Can a loop cause the core switch to lose network connectivity
If not properly managed, loops can cause network congestion, broadcast storms, and significant disruptions, leading to a complete network outage. Preventing loops is essential for maintaining network stability and performance. Loops may manifest. A Network Loop happens when there are multiple active Layer 2 paths between switches with no mechanism to block redundant links. Layer 2 switches forward frames based on MAC address tables, but they do not include any Time To Live value like IP packets do. If left unresolved, network loops can disrupt communication, slow down network performance, and even crash switches or. Switching loops occur when network switches are connected together in such a way that network traffic loops around infinitely instead of traversing the hops needed to travel from source to destination. They can take down an entire network.

Core switch stack cannot be switched
This guide explains the symptoms, common causes, Cisco CLI checks, and a verification workflow. basically after you have configured the stack, you can manage it as if it were a single device, as you can read form the document, both devices are responsible for traffic forwarding (Data Plane), but only the Master switch manages the control plane You can configure the stack as L2 or L3 device. We're going to install two 48 port SFP+ switches at a co-location facility that will house all of our primary servers and storage. Our provider will add our 10 gig ring to our rack and normally they handoff one 10gig fiber to us. The only thing plugged into the switch are the uplinks to the core. They require a strategy to prevent this sort of disruption from occurring again.

Does an AP need a core switch
While access switches focus on providing connectivity to end devices, core switches play a critical role in ensuring efficient and reliable data transfer across the network. A core switch is a high-capacity, high-performance Layer 3 switch positioned at the physical backbone of an enterprise network. Engineered to aggregate massive volumes of data from distribution switches, it provides ultra-low latency and maximum throughput to ensure uninterrupted routing and packet. Can you plug an access point into your core switch? Technically yes. but should you? Most networks are designed using 2 or 3 layers. The primary transmission and routing of data signals take place at the core layer only.
