  • [ACP-DC Training#11] Loop Prevention and LAG Implementation

    Data center design involves multiple layers of redundancy, extending from server NIC cards to uplinks and switches. While this redundancy is essential, it simultaneously increases the risk of network loops, broadcast storms, and network outages. Today, we will learn key technologies to prevent these risks and build high-performance, redundant L2 data centers. 1. Structure of a Collapsed Core L2 Data Center A data center is…

  • [ACSA Education #28] MSTP Theory and Regional Structure

    A Common Spanning Tree (CST) defines a single Spanning Tree Instance for the entire network, regardless of the number of VLANs. All BPDUs use Untagged VLAN 1, so VLAN details are not considered. Additionally, due to the absence of load balancing, specifying alternative paths or achieving low line usage and potential performance degradation…

  • [ACSA Training #25] Spanning Tree Protocol

    Last time, while discussing network redundancy, we also talked about loops that can occur as a result. As an alternative, I briefly mentioned STP (Spanning Tree Protocol). Today, let's take a closer look at Spanning Tree Protocol. STP (Spanning Tree Protocol) Overview: IEEE 802.1d, the standard version of STP (Spanning Tree Protocol), [addresses] redundant environments…
