Cisco 350X Series Stackable Managed Switches

Managed Switches That Provide the Ideal Combination of Features and Affordability

To stay ahead in a competitive marketplace, small businesses need to make every dollar count. That means getting the most value from your technology investments, but it also means making sure that employees have fast, reliable access to the business tools and information they need. Every minute an employee waits for an unresponsive application – and every minute your network is down – has an impact on your bottom line. The importance of maintaining a strong and dependable business network only grows as your business adds more employees, applications, and network complexity.

When your business needs advanced security and features but value is still a top consideration, you’re ready for the new generation of Cisco® Small Business managed switches: The Cisco 350X Series.

Cisco 350X Series Stackable Managed Switches

The Cisco® 350X Series Stackable Managed Switches (Figure 1) are a new line of stackable managed Ethernet switches that provide the rich capabilities you need to support a more demanding network environment at a very affordable price. The SG350X models provide 24 or 48 ports of Gigabit and Multigigabit Ethernet connectivity with 10 Gigabit uplinks. The Cisco 350XG models provide 12, 24, or 48 ports of all 10 Gigabit Ethernet, providing a solid foundation for your current business applications as well as those you are planning for the future. In addition, these switches are easy to deploy and manage without a large IT staff. The SG350X platforms are Cisco’s most costeffective platforms with 10 Gigabit Ethernet and stacking.

Figure 1. Cisco 350X Series Stackable Managed Switches

Cisco 350X Series switches are designed to protect your technology investment as your business grows. Unlike switches that claim to be stackable but have elements that are administered and troubleshot separately, the Cisco 350X Series provides true stacking capability, allowing you to configure, manage, and troubleshoot multiple physical switches as a single device and more easily expand your network.

A true stack delivers a unified data and control plane, in addition to management plane, providing flexibility, scalability, and ease of use because the stack of units operates as a single entity constituting all the ports of the stack members. The switches also protect your technology investment with an enhanced warranty, dedicated technical support, and the ability to upgrade equipment in the future. Overall, the Cisco 350X Series provides the ideal technology foundation for a growing business.

Features and Benefits

Cisco 350X Series switches provide the advanced feature set that growing businesses require and that highbandwidth applications and technologies demand. These switches can improve the availability of your critical applications, protect your business information, and optimize your network bandwidth to more effectively deliver information and support applications. The switches provide the following benefits.

High-Performance 10 Gigabit Ethernet

Cisco 350X Series switches break the barrier of 10 Gigabit Ethernet adoption by providing affordable and flexible configurations customized for the demanding network requirements of small and medium businesses.

With 10G copper ports on SG350XG switches, you can easily and cost-effectively enable 10G connections to servers and network storage devices with standard RJ45 Ethernet cable. You can also connect your SG350X access switches to the SG350XG aggregation with 10G SFP+ fiber connections, building a high-performance backbone to speed up the overall operation of your network.

Multigigabit Performance

Network needs are changing quickly. Thanks to evolving wireless standards and the rising number of wireless devices, keeping up with data rates and growing traffic can be a challenge. Your traditional Ethernet infrastructure can support speeds up to 1 Gigabit per second (Gbps), but competing today requires much more capacity. One option is completely replacing your older cabling infrastructure and upgrading your hardware. But wouldn’t it be

better to increase network speed and traffic capacity in a way that’s quick, inexpensive, and efficient? Cisco’s new Multigigabit Ethernet switches offer just that: an easy-to-deploy, budget-friendly solution that allows

you to increase network speed and bandwidth using your existing cables. By partnering with other industry leaders to form the NBASE-T Alliance, Cisco uses NBASE-T technology to help you get more out of your existing infrastructure. Save time and money by avoiding upgrades and extending the life of your installed cable plants. And discover the benefits of meeting consumer demand for increased bandwidth and speeds without a large initial investment.

Multigigabit Ethernet technology uses capabilities in your existing cabling infrastructure to meet bandwidth requirements and provide up to five times the performance. The technology enables intermediate data rates of 2.5 and 5 Gbps to ease the jump between traditional rates of 1 Gbps and 10 Gbps. These intermediate rates run on most installed cables and preserve older UTP wiring, which is good for 802.11ac wireless LAN applications.

