BDCOM 2448
Layer 2 SNMP Switch
BDCOM S2448 is the next-generation hi-performance L2 Ethernet switch with 48 Fast Ethernet ports. It has advanced architecture, 32 Gbps 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. BDCOM S2448 has a sub model, BDCOM S2448-DC.
S2448
Key Features
Performance
- 32Gbps switch fabric, wire-speed forwarding rate: 13.1 Mpps
- High port density. 48 Fast Ethernet ports, 4 Gigabit ports
- 80-km transfer by Gigabit optical fiber, direct connection to WAN
Security and reliability
- IEEE 802.1x and HTTP user authentication • Powerful ACL supports L2-L7 data filtering • Intelligent forwarding, complete defense against viruses like ‘Code Red’ or ‘Blaster’ • RPS power hot standby • Hardware MPLS solution offers hi-speed, powerful VPN • QinQ support. Double VLAN security
Easy maintenance
- Automatic recognition for straight-through or cross-over cables • Stackable physically and through cluster technology. Central management with unified IP address saves IP addresses • Management via CONSOLE port, Web, SNMP, Telnet, etc. • Support (BDCOM) Broad Director, HP Open View, Cisco Works 2000
Traffic and broadcast control
- Auto-detection and restraining of broadcast storm, IGMP snooping, effectively restrict broadcast flooding
- Full-and half-duplex traffic control
- Ethernet port rate limiting with 64 K step size
- IP multicast and QoS support
