Cisco 3650 Vs. 3850 Catalyst Switches

Cisco Catalyst 3650 and 3850 series switches are enterprise class stackable switches. Cisco Catalyst 3650 series was unveiled in 2013 which designed to converge wired and wireless networking. Just in the same year, Cisco launched its first flagship Catalyst 3850 series switches . That provide a converged wired and wireless platform as well. With they have many things in common, many people confused about them and found it hard to decide which one to buy. This article would introduce Cisco 3650 and 3850 series switch as well as their main differences.

Cisco Catalyst 3650 Series Switch

There are 21 Cisco 3650 Series Switch models in total. All Cisco Catalyst 3650 Series Switches have fixed, built-in uplink ports. The Catalyst 3650 features line rate 24 and 48 Gigabit Ethernet ports and an integrated wireless controller. It can be stacked in groups of nine switches for support of up to 25 access points and 1,000 clients at 40Gbps. The uplink ports of all switch models can be divided into the following five types:

  • Four Gigabit Ethernet with Small Form-Factor Pluggable (SFP)
  • Two 10 Gigabit Ethernet with SFP+ and two 10 Gigabit Ethernet with SFP or four Gigabit Ethernet with SFP
  • Four 10 Gigabit Ethernet with SFP+ or four Gigabit Ethernet with SFP
  • Eight 10 Gigabit Ethernet with SFP+ or eight Gigabit Ethernet with SFP
  • Two 40 Gigabit Ethernet with QSFP+

  • High compatibility. The 3850 switches support a variety of optical modules and connectors, therefore allowing many deployment options.
  • Enhanced security. It comes with native TrustSec functionality such as Security Group Tag (SGT) so that you have it enabled everywhere—from access to aggregation. Also, fiber connections provide strong physical security.
Differences
—Flexibility

The flexibility of the 3850s is greater than the 3650s, because they are stacking and optional stacking switches respectively. The 3850s can do power stacking, that is an exclusive feature compared to the 3650s. Stacking is built in, and the short stacking cables are included. Larger stacks might require the longer stacking cables, that is a potential downside.

3650s can do stacking as well, but you need to buy the modules separately (and they are like $1,000 a pop list price), which adds up quickly.

—Power

The 3850s is the more powerful device than the 3650s, which featured as the great horsepower. Besides, as we mentioned before, the 3850s can do power stacking while the 3650s cannot.

—Capacity

Compared with the 3650s series switches, the 3850s series switches have higher capacity. The maximum switching capacity of the 3850s switches can arrive at 1280 Gbps on 48-port 10 Gigabit Ethernet SFP+ model while the 3650s switches at 472 Gbps on 48-port Multigigabit models.

All About Cat7

Network has become an indispensable part of our daily life. Many homes and businesses today deploy network with either a wired network connection or a wireless connection, and these two network connection methods have their own advantages: wired connection is typically faster than wireless connection and has lower latency; while wireless connection makes it easier to get access to the network from nearly any convenient location. As network technology has kept stepping forward, these two types of network hardware also continue to advance, satisfying the requirements of users. Take wired connection for example, now a newer cable category is Cat7 ethernet cable. This article will focus on Cat7 and share the advantages and disadvantages of Cat7 cabling.

Overview of Cat7

Cat7 ethernet cable is not currently recognized by TIA/EIA, but it is designed to support 10G Ethernet with distance up to 100 meters. It can offer transmission frequencies of up to 600 MHz, which is 6 times larger than Cat5e and 2.4 times larger than Cat6. The Cat7 ethernet cable contains four twisted copper wire pairs, just like the earlier standards, and shielding has been added for individual wire pairs and the cable as a whole. In addition, Cat7 ethernet cable is terminated with GG45 (GigaGate45) connector, which is still compatible cat5e cable and cat6 cable with RJ45 connector.

Cat7 ethernet cable

Advantages And Disadvantages of Cat7 Cabling

Though Cat7 ethernet cable is a newer cable category, it is not the best choice for all network deployment. Why? Keeping reading and you will find the answer in the following part.