The technology also supports Power over Ethernet (PoE) forms, including PoE+ and 60W PoE. Cisco Multigigabit Ethernet switches help you avoid having to run multiple cables between switches and access points and let your networks welcome next-generation traffic speeds and data rates.

Power over Ethernet Plus (PoE+) and 60W PoE

PoE capabilities simplify the deployment of advanced technologies by allowing you to connect and power network endpoints over a single Ethernet cable, without having to install separate power supplies. Cisco 350X Series switches are also fully backward compatible with Cisco legacy PoE protocols.

Cisco 350X Series switches support the Power over Ethernet Plus (PoE+) standard (IEEE 802. at), providing up to 30 watts per port. The switches also support 60W PoE on select ports to power compact switches, high-power wireless access points, or connected lighting. The PoE power is intelligently managed in a way such that only the amount of power needed by endpoints is delivered to it and not wasted. As a result, the switches can support devices that require more power, such as 802.11ac wireless access points, video-based IP phones, surveillance cameras, and more.

Multigigabit Performance

Network needs are changing quickly. Thanks to evolving wireless standards and the rising number of wireless devices, keeping up with data rates and growing traffic can be a challenge. Your traditional Ethernet infrastructure can support speeds up to 1 Gigabit per second (Gbps), but competing today requires much more capacity. One

option is completely replacing your older cabling infrastructure and upgrading your hardware. But wouldn’t it be

better to increase network speed and traffic capacity in a way that’s quick, inexpensive, and efficient? Cisco’s new Multigigabit Ethernet switches offer just that: an easy-to-deploy, budget-friendly solution that allows

you to increase network speed and bandwidth using your existing cables. By partnering with other industry leaders to form the NBASE-T Alliance, Cisco uses NBASE-T technology to help you get more out of your existing infrastructure. Save time and money by avoiding upgrades and extending the life of your installed cable plants. And discover the benefits of meeting consumer demand for increased bandwidth and speeds without a large initial investment.

Multigigabit Ethernet technology uses capabilities in your existing cabling infrastructure to meet bandwidth requirements and provide up to five times the performance. The technology enables intermediate data rates of 2.5 and 5 Gbps to ease the jump between traditional rates of 1 Gbps and 10 Gbps. These intermediate rates run on most installed cables and preserve older UTP wiring, which is good for 802.11ac wireless LAN applications.

The technology also supports Power over Ethernet (PoE) forms, including PoE+ and 60W PoE. Cisco Multigigabit Ethernet switches help you avoid having to run multiple cables between switches and access points and let your networks welcome next-generation traffic speeds and data rates.

High Reliability and Resiliency

In a growing business where availability 24 hours a day, 7 days a week is critical, you need to assure that employees can always access the data and resources they need. In these environments, stackable switches can play an important role in eliminating downtime and improving network resiliency. For example, if a switch within a Cisco 350X Series stack fails, another switch immediately takes over, keeping your network up and running. You can also replace individual devices in the stack without taking your network offline or affecting employee productivity.

The Cisco 350X Series also supports dual images, allowing you to perform software upgrades without having to take the network offline or worry about the network going down during the upgrade.

Simplified IT Operation

Cisco 350X Series switches help optimize your IT operations with built-in features that simplify and streamline dayto-day network operation:

●

True stacking allows you to troubleshoot, configure, and manage multiple physical switches as a single entity.

●

Cisco switches use common chipsets/software across all switching portfolios, so all Cisco switches within a category support the same feature set, making it easier to manage and support all switches across the network.

True Stacking

Some switches claim to support stacking but in practice support only “clustering,” meaning that each switch must

still be managed and configured individually. Cisco 350X Series switches provide true stacking capability, allowing you to configure, manage, and troubleshoot all switches in a stack as a single unit, with a single IP address, for up to 4 units and a maximum of 208 Ethernet ports.

A true stack delivers a unified data and control plane, in addition to management plane, providing flexibility, scalability, and ease of use because the stack of units operate as a single entity constituting all the ports of the stack members. This capability can radically reduce complexity in a growing network environment while improving the resiliency and availability of network applications. True stacking also provides other cost savings and administrative benefits through features such as cross-stack QoS, VLANs, LAGs, and port mirroring, which clustered switches can’t support.

