User Manual

Class D and E:

Class D is a class with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used for IP Multicast. See also RFC 1112. Class E is a class with first 4 MSB set to 1-1-1-1 and is used for IP broadcast.

According to IANA (Internet Assigned Numbers Authority), there are three specific IP address blocks reserved and able to be used for extending internal network. We call it Private IP address and list below:

Class A

10.0.0.0 ---

10.255.255.255

Class B

172.16.0.0

---

172.31.255.255

Class C

192.168.0.0 ---

192.168.255.255

Please refer to RFC 1597 and RFC 1466 for more information. Subnet mask:

It means the sub-division of a class-based network or a CIDR block. The subnet is used to determine how to split an IP address to the network prefix and the host address in bitwise basis. It is designed to utilize IP address more efficiently and ease to manage IP network.

For a class B network, 128.1.2.3, it may have a subnet mask 255.255.0.0 in default, in which the first two bytes is with all 1s. This means more than 60 thousands of nodes in flat IP address will be at the same network. It’s too large to manage practically. Now if we divide it into smaller network by extending network prefix from 16 bits to, say 24 bits, that’s using its third byte to subnet this class B network. Now it has a subnet mask 255.255.255.0, in which each bit of the first three bytes is 1. It’s now clear that the first two bytes is used to identify the class B network, the third byte is used to identify the subnet within this class B network and, of course, the last byte is the host number.

Not all IP address is available in the sub-netted network. Two special addresses are reserved. They are the addresses with all zero’s and all one’s host number. For example, an IP address 128.1.2.128, what IP address reserved will be looked like? All 0s mean the network itself, and all 1s mean IP broadcast.

128.1.2.128/25

KGS-2416 specifications

KTI Networks KGS-2416 is a sophisticated Ethernet switch designed to meet the demands of modern networking environments. This device is particularly ideal for enterprises requiring robust performance for an expanding network infrastructure. With 24 10/100/1000Base-T ports and 2 gigabit SFP (Small Form-factor Pluggable) uplink ports, the KGS-2416 provides ample connectivity options suitable for a variety of applications, including servers, workstations, and other network devices.

One of the standout features of the KGS-2416 is its support for Layer 2 switching, which enhances data traffic management by enabling the configuration of VLANs (Virtual Local Area Networks). This capability allows network administrators to segment traffic and improve overall network performance and security. The switch supports IEEE 802.1Q VLAN tagging, allowing for up to 4096 VLANs to be configured, thus ensuring flexible network design and management.

Additionally, the KGS-2416 supports advanced traffic management features such as Quality of Service (QoS). This technology prioritizes critical network traffic, ensuring smooth and uninterrupted service for voice, video, and data applications. With support for multiple QoS standards, administrators can tailor the performance of their networks based on their specific needs.

Power over Ethernet (PoE) capability is another significant feature of the KGS-2416, allowing users to deliver both data and power over a single Ethernet cable to powered devices. This capability simplifies wiring and reduces the need for additional power supplies, making it an ideal solution for deploying IP cameras, wireless access points, and VoIP phones.

The switch is designed with an intuitive user interface that makes configuration and management hassle-free. It can be managed through both web-based GUI and command-line interface (CLI), providing flexibility for various administrative preferences. Moreover, the device supports SNMP (Simple Network Management Protocol), allowing for seamless integration into existing network management systems.

In terms of reliability, the KGS-2416 boasts features like redundant power supply options and a fanless design for silent operation. This makes it a reliable choice for environments where noise and downtime must be minimized. Overall, the KTI Networks KGS-2416 is an excellent choice for organizations looking for a feature-rich, reliable, and efficient Ethernet switch to power their networking needs.
