Core Switch Virtual Interfaces
A Switch Virtual Interface (SVI) is a logical Layer 3 interface configured on a multilayer switch to enable inter-VLAN routing. It allows devices in different VLANs to communicate with each other without using an external router. Understanding how to configure VLANs (Virtual Local Area Networks) and SVIs (Switched Virtual Interfaces) on Cisco switches is crucial for network engineers aiming to optimize security and efficiency in their network infrastructure.

Configuration of Security Ports on Core Switches
Step 1: Enter interface configuration mode Step 2: Configure the port as an access port (required for port security) Step 3: Enable port security Step 4: Set maximum number of secure MAC. If you try to set the maximum value to a number less than the number of secure addresses already configured on an interface, the command is rejected. Learn how to configure port security on Cisco switches to prevent unauthorized network access and pass your CCNA 200-301 exam. In MAC-flooding, an attacker can connect a laptop into an empty Switch port or empty RJ45 wall socket, and he can use hacking tools to generate millions.

A suitable number of devices connected to the core switch
Environments with fewer than 50 connected devices typically do not generate enough internal traffic to justify enterprise core hardware, and a robust router with managed access switches is sufficient. This white paper introduces the following three types of network switches and further discusses the selection criteria for each switch. For a network with over 100 computers, a core switch is indispensable for ensuring stability and high performance. A core switch is a high-capacity, high-performance primary switch installed at the backbone or physical core of a layered hierarchical network.
