  • Fast, easy setup and configuration: Cisco 300 Series Switches are designed to be easy to use and manage by small businesses and the partners who serve them. The included device manager software provides an intuitive, web-based interface to simplify setup, security, and quality of service (QoS) traffic prioritization, allowing even users without IT expertise to configure the switch in minutes. Cisco also provides a Cisco FindIT Network Discovery Utility. This utility that works through a simple toolbar on the user’s web browser to discover Cisco devices in the network and display basic information, such as serial numbers and IP addresses, to aid in the configuration and deployment of Cisco Small Business products. For more information, and to download the utility, please visit www.cisco.com/go/findit. These switches use Cisco Discovery Protocol as well as Link Layer Discovery Protocol (LLDP-MED) to automatically detect all the devices connected to your network, and then automatically configure themselves for the appropriate connectivity and instructs the devices to use appropriate voice VLAN or QoS parameters. For more advanced capabilities and hands-on control, the switches support Smartport roles which configure the 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 applies the intelligence delivered through the Smartport roles and applies it automatically to the port based on the devices discovered over CDP or LLDP-MED. This facilitates zero touch deployments. Although the Cisco 300 Series is designed to be deployed without using a command-line interface (CLI), Cisco Textview is available for those who prefer to use text-based configuration. Together, these features reduce the time your staff must devote to network deployment, management, and troubleshooting.
  • Strong security: The Cisco 300 Series Switches provide a high level of security and give you finegrained control to safeguard your network from unauthorized users. Advanced security features include:
    • Embedded security to protect management data traveling to and from the switch and encrypt network communications
    • Extensive access control lists (ACLs) to restrict sensitive portions of the network from unauthorized users and guard against network attacks
    • Guest virtual LANs (VLANs) to let you provide Internet connectivity to nonemployee users while isolating critical business services from guest traffic
    • Support for advanced network security applications such as IEEE 802.1X port security to tightly limit access to specific segments of your network
    • Time based ACLs and Port Operation restrict access to the network during predesignated times, such as business hours.
    • Security mechanisms such as, Bridge Protocol Data Unit (BPDU) Guard and broadcast/multicast/unknown unicast storm control, protect the network from invalid configurationsor malicious intent.
    • Secure Core Technology (SCT) helps ensure that the switch will receive and process management and protocol traffic no matter how much traffic is received.
    • Advanced defense mechanisms, including Dynamic ARP Inspection (DAI), IP Source Guard, and Dynamic Host Configuration Protocol (DHCP) snooping, detect and block deliberate networkattacks. Combinations of these protocols are also referred to as IPMB (IP-MAC-port binding)
    • DOS (denial-of-service) attack prevention maximizes network uptime in the presence of an attack
    • Protection of management sessions using Radius, TACACS+ and local database authentication as well as secure management sessions over SSL, SSH, and SNMPv3.
  • Power over Ethernet: Cisco 300 Series Switches are available with up to 48 PoE ports of Fast Ethernet or 28 PoE ports of Gigabit Ethernet connectivity. This capability simplifies advanced technology deployments such as IP telephony, wireless, and IP surveillance by allowing you to connect and power network endpoints over a single Ethernet cable. With no need to install separate power supplies for IP phones or wireless access points, you can take advantage of advanced communications technologies more quickly, and at a lower cost.
  • IP telephony support: Cisco 300 Series Switches include embedded QoS intelligence to prioritize delay-sensitive services such as voice and video, simplify unified communications deployments, andhelp ensure consistent network performance for all services.

