Performance and Scalability |
 |
With 52Gbps switching capacity, the SMC8126PL2-F delivers wire-speed switching performance on all gigabit ports, allowing users to take full advantage of existing high-performance, gigabit integrated servers, PCs and laptops by significantly improving the responsiveness of applications and file transfer times. |
 |
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 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. |
 |
Comprehensive QoS |
 |
4 egress queues per port enable differentiated management 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. |
 |
IEEE 802.3af PoE Features |
 |
The SMC8126PL2-F supports max. 15.4 Watts per port over existing CAT 5 cables to distances of up to 100 meters. Port one to four can even support up to 31 Watts to power devices such as VoIP phones, wireless access points and surveillance cameras. By using Power over Ethernet the need for individual power sources is eliminated, saving on costs for power cable installation and avoiding power outlet availability issues later on. |
 |
Enhanced Security |
 |
Port Security allows access to switch ports based on MAC addresses, thus limiting the total number of devices using a switch port and protecting 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 the configuration of the switch. |
 |
Private VLAN isolates edge ports to ensure user privacy. |
 |
Simplified Management |
 |
The user friendly web interface helps new users to configure the switch quickly and easily. For advanced users an industry standard Command Line Interface (CLI) via console port or Telnet provides a common user interface and command set to configure the switch. |
 |
Four groups of RMON are supported for traffic management, monitoring and analysis. When upgrading firmware or fine tuning configuration, dual software images and multiple configuration files can be used for backup. TFTP can be used to backup or restore firmware and configuration file. |
