 ISR to 2911 ISR

If a Cisco Software Support Services (SWSS) contract is in place, the software can be used on the new device.

None.

Refresh a device with a device in a higher tier.

Example: Cisco 2901 ISR to 3925 ISR

You must pay a software upgrade fee to use the software from the original device on the replacement device.

 

You must purchase an upgraded Cisco SWSS contract for the new software. You receive a credit for the old support contract.

The cost is the license cost on the new device minus the license cost on the old device, at current list prices, subject to customer-negotiated discounts.

 

You also need to consider the cost of the upgraded Cisco SWSS contract.

Refresh a device with a device in a lower tier.

Example: Cisco 3925 ISR to 2901 ISR

You are entitled to use the software deployed on your original device on a lower tier replacement device. You retain license portability rights associated with the original device family, so you can subsequently refresh the device back to the original device family.

 

You can opt to downgrade the license permanently to the lower tier device family, which would allow you to renew your Cisco SWSS contract at a lower price. In that case, the license entitlement is set permanently to the lower-tier family.

None. The support contract remains with the original device family.

 

 

 

If you permanently downgrade, you may renew your Cisco SWSS contract at a lower price.

Refresh a device with a next‑generation device.

Example: Cisco 3925 ISR to 4000 Series ISR

In this case, the transfer depends on whether the next-generation Cisco 4000 Series ISR is considered the same tier as the existing device, or a higher or lower tier. Depending on the tier, the policies outlined above apply.

 

In all cases, you must migrate your software licenses to a next-generation device before your older device reaches end of support. At this stage, your Cisco SWSS contact will have expired and you will not meet the portability criteria.

The tier of the next-generation device determines the cost. Depending on the tier, the policies outlined above apply.

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

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

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.

Figure1. DC Power Adapter 

1

Black wire (negative)

2

White wire (positive)

3

Adapter

  

Step2: Plug the adapter cord into the ASA.

Note: The power adapters have 18 AWG wires for the input connection. Tinned bare wires are used for the input connection because there is no standard established for connector type. Screw terminal blocks are most often used.

Step3: Power on the ASA and check that it has power. See LEDs for information on the power LED.

How to Install the Adjustable Power Supply Retainer?

You can install an adjustable power supply retainer for the Delta and LiteOn power supplies in the rack-mount tray. The bracket kit contains the bracket, 2 M3 screws, and washers. The following figure shows the adjustable retainer.

Figure2. ASA Bracket Assembly 

1

Two screws to loosen to change from high to low bracket

2

Two captive screws to attach to rack-mount tray

Step1: Slide the rack-mount shelf containing the ASA(s) out of the rack.

Step2At the back of the rack-mount shelf behind the power supplies, install the adjustable retainer.

  1. Loosen the 2 top screws (item 1 in the figure above) slightly to adjust the bracket for each power supply.

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.

NOTE: To manage the Nexus 5500 and Nexus 5600, two types of licenses are needed: the DCNM LAN and DCNM SAN. Each is a separate license.

More Notes:

Nexus switches have a grace period, which is the amount of time the features in a license package can continue functioning without a license.

Enabling a licensed feature that does not have a license key starts a counter on the grace period. You then have 120 days to install the appropriate license keys, disable the use of that feature, or disable the grace period feature.

If at the end of the 120-day grace period the device does not have a valid license key for the feature, the Cisco NX-OS software automatically disables the feature and removes the configuration from the device. There is also an evaluation license, which is a temporary license. Evaluation licenses are time bound (valid for a specified number of days) and are tied to a host ID (device serial number).
