Security
802.1x Radius authentication, DHCP snooping, IP-MAC binding, port security supports limited dynamic lock and
locked MAC address (256 max entries per port), DOS Attack Prevention, Port Isolation (Protected Ports)
Link Aggregation IEEE 802.3ad LACP, up to 8 groups with up to 8 ports per group
Bandwidth Control Rate limit according to network speed, 12kbps~1000Mbps: in steps of 16kbps
Storm Control Support broadcast/unknown multicast/unknown unicast 16kbps~1000Mbps: in steps of 16kbps
Loopback Detection Detects and prevents loops in the network by sending out loop protocol packets and shutting down affected ports

IGMP Snooping/Querier
IGMP (v1/v2/v3) snooping provides for fast client joins and leaves of multicast streams and limits
bandwidth-intensive video trafc to only the requestors; supports 256 multicast groups
MLD Snooping/Querier Support v1, MLD snooping fast leave (per- vlan), MLD querier, Dynamic router port, Static/forbidden router, Report suppression
DHCP IPv4 DHCP Relay, IPv4 DHCP Relay Statistics, IPv4 DHCP Snooping
L3 Static Routing IPv4 (63 max entries), IPv6 (21 max entries)
L3 IP Multicast IGMP, MLD, L3 IP Multicast Routing

QoS Priority Levels 8 hardware queues
Scheduling Strict, Weighted Round Robin (WRR) and Strict + WRR
Class of Service Port-based, 802.1p priority-based, IPv4/v6 IP DSCP-based
Auto Voice VLAN Voice trafc is automatically assigned by OUI to a voice-specic VLAN and treated with appropriate levels
