One of the technologies used to improve network performance is the separation of large broadcast domains into smaller ones. This article describes how to configure, manage, and troubleshoot VLANs and VLAN trunks. It will also explore security considerations and strategies related to VLANs and trunks, and best practices for VLAN design.
MAC addresses play a crucial role in the data link layer (Layer 2) of the Open Systems Interconnection (OSI) model. MAC addresses are used to send Ethernet frames between two stations in the same local area network. Each station has a unique MAC address that is used to identify who is the sender (source mac address) and who the receiver (destination mac address) is.
TCP keepalive settings play a crucial role in network performance and resource management. By following the best practices and adjusting the settings to suit your specific needs, you can optimize your system’s ability to detect and clean up stale network connections while maintaining optimal performance.
Dynamic Host Configuration Protocol (DHCP) is a standard protocol that allows a server to dynamically distribute IP addressing and configuration information to clients. In the Classless Inter Domain Routing (CIDR) environment of IPv4 the following parameters should be defined on every IPv4 host:: 1. ip addres, 2. subnet mask, 3. default gateway
DHCP relay agent is a small program that relays DHCP/BOOTP messages between clients and servers on different subnets. DHCP/BOOTP relay agents are part of the DHCP and BOOTP standards and function according to the Request for Comments (RFCs), standard documents that describe protocol design and related behavior.
The difference between these two networking devices has been an unsolvable mystery to me for quite some time. For a while, I used to use the words 'bridge' and 'switch' interchangeably. But after getting more into networking, I started noticing that some people tend to see them as rather different devices... So, maybe I've been totally wrong? Maybe saying 'bridge aka switch' is way too inaccurate?
