The ComNet CNGE24MS2 has eight 100/1000Base-FX SFP ports and sixteen Gigabit combo ports that allow for TX or FX transmission. All SFP ports utilize ComNet SFP modules for fiber and connector type and distance. The IEEE802.3-compliant unit offers multiple Ethernet redundancy protocols (ComRing, C-Ring, and MSTP/ RSTP/STP) which protect your applications from network interruptions or temporary malfunctions by redirecting transmission within the network. The switch provides advanced IP-based management that can limit the maximum bandwidth for each connected IP device, allowing the user to adjust usage. Application-based QoS can set a higher priority for data streaming. The Device-Binding function can prevent unauthorized network access, increasing security. The unit also provides advanced DOS/DDOS auto prevention. If IP flow becomes too large, too quickly, the switch will lock the source IP address for a set period preventing unauthorized access.Features Internal Power Supply 19 inch rack mountable design MSTP/RSTP/STP (IEEE 802.1s/w/D) Fast Redundant Ethernet Ring: C-Ring (recovery time <20ms over 250 units of connection) Com-Ring open architecture supports other switch manufacturers'' ring technologies, for seamless network integration TOS/Diffserv supported Quality of Service (802.1p) for real-time traffic VLAN (802.1Q) with VLAN tagging and GVRP supported IGMP v2/v3 (IGMP snooping support) for filtering multicast traffic Supports IP-based bandwidth management Supports application-based QoS management Supports DOS/DDOS auto prevention Port configuration, status, statistics, monitoring, security Features 100/1000Base-FX SFP Ports Supports SMTP client DDM (Digital Diagnostic Monitoring) remotely ascertains the status of the operating voltage, current, and operating temperature of the SFP modules Supports SNMP v1/v2c/v3 & RMON & 802.1Q VLAN Network Management Supports ACL, 802.1x User Authentication for security Supports 9.6K Bytes Jumbo Frame Multiple notifications warn of unexpected events Web-based, Telnet, Console (CLI), and Windows-based utility (eConsole) configuration Supports Link Layer Discovery Protocol (LLDP) Supports IPV6 new internet protocol version Provided HTTPS/SSH protocol enhances network security Supports Device Binding security function Features 100/1000Base-X SFP Combo Ports DHCP Client/Server
