Specifications

Performance
Capacity in Millions of Packets per Second (mpps) (64-byte packets) 13.1
Switching Capacity in Gigabits per Second (Gbps) 17.6
Layer 2 Switching
Spanning Tree Protocol (STP) Standard 802.1d Spanning Tree support
Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default
8 instances are supported
Multiple Spanning Tree instances using 802.1s (MSTP)
Port grouping Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
   + Up to 8 groups
   + Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation
VLAN Support for up to 4096 VLANs simultaneously Port-based and 802.1Q tag-based VLANs MAC-based VLAN
Management VLAN
Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks
Guest VLAN Unauthenticated VLAN
Dynamic VLAN assignment via Radius server along with 802.1x client authentication
CPE VLAN
Voice VLAN Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS.
Auto voice capabilities deliver network-wide zero touch deployment of voice endpoints and call control devices.
Multicast TV VLAN Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs (Also known as MVR)
Q-in-Q VLAN VLANs transparently cross a service provider network while isolating traffic among customers
Jumbo Frames Up to 9K (9216) bytes
Layer 3
IPv4 routing Wirespeed routing of IPv4 packets
Up to 512 static routes and up to 128 IP interfaces
Classless Inter-Domain Routing(CIDR) Support for CIDR
Layer 3 Interface Configuration of layer 3 interface on physical port, LAG, VLAN interface or Loopback interface
DHCP relay at Layer 3 Relay of DHCP traffic across IP domains
User Datagram Protocol (UDP) relay Relay of broadcast information across Layer 3 domains for application discovery or relaying of BootP/DHCP packets
DHCP Server Switch functions as an IPv4 DHCP Server serving IP addresses for multiple DHCP pools/scopes
Support for DHCP options
Security
Secure Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported
Secure Sockets Layer (SSL) SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management 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
Web Based Authentication Web based authentication provides network admission control through web browser to any host devices and operating systems.
STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port.
STP Root Guard This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes.
DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as a DHCP Server.
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.
Congestion avoidance A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization.
IPv6
IPv6 IPv6 host mode
IPv6 over Ethernet Dual IPv6/IPv4 stack
IPv6 neighbor and router discovery (ND) IPv6 stateless address auto-configuration
Path maximum transmission unit (MTU) discovery
Duplicate address detection (DAD) ICMP version 6
IPv6 over IPv4 network with Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) support
USGv6 and IPv6 Gold Logo certified
IPv6 QoS Prioritize IPv6 packets in hardware
IPv6 ACL Drop or rate limit IPv6 packets in hardware
IPv6 First Hop Security RA guard
ND inspection
DHCPv6 guard
Neighbor binding table (Snooping and static entries)
Neighbor binding integrity check
Multicast Listener Discovery (MLD v1/2) snooping Deliver IPv6 multicast packets only to the required receivers
IPv6 applications Web/SSL, Telnet server/SSH, ping, traceroute, Simple Network Time Protocol (SNTP), Trivial File Transfer Protocol (TFTP), SNMP, RADIUS, syslog, DNS client, Telnet Client, DHCP Client, DHCP Autoconfig, IPv6 DHCP Relay, TACACS
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 9K (9216) bytes supported on 10/100 and Gigabit interfaces
MAC table Up to 16K (16384) 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 (CDP) The switch advertises itself using the Cisco Discovery Protocol. It also learns the connected device and its characteristics via CDP.
