Auto-MDIX Cisco: Unlock Instant Network Setup and Slash Downtime in 2025
The workstation computer or laptop port in networking is called MDI (Media Dependent Interface). In contrast, the ports on network switches are labeled MDIX (Media Dependent Interface with Crossover). This distinction is crucial in ensuring seamless communication. RJ45 jacks, the connectors attached to copper twisted pair cables, are intricately crimped to facilitate communication. The transmit...
Mastering Duplex and Speed Settings for Ethernet Switches in 2025
Duplex and Speed settings are the most basic settings for each switch port. By default, Cisco switches will auto-negotiate the speed and duplex settings. However, the switch port and connected devices, such as a computer or another switch, can mismatch the duplex and speed settings. Two types of duplex settings are used for communications on an...
Master Memory Buffering on Cisco Switch: Techniques for 2026 Networks
Ethernet switches employ memory buffering to manage data traffic efficiently, ensuring frames (data units) are temporarily stored when destination ports face congestion. Effective buffering is crucial to prevent frame loss, which can degrade network performance, increase latency, and trigger retransmissions, ultimately impacting user experience and reliability. This article explores buffering methods, their evolution, and their...
Switching Fundamentals – Everything to Know
An Ethernet switch is a Layer 2 device. Therefore, the switch uses MAC addresses for switching decisions. It is unaware of the protocol being carried in the data portion of the frame, such as an IPv4 packet. The Ethernet hub repeats bits out of all ports except the incoming port, but an Ethernet switch consults...
