Cisco SF300-24P 24-Port 10/100 PoE Managed Switch

Ports

• 24 10/100 Ethernet RJ45
• 2x Gigabit Ports
• 2 x GBIC Combo Ports

Power over Ethernet (PoE)

• 802.3at Maximum power of 30W to any Gigabit Ethernet base port. Total power 180W

Security

• 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
• RADIUS/TACACS+
  • 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

Smartports

• 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.

General

• 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.

Buttons

• Reset button

Cabling Type
