Network security: Cisco 200 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 200 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, LLDP-
MED, Auto Smartports, and Voice Services Discovery Protocol (VSDP) – a unique patent-pending 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
make sure that your network is ready. Cisco 200 Series switches provide native support for IPv6 alongside
traditional IPv4. That means you can take full advantage of IPv6-enabled operating systems and
applications in the future, without having to upgrade your network equipment.
●
An energy-efficient solution: Cisco 200 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:
◦ Energy-Efficient Ethernet (EEE, the IEEE 802.3az standard), supported on Cisco 200 Series Gigabit
Ethernet switch models. EEE improves the efficiency of network equipment and provides standardized
signaling mechanisms that can enable rapid transitions between normal operation and low power idle
(LPI) states in systems on either end of the physical layer link.
◦ Automatic power down on Gigabit Ethernet ports when a link is not active.
◦ Embedded intelligence to adjust power based on cable length on Gigabit Ethernet models.
◦ Fanless design in most models, which reduces power consumption, increases reliability, and provides
quieter operation.
●
Additional Gigabit Ethernet ports: The Cisco 200 Series provides more ports per switch than other
switches in the market, 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. The Cisco 200 Series also offers mini Gigabit Interface Converter (mini-GBIC) 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.
