Here is a network topology diagram, a type of schematic that depicts how different network devices, such as routers, switches, and firewalls, are interconnected within a LAN. The diagram includes multiple Cisco switches (C9300-24UXM, C9300-48UXM, C9500) labeled with specific model numbers and IP addresses, indicating their roles and positions within the network, such as distribution frames (DF) and main distribution frame (MDF) core. This detailed mapping is crucial for network administrators to manage, troubleshoot, and plan upgrades for the network's hardware infrastructure.
