Smart Switch

Enhanced 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
The Cisco 220 Series Switch is 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.
High Performance and Reliability
This Cisco 220 Series Switch has 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
The Cisco 220 Series Switch is 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
- 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 non-employee 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 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.
Advanced Network Management Capabilities
- CLI. This switch can be managed using CLI. This can enable scripted or automated deployment for network professionals.
- Remote management. Using SNMP, you can set up and manage all switches and other Cisco devices in your network remotely.
- Dual image support. With the ability to maintain two images in permanent storage instead of only a single image that is traditionally supported on smart switches, you can perform software upgrades without taking the network offline or worrying about an outage because of a bad image file. This reduces switch downtime when the firmware is being upgraded or downgraded.
- Dual-configuration files support. Configure the device, validating that it is done correctly and then save this configuration to become effective after reboot. Additionally, a mirror configuration file provides automatic backup of the latest stable configuration file.
- IPv6 support. Cisco 220 Series Switches provide native support for IPv6, as well as the previous IPv4 standard. As a result, you can migrate to the next generation of networking applications and operating systems without an equipment upgrade.
Additional Gigabit Uplink Ports
This Cisco 220 Series Switch provides more ports per switch than other switches typically in the market, giving you more flexibility to connect and empower your business. This model features two Gigabit Ethernet combo ports in addition to the 48 copper ports, instead of traditional devices that offer two shared uplink ports with 46 ports. The mini-Gigabit Interface Converter (mini-GBIC) expansion slots in the combo ports give you the option to add fiber optic 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.
IP Telephony Support
This Cisco 220 Series Switch includes embedded QoS intelligence to prioritize delay-sensitive services such as voice and video. They can simplify unified communications deployments, and help ensure consistent network performance for all services. 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.
