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 3800 AP and Multigigabit Ethernet (mGig)

August 30 2018 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Technology - IT News, #IT, #Cisco Wireless - Cisco Wireless AP

Multigigabit Ethernet (mGig), N-BASET and 802.11bz are all methods by which faster speeds can be realized (faster than 1G) using existing infrastructure wiring such as CAT-5e. The goal is to deliver up to 5 times the speed in the Enterprise without replacing existing cable structure.

Note: Although the AP 2800 does not directly support mGig, these are ideal switches for providing the power required by the AP 2800 as well.


Here are the recommended mGig switches and PoE solutions for the AP 3800.

Figure1. Cisco line of mGig capable switches

Ideally a switch supporting IEEE 802.3bz (mGig, which is also referred to as N-BASET) will deliver the fastest Ethernet using older cable systems such as CAT-5 and deliver +30W for newer PoE devices.

Figure2. Cisco Multigigabit enables speeds over 1G on conventional CAT5e cable systems

In regards to cabling structure and Cisco Multigigabit Ethernet:

  1. Data rates up to 1G requires 62.5–MHz bandwidth (Cat 5e is 100 MHz)
  2. Data rates up to 2.5G requires 100MHz bandwidth (Cat 5e is 100 MHz)
  3. Data rates up to 5G requires 200MHz bandwidth, which is more than the specified Cat 5e 100MHz bandwidth, but within the Cat 6 cable

The main point is that 5G operations over Cat 5e may have issues using certain cable configurations due to the fact we are using Cat 5e cable beyond the specification.

Figure3. Cisco Multigigabit cable support at rates up to 5G

 *Watch for cross-talk issues in bundles or when cables are in same pipe. Keep lengths of CAT-5e between 30-50m or below when using dense cable bundles; for example, cables in a dense area like a pipe or places where five or more cables are tied in a bundle.

Comparison of FlexStack, FlexStack-Plus, and FlexStack-Extended

June 27 2018 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Technology - IT News, #Cisco Switches - Cisco Firewall, #Cisco Modules - Cisco Cables - Cisco Memory, #Technology

Cisco 2960-X Series support FlexStack-Plus and FlexStack-Extended technologies. What are these two stacking solutions that are supported by Catalyst 2960-X Series? And what are differences between them? The following part will list the main features and differences of FlexStack, FlexStack-Plus, and FlexStack-Extended.

Cisco FlexStack-Plus is a hot-swappable, modular stacking solution that provides a true stacking capability, with all switches acting as a single switching unit with a unified data plane, using a single IP address. Cisco FlexStack-Plus is supported by the Cisco Catalyst 2960-X Series and allows the stacking of up to eight switches, with a throughput of 80 gigabits per second.

Cisco FlexStack-Extended enables long-distance out-of-the-wiring-closet stacking. FlexStack-Extended allows back-panel stacking of up to eight Cisco Catalyst 2960-X or 2960-XR Series Switches. FlexStack-Extended can be added to the Cisco Catalyst 2960-X or 2960-XR Series with a back stacking slot. 

FlexStack-Extended is available in two module configurations: Fiber module (C2960X-FIBER-STK) and Hybrid module (C2960X-HYBRID-STK).

And the FlexStack-Plus and FlexStack-Extended technologies are similar to FlexStack technology with the differences listed in the Table below.

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.

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
