Network Topology Types
Network topology can be defined as the layout pattern and connectivity scheme between the devices in a network. It is simply the layout of network communication. There are two main types of Network topology, and they are Physical and Logical Network topology. Physical Network Topology: Physical topology is the actual connectivity or layout according to real cabling & connections Logical Network…

Port Security
Layer-2 Port Security is used for network traffic control. It allows only the authorized user or filtered MAC address configured to gain access to the network. Enabling mode Pass/Secret in Port Security To enable mode Pass/Secret we have to Secure the Privileged Mode Access. An encrypted Password is recommended (enable secret) Example of How to Enable mode Pass/Secret Below is an example of…

ACL (Access Control List)
ACL (Access Control List)
ACL (Access Control List) is a list of rules that specifies which users or systems are allowed access to a particular object or system resource. It can simply be defined as a set of instructions to filter inbound and outbound traffic on an interface. Access Control List Overview and Access List Concepts Access Control List carries out a packet identification mechanism and can also identify…

Firewalls and VPNs
Firewalls are network security devices that monitor and control incoming traffic and outgoing traffic based on a pre-defined set of rules, while VPNs (Virtual Private Networks) are security services that allow devices to access the internet as if they were connected to a private network. Firewalls and VPNs (Virtual Private Networks) in general are both used for security purposes on the…

STP (Spanning Tree Protocol)
STP (Spanning Tree Protocol)
STP (Spanning Tree Protocol) is a Layer-2 protocol that builds a loop-free network topology. Only one active path can exist between two stations in order for them to function properly. STP is a Network Protocol (Layer2) and has a Standard of IEEE 802.1D/W/S/Q, Cisco (Def on Cisco=PVST). Its function is to prevent Layer2 Loops within a network topology, adapt to network changes and failures. The…

EIGRP Protocol
EIGRP (Enhanced Interior Gateway Routing) Protocol is a dynamic routing protocol for IP networks. It is considered a hybrid protocol type that supports a classless routing technique and uses the Diffusing Update Algorithm (DUAL) to help improve protocol efficiency and routing calculations. EIGRP was designed as a Cisco proprietary protocol for Cisco routers and uses composite metrics (BW, Load,…

Wireless WiFi Roaming
Understanding wireless & WiFi Roaming is very important in WLAN and WiFi computer networking. It occurs when a wireless client moves around in a region with many access points (APs). It may switch automatically to another access point (AP) with more preferred signal strength. Understanding Wireless Roaming Types The wireless roaming types are: Intra-Controller roaming, Roaming between…
