Critical Building Block for Any Small Office Network

To stay ahead in a competitive marketplace, 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 effect on your profits. 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 networking features and security for your digital transformation yet value
is still a top consideration, you’re ready for the new generation of managed switches: the Cisco® Business 350
Series Switches (Figure 1).

●

Support for Simple Network Management Protocol (SNMP) allows you to set up and manage your
switches and other Cisco devices remotely from a network management station, improving IT workflow
and mass configurations.

High Reliability and Resiliency

In a growing business where availability 24 hours a day, 7 days a week is critical, you need to ensure business
continuity and that employees can always access the data and resources they need. The Cisco Business 350
Series Switches support 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.

Strong Security

Cisco Business 350 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.

●

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.

●

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.

Power over Ethernet

Cisco Business 350 Series Switches are available with up to 48 Power over Ethernet (PoE) ports. This capability
simplifies advanced technology deployments such as IP telephony, wireless, and IP surveillance by allowing you
to connect and power network endpoints over a single Ethernet cable. With no need to install separate power
supplies for IP phones or wireless access points, you can take advantage of advanced communications
technologies more quickly and at a lower cost. Models support 802.3af PoE and 802.3at PoE+.

Networkwide Automatic Voice Deployment

Using a combination of Cisco Discovery Protocol, Link Layer Discovery Protocol-Media Endpoint
Discovery (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 Virtual Local Area Network (VLAN) and Quality of Service (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.
