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:
? Simple and 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.
? The USB port on the front panel of the switch enables easy image and
configuration transfer for faster deployment or upgrade.
? 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.
? Multiple Spanning Tree Protocol (MSTP) provides a simple configuration to take
full advantage of redundant paths in the network and maximize network throughput.
? The Cisco 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 and to download the utility, visit www.cisco.com/go/findit.
? Performance and reliability: Cisco 250 Series switches have been tested to
deliver the high availability and performance 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.
? 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, pan-tilt-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 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 provide 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 increases network uptime in
the presence of an attack.
? 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
? Networkwide automatic voice deployment: Using a combination of Cisco Discovery
Protocol, LLDP-MED, 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.
? 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, you can take full advantage of IPv6-enabled
operating systems and applications in the future, without having to upgrade your
? 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
? Expansion ports: The Cisco 250 Series provides more ports per switch than
traditional switch models, giving you more flexibility to connect and empower
your business. Gigabit Ethernet models feature 26- and 50-port switches, versus
traditional devices that offer 20 or 44 ports with 4 shared ports. Fast Ethernet
models are now available with 4 Gigabit ports for even more flexibility in
deployment. The Cisco 250 Series also offers small form-factor pluggable (SFP)
expansion slots that give you the option to add fiber optic or Gigabit Ethernet
uplink connectivity to the switch. With the ability to increase the connectivity
range of the switches, you have more flexibility to design your network around
your unique business environment and to easily connect switches on different
floors or across the business.
