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
