Introduction:
3onedata IES2448C is the next-generation hi-performance L2 Ethernet
switch with 48 Fast Ethernet ports, plus 4 gigabit ports. It has
advanced architecture, 36Gbps switch fabric, and 13.1 Mpps
forwarding rate. Its hardware wire-speed switching capability
provides a powerful, multi-layer solution not only for enterprises,
but also for Internet Service Providers (ISP’s) and telecom
carriers.
Features:
Performance
1. 36 Gbps switch fabric, hardware routing, wire-speed
L2 forwarding rate: 13.1 Mpps
2. High port density.48 Fast Ethernet ports,2 Gigabit
Ethernet ports,2 Gigabit SFP slots
3. 80-km transfer by Gigabit optical fiber, direct
connection to WAN
Security and reliability
1. IEEE 802.1x and other methods for user
authentication
2. Powerful ACL supports L2-L7 data filtering
3. Intelligent forwarding, complete defense against
viruses like ‘Code Red’ or ‘Blaster’
4. RPS power hot standby
5. QinQ support. Double VLAN security
Easy maintenance
1. Automatic recognition for straight-through or
cross-over cables
2. Stackable physically and through cluster
technology. Central management with unified IP address saves IP
addresses
3. Management via CONSOLE port, Web, SNMP, Telnet,
etc.
4. Support Broad Director, HP Open View, Cisco Works
2000
Traffic and broadcast control
1. Auto-detection and restraining of broadcast storm,
IGMP snooping, effectively restrict broadcast flooding
2. Full- and half- duplex traffic control
3. Ethernet port rate limiting with 1 M step size
4. L2 multicast and QoS support
5. Jumbo frame
