Cisco 220 Series Switches have been rigorously tested to help ensure easy integration and full compatibility with these and other vendor products.
Raising the Bar for Smart Switches
Smart switches are typically priced low but are limited in functionality and scalability. Cisco 220 Series Smart Plus Switches raise the bar for the smart switches by providing additional features and enhancements, including:
- A higher level of security and intelligence. ACLs and flow-based QoS give you more control over network performance, maintain the integrity of key business information, and can enable higher network efficiency.
- Simple and flexible management. Cisco 220 Series Switches are easy to deploy and use, not only for small, self-installed deployment by non-IT professionals, but also for mid-scale deployment by IT engineers. These switches provide more management options like Cisco CLI, Simple Network Management Protocol (SNMP), Cisco Prime™ LAN Management System (LMS) integration, besides the intuitive, web-based interface and Cisco FindIT utility.
- Power Over Ethernet Plus. PoE+ streamlines the deployment for wireless access points, IP telephony, and video surveillance by allowing power and data to run over a single network cable. In addition to PoE support on all copper ports, Cisco 220 Series Switches also support PoE+ on selected ports, which is up to 30 watts of power per port. PoE+ can enable deployments for 802.11ac wireless access points, Pan Tilt Zoom (PTZ) IP cameras, videophones, and thin client devices, delivering more flexibility and investment protection.
In addition, the Cisco 220 Series provides a rich set of features that help you create business-class networks. These features deliver a comprehensive solution to simplify the operation, increase uptime, and ultimately get your business better connected to employees, customers, and suppliers. Some primary features include:
High performance and reliability.
Cisco 220 Series Switches have been tested to deliver the high availability and performance that users have come to expect from Cisco switches. The switches speed up file transfer times, keep vital business applications available, and help your employees respond more quickly to customers and each other. With enhanced QoS capabilities, the Cisco 220 Series also gives you the flexibility to manage and prioritize high-bandwidth traffic so you can easily integrate all the business communications and connectivity needs on a single converged infrastructure.
Optimal energy efficiency.
Cisco 220 Series Switches are designed with Energy Efficient Ethernet (IEEE 802.3az) and Energy Detect support on all models, as well as fanless designs on selected models. These designs help you save operational expenses and reduce your environmental footprint.
Enhanced network security.
The Cisco 220 Series Switches provide new levels of security for smart switches and deliver more ways to safeguard your network.
- Extensive ACLs can restrict sensitive portions of the network from unauthorized users and guard against network attacks.
- Support for network security applications such as IEEE 802.1X and port security can tightly limit access to specific segments of your network.
- Guest virtual LANs (VLANs) let you provide Internet connectivity to nonemployee users while isolating critical business services from guest traffic.
- Security mechanisms such as broadcast/multicast/unknown unicast storm control and Bridge Protocol Data Unit (BPDU) guard can protect the network from invalid configurations or malicious intent.
- Denial-of-service (DOS) attack prevention helps to increase uptime in the event of a network attack.
- Embedded security can protect management data traveling to and from the switch and encrypt network communications.
- Protect management sessions using RADIUS, TACACS+, and support local database authentication as well as secure management communication over SSL, SSH, and SNMPv3.
Easy configuration and management.
Cisco 220 Series Switches are designed to be easy to deploy and use by small- and medium-sized businesses or the partners that manage them. The simple and intuitive web-based interfaces allow even users without IT expertise to configure, manage, and troubleshoot the switch in minutes. Other ease-of-use features include:
- Cisco Discovery Protocol (CDP) and Link Layer Discovery Protocol (LLDP-MED). Automatically detect all the devices connected to your network. Then automatically configure the switch itself with the appropriate settings and instruct the end devices on the appropriate voice VLAN or QoS parameters to use.
- Cisco FindIT Network Discovery Utility. This feature works through a simple toolbar on the user's web browser to discover Cisco devices on the network and display basic information, such as serial numbers and IP addresses. This aids in quicker configuration and deployment of Cisco Small Business products.
