Layer Three Switch

Characteristic

Ø Hardware supporting 2/3 layer linear rate of exchange, to be able to identify and deal with the data of the 4-7 layer flow control.

Ø The longest matching strategy based on routing, ensure equal bales forwarding forwarding performance. Can protect network by code red and worm attacks, ensure the safety equipment.

Ø Supports 802.1x authentication protocol, can identify the identity of the user access network.

Ø Support center MAC address verification, through the port and the MAC address for network access control. And at the same time the 802.1x authentication and MAC address validation.

Ø Through any binding MAC, IP and port to support the unauthorized network access.

Ø Based on source / destination MAC address, a source / destination IP address, and a port and protocol of 2-4 layer complex flow classification.

Ø Support flexible queue scheduling algorithm, can simultaneously in port and queue reference set. Support the strict priority strategy ( SP ), weight ( WRR ) and SP+WRR polling, as well as 8 priority queue.

Ø Support client access speed control, the size limit to 64Kbit/s exchange rate.

Ø Aggregation port synchronization queue scheduling, the characteristics for aggregation port group for each port is provided in the queue synchronization scheduling function.

Ø Support configuration protocol data packet priority, each packet having its own priority. Customers can use the QoS command to modify the protocol packet priority.

Ø Of simple network management protocol ( SNMP ) version of the 1/2/3, RMON V1, 1/2/3/9 group management information base ( MIB ), NMS conducted by management. These can be used for general network management platforms such as OpenView, QuidView network management system to manage.

Ø Supports command line mode, network management based on Web, Modem dial-up and Telnet, make equipment management to be more convenient.

Ø Support SNMP agent logging, administrators can use SNMP remote web log management operation.
