The LNX-1212GN-SFP-T from Aaxeon Technologies is a managed redundant ring Ethernet switch with eight Gigabit combo ports and four 1000BaseX SFP ports. With complete support of Ethernet Redundancy protocol, Redundant Ring (recovery time < 20ms over 250 units of connection), and MSTP/RSTP/STP (IEEE 802.1s/w/D), the LNX-1212GN-SFP-T can protect your critical applications from network interruptions or temporary malfunctions with its fast recovery technology. It can provide advanced IP based bandwidth management that can limit the maximum bandwidth for each IP device. Users can configure IP cameras and NVR with more bandwidth and limit other device bandwidth. The LNX-1212GN-SFP-T also supports application-based QoS. Application based QoS can set the highest priority for data streams according to the TCP/UDP port number. This feature along with the IP police function, which can permit only allowed IP addresses with MAC addresses to access the network, helps prevent unwanted users from accessing IP surveillance networks without permission. The LNX-1212GN-SFP-T is one of the most reliable choices for highly-managed Gigabit Fiber Ethernet applications.
