4. Functional Description

4.1 PHY Monitoring and Port Mode Set-up

It is a major task of the software to continuously monitor the PHYs in order to set up the switch ports according to whether the link is down or up and in the latter case what the current speed, duplex mode and pause capabilities are.

PHYs are being polled every 100 ms.

4.2 Flow Control

In the 24-port switch flow control (back pressure) is also supported in half duplex. Flow control can be enabled or disabled on a per-port basis from the command line interface.

If flow control is enabled for a port the associated PHY will be set to advertise support of Symmetric Pause, but not Asymmetric Pause. If the station connected to the port also supports Symmetric Pause, flow control will be enabled on the switch port.

4.3 Ageing

To prevent that an automatically learned MAC address of a station that has been detached will remain in the MAC address table permanently, the ageing function in the switch is activated on a regular basis. The period for doing the ageing function is determined by the ageing time parameter. The ageing time parameter can be set from the command line interface. Default value is 300 seconds. Setting the ageing time parameter to 0 disables the ageing function.

4.4 VLAN

The device supports 802.1Q tag based VLAN. With tagging to the header of packets, the network can be segmented in groups to reduce the collisions from widely broadcasting. A maximum of 24 VLAN groups can be stored in EEPROM. The VLAN look up is based on full 24-bit vlaue of packet VID or Port PVID. It also provides egress tagging mode setting for each port.

4.5 Link Aggregation

Link aggregation groups (or channels) can be defined statically. LACP (Link Aggregation Control Protocol) is not supported.

Maximum number of aggregation groups is 8.

The software will automatically detect that a link has gone down and then reassign packet distribution on the other links in the group.

4.6 Quality of Service

Various classifications and prioritization such as TOS, Egress rate control, Ingress rate control and Storm are supported in order to enable Quality of Service for real time applications such as VoIP (Voice over IP).

KGS-2401 specifications

KTI Networks KGS-2401 is a sophisticated gigabit Ethernet switch designed for seamless data distribution in various networking environments. Catering to businesses and workgroups, this switch is built to enhance connectivity, ensuring high performance and reliability.

One of the main features of the KGS-2401 is its 24 Gigabit Ethernet ports, enabling robust data transfer rates of up to 1 Gbps per port. This high throughput is essential for demanding applications such as video streaming, large file transfers, and real-time communications. The switch supports auto-MDI/MDI-X on all ports, simplifying network setup by eliminating the need for crossover cables.

The KGS-2401 employs Store-and-Forward switching technology, which ensures that it only forwards error-free frames to the network. This feature minimizes the chance of collisions and optimizes bandwidth utilization. The switch is equipped with a non-blocking architecture, allowing for the full bandwidth capacity to be utilized on all ports simultaneously, thereby avoiding bottlenecks that can degrade performance.

Another key characteristic is the KGS-2401’s support for Quality of Service (QoS). This allows administrators to prioritize different types of traffic, enhancing the quality of voice and video transmission. By managing data packets, businesses can ensure that critical applications receive the necessary bandwidth while maintaining overall network efficiency.

The KGS-2401 also features extended Layer 2 management capabilities, which include VLAN support and port mirroring. Virtual Local Area Networks facilitate network segmentation, improving security and performance by isolating broadcast domains. Port mirroring is valuable for network monitoring and troubleshooting, providing insights into traffic patterns and potential issues.

On the power front, the KGS-2401 is designed with energy efficiency in mind. It incorporates features like Energy-Efficient Ethernet (IEEE 802.3az) to reduce power consumption during low traffic periods. This not only lowers operational costs but also supports environmentally friendly practices.

In summary, the KTI Networks KGS-2401 is a powerful and flexible gigabit Ethernet switch suited for various networking needs. Its high port density, advanced management features, and commitment to energy efficiency make it an ideal choice for organizations aiming to enhance their network infrastructure while maintaining cost-effectiveness and performance.
