Dual Stack Ethernet Switch – Model: DCRS-5650

 Key features

High reliability

1. IEEE  802.1w  Rapid  Spanning  Tree  Protocol  provides  a  loop-free  network  and redundant links to the core network with rapid convergence.
2. IEEE 802.1s Multiple Spanning Tree Protocol runs STP per VLAN base, providing Layer 2 load sharing on redundant links.
3. IEEE 802.3ad Link Aggregation Control Protocol (LACP) increases bandwidth by automatically aggregating several physical links together as a logical trunk and providing load balancing and fault tolerance for uplink connections.„  
4. IGMP  snooping  prevents  flooding  of  IP  multicast  traffic  and  limits  bandwidth intensive video traffic to only the subscribers.

Rich L3 Features

1. The  DCRS-5650  series  switch  delivers  high-performance,  hardware  based  IP routing.
2. RIP v1/v2 and OSPF v2 provide dynamic routing by exchanging routing information with other Layer 3 switches and routers.
3. VRRP prevents your system from failing by dynamically backing up multiple L3 switches for routing.

Comprehensive QoS

1. 8 egress queues per port enable differentiated management of up to 8 traffic types
2. Traffic is prioritized according to 802.1p, DSCP, IP precedence and TCP/UDP port number, giving optimal performance to real-time applications such as voice and video.
3.  Asymmetric bidirectional rate-limiting, per port or per traffic class, preserves network bandwidth and allows maximum control of network resources.

Enhanced Security

1. Port Security ensures access to a switch port based on MAC address.
2. IEEE 802.1X port-based access control ensures all users are authorized before being granted access to the network. User authentication is carried out using any standard-based RADIUS server.
3. Access Control Lists (ACLs) can be used to restrict access to sensitive network resources by denying packets based on source and destination MAC addresses, IP addresses, TCP/UDP ports.
4. SSL, Web Management Encryption, RADIUS and TACACS+ protect data communication and ensure data privacy.
5. Private VLAN isolates edge ports to ensure user privacy

Easy high reliability network

1. MRPP is Multi-layer Ring Protection Protocol. It introduced Layer concept for loop at the basis of traditional loop protect protocol. Each loop layer has multi same level Ethernet loop network. With multi- loop layers, it can achieve quick convergence from core to aggregation.
2. MRPP can get fast recovery for links at different layers. Compared with spanning tree protocol, it has advantages of fast convergence, simple protocol calculation, little system resources cost, clear networking idea and so on, which can improve the reliability of Ethernet network operation.