Advantages
  • Cat7 has higher bandwidth of up to 600 MHz, which is 6 times larger than Cat5e (100 MHz) and 2.4 times larger than Cat6 (250 MHz).
  • Cat 7 has an overall shield as well as individual shielding of every pair. It performs better to protect against outside interference. Therefore, it is suitable for installing in strong RFI & EMI environment.
  • Cat7 is thicker, more bulky, and more difficult to bend.
  • Cat7 is regarded as the most durable cable and has a longer lifespan of fifteen years than cat5e cable and cat6 cable.
  • Cat7 is compatible with preceding Ethernet cable standards like Cat5e and Cat6. as a result, users can move Cat5e cable or Cat6 cable from existing copper based LAN and install Cat7 without having to change the existing electronics.
Disadvantages
  • Cat7 ethernet cable is not currently recognized by TIA/EIA. It is not a solid, established industry standard.
  • Cat7 is very heavy. Individual pair and overall shielding increases the overall weight and size of Cat7, which makes it not an job for Cat7 cabling. Larger & stronger pathway and more stringent bend radius (100 mm or 4 inch) are required.
  • Cat7 is more expensive. Individual pair and overall shielding also means higher labor costs and more work towards cable termination.
  • Cat7 cabling may cause ground loop problems. If both ends of the cable are connected to ground, it will lead to ground loops which are a major cause of noise, hum, and interference in audio, video, and computer systems. They can also create an electric shock hazard, since ostensibly “grounded” parts of the equipment, which are often accessible to users, are not at ground potential.
Conclusion

For home network deployment, it is not a great option, because it is more expensive and Cat7 cabling is complicated. However, Cat7 is suitable for the place where needs high speed data transmission and is high EMI environment. Therefore, in order to get a successful network deployment, you have to make a careful plan, be familiar with environment, confirm the requirement of network deployment and choose the right transmission media. FS.COM offers the best and most versatile copper cables including Cat5e, Cat6 and Cat7 products. For more details, please visit our site.

White Box Switch: to Be or Not to Be

Current Situation

White box switch refers to the ability to use “generic”, white box switching and routing hardware in the forwarding plane of a software-defined network (SDN). So that consumer can purchase a generic Ethernet switch without a network operating system (NOS), and install an operating system of their choice. However, white box switch hasn’t been widely accepted and recognized currently. The reasons are as followed: 1. No matter in a data center or enterprise, switch accounts for a very low share in network construction, far below the server, storage, and bandwidth. But it takes up a very important spot in an enterprise, and any problem of it would result in widespread influence. 2. In terms of customer technicians, few people are knowledgeable about network. So when they have problems with network equipment, they are prone to turn to vendor service. While unfortunately, white box switch manufacturers are not professional enough, especially those manufacturers having separated software and hardware, which means white box manufacturers can’t take on projects like branded manufacturers. 3. White box manufacturers have little proficiency. They don’t have complete product lines, and they don’t make core equipment, let alone functionally complex provider equipment (PE).

white box switch

Production Mode

Generally, there are four major components that make up a network switch, namely silicon, box, network OS and drivers, and applications. White box switching is the idea that the silicon & box can be bought as one thing, and the network OS and applications as other things. This idea is opposite to the traditional norm of network switch acquisition. Through the separation of software and hardware, customers can obtain different support levels for hardware and software. Having a software platform that is independent of hardware also allows support engineers to debug it easily and provide relevant output to the networking team.

Advantages

Although status quo of white box switch is not so satisfactory, it won’t block and cloud its prospect of development since it still has a lot of advantages overweighing its disadvantages.

1. Cost

To be honest, most vertically integrated switching & routing platforms are loaded with features the most of consumers will never use. Furthermore, many of the features that consumers want to use come at a high price. So they often have to pay extra expenses for these features. However, the overall cost of white box switch is lower than those branded equipment, because it removed some features that consumers rarely used and brand premium as well.

2. Quality & Simplification

Despite this price advantage, some consumers would regard white box as cheap inferior goods, which turns out a misunderstanding. Because the companies making hardware are professional OEM factories. Their quality of switches is as good as branded switches. Even the brands of hardware are their OEM. That is to say, white box is on par with brand-name systems because they are actually the same hardware. Apart from the quality, white box switch does not involve complicated function, and they only make function sets needed by target consumers. For example, they are less likely to involve MPLS VPN, ISSU Etc. Instead, they focus on relatively simple and controllable data center, especially SDN switch. It simplifies software and makes it understood to most users.

3. Features & Capabilities

White boxes typically are used as a top-of-rack switch or as part of an SDN deployment. They support industry standards such as OpenFlow. Besides, they are highly programmable and work with orchestration tools such as Ansible, Chef and Puppet. Also, white box switches are characterized by strong telemetry capabilities and openness so that network administrators can get whatever information they need for whatever purpose. In fact, in this area, it’s fair to say white boxes are often superior to traditional layer 2/3 switches.

Prospect of White Box Switch

White box switch puts new ground rules in the market, and lowers the cost of acquisition, while at the same time allows consumers to pick and choose the features and functions they are willing to pay for. As the white box switching and NOS market begin to broaden, I believe what the market will see is a broad variety of applications that consumers can choose to add to their newly flexible networks. White box switch is not merely about choosing a hardware manufacturer or NOS provider. The path white box switch ultimately takes us down to is choice of applications running on those switches. That’s a whole different market. That’s a whole different way to think about networking.
