Voice VLAN | Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS |
Internet Group Management Protocol (IGMP) versions 1 and 2 snooping | IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups (16 for SG200-08 and SG200-08P) |

Storm control | Broadcast, multicast, and unknown unicast |
DoS prevention | DoS attack prevention |
Quality of Service | |
Priority levels | 4 hardware queues |
Scheduling | Strict priority and weighted round-robin (WRR) Queue assignment based on differentiated services code point (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) |
Rate limiting | Ingress policer, per VLAN and per port |
Power over Ethernet (PoE) | |
IEEE 802.3af PoE delivered on half of the RJ-45 ports within the listed power budgets | Maximum power of 15.4W to any 10/100 or Gigabit Ethernet base port supporting PoE. The total power available for PoE per switch is as follows: Power Dedicated to PoE: 180W Number of Ports That Support PoE: 24 |
IEEE 802.3af PoE Powered Device (PD) | Besides AC power, SG200-08 can work as PoE powered device (PD) and be powered by PoE switch connected to port 1. When both AC and PoE power are connected, PoE is preferred over AC, and AC will function as the backup to PoE power source. |
