The scalable and flexible modular architecture supports up to 1.47Tbps forwarding performance in a single system. They are 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-6303R 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. It supports advanced routing protocols, including RIP, RIPng, OSPFv2 and OSPFv3.
Strong Multicast
The CS-6303R 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 detection functions can be had. In Layer 3, it features PIM-DM, PIM-SM and PIM-SSM which make it great for any robust networking.
Full IPv6 Support
The CS-6303R 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-6303R are the management module, power system, fan system, and redundant power design. All system modules support hot-swapping and seamless switching without manual intervention.
The CS-6303R supports In-Service Software Upgrade (ISSU) and Graceful Restart (GR) for OSPF and BGP routing protocols, ensuring non-stop user data forwarding during the system is upgraded. It also supports Bidirectional Forwarding Detection (BFD), enabling fault detection and service recovery within seconds by integrating with Layer 2 or Layer 3 protocol.
Redundant Ring, Fast Recovery for Critical Network Applications
The CS-6303R supports a redundancy protection mechanism and feature strong, rapid self-recovery capability to prevent interruptions and external intrusions. It incorporates Layer 3 Virtual Router Redundancy Protocol (VRRP) protocol and 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 simple ring network, the recovery time could be less than 50ms to quickly bring the network back to normal operation.
Centralized Hardware Stacking Management
The CS-6303R can be used to build a virtually logical facility, providing enterprises, service providers, and telecoms with flexible control over port density, uplinks, and switch stack performance. The chassis switch can be connected in a ring for redundancy, ensuring data integrity even if one switch in the stack fails. You can even hot-swap switches without disrupting the network, greatly simplifying the process of upgrading the LAN to meet increasing bandwidth demands.
Powerful Security from Layer 2 to Layer 4
The CS-6303R 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. Their protection mechanism also comprises 802.1x port-based and MAC-based user and device authentication. The private VLAN function prevents communication between edge ports, ensuring user privacy.
Advanced IP Network Protection
The CS-6303R also provides DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection functions to prevent IP snooping attacks and discard ARP packets with invalid MAC addresses. Network administrators can now construct highly-secure corporate networks with considerably less time and effort than before.
Enhanced Quality of Service
The CS-6303R fully supports the DiffServ module, allowing users to specify queue bandwidth on each port. WRR, SP, and SWRR scheduling are also provided. The chassis switch supports port security to enable trusted CoS, DSCP, IP precedence, and port priority. Users can modify packets' DSCP and CoS values so that traffic can be classified by port, VLAN, DSCP, IP precedence, and ACL table. Users can also modify packets' DSCP and IP precedence values to allocate different bandwidths for voice, data, and video, customizing different levels of service quality.
Efficient and Secure Management
For efficient management, the CS-6303R is equipped with console, Web and SNMP management interfaces.
Moreover, the chassis switch offers secure remote management by supporting SSHv2, TLSv1.2 and SSLv3 connection which encrypts the packet content at each session.
Extractive Power Supply Design for Enhanced Flexibility
The CS-6303R is equipped with an extractable 100–240V AC power supply unit, making it easy for users to replace the power module. Additionally, the chassis switch reserves two extra backup power slots on the front panel, allowing users to install a second AC or DC power supply for redundancy. The AC and DC power options are interchangeable. The redundant power system is specifically designed to meet the demands of high-tech facilities requiring maximum power integrity.
