Vlastnosti:
48x 10/1001000Mbps RJ45 port, 4x 1Gbps SFP port ,1x console port
Excellent performance
192Gbps backboard bandwidth, uncongested design and full wire-speed forwarding.
Gigabit optical-fiber transmission with up to 80Km distance and directly connecting the MAN backbone network.
High security and reliability
Providing multiple user authentication modes such as 802.1x authentication.
Powerful ACL and hardware supporting L2 to L7 data filtration.
Port-MAC-IP bind.
Special ARP invasion detection to effectively stop ARP cheat.
Flexible and various management
The straight-through cable and the intercrossed cable can be automatically identified.
Adopting the cluster technology; supporting device cascading; managing uniquely through a unique IP address; saving address resources.
Multiple management modes such as Console port, Telnet, Web and SNMP are supported.
Supporting multiple general network management protocols like Broad Drictor, HP Open View and Cisco Works 2000.
Powerful flow and broadcast management.
The detection of IGMP packets is supported.
The flow control can be realized in full-duplex mode or half-duplex mode.
The rate limitation in a minimum step of 64K is supported on the Ethernet interface.
IP multicast and QoS are supported.
Specifikace:
Forwarding rate:
Full wire-speed filtering and forwarding
Switching mode:
Store forwarding
Address table:
8K
Queue buffer:
64MB
Flow Control:
Backpressure is adopted for half-duplex, while IEEE802.3x is adopted for full-duplex.
Broadcast control:
The broadcast storm is constrained. When the threshold value for controlling the broadcast storm is reached, the broadcast packets are stopped from being forwarded.
Multicast control:
Automatically monitoring IGMP packets
Service quality:
Two transmission queues on each port are mapped to eight priority values of 802.1p.
Interface binding :
Eight interfaces can be bound in a group through dynamic LACP or static aggregation, and 12 groups can be supported simultaneously.
Cascading:
Cluster
Bridging:
IEEE 802.1D-1998 spanning tree, path backup, IEEE 802.1w（RSTP）
VLAN:
