,Extralink Chiron - gigabit switch with SFP ports Extralink Chiron is a 24-port next-generation Layer 3 switch. It targets IP MAN (metropolitan area network), government and corporate networks, Internet cafes. It is developed on the basis of high-performance hardware and supports features such as efficient ACLs, flexible QinQ, 1:1 or N:1 VLAN switching, Ethernet OAM, carrier-level QoS and industry-level 10GE Ether-ring. It also supports Layer 3 routing protocol. High reliability Based on an advanced distribution mechanism and an efficient cross-physical link aggregation function, the logic control plane, service control plane and service data plane are separated. This allows Extralink Chiron to support continuous routing redirection at Layer 3, avoiding service interruption due to a single failure. Telecommunications level Ethernet switch Chiron supports telecom-level Ethernet protection protocol with less than 50 ms protection offset time, STP/RSTP/MSTP, active and backup uplinks, and LACP link aggregation to ensure high service reliability. Provides an excellent Ethernet OAM mechanism for real-time network health monitoring for rapid problem localization and detection. Supports In-Service Software Upgrade (ISSU) to ensure uninterrupted data transfer during system upgrades. Supports various L2 multicast functions, including IGMP-Snooping, fast-leave and trans-vlan. Excellent security mechanisms The advanced hardware infrastructure design implements tier-based packet scheduling and packet protection, prevents DoS-/TCP attacks related to SYN flood, UDP flood, broadcast storm or heavy traffic, and supports tier-based command-line protection, giving different levels of users different management privileges.,Extralink Chiron Switch 24x RJ45 1000Mb/s, 4x SFP+, L3, managed.
