Users Manual of CS-6306R
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 are management module and 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 upgraded. 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) 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 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.
