Causes of network congestion in core switches
Congestion is often caused by bandwidth limits, overloaded devices, inefficient routing, broadcast storms, misconfigured applications, or sudden traffic spikes. Network congestion occurs when the request for network resources overcomes the available capacity, managing to slower data transmission, packet loss, and delays. This situation is commonly observed in computer networks, such as internet, where multiple devices and applications resist for limited. Network switches play a pivotal role in managing and directing traffic within a network, making them essential components of modern connectivity. So get ready to zoom to the clouds and bask in network speed. 🌤 Disclaimer: There will be no actual driving or cars involved.

Enterprises use DHCP as their core switch
At its core, DHCP is a network management protocol that automates the assignment of IP addresses to devices within a network. In an enterprise environment, where hundreds or even thousands of devices require unique addresses, manual IP address management would be inefficient and error-prone. But a poorly managed DHCP can lead to IP conflicts, downtime, and network chaos. Here's your Admin's Quick Guide to keeping DHCP rock solid. QUESTION Based on best practices for enterprise network design, should the DHCP server be on a different access switch as other end-user devices or can it be placed on an access switch shared by other end-user devices? @Ramblin Tech. Instead of manually assigning IP addresses, subnet masks, default gateways, and DNS server details to every computer, phone, or printer, DHCP handles this automatically, saving time, reducing errors, and ensuring efficient use of network resources. So, how do you make this happen. -SVI are created on core -Vlans are created and access ports are configured with the respective vlans on the access.

Frequent up down of core switch ports
Frequent service switchovers increase load of the device and may result in service data loss. Link flapping protection can solve the problem. You can configure this function to disable an interface that frequently alternates between Up and Down. There are no specific requirements for this document. I have checked many switches that are located in different buildings and these had same kind of logs! the port is going down for like 2 seconds and up again why is this happening? two switches are doing this. Port flapping is a network problem where a port continuously switches on and off (up and down), causing instability. The overwhelming amount of packet loss and increased latency due to this constant rate switching often causes massive degradation in the network performance.