The switch automatically configures the device with the right VLAN and QoS parameters to prioritize voice traffic.
  • Networkwide Automatic Voice Deployment: Using a combination of CDP, LLDP-MED, Auto Smartports, and VSDP (Voice Services Discovery Protocol – a unique patent-pending Cisco protocol), customers can deploy an end-to-end voice network dynamically. The switches in the network automatically converge around a single voice VLAN and 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.
  • Advanced network management capabilities: As managed switches, the Cisco 300 Series lets you use a variety of advanced features to control traffic over your network.
  • Features include:
    • Static routing/Layer 3 switching between VLANs: 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.
    • IPv6 support: As the IP network addressing scheme evolves to accommodate more devices, you can make sure that your network is ready. The Cisco 300 Series provides native support for IPv6, the newest version of the Internet Protocol, as well as the previous IPv4 standard. As a result, you will be able to move up to the next generation of networking applications and operating systems without an extensive equipment upgrade.
    • Dual image support: With the ability to maintain dual images of your switches, you can perform software upgrades without having to take the network offline and without worrying about an outage during an upgrade.
    • Dual Configuration files support: Allows configuring the device, validating that it is configured correctly and then saving this configuration to become effective after reboot. Additionally, a mirror configuration file, providing automatic back-up of the latest stable configuration file maximizes network uptime.
    • Remote management: Using Simple Network Management Protocol (SNMP), you can set up and manage all switches and other Cisco devices in your network remotely, instead of having to directly connect to them.
    • Additional management options: The switches can be fully managed using the Web GUI or using a full command-line interface (CLI).
  • Optimal energy efficiency: Cisco 300 Series Switches are designed with a variety of power-saving features across all models, providing the industry’s broadest portfolio of “green” switches. These switches optimize power use to protect the environment and reduce energy costs, without compromising performance. Power-saving features include:
    • The latest application-specific integrated circuits (ASICs), using low-power 65-nanometer technology (these chipsets allow for lower power consumption and thinner, more efficient designs)
    • 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 signal strength based on cable length
    • Fanless design in most models, which reduces power consumption, increases reliability, and provides quieter operation
    • LEDs can be turned off to conserve power
  • Expansion ports: The Cisco 300 Series provides more ports per Gigabit Ethernet switch than traditional switch models, giving you more flexibility to connect and empower your business. Gigabit Ethernet models feature 28- and 52-port switches, versus traditional devices that offer 20 or 44 ports with four shared ports giving you more value. The Cisco 300 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.

Remote Monitoring (RMON)

Embedded RMON software agent supports 4 RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis

IPv4 and IPv6 dual stack

Coexistence of both protocol stacks to ease migration

Firmware upgrade

• Web browser upgrade (HTTP/HTTPS) and TFTP
• Upgrade can be initiated through console port as well
• Dual images for resilient firmware upgrades

Port mirroring

Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to 8 source ports can be mirrored to one destination port. A single session is supported.

VLAN mirroring

Traffic from a VLAN can be mirrored to a port for analysis with a network analyzer or RMON probe. Up to 8 source VLANs can be mirrored to one destination port. A single session is supported.

DHCP (Options 12, 66, 67, 82, 129, and 150)

DHCP Options facilitate tighter control from a central point (DHCP server) to obtain IP address, auto-configuration (with configuration file download), DHCP relay, and hostname

Secure Copy (SCP)

Securely transfer files to and from the switch.

Autoconfiguration with Secure Copy (SCP) file download

Enables secure mass deployment with protection of sensitive data.

Text-editable config files

Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment

Smartports

Simplified configuration of QoS and security capabilities

Auto Smartports

Applies the intelligence delivered through the Smartport roles and applies it automatically to the port based on the devices discovered over CDP or LLDP-MED. This facilitates zero touch deployments.

Textview CLI

Scriptable command-line interface. A full CLI as well as a menu-based CLI is supported

Cloud services

Support for Cisco Small Business FindIT Network and Cisco OnPlus

Localization

Localization of GUI and documentation into multiple languages

Other management

Traceroute; single IP management; HTTP/HTTPS; SSH; RADIUS; port mirroring; TFTP upgrade; DHCP client; BOOTP; SNTP; Xmodem upgrade; cable diagnostics; ping; syslog; Telnet client (SSH secure support)

Time-based port operation

Link up or down based on user-defined schedule (when the port is administratively up).

Login banner

Configurable login banners for web as well as CLI.

Power Efficiency

EEE Compliant (802.3az)

Supports 802.3az on all copper ports (SG300 models).

Energy Detect

Automatically turns off power off on Gigabit Ethernet and 10/100 RJ-45 port when detecting link down

Active mode is resumed without loss of any packets when the switch detects the link up

Cable length detection

Adjusts the signal strength based on the cable length for Gigabit Ethernet models. Reduces the power consumption for cables shorter than 10m.

Disable port LEDs

LEDs can be manually turned off to save on Energy

General

Jumbo frames

Frame sizes up to 10 KB supported on 10/100 and Gigabit interfaces

MAC table

Up to 16000 MAC addresses

Discovery

Bonjour

The switch advertises itself using the Bonjour protocol.

Link Layer Discovery Protocol (LLDP) (802.1ab) with LLDP-MED extensions

LLDP allows the switch to advertise its identification, configuration, and capabilities to neighboring devices that store the data in a MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones.

Cisco Discovery Protocol

The switch advertises itself using the Cisco Discovery Protocol.
