What to look for when buying a networking switch?

If you’re in the market for a Cisco Catalyst switch, there are a few things you’ll want to keep in mind. Here are some of the most important factors to consider:

1. Port count and speed: Depending on your needs, you’ll want to make sure the switch has enough ports and that they’re effecient enough to support your network traffic.

2. Management and security features: Cisco Catalyst switches come with a variety of management and security features that can help ensure your network’s safety and efficiency. Be sure to evaluate which features are most important to you and make sure the switch you select offers them.

3. Budget: Of course, the cost is always a factor when making any purchase. Be sure to set a budget for yourself and stick to it when choosing a Cisco Catalyst switch.

Do you need a networking switch?

If you have a small business with a limited number of devices that need to connect to a network, you may not need a networking switch. A router may be all you need to create a LAN (Local Area Network). However, if you have more than a few devices that need to connect, or if you require high-speed connectivity for some devices, then you will likely need a switch. Switches allow you to expand your network by providing additional Ethernet ports. They also provide better performance than routers because they can process data faster and they operate at full-duplex mode, meaning they can send and receive data simultaneously.

Cisco Nexus 3000 Switch: An Overview

The Cisco Nexus 3000 series is a high-speed, high-density, 1, 10, 25, 40, or 100 Gigabit Ethernet switch designed for data center aggregation. The large buffers and routing table sizes of the Cisco Nexus C36180YC-R also make this switch an alternative for a wide range of applications, such as IP storage, Demilitarized Zone (DMZ), big data, and edge routing. The switch comes in a compact 1-Rack-Unit (1RU) form factor and provides extensive Layer 2 and Layer 3 functions. It is part of the R-Series family and runs the industry-leading NX-OS operating system software.

The comprehensive programmability features enable organizations to run today’s applications while also preparing them for demanding and changing application needs. The Cisco Nexus C36180YC-R supports both forward and reverse (port-side exhaust and port-side intake) airflow schemes with AC and DC power inputs.

The Cisco Nexus C36180YC-R is a Small Form-Factor Pluggable (SFP) and Quad SFP (QSFP) switch with 48 SFP and 6 QSFP28 ports. Each SFP port can operate at 1, 10, or 25 Gigabit Ethernet and each QSFP28 can operate at 100 or 40 Gigabit Ethernet or in a breakout cable configuration[1]. 6 QSFP28 ports can supports the IEEE 802.1ae MAC Security (MACSec) standard.

Cisco Nexus 3000 Switch: Highlights

The Cisco Nexus 3000 series provides the following:

●     Wire-rate Layer 2 and 3 switching on all ports, with up to 3.6 Terabits per second (Tbps) and up to 1.67 billion packets per second (bpps)

●     Programmability, with support for Cisco® NX-API, Linux containers, Extensible Markup Language (XML), and JavaScript Object Notation (JSON) Application Programming Interfaces (APIs), the OpenStack plug-in, Python, and Puppet and Chef configuration and automation tools

●     High performance and scalability with a 6-core CPU, 32 GB of DRAM, and 8 GB of dynamic buffer allocation, making the switch excellent for massively scalable data centers and big data applications

●     Flexibility:

◦    Both fiber and copper cabling solutions are available for 1-, 10-, 25-, 40-, 50-, and 100-Gbps connectivity, including Active Optical Cable (AOC) and Direct-Attached Cable (DAC)

◦    The QSFP28 ports can be configured to work as 4 x 25-Gbps or 4 x 10-Gbps ports

●     High availability:

◦    Virtual PortChannel (vPC) technology provides Layer 2 multipathing by eliminating the Spanning Tree Protocol. It also enables fully used bisectional bandwidth and simplified Layer 2 logical topologies without the need to change the existing management and deployment models

◦    Advanced maintenance capabilities include hot and cold patching and Graceful Insertion and Removal (GIR) mode

◦    The switch uses hot-swappable Power-Supply Units (PSUs) and fans

●     NX-OS operating system with comprehensive, proven innovations:

◦    Power-On Auto Provisioning (POAP) enables touchless bootup and configuration of the switch, drastically reducing provisioning time

◦    Cisco Embedded Event Manager (EEM) and Python scripting enable automation and remote operations in the data center

◦    Ethanalyzer is a built-in packet analyzer for monitoring and troubleshooting control-plane traffic and is based on the popular Wireshark open-source network protocol analyzer

◦    Complete Layer 3 unicast and multicast routing protocol suites are supported, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), Routing Information Protocol Version 2 (RIPv2), Protocol Independent Multicast Sparse Mode (PIM-SM), Source-Specific Multicast (SSM), and Multicast Source Discovery Protocol (MSDP)

FeatureBenefit
Software compatibility: NX-OS interoperates with Cisco products running any variant of Cisco IOS Software and also with any networking OS that conforms to the networking standards listed as supported in this data sheet.●  Transparent operation with existing network infrastructure ●  Open standards ●  No compatibility concerns
Modular software design: NX-OS is designed to support distributed multithreaded processing. Its modular processes are instantiated on demand, each in a separate protected memory space. Thus, processes are started and system resources allocated only when a feature is enabled. A real-time preemptive scheduler that helps ensure timely processing of critical functions governs the modular processes.●  Robust software ●  Fault tolerance ●  Increased scalability ●  Increased network availability
Troubleshooting and diagnostics: NX-OS is built with innovative serviceability functions to enable network operators to take early action based on network trends and events, enhancing network planning and improving Network-Operations-Center (NOC) and vendor response times.●  Quick problem isolation and resolution ●  Continuous system monitoring and proactive notifications ●  Improved productivity of operations teams
Ease of management: NX-OS provides a programmatic XML interface based on the NETCONF industry standard. The NX-OS XML interface provides a consistent API for devices. NX-OS also supports Simple Network Management Protocol (SNMP) Versions 1, 2, and 3 MIBs. In addition, NX-API and Linux Bash are now supported.●  Rapid development and creation of tools for enhanced management ●  Comprehensive SNMP MIB support for efficient remote monitoring
Role-Based Access Control (RBAC): With RBAC, NX-OS enables administrators to limit access to switch operations by assigning roles to users. Administrators can customize access and restrict it to the users who require it.●  Tight access control mechanism based on user roles ●  Improved network device security ●  Reduction in network problems arising from human errors
