BAUDCOM BD-S2448C switch provides not only the hi-performance and multilayer communication solutions for enterprises but also the powerful support for ISPs to be upgraded to data networks. BD-S2448C switch provides hardware wire-speed switching and supply enterprise high-performance and multilayered solutions, so it is ideal for constructing the remote switch-platform of hi-speed enterprise networks. This switch series is suitable for ISPs, especially those large carriers, because these switches can improve their competition on the IP market.
Main Characteristics

- Powerful ACL and hardware supporting L2 to L7 data filtration
- QinQ
- Special ARP invasion detection to effectively stop ARP cheat
Flexible management mode
- Automatically identifying the straight-through cable and the intercrossed cable
- Adopting the cluster technology; supporting device stacking; managing uniquely through a unique IP address; saving address resources
- Supporting multiple management modes such as Console port, Telnet, Web and SNMP
- Supporting multiple general network management protocols like Broad Director, HP Open View and Cisco Works 2000
Powerful flow and broadcast management
- Automatically detecting and controlling broadcast storms, monitoring IGMP packets and effectively preventing broadcast packet's flooding
- Supporting flow control in full-duplex mode or half-duplex mode
- The rate limitation in a step of 64K is supported on the Ethernet interface.
-
Supporting IP multicast and QoS
