Dell N3024 Switch Log File ? Help
Hello, there are two dell 3024 (Version 6.3.1.8 ) switches, they are stacked together. I'm getting these logs, the network slows down from time to time. Some ports are closed and opened (Link Up: Gi2/0/2, Link Down: Gi2/0/21) and it takes backup at certain time intervals (Copy of running configuration to backup unit complete). Does anyone have a solution for these? Thank you in advance for your answers.Notice Mar 29 07:33:27 TRAPMGR Spanning Tree Topology Change Received: MSTID: 0 Te1/0/2

Hello, a port can be down or up when there is a topology change on a device with multiple spanning trees configured. It may be normal to see these notifications. If there is edge port usage, I think Portfast can be enabled.
page 772 https://dl.dell.com/manuals/all-products/esuprt_ser_stor_net/esuprt_networking/networking-n1100-series_users-guide_en-us.pdf
Port Fast
The PortFast feature reduces the STP convergence time by allowing edge ports that are connected to end devices (such as a desktop computer, printer, or file server) to transition to the forwarding state without going through the listening and learning states
Hope that helps
