6 kV professional lightning protection: Built-in professional lightning protection circuit, support 6KV port lightning pro-tection, effectively reduce the damage caused to the network system by thun-derstorms, and improve the robustness of the system.

12M large buffer: Provides a large 12Mb buffer, which can meet the network application require-ments of large traffic bursts such as engine search, IPTV, P2P download, and no packet loss during traffic bursts.

Rich security features: Supports IP address filtering, MAC address filtering, ARP filtering, DoS attack defense, and ACL access control list, improving network security.

Layer-3 routing protocol: Supports Layer-3 static routing protocol, meeting the demand of the 3-layer networking environment in which Layer-3 networks should be interconnected while Layer-2 networks should be isolated, thus realizing an efficient and fast layer-3 routing forwarding.
