GL2000 switchseries is a new generation of L2 switches with high performance, multiservice,high reliability and high security that are independently developed by XDK.They support all kinds of connections varying from 10/100M to 1000M, so thenetwork can be configured flexibly according to actual needs. The switches canaccess all Ethernet or fast-Ethernet devices, so they can be very compatiblewith the existing devices.

Properties

Excellent performance

n  32Gbps backplane bandwidth, hardware forwarding and wire-speed L2 packet forwarding rate

n  Gigabit optical-fiber transmission with up to 80Km distance and directly connecting the MAN backbone network

High security and reliability

n  Providing multiple user authentication modes such as 802.1x authentication

n  Powerful ACL and hardware supporting L2 to L7 data filtration

n  Port-MAC-IP  bind

n  Special ARP invasion detection to effectively stop ARP cheat

n  Hardware IPv6 ACL

Flexible and various management modes

n  Automatically identifying the straight-through cable and the intercrossed cable

n  Adopting the cluster technology; supporting device cascading; managing uniquely through a unique IP address; saving address resources

n  Multiple management modes such as Console port, Telnet, Web and SNMP are supported.

Powerful flow and broadcast management

n  Detecting and limiting broadcast storms automatically and supporting IGMP snooping to limit broadcast flooding

n  Supporting flow control in full-duplex mode or half-duplex mode

n  The rate limitation in a minimum step of 64K is supported on the Ethernet interface.

n  Supporting IP multicast and QoS

n  Flexible QinQ realizes the QinQ function based on the five-element group.

Varied protocols

n  POE switches support 802.3af power supply on all their ports.

n  POE switches already support 802.3at power supply. The maximum power supply on each port can reach up to 30W.

n  POE switches support the configuration of power-supply priority, guaranteeing continuous power supply at those key network nodes.

n  The POE switches support configuring the power consumption of power supply on their ports, saving the power and reducing users’ cost.
