HOW TO SECURE YOUR NETWORK SWITCHES FROM UNAUTHORIZED ACCESS

Switch detects unauthorized network access

You can use encryption protocols such as SSH, HTTPS, or SNMPv3 to secure the switch's remote access, web interface, or network management, respectively. I configured the switch to fail-open if the communication with CPPM lost, but I got the unauthorized. You can prevent unauthorized users from reconfiguring your switch and viewing configuration information. Networks connect devices to perform essential business functions, making network security critical to defend.

Selection Guide for SFP Optical Network Switches for Local Area Networks

A practical, engineer-friendly guide to choosing the right transceiver form factor by speed, port density, power, migration plan, and operational risk—built for 25G/100G networks in 2026. SFP (Small Form-factor Pluggable) modules are hot-swappable optical or copper transceivers used in switches, routers, firewalls, and network interface cards. Published: 2026 | Category: Network Hardware Knowledge Base / Optical Communications Core Keywords: SFP Module, SFP Transceiver, Small Form Factor Pluggable, What is SFP, SFP vs SFP+ Read Time: Approx. Different SFP modules support different: That's why selecting the correct model matters.

How to use a server rack network cable management system

In this article, you will learn everything about the basics, implementation and benefits of structured cable management in a server rack - including a practical example and the integration of powerful cable management software like Docusnap. Docusnap automatically documents and visualizes cable flows - ideal for efficient, legally compliant IT & network rack cable management. Take note of your servers, switches, and other devices, power distribution units (PDUs) locations, and available rack space to plan clean cable paths that avoid clutter, maintain airflow, and simplify maintenance. Once you understand your current layout, think through how cables will move through. It ensures that different connections between servers, networking equipment, and power sources remain orderly and accessible.

Layer 2 ACL Application of Access Layer Switches

ACLs can be configured to match packets based on Layer 2 MAC, Layer 3 IP or Layer 4 TCP/UDP parameters. We have 3850 switches in our environment which are acting as a layer 2 only with a trunk port configured to the core (6500). Access Control Lists (ACLs) are crucial for enhancing network security, especially on Layer 2 switches configured with extended access lists using source and destination criteria.
