High Performance and architecture
The SNS-MR2228N-4C DC/EX switch provides wire-speed switching fabric capacity of 12.8 Gbps, on all gigabit ports, allowing users to take full advantage of existing high-performance, gigabit integrated Servers, by significantly improving the responsiveness of applications and file transfer times. The SNS-MR2228N-4C DC/EX 4C is providing four Gigabit Ethernet ports with flexible uplink, interface.
Enhanced Security Features
The SNS-MR2228N-4C DC/EX switch provide enhanced security by using multiple mechanism to protect network. Port Security ensures access to switch ports based on MAC address limits the total number of devices from using a switch port and protects against MAC flooding attacks. Security Shell (SSH) and Secure Sockets Layer (SSL/HTTPS) encrypt network management information via Telnet and web, providing secure network management. Terminal Access Controller Access Control System (TACACS+) or Remote Access Dial-In User Service (RADIUS) Authentication enables centralized control of the switch and restricts unauthorized users from altering the configuration of the switch. IEEE 802.1x port-based or MAC-based access control ensures that all users are authorized before being granted access to the network. User authentication is carried out using any standard-based RADIUS server. The SNS-MR2228N-4C DC/EX switch offers Private VLAN isolated edge ports to ensure user privacy.
Comprehensive QOS and Rate Limiting
Four hardware queues per port to enable comprehensive L2/4 QOS: Rate Limiting TCP/UDP, Priority Queue Scheduling and Priority Queue Scheduling of up to 4 traffic types. Traffic is prioritized according to 802.1p and DSCP, 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 allowing maximum control of network resources.
Network Availability
With IEEE 802.1s Multiple Spanning Tree Protocol, IEEE 802.1w Rapid Spanning Tree Protocol and IEEE 802.1d Spanning Tree Protocol provides a loop-free network and redundant links to the core network with rapid convergence, to ensure faster recovery from failed links, enhancing overall network stability and reliability. 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. Broadcast Storm Control prevents faulty end stations from degrading overall system performance. The SNS-MR2228N-4C DC/EX also provides redundant power supplies to enable simultaneous connections to independent power sources to ensure system reliability. In addition the SNS-MR2228N-4C DC/EX DC/EX Switch provides two DC power supply circuits -48DC: (-36 to -72VDC).
Complete variety of optical links Using SFP
The SNS-MR2228N-4C DC/EX switch provides complete variety of optical links using 100FX /1000FX SFP for both single mode and multi mode SFP. The SNS-MR2228N-4C DC/EX is ideally for applications where security and reliability required. The switch uses SFP transceivers for connections, providing the flexibility of running any mix of 100BASE-FX /1000BASE-FX multimode fiber up to 1.2 miles or single-mode fiber up to 120Km, respectively for cost-effective enterprise network solutions.
Comprehensive Management
The SNS-MR2228N-4C DC/EX switch with Industry standard Command Line Interface (CLI) via Telnet or console port 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. The switch can be managed and monitored using SNMP and Four groups of RMON for traffic and analysis. When upgrading firmware or fine tuning configuration, the dual software images and multiple configuration files can be used for backup. TFTP can be used to backup or restore firmware and configuration files.
Virtual IP Stacking Architecture
The new generation virtual IP stacking allows connecting up to 36 units of SNS-MR2228N-4C DC/EX or up to 1008 ports into a single entity with single IP address. By using IP clustering and communicate directly with the commander switch, you could manage the remote side from the management station via single IP address.
