Performance
- 24Gbps non-blocking switching fabric
- 17.8 million packet-per-second forwarding rate
- Flexible design for both Gigabit copper and Gigabit fiber connectivity
- 1488000pps forwarding rate for 1000Base-T/1000Base-S connectivity, 148800pps forwarding rate for 100Base-Tx connectivity
- Wire-speed performance

MAC and Packet Buffer
- 16K MAC entries
- 8Mbits packet buffer

Access Control List
- Wire speed filtering per MAC/IP/TCP/UDP
- Wire speed rate limiting per MAC/IP/TCP/UDP
- Wire speed mirroring per MAC/IP/TCP/UDP

Traffic Management and QoS
- IEEE 802.1p
- 8 egress queues per port for different types of traffic
- WFQ (Weighted Fair Queue) scheduling for different prioritization of packets
- Strict priority queuing for highest priority packets to get best service
- IEEE 802.1Q tag-based and port-based VLAN
- 256 static VLAN, up to 4K dynamic VLAN
- Support GVRP, automatic VLAN member registration
- Supports jumbo frame, up to 9K Bytes
- Supports IGMP snooping
- Congestion control on all ports

Rate Limiting
- Allow bandwidth to be shaped in steps at 64Kbps
- Rate limiting based on combination of L2/L3/L4 fields using ACL

Link Aggregation
- IEEE 802.3ad compliant
- Support LACP, static and dynamic link aggregation
- Up to 6 aggregation groups
- 8 ports per group randomly selected

Redundancy for Fault Backup
- IEEE802.1w Rapid Spanning Tree Protocol(RSTP) provides rapid convergence of spanning tree independent of spanning-tree timer
- Supports ZyXEL Backup Power System (BPS) that provides internal power source redundancy, improve fault tolerance

User Security and Authentication
- MAC filtering per port secures access to each port
- Specific MAC forwarding per port: only specified MAC addresses can access the network (port lock)
- Limit the number of MAC address per port
- 802.1x port-based security, prevent unauthorized client access to the network
- Private VLAN provides security and isolation between ports on a switch, ensures that users can not snoop on each other’s traffic
