Outstanding Flexibility and High Performance PLANET CS-6306R Core Layer Routing Switch is specially designed for large network applications such as enterprises, campuses, communities, ISPs and data center networks where flexible configuration, large capacity, high density, high reliability and advanced traffic management are required.    The CS-6306R is the High-density Chassis Ethernet Switch built with 6 module slots and redundant power supply. It provides great porting flexibility for network deployment by offering various combinable management modules and switch modules. For instance, one management module can be collaborated with four switch modules, or two management modules work to mutually perform system backup. Within the 9U height, single chassis, the maximum configuration can be:   192 10/100/1000BASE-T Copper Slots 192 100/1000BASE-SX/LX SFP Fiber Slots 64 10G SFP+ Fiber Slots  16 40G QSFP+ Fiber Slots   Positioned as the core layer switch, the CS-6306R serves ideally for large-sized networks and IP metropolitan networks by supplying advanced intelligent and secure features and giving high performance and flexibility.   Scalable 10-Gigabit and 40-Gigabit Performance The CS-6306R delivers Gigabit, 10-Gigabit and 40-Gigabit Ethernet connectivity in a highly-flexible and resilient modular platform. With high switching capacity, the CS-6306R Chassis Switch supports wire-speed L2/L3 forwarding and high routing performance for IPv4 and IPv6 protocols. The scalable and flexible modular architecture supports up to 3Tbps forwarding performance in a single system. The CS-6306R is ideal for the core layer of campuses, enterprise networks and the aggregation layer of IP metropolitan networks and wide area networks.   Rich Multi-Layer Networking Protocols The CS-6306R comes with the complete Layer 3 managed function with comprehensive protocols and applications to facilitate the rapid service deployment and management for both the traditional L2 and L3 networks. With support for advanced features, including RIP, RIPng, OSPFv2, OSPFv3, BGP, BGP4+ etc., this chassis switch is ideal for the traditional or fully virtualized data center.   Strong Multicast  The CS-6306R supports abundant multicast features. In Layer 2, it features IPv4 IGMPv1/v2/v3 snooping and IPv6 MLD v1/v2 snooping. With Multicast VLAN Register (MVR), multicast receiver/sender control and illegal multicast source detect functions. In Layer 3 multicast protocols, it features PIM-DM, PIM-SM and PIM-SSM which make the CS-6306R great for any robust networking.   Full IPv6 Support  The CS-6306R Chassis Switch supports IPv4-to-IPv6 technologies including IPv4 manual/automatic tunnel, IPv6-to-IPv4 tunnel, and Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) tunnel. It comprehensively supports IPv6 Neighbor Discovery, DHCPv6, Path MTU Discovery, IPv6-based Telnet, SSH and ACL, meeting the need of IPv6 network device management and service control.    High Reliability The key components of the CS-6306R such as management module, power system and the fan system support redundancy design. All system modules support hot-swap and seamless switching without manual intervention.  It supports In-service Software Upgrade (ISSU) and Graceful Restart (GR) for OSPF/BGP routing protocol, guaranteeing the user data non-stop forwarding when the system is upgrading. It supports Bidirectional Forwarding Detection (BFD) that realizes fault detection and service recovery in seconds through linking with Layer 2 or Layer 3 protocol.   Redundant Ring, Fast Recovery for Critical Network Applications The CS-6306R supports redundancy protection mechanism and features strong, rapid self-recovery capability to prevent interruptions and external intrusions. It incorporates Layer 3 Virtual Router Redundancy Protocol (VRRP) protocol, Layer 2 Spanning Tree Protocol IEEE 802.1s MSTP (Multiple Spanning Tree Protocol) technology into customer’s network to enhance system reliability and uptime. In a certain simple Ring network, the recovery time could be less than 50ms to quickly bring the network back to normal operation.   Centralized Hardware Stacking Management Several CS-6306R Chassis Ethernet Switches can be used to build a virtually logical facility. The CS-6306R gives the enterprises, service providers and telecoms flexible control over port density, uplinks and switch stack performance. The CS-6306R can connect as a ring for redundancy and ensures that data integrity is retained even if one switch in the stack fails. You can even hot-swap switches without disrupting the network, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth demands.   Powerful Security from Layer 2 to Layer 4 The CS-6306R offers comprehensive Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical network applications. Its protection mechanism also comprises 802.1x port-based and MAC-based user and device authentication. With the private VLAN function, communication between edge ports can be prevented to ensure user privacy.    Advanced IP Network Protection The CS-6306R also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent from IP snooping attack and discard ARP packets with invalid MAC address. The network administrators can now construct highly-secure corporate networks with considerably less time and effort than before.    Enhanced Quality of Service The CS-6306R Switch fully supports DiffServ module, so users can specify a queue bandwidth on each port.  WRR/SP/SWRR scheduling is also provided. The CS-6306R supports the port security to enable trusted CoS, DSCP, IP precedence and port priority. Users can modify packets’ DSCP and COS values so that the traffic can be classified by port, VLAN, DSCP, IP precedence and ACL table. User can also modify packets’ DSCP and IP precedence values to specify different bandwidths for voice, data and video to customize different qualities of service.    Efficient and Secure Management For efficient management, the CS-6306R is equipped with console, Web and SNMP management interfaces.  With the built-in Web-based management interface, the CS-6306R offers an easy-to-use, platform-independent management and configuration facility.  For text-based management, it can be accessed via Telnet and the console port. For reducing product learning time, the CS-6306R offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new command from these switches For standard-based monitor and management software, it offers SNMPv3 connection which encrypts the packet content at each session for secure remote management. Moreover, the CS-6306R offers secure remote management by supporting SSHv2, TLSv1.0 and SSLv3 connection which encrypts the packet content at each session.   Extractive Power Supply Design to Increase Flexibility The CS-6306R is equipped with one extractive 100~240V AC power supply unit, so it is easy to replace the power for users. Besides, the CS-6306R reserves another two backup power slots on the front panel and users can add the second AC or DC power to the redundant power supply installation. The AC power or DC power is optional. The redundant power system is specifically designed to handle the demands of high-tech facilities requiring the highest power integrity.
