GLOSSARY

Access Control List (ACL)

ACLs can limit network traffic and restrict access to certain users or devices by checking each packet for certain IP or MAC (i.e., Layer 2) information.

Boot Protocol (BOOTP)

BOOTP is used to provide bootup information for network devices, including IP address information, the address of the TFTP server that contains the devices system files, and the name of the boot file.

Class of Service (CoS)

CoS is supported by prioritizing packets based on the required level of service, and then placing them in the appropriate output queue. Data is transmitted from the queues using weighted round-robin service to enforce priority service and prevent blockage of lower-level queues. Priority may be set according to the port default, the packet’s priority bit (in the VLAN tag), TCP/UDP port number, IP Precedence bit, or DSCP priority bit.

Differentiated Services Code Point Service (DSCP)

DSCP uses a six-bit tag to provide for up to 64 different forwarding behaviors. Based on network policies, different kinds of traffic can be marked for different kinds of forwarding. The DSCP bits are mapped to the Class of Service categories, and then into the output queues.

Domain Name Service (DNS)

A system used for translating host names for network nodes into IP addresses.

SMC6752AL2 specifications

The SMC Networks SMC6752AL2 is a robust and versatile gigabit Ethernet switch designed to cater to the demands of medium to large enterprise networks. This switch delivers an impressive combination of performance, flexibility, and manageability, making it an ideal solution for businesses seeking to enhance their network infrastructure.

One of the standout features of the SMC6752AL2 is its 48 Gigabit Ethernet ports, allowing for high-speed network connections to a variety of devices such as servers, workstations, and other networked equipment. Additionally, the switch includes 4 SFP (Small Form-factor Pluggable) slots that provide options for connecting to other networking devices via fiber optics, enhancing the versatility of the network configuration.

The SMC6752AL2 supports advanced Layer 2 switching capabilities, which are crucial for efficient data handling and traffic management. With features such as VLAN (Virtual Local Area Network) support, the switch can segment network traffic to improve performance and security while effectively managing broadcast domains. It supports 802.1Q VLAN tagging, allowing for better network segmentation and isolation of different types of traffic.

Moreover, the switch is equipped with Quality of Service (QoS) features to prioritize critical data transmissions. This is essential for applications requiring real-time data flow, such as VoIP (Voice over Internet Protocol) and video conferencing. The SMC6752AL2's QoS capabilities enable users to classify and prioritize traffic, ensuring a smooth and seamless experience for bandwidth-intensive applications.

The SMC6752AL2 also includes features such as port mirroring and link aggregation, enhancing the monitoring and management capabilities of the network. Port mirroring allows administrators to duplicate traffic from one port to another for analysis and troubleshooting, while link aggregation enables combining multiple connections for increased bandwidth and redundancy.

In terms of security, the switch supports802.1X port-based authentication, providing a layer of network access control that ensures only authorized users can connect. This feature, combined with the ability to create access control lists (ACLs), helps to safeguard the network against unauthorized access and other potential threats.

Overall, the SMC Networks SMC6752AL2 is a feature-rich Ethernet switch that offers reliable performance and advanced capabilities for managing enterprise networks. Its combination of port density, layer 2 switching features, QoS functionalities, and enhanced security makes it an excellent choice for organizations looking to expand or upgrade their networking solutions. With the SMC6752AL2, businesses can maintain high-performance connectivity and effective network management tailored to their specific operational needs.