Strong Security

Cisco 350X Series switches provide the advanced security features you need to protect your business data and keep unauthorized users off the network:

●

Embedded Secure Sockets Layer (SSL) encryption protects management data traveling to and from the switch.

●

Extensive Access Control Lists (ACLs) restrict sensitive portions of the network to keep out unauthorized users and guard against network attacks.

●

Guest VLANs let you provide Internet connectivity to nonemployee users while isolating critical business services from guest traffic.

●

Support for advanced network security applications such as IEEE 802.1X port security tightly limits access to specific segments of your network. Web-based authentication provides a consistent interface to authenticate all types of host devices and operating systems, without the complexity of deploying IEEE

802.1X clients on each endpoint.

●

Advanced defense mechanisms, including dynamic Address Resolution Protocol (ARP) inspection, IP Source Guard, and Dynamic Host Configuration Protocol (DHCP) snooping, detect and block deliberate network attacks. Combinations of these protocols are also referred to as IP-MAC port binding (IPMB).

●

IPv6 First Hop Security extends the advanced threat protection to IPv6. This comprehensive security suite includes ND inspection, RA guard, DHCPv6 guard, and neighbor binding integrity check, providing unparalleled protection against a vast range of address spoofing and man-in-the-middle attacks on IPv6 networks.

●

Time-based ACLs and port operation restrict access to the network during pre-designated times such as business hours.

●

Uniform MAC address-based security can be applied automatically to mobile users as they roam between wireless access points.

●

Secure Core Technology (SCT) helps ensure that the switch is able to process management traffic in the face of a Denial-of-Service (DoS) attack.

●

Private VLAN Edge (PVE) provides Layer 2 isolation between devices on the same VLAN.

●

Storm control can be applied to broadcast, multicast, and unknown unicast traffic.

●

Protection of management sessions occurs using RADIUS, TACACS+, and local database authentication as well as secure management sessions over SSL, SSH, and SNMPv3.

●

DoS attack prevention maximizes network uptime in the presence of an attack.

Networkwide Automatic Voice Deployment

Using a combination of Cisco Discovery Protocol, LLDP-MED, Auto Smartports, and Voice Services Discovery Protocol (or VSDP, a unique Cisco protocol), customers can deploy an end-to-end voice network dynamically. The switches in the network automatically converge around a single voice VLAN and QoS parameters and then propagate them out to the phones on the ports, where they are discovered. For example, automated voice VLAN capabilities let you plug any IP phone (including third-party phones) into your IP telephony network and receive an immediate dial tone. The switch automatically configures the device with the right VLAN and QoS parameters to prioritize voice traffic.

IPv6 Support

As the IP address scheme evolves to accommodate a growing number of network devices, the Cisco 350X Series can support the transition to the next generation of networking and operating systems such as Windows 7, Vista, and Linux. These switches continue to support previous-generation IPv4, allowing you to evolve to the new IPv6 standard at your own pace, and helping ensure that your current network will continue to support your business applications in the future. Cisco 350X Series switches have successfully completed rigorous IPv6 testing and have received the USGv6 and IPv6 Gold certification.

Advanced Layer 3 Traffic Management

The Cisco 350X Series enables a more advanced set of traffic management capabilities to help growing businesses organize their networks more effectively and efficiently. The switches provide static LAN Layer 3 routing, allowing you to segment your network into workgroups and communicate across VLANs without degrading application performance. With these capabilities, you can boost the efficiency of your network by offloading internal traffic-handling tasks from your router and allowing it to manage primarily external traffic and security. You can minimize the need to manually configure routing devices and simplify the ongoing operation of the network.

