Cisco SG 300 16 Port Gigabit Managed Switch 2 GbE & 2 combo Gb SFP Slots

The Cisco 300 Series is broad portfolio of fixed-configuration managed Ethernet switches. Models are available with 8 to 48 ports of Fast Ethernet and 10 to 52 ports of Gigabit Ethernet connectivity, providing optimal flexibility to create exactly the right network foundation for your business. However, unlike other small business switching solutions that provide managed network capabilities only in the costliest models, all Cisco 300 Series Switches support the advanced security management capabilities and network features you need to support business-class data, voice, security, and wireless technologies.

  • 20 Port Gigabit Ethernet ( 18x 10/100/1000 ports / 2x Combo mini-GBIC ports)
  • Built-in switch configuration utility for easy browser-based device configuration (HTTP/HTTPS). Supports configuration, system dashboard, system maintenance, and monitoring.
  • Limited lifetime with next business day advance replacement (where available)



Form Factor Desktop (Casing: Metal)

  • Secure Shell (SSH) Protocol
    • SSH secures Telnet traffic to and from the switch
  • Secure Sockets Layer
    • (SSL) SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based managemen GUI in the switch
  • IEEE 802.1X (Authenticator role)
    • 802.1X: RADIUS authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN,
    • single/multiple host mode and single/multiple sessions
    • Supports time-based 802.1X
    • Dynamic VLAN assignment
  • Layer 3 isolation
    • Allow/disallow routing between IP subnets or directly connected IP networks
  • Layer 2 isolation Private VLAN Edge (PVE) with community VLAN
    • PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks
  • Port security
    • Locks MAC addresses to ports, and limits the number of learned MAC addresses
    • Supports RADIUS and TACACS authentication. Switch functions as a client
  • Storm control
    • Broadcast, multicast, and unknown unicast
  • DoS prevention
    • DoS attack prevention
  • Congestion avoidance
    • A TCP congestion avoidance algorithm is required to minimize and prevent global
    • CP loss synchronisation.
  • ACLs
    • Support for up to 512 rules
    • Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point (DSCP)/IP precedence, TCP/ UDP source and destination ports, 802.1ppriority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag

Quality of Service

  • Priority levels
    • 4 hardware queues
  • Scheduling
    • Strict priority and weighted round-robin (WRR) Queue assignment based on DSCP and class of service (802.1p/CoS)
  • Class of service
    • Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/type of service (ToS)/DSCP based;
      Differentiated Services (DiffServ); classification and re-marking ACLs, trusted QoS
  • Rate limiting
    • Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based

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 analyser or RMON probe. Up to 8 source VLANs can be mirrored to one destination port. A single session is supported.

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

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

Text-editable config files

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


  • Simplified configuration of QoS and security capabilities

Secure copy

  • Securely transfer files to and from the switch

Textview CLI

  • Scriptable command-line interface

Cloud services

  • Support for Small Business Toolbar application

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)

Power Efficiency

  • Energy Detect Automatically turns off power off on Gigabit Ethernet 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. Reduces the power consumption for cables shorter than 10m.


  • Jumbo frames Frame sizes up to 10 KB supported on 10/100 and Gigabit interfaces
  • MAC table Up to 8000 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.


  • Reset button
