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.

Rate limiting of core switch ports
Rate-Limiting for all traffic provides a method for limiting the amount of bandwidth a user or device may utilize inbound on a switch port. This effectively sets an inbound usage level on a given port, and is a tool for enforcing maximum service level commitments granted to. This chapter describes how to configure rate limits for supervisor-bound traffic on Cisco NX-OS devices. Rate limits can prevent redirected packets for exceptions from overwhelming the supervisor module on a Cisco NX-OS device. You can configure rate limits in packets per second for the following.
