  • Are aggregation switches typically stacked

    Are aggregation switches typically stacked

    A stacking method is a network structure which connects multiple switches together into an aggregate logical unit through stacking modules or interfaces to form one switch with greater reliability and performance than individual ones could achieve on their own. While MLAG and switch stacking enhance redundancy, performance, and operational simplicity, their architectural differences can significantly impact network. Switch stacking allows multiple switches to function as a single unit, controlled by one management interface. This simplifies configuration, monitoring, and redundancy in a network. It is a scalable solution to expand network capacity while not having trouble managing multiple physical devices.


  • Core switches are shut down daily

    Core switches are shut down daily

    Problem: Power outages or sags can cause network equipment to lose power unexpectedly, leading to data loss, corrupted configurations, or network downtime. We have a pair of Dell N3224P-ON switches and today's morning my colleague gave me a task and instructions to remove some unused VLANs. I'm sure I removed the correct VLANs. When I saved the configuration, everything stopped working and now we don't know what to do. We already rebooted both. Abrupt disconnections during network communication may increase the risk of processes entering the 'D state' or applications lingering in the 'CLOSE WAIT' state. Furthermore, frequent restarts might contribute to additional wear and tear on the networking equipment, sparking concerns about the. A network switch failure can disrupt business operations by causing connectivity issues, packet loss, and downtime for connected devices.
