WEB CONFIGURATION

QOS Settings

QoS (Quality of Service) is a mechanism which is used to prioritize certain traffic as it is moves through the switch. Traffic can be classified as High or Normal priority and, when the switch is heavily loaded, it is the Normal priority packets that are dropped first. You can select how traffic is prioritized by using one of the four QoS modes which is selected using the QoS Mode drop-down list.

Note: Only one QoS mode can be active at one time. It is not possible, for example, to prioritise traffic using the IP Port number and 802.1p tag.

QoS Disabled

QoS is turned off and all packets have equal priority.

802.1p

Packets are prioritzed using the content of the VLAN-tag. The 802.1p field is held within the VLAN-tag of a packet. The field is three bits long so can hold eight values; 0 - 7 inclusive. When QoS Mode is set to 802.1p, the 802.1p Configuration table appears which allows a priority (normal or high) to be set for each of the eight values.

You can use the Prioritize Traffic drop-down list to quickly set the values in the 802.1p Configuration table. Select All Normal Priority to set all values to normal priority or select All High Priority to set all values to high priority. Use Custom if you want to set each value individually.

Note: Because end-stations, like PCs, are not usually VLAN aware, they do not create VLAN-tagged frames. As a result, this method of prioritization is not ideal when there are a lot of PCs connected to the Switch.

IP Port

Although this is a layer 2 switch, it is capable to looking far enough into each packet to find the port number associated with a UDP/IP or TCP/IP transfer. When QoS Mode is set to IP Port, the Custom QoS TCP/IP

SMCGS24-Smart, SMCGS16-Smart specifications

SMC Networks has been a reliable player in the networking market, and its SMCGS16-Smart and SMCGS24-Smart switches are prime examples of the company's commitment to providing innovative solutions for both small and medium-sized enterprises and larger networks.

The SMCGS16-Smart is a 16-port Gigabit Ethernet switch, while the SMCGS24-Smart expands that offering with 24 ports. Both switches are designed with versatility and performance in mind, making them suitable for various applications, including data centers, campus networks, and office environments.

One of the standout features of the SMCGS16-Smart and SMCGS24-Smart is their support for advanced Layer 2 functionalities. These smart switches facilitate traffic management via VLAN (Virtual Local Area Network) for effective segmentation of network traffic. This capability enhances network security and optimizes performance by isolating broadcast traffic and reducing congestion.

Their Quality of Service (QoS) features enable prioritization of traffic, ensuring that latency-sensitive applications, such as VoIP or video conferencing, receive the necessary bandwidth and low delay for optimal performance. Additionally, both switches support Link Aggregation Control Protocol (LACP), allowing multiple ports to work together for increased bandwidth and redundancy, which is crucial for high-availability environments.

Power over Ethernet (PoE) is another significant advantage of the SMCGS series. The switches deliver power to connected devices like IP cameras, access points, and VoIP phones, simplifying installation and reducing the need for additional power sources. This capability not only saves on installation costs but also enables greater flexibility in device placement.

The user-friendly web management interface allows for easy configuration and monitoring of the switches' performance. It offers essential features like port mirroring and traffic monitoring, making it easier for IT administrators to troubleshoot and manage the network effectively.

Both switches come with a robust metal housing for enhanced durability and heat dissipation, ensuring reliable operation in various environments. This reliability, combined with their advanced features, makes the SMCGS16-Smart and SMCGS24-Smart valuable assets for any organization aiming to build a strong and efficient network infrastructure. SMC Networks has effectively positioned these switches as a solution for businesses seeking high performance, manageability, and scalability in their networking equipment.
