The Digital China DCRS-5950 Series switches are Gigabit Ethernet Layer 3 Stand alone switches with 16 SFP Gigabit Ethernet ports plus 8 combo Gigabit Ethernet RJ-45/SFP ports. In addition to 24 Gigabit ports, DCRS-5950-26 also includes dual 10-Gigabit uplink ports.
The DCRS-5950-24/ DCRS-5950-26 is ideal for use in the distribution layer of three-tier networks, provides long distance fiber connections to aggregate access layer switches that are dispersed in different locations. It is also an excellent choice as a core switch for small enterprise networks.

- ^#
Features:
- Performance and Scalability^$With 48Gbps/88Gbps switching capacity, the DCRS-5950-24/DCRS-5950-26 delivers high IPv4 and IPv6 IP routing performance.
- The SFP-based Gigabit ports support various optional Gigabit Ethernet mini GBIC transceivers, available from Digital China, for different distance fiber connections.
- The 10 Gigabit Ethernet connectivity of DCRS-5950-26 is accomplished via a hot-pluggable 10 Gigabit XFP transceiver which supports distance up to 300 meters over multimode fiber and 10 to 40km over single-mode fiber.
- The DCRS-5950-24/DCRS-5950-26 supports both AC and DC power supplies for different environment applications.
- ^#Continuous Availability^$IEEE 802.1w Rapid Spanning Tree Protocol provides a loop-free network and redundant links to the core network with rapid convergence.
- IEEE 802.1s Multiple Spanning Tree Protocol runs STP per VLAN base, providing L2 load sharing on redundant links.
- 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.
- IGMP snooping prevents flooding of IP multicast traffic, and limits bandwidth intensive video traffic to only the subscribers.
- ^#L3 Features^$The DCRS-5950-24/DCRS-5950-26 delivers high-performance, hardware based IP routing.
- RIP v1/v2 and OSPF v2 provide dynamic routing by exchanging routing information with other Layer 3 switches and routers.
- DVMRP, PIM-DM and PIM-SM Multicast Routing Protocols send IP multicast traffic from one subnet to another.
- VRRP prevents your system from failing by dynamically backing up multiple L3 switches for routing.
- ^#Comprehensive QoS^$8 queues per port enable differentiated management of up to 8 traffic types.
- Traffic is prioritized according to IEEE802.1p, DSCP, IP precedence and TCP/UDP port number, giving optimal performance to real-time applications such as voice and video.
- Bi-directional rate-limiting, per port or traffic class, preserves network bandwidth and allows full control of network resources.
- ^#Enhanced Security^$IEEE 802.1X port-based access control and MAC-based access control ensure all users are authorized before being granted access to the network.
- Access Control Lists (ACLs) can be used to restrict access to sensitive network resources by denying packets based on L2/L3/L4 headers information.
- Secure Shell (SSH) encrypts network management information via Telnet providing secure network management.
- RADIUS Authentication enables centralized control of the switch and restricts unauthorized users from altering the configuration of the switch.
