Cisco SRW2016-K9 SG 300-20 20-port Gigabit Managed Switch

Rating: 3.8 stars - Model.ItemDetail.TFNumberOfUserReviews reviews

Ports

  • 18 Gigabit Ethernet RJ45
  • 2 x Gigabit/SFP Combo Ports

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

  • Unshielded twisted pair (UTP) Category 5 or better for 10BASE-T/100BASE-TX; UTP Category 5 Ethernet or better for 1000BASE-T

LEDs
