Support IP Source Guard feature to prevent illegal address spoofing including MAC spoofing, IP spoofing, and MAC/IP spoofing, as well as DoS attacks caused by large-traffic address spoofing.
Provides the DHCP Snooping (listening) function. By establishing and maintaining the DHCP Snooping binding table, it can monitor the MAC address, IP address, lease period and other information of the access user, and solve the problem of IP and port tracking and positioning of DHCP users.
Complete reliability protection mechanism, convenient management, and maintenance
The BH-248GE-4X-SFP switch uses the CPU protection policy to classify and limit the flow rate of the packets sent to the CPU to avoid the attack and resource consumption of the illegal attack packets on the CPU;
Support STP, RSTP, MSTP, and other spanning tree protocols, fast convergence, improve fault tolerance, ensure stable network operation and link load balancing, rational use of network channels, and improve redundant link utilization;
Supports industrial-grade Ethernet ring network protocol ERPS, provides millisecond-level fast service switching performance and ensures uninterrupted services. Moreover, the protocol is simple and reliable, the switching performance is high, the maintenance is convenient, and the topology is flexible, which can greatly facilitate users to manage and plan the network;
