Can loops occur in core switches
If switches work in the core layer, it could bring the entire network down. 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. you can enable route guard to minimize the issue : https://www. com/c/en/us/support/docs/lan-switching/spanning-tree-protocol/10588-74. html 09-09-2021 04:33 PM Generally. A network loop occurs when redundant connections between switches cause data packets to endlessly circulate, suitable to broadcast storms, high CPU usage, and network congestion. When a switch port is accidentally looped back via a cable or connected improperly, the loop can flood the network with broadcast traffic, degrade performance, and even cause a complete outage. To avoid this situation, you can use backup links. A switching Loop creates many performance-related issues. While redundancy is good for network reliability, it can cause serious problems if not managed correctly.

Is the OLT a core switch
The short answer: an OLT is neither a traditional switch nor a router, but it incorporates functionalities of both, along with some unique roles specific to fiber access networks. An Optical Line Terminal (OLT) is a crucial piece of equipment in Fiber to the Home (FTTH) networks, commonly found in Passive Optical Networks (PONs). It acts as the central point of control and connection between the fiber-optic network and the broader telecommunications infrastructure. Let's discuss each one separately: 1. Below is a detailed breakdown: OLT is the core device in PON (Passive Optical Network) systems, connecting. The OLT is responsible for sending downstream data to multiple Optical Network Units (ONUs) or Optical Network Terminals (ONTs) at the user's premises, as well as receiving upstream data from them. Unlike traditional networking devices that operate purely on electrical signals, the OLT deals with.
