Link aggregation (LACP) increases aggregated bandwidth, optimizing the transport of business critical data
IEEE 802.1s Multiple Spanning Tree, provides high link availability in multiple VLAN environments.
Support IEEE 802.1d/w Spanning Tree (STP/RSTP)
IGMP snooping allows the forwarding of multicast packets such as streaming audio and video, without increasing network broadcast congestion.
Non-blocking Layer 2 Switching Capacity
GVRP (GARP VLAN Registration Protocol) allows automatic learning and dynamic assignment of VLANs
Supports 4K active VLAN groups and 4K VLAN IDs
Q-in-Q increases the network scalability by providing a hierarchical structure
Supports 802.1P, Class of Service (CoS) with 4 priority queues per port
Rate limiting confines the traffic flow accurately according to the preset value
Supports multiple industry standard user authentication methods such as 802.1x, RADIUS Authentication, Supports 512 IP-MAC-Port-VID Binding entries
IP Source Guard prevents IP spoofing attacks such as DoS
Port Security enhances the security of all ports
L2/L3/L4 Access Control Lists restrict untrusted access to the protected resource
Virtual stackable provides high scalability and easy Single-IP-Management
Supports Telnet, Cisco like CLI, SNMP v1/v2/v3, RMON and web access
Supports SSL and SSH encryptions
Port Mirroring enables monitoring selected ingress/egress traffic
