[. . . ] 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 Carrier Switches Metro Switch 3000 Series with mixed wired and wireless access. The Metro Switch 3000 Series 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 via a Web GUI or command line interface to prevent abnormal or illegal access. The policies can be defined to deny packets based on source and destination MAC addresses, IP addresses or TCP/UDP ports. Carrier Switches Metro Switch 3000 Series Resilient and Redundant Design A quick recovery and round-the-clock network is vital for service providers to establish a robust network. The Metro Switch 3000 Series provides comprehensive features to make sure network is well operated. The IEEE 802. 3ad Link Aggregation feature reduces network downtime by providing redundant paths and bandwidth aggregation to critical connections, while IEEE 802. 1w Rapid Spanning Tree Protocol (RSTP) and IEEE 802. 1s Multiple Spanning Tree Protocol (MSTP) allow immediate recovery from failed connections by sending packets via the backup link. Furthermore, since the Metro Switch 3000 Series supports backup power system, the power is supplied to the switch in case of an unexpected outage. Intelligent Fan Control Algorithm for Power Saving Fans play an important role in energy consumption since it's the key to heat dissipation. The Metro Switch 3000 features auto temperature detection and appropriate fan speeds with the Intelligent Fan Control algorithm based on complex mathematics and physics formulas.
