Features
The list below highlights the significant protocols and features supported by the Switch.
• IEEE 802.3
• IEEE 802.3z
• IEEE 802.3x Flow Control in full-duplex compliant
• IEEE 802.3u
• IEEE 802.3ab
• IEEE 802.1p Priority Queues
• IEEE 802.3ad Link Aggregation Control Protocol for up to 32 groups per device, eight ports per group
• IEEE 802.1X Port-based and Host-based Access Control
• IEEE 802.1Q VLAN
• IEEE 802.1D Spanning Tree, IEEE 802.1w Rapid Spanning Tree and IEEE 802.1s Multiple Spanning Tree
support
• Jumbo frame to 13K Bytes
• Access Control List: Ingress ACL up to 768 profiles and 1.5K rules and Egress ACL up to 256 profiles and 512
rules
• ISM VLAN of up to five dedicated ISM VLANs, up to 512 multicast address ranges per ISM VLAN
• DHCP local relay
• Single IP Management
• Access Authentication Control utilizing TACACS, XTACACS, TACACS+, and RADIUS protocols
• Compound Authentication
• Power saving mode
• Simple Network Time Protocol (SNTP)
• System Log
• Maximum packet forwarding rate 65.48 million packets per second
• High performance switching engine performs forwarding and filtering at full wire speed up to 88Gps
• Full- and half-duplex for all ports. Full duplex allows the switch port to simultaneously transmit and receive data. It
only works with connections to full-duplex-capable end stations and switches. Connections to a hub must take
place at half-duplex.
• Unicast, broadcast, and multicast storm control
• Loopback Detection (LBD) v4.0 Trap
• Efficient self-learning and address recognition mechanism enables forwarding rate at wire speed
• Address table: up to 16 K
• Packet buffer memory of up to 2 MByte
• Two stacking ports in the rear of the switch
• VLAN Trunking
• Private VLAN
