Configuring a factory-fresh or recently wiped Cisco router or switch begins long before you enter security commands or assign IP addresses. In network engineering, the “first step” has two distinct phases: establishing physical out-of-band management access to the hardware, and navigating the initial command-line interface (CLI) boot sequence. Without completing the physical connection and reaching... » read more
Cisco Packet Tracer is a cross-platform network simulation tool designed by Cisco Systems to provide an interactive, risk-free environment for designing, configuring, and troubleshooting computer networks. At its core, the software replicates the behavior of physical networking hardware—including routers, switches, wireless access points, firewalls, and end devices—allowing users to practice networking concepts without purchasing thousands... » read more
For decades, the Cisco Catalyst family has served as the foundational building block of enterprise Local Area Networks (LANs). Originally introduced to transition corporate environments from shared collision hubs to dedicated switched Ethernet, the Catalyst brand has evolved from classic fixed-configuration workhorses into an intelligent, programmable switching portfolio. Modern Catalyst platforms—anchored by the Catalyst 9000... » read more
When building network topologies in Cisco Packet Tracer, configuring router and switch ports is often the first operational task you must perform. In the Cisco Internetwork Operating System (IOS), port parameters—such as IP addresses, subnet masks, descriptions, and administrative power states—cannot be modified from the base console. Instead, they require accessing a specialized sub-configuration level... » read more
Link Layer Discovery Protocol (LLDP) is an IEEE standard (802.1AB) Layer 2 protocol that allows network devices to advertise identity, capabilities, and configuration details to directly connected peers. While Cisco switches historically rely on the proprietary Cisco Discovery Protocol (CDP), multi-vendor enterprise environments—incorporating devices from vendors such as Arista, Juniper, HP, and third-party VoIP manufacturers—require... » read more
If you were auditing your browser add-ons and noticed an entry labeled “Cisco Webex Extension” (or simply “Cisco Web Extension”), you might wonder how it got there, what purpose it serves, and whether it poses any security risk. Many users encounter this add-on unexpectedly after clicking an invitation link for an online meeting or receiving... » read more
Cisco Modeling Labs (CML) is Cisco’s premier network simulation platform, delivering an authentic virtual sandbox powered by real Cisco IOS-XE, NX-OS, IOS-XR, and ASA software images. Whether you are preparing for Cisco certifications like CCNA, CCNP, or CCIE, or testing complex automation scripts against virtual network topologies, CML replaces stacks of noisy physical hardware with... » read more
Whether you are preparing a Cisco Catalyst switch for redeployment in a new branch office, clearing a corrupted configuration in a lab environment, or wiping corporate hardware for secondary market resale, performing a thorough erase is a fundamental networking task. However, “erasing” a Cisco switch is not always as simple as entering a single reset... » read more
Securing modern enterprise networks through traditional IP-based Access Control Lists (ACLs) and VLAN segmentation has become unsustainable. Dynamic workforces, cloud adoption, and mobile endpoints cause IP addresses to fluctuate constantly, resulting in sprawling ACL rule sets, frequent network changes, and elevated operational risk. Cisco TrustSec addresses this challenge by decoupling access control from network topology.... » read more
