Metro Aggregation Gigabit switch, L2+, 12 Gigabit combo (open SFP/RJ45), dual AC/DC power, 0°+65°C 16 K MAC address table Policy-based QoS optimizes multi-service quality IGMP snooping v1, v2, v3, MVR Multilayer-aware (L2/L3/L4) ACL for security protection High redundancy and resilient architecture with RSTP and port trunking Temperature harden and protection against humidity and dust Removable fan module IPv6 management support Telco-class Layer 2 Gigabit Carrier Ethernet Switch The MGS3700-12C 12-port Combo GbE L2 Managed Switch is specially designed for service providers to deliver profitable Ethernet services. With the high-performance hardware platform, service providers can easily extend network topologies while enabling robust security, QoS and management functions to help customers fulfilling differentiated needs for Metro Ethernet services. Advanced QoS for significant services Consistent service quality and reliable connecting ability in a converged network is the key for service providers to win customers and build loyalty; therefore the ability to control traffic flow and set traffic policy becomes more critical than ever. The MGS3700-12C offers wire-speed flow control that classifies and prioritizes the incoming packets according to the predefine QoS policies that meet requirements of service providers. In terms of classification, the Differentiated Services Code Point (DSCP) field and the 802.1p class of service (CoS) field are identified to assess the priority of incoming packets. Classification and reclassification can be based on criteria as specific as rules based on IP, MAC addresses, VLAN ID or TCP/UDP port number. For bandwidth management, the MGS3700-12C provides 8 priority queues per port for different types of traffics, allowing service providers to set rule-based rate limitations that take full advantage of constrained network resources and guarantee the best performance. Enhanced security for protection among customers Avoiding subscribers affecting each other on a shared network or shared device is a major concern for service providers. The MGS3700-12C offers a complete set of security features to protect user data while administrating the traffics. The intrusion lock function detects the “plugged” and “unplugged” status change of Ethernet cables, and the switch would deactivate a specific port automatically if needed, and the 802.1X authentication can secure the network from unauthorized users. Port security provides the ability to deny unauthorized users from accessing the network. Moreover, the 802.1X feature cooperating with RADIUS is useful to prevent unauthorized access based on username and password (or other credentials) and acts as powerful access control for converged networks with mixed wired and wireless access. The MGS3700-12C provides a multilayer (L2/L3/L4) ACL suite of sophisticated policy-based control mechanisms that enables service providers to deploy easily based on actual network environment needs v
