Build a reliable, easy-to-use business network at an affordable price
In today's hyper-connected world, reliable access to network resources is critical to all businesses. However,
you also need to invest wisely to stay competitive, knowing how to separate the essential from the extraneous
and get the most value for your dollar. For investment in network infrastructure, building a solid foundation for
your business is essential, but it doesn’t mean you need the most advanced feature set on the market.
For businesses requiring high performance, advanced security, and rich manageability from the network, fully
managed switches are an excellent choice. However, they also typically come with high price tags. Smart
switches provide the right level of network features and capabilities for growing businesses at a lower price, so
you’ll have more dollars to put toward other areas of your business.
With Cisco® 250 Series Smart Switches (Figure 1), you can achieve business-class network performance and
security without paying for advanced network features that you will not use. When you need a reliable solution
to share online resources and connect computers, phones, and wireless access points, but low cost is a top
priority, Cisco 250 Series Smart Switches provide the ideal solution.
Figure 1.

Features and benefits
Cisco 250 Series Smart Switches provide all of the features you need to create a basic business-class network
at an affordable price. These features include:
●
Easy configuration and management: Cisco 250 Series switches are designed to be easy to deploy
and use by small businesses or the partners that serve them:
◦ Smart Network Application (SNA) is an innovative network-level monitoring and management tool
embedded in the Cisco 100 to 500 Series switches. It can discover network topology, display link
status, monitor events, apply configurations, and upgrade software images across multiple switches
in the network.
◦ The FindIT Network Manager and Probe are designed to manage Cisco 100 to 500 Series switches,
routers, and wireless access points. They let you proactively manage the network instead of just
reacting to events. Cisco 250 Series switches support the embedded FindIT Network Probe,
eliminating the need to set up a separate hardware or virtual machine on site. For more information,
visit https://www.cisco.com/c/en/us/products/cloud-systems-management/findit-network-
management/index.html.
◦ The FindIT Network Discovery Utility works through a simple toolbar on the user’s web browser to
discover Cisco devices on the network and display basic device information, inventory, and new
firmware updates to aid in the configuration and speed the deployment of Cisco Small Business
products. For more information, visit https://www.cisco.com/c/en/us/products/cloud-systems-
management/small-business-findit-network-discovery-utility/index.html.
◦ Simple or advanced-mode graphic user interfaces reduce the time required to deploy, troubleshoot,
and manage the network. Configuration wizards simplify the most common configuration tasks and
provide the ultimate tool for anyone to set up and manage the network.
◦ Cisco Smartports technology provides more advanced capabilities and hands-on control by
automatically configuring ports with specific levels of security, QoS, and availability according to the
type of connected device, based on Cisco best practices and pretested configurations. The Auto
Smartports feature automatically applies the intelligence delivered through the Smartports roles to the
port based on the device types discovered over Cisco Discovery Protocol or LLDP-MED. This
capability facilitates zero-touch deployments.
◦ The USB port on the front panel of the switch enables easy image and configuration transfer for faster
deployment or upgrades.

Reliability and performance: Cisco 250 Series switches have been tested to deliver the high
performance and reliability you would expect from a Cisco switch and help you prevent costly downtime.
The switches speed file transfer times, improve slow and sluggish networks, keep your vital business
applications available, and help your employees respond more quickly to customers and each other.
With a network based on Cisco 250 Series switches, you can address all of your business
communications and connectivity needs and reduce the total cost of ownership of your technology
infrastructure. Cisco 250 Series switches also support 10 Gigabit Ethernet uplinks on select models, so
you can build a high-performance and future-ready network to support your thriving business.
●
Layer 3 static routing: This capability allows you to segment your network into separate workgroups and
communicate across VLANs without degrading application performance. As a result, you can manage
internal routing with your switches and dedicate your router to external traffic and security, helping your
network run more efficiently.
●
Power over Ethernet Plus (PoE+): Cisco 250 Series switches are available with PoE+ on both Fast
Ethernet and Gigabit Ethernet models. This capability simplifies the deployment of IP telephony, wireless,
video surveillance, and other solutions by allowing you to send data and power to network endpoints
over the single network cable, eliminating the need for separate power supplies or outlets. PoE+
provides up to 30W of power per port, enabling deployments for 802.11ac wireless access points, PanTilt-Zoom (PTZ) IP cameras, videophones, and thin client devices, delivering more flexibility and
investment protection.
●
PoE powered device and PoE pass-through: The 10-port compact models of Cisco 250 Series can
work as PoE powered devices and draw power from upstream PoE switches in the wiring closet,
simplifying the deployment in meeting rooms, classrooms, hotel rooms, and other flexible locations. Each
switch can accept up to 60W of power per uplink port to power itself and pass through the power to the
downstream PoE end devices if needed.
●
Network security: Cisco 250 Series switches provide the security and network management features
you need to maintain a high level of security for your business, keep unauthorized users off the network,
and protect your business data. The switches include integrated network security to reduce the risk of a
security breach, with IEEE 802.1X port security to control access to your network, Denial-of-Service
(DoS) attack prevention to increase network uptime during an attack, and extensive Access Control Lists
(ACLs) to protect sensitive portions of the network from unauthorized users and guard against network
attacks.
●
IPv6 support: As the IP network addressing scheme evolves to accommodate more devices, you can
have peace of mind that your network is ready. Cisco 250 Series switches provide native support for
IPv6 alongside traditional IPv4. With USGv6 and IPv6 Gold Logo certifications, the 250 Series will enable
you to take full advantage of IPv6-enabled operating systems and applications in the future, without
having to upgrade your network equipment.
●
IP telephony support: Cisco 250 Series switches include QoS features to prioritize delay-sensitive
services such as voice and video, simplify unified communications deployments, and help ensure
consistent network performance for all services.

●
Networkwide automatic voice deployment: Using a combination of Cisco Discovery Protocol, LLDPMED, Auto Smartports, and Voice Services Discovery Protocol (VSDP, a unique, patented Cisco
protocol), customers can deploy an end-to-end voice network dynamically. The switches in the network
automatically converge into a single voice VLAN and set of 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.
●
An energy-efficient solution: Cisco 250 Series switches are designed to be energy efficient and eco
friendly without compromising performance. They help conserve energy by optimizing power use, which
helps protect the environment and lowers your energy costs. Power-saving features include:
◦ 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
◦ Automatic power shutoff on ports when a link is down
◦ Embedded intelligence to adjust power based on cable length
◦ Fanless design in most models, which reduces power consumption, increases reliability, and provides
quieter operation
◦ Ability to turn off LEDs to conserve power