Power Efficiency

The Cisco 350X Series integrates a variety of power-saving features across all models, providing the industry’s most extensive energy-efficient switching portfolio. These switches are designed to conserve energy by optimizing power use, which helps protects the environment and reduce your energy costs. They provide an eco-friendly network solution without compromising performance. Cisco 350X Series switches feature:

●

Support for the Energy Efficient Ethernet (IEEE 802.3az) standard, which reduces energy consumption by monitoring the amount of traffic on an active link and putting the link into a sleep state during quiet periods

●

The latest Application-Specific Integrated Circuits (ASICs), which use low-power 65/40-nanometer technology and low-power, high-performance ARM CPUs

●

Automatic power shutoff on ports when a link is down

●

LEDs that can be turned off to save power

●

Embedded intelligence to adjust signal strength based on the length of the connecting cable

RMON

Embedded RMON software agent supports 4 RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis

IPv4 and IPv6 dual stack

Coexistence of both protocol stacks to ease migration

Firmware upgrade

●

Web browser upgrade (HTTP/HTTPS) and TFTP and SCP

●

Upgrade can be initiated through console port as well

●

Port mirroring

Traffic on a port or LAG can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to 8 source ports can be mirrored to one destination port

VLAN mirroring

Traffic from a VLAN can be mirrored to a port for analysis with a network analyzer or RMON probe. Up to 8 source VLANs can be mirrored to one destination port

Flow-based redirection and mirroring

Redirect or mirror traffic to a destination port or mirroring session based on flow

Remote Switch Port Analyzer (RSPAN)

Traffic can be mirrored across Layer 2 domain to a remote port on a different switch for easier troubleshooting

sFlow agent

Switch can export sFlow sample to external collectors. sFlow provides visibility into network traffic down to flow level

DHCP (options 12, 66, 67, 82, 129, and 150)

DHCP options facilitate tighter control from a central point (DHCP server), to obtain IP address, autoconfiguration (with configuration file download), DHCP Relay, and host name

Feature

Description

Autoconfiguration with Secure Copy (SCP) file download

Enables secure mass deployment with protection of sensitive data

Text-editable configs

Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment

Smartports

Simplified configuration of QoS and security capabilities

Auto Smartports

Automatically applies the intelligence delivered through the Smartports roles to the port based on the devices discovered over Cisco Discovery Protocol or LLDP-MED. This facilitates zero-touch deployments.

Secure Copy (SCP)

Securely transfer files to and from the switch

Textview CLI

Scriptable CLI. A full CLI as well as a menu CLI are supported

Cloud services

Support for Cisco Active Advisor

Localization

Localization of GUI and documentation into multiple languages

Login banner

Configurable multiple banners for web as well as CLI

Time-based port operation

Link up or down based on user-defined schedule (when the port is administratively up)

Time-based PoE

Capability for power to be on or off based on a user-defined schedule to save energy

Other management

Traceroute; single IP management; HTTP/HTTPS; SSH; RADIUS; port mirroring; TFTP upgrade; DHCP client; Simple Network Time Protocol (SNTP); Xmodem upgrade; cable diagnostics; Ping; syslog; Telnet client; SSH client; automatic time settings from Management Station

Green (power efficiency)

Energy detect

Automatically turns power off on RJ-45 port when detecting link down. Active mode is resumed without loss of any packets when the switch detects the link is up

Cable length detection

Adjusts the signal strength based on the cable length. Reduces the power consumption for shorter cables

EEE compliant (802.3az)

Supports IEEE 802.3az on all 10 Gigabit copper ports

Disable port LEDs

LEDs can be manually turned off to save on energy

General

Jumbo frames

Frame sizes up to 9K bytes. The default MTU is 2K

MAC table

64K addresses

Discovery

Bonjour

The switch advertises itself using the Bonjour protocol

LLDP (802.1ab) with LLDP-MED extensions

Link Layer Discovery Protocol (LLDP) allows the switch to advertise its identification, configuration, and capabilities to neighboring devices that store the data in a MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones

Cisco Discovery Protocol

The switch advertises itself using the Cisco Discovery Protocol. It also learns the connected device and its characteristics using Cisco Discovery Protocol

Product specifications

Power over Ethernet

The following switches support 802.3at PoE+, 802.3af PoE, and Cisco prestandard (legacy) PoE on any of the RJ45 network ports. 60W PoE is also supported on selected RJ-45 network ports

Maximum power of 60W is delivered to any of the 60W PoE ports, and maximum power of 30W is delivered to any of the other RJ45 network ports, until the PoE budget for the switch is reached
