DCRS-5650-28CT L3 Gigabit Ethernet Switch - 24 x 10/100Base-TX + 2 x Gigabits Combo(SFP/GT) + 2 x 10/100/1000Base-T
DCRS-5650 series switch is L3 fast Ethernet switch which meets the requirements of security and intelligent networks for education institutes, governments, carriers, enterprises, and industries. It can be the access device for large networks, as well as the collective layer device for buildings or core switch for small and medium networks.
High reliability
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 Layer 2 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.
Network protocols
DCRS-5650 series routing switch supports spanning tree, supports 802.1Q, 802.1p, 802.3ad, 802.3x, GVRP, DHCP, SNTP standards, supports IGMP, DVMRP, PIM protocols, supports RIPv1/2 and static routing protocols.
Comprehensive QoS
8 egress queues per port enable differentiated management of up to 8 traffic types
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.
Asymmetric bidirectional rate-limiting, per port or per traffic class, preserves network bandwidth and allows maximum control of network resources.
Enhanced Security
Port Security ensures access to a switch port based on MAC address.
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.
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.
SSL, Web Management Encryption, RADIUS and TACACS+ protect data communication and ensure data privacy.
Private VLAN isolates edge ports to ensure user privacy
Simple Management
Industry standard Command Line Interface (CLI) via console port orTelnet provides a common user interface and command set for users to manipulate the switch.
Embedded user friendly web interface helps users quickly and simply configure switches.
Four groups of RMON are supported.
Backup and restore firmware and configuration files via TFTP.
