Network switches SMC

The SMC6152PL2 is a Fast Ethernet Layer 2/4 Power over Ethernet switch featuring 48-ports 10/100Base-TX, 2-ports 1000Base-T (RJ-45) and 2-ports Gigabit combo (RJ-45/SFP). The SFP ports support both 100Base-FX and 1000Base-X. The switch is ideal for Fast Ethernet desktop connectivity and wiring closets to power device such as IP phones, wireless access points and IP cameras.An integrated part of the SMC61xx and SMC81xx switch families is support for IP Clustering, which allows to group up to 32 switches together into a single logical group which can be managed using a single IP address. This switch is a cost-effective solution that is packed with features and brings continuous availability, enhanced security and advanced QoSto the edge of the network, while maintaining simplicity of management.

Performance and Scalability
With 17.6 Gbpsswitching capacity, the SMC6152PL2 delivers non-blocking and wire-speed switching performance on all Fast Ethernet and Gigabit Ethernet ports.The four Gigabit Ethernet combo ports provides flexible choices for uplink copper or fiber uplinks.

High Availability
IEEE 802.1w Rapid 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 802.1s Multiple Spanning Tree Protocol runs STP per VLAN, 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 the subscribers only.Broadcast Storm Control prevents faulty end stations from degrading overall system performance.

Comprehensive QoS
4 egress queues per port enable differentiated management of up to 4 traffic types.Traffic is prioritized according to 802.1p,DSCP, L4 port number and Access control list, giving optimal performance to real-time applications such as voice and video. Asymmetric bi-directional rate-limiting, per port or per traffic class, preserves network bandwidth and allows maximum control of network resources.

Enhanced Security
Port Security ensures secure access to switch ports based on MAC addresses, limits the total number of devices from using a switch port and protects against MAC flooding attacks.
IEEE 802.1x port-based or MAC-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. This is done by hardware, so switching performance is not compromised.
Security Shell (SSH) and Secure Sockets Layer (SSL/HTTPS) encrypt network management information via Telnet and web, providing secure network management.
TACACS+/RADIUS Authentication enables centralized control of the switch and restricts unauthorized users from altering theconfiguration of the switch.
Private VLAN isolates edge ports to ensure user privacy.

Simplified Management
Industry standard Command Line Interface (CLI) via console port or Telnet provides a common user interface and command set for users to manipulate the switch. The embedded user friendly web interface helps users configure switches quickly and simply. Four groups of RMON are supported for traffic management, monitoring 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.

PoEFeatures
SMC6152PL2 can transfer data and power to PoEenabled devices such as VoIP phones, wireless access points and IP surveillance cameras, using existing CAT 5 cables to distances of up to 100 meters. It supports up to 15.4W on 24 ports or 7.5W on 48 ports. The need for individual power sources is eliminated, saving on costs for power cable installation and avoiding power outlet availability issues later.
If the power demand exceeds the switch’s maximum power supply, ports can be prioritized to receive power.
