Cisco SG300-28MP-K9-NA overview

  • 1Description

The SG300-28MP 28-Port PoE Gigabit Ethernet Switch from Cisco allows small businesses to connect its employees with each other and with all of the servers, printers, IP phones, and other devices they use. This mountable switch offers 128MB of RAM, 16MB flash memory, and 26 Gigabit Ethernet plus 2 Gigabit Ethernet Combo ports. 24 of these ports are PoE ports, which provide power over a single Ethernet cable to devices such as IP telephony, wireless, and IP surveillance. It also prioritizes services such as voice and video to help ensure consistent network performance for all services. For security to keep your network safe, this switch features denial-of-service prevention, guest virtual LANs, access control lists, and more.

Cisco has included a device manager software that provides a web-based interface to guide users without IT experience in setup, security, and quality of service traffic prioritization. Cisco has other features that automatically detects the devices connected to the network and displays the serial numbers and IP address. It then instructs the devices to use the appropriate bandwidth parameters and the specific level of security. Included with the switch are a power cord, mounting hardware, serial cable, and a CD-ROM disc.

Setup and Configuration
The included device manager software provides an intuitive, web-based interface to simplify setup, security, and quality of service 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. 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. 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.
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. Web based authentication provides a consistent interface to authenticate all types of host devices and operating systems, without the complexity of deploying IEEE 802.1X clients on each endpoint.
  • 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 configurations or 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 network attacks. Combinations of these protocols are also referred to as IPMB (IP-MAC-port binding).
  • IPv6 First Hop Security extends the advanced threat protection to IPv6. This comprehensive security suite includes ND inspection, RA guard, DHCPv6 guard and neighbor binding integrity check, providing unparalleled protection against a vast range of address spoofing and man in the middle attack on IPv6 networks.
  • 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
    Use advanced technologies 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
    This switch includes embedded QoS intelligence 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 CDP, LLDP-MED, Auto Smartports, and VSDP, you 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.
    Network Management Capabilities
  • 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, as well as the previous IPv4 standard. As a result, you will be able to use 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
  • Energy Efficiency
  • 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
    This switch 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.
    Multiple Languages
    Available in seven languages: English, French, German, Italian, Spanish, Japanese, and simplified Chinese. All product user interfaces and documentation are translated, giving you the ability to select your preferred language.
