Syslog Server implementation for Cisco network devices
On Cisco networking devices, a syslog server refers to a system or application that collects, stores, and manages log messages generated by the Cisco devices. These log messages contain valuable information about the operation, performance, and events occurring on the network equipment. The syslog server helps network administrators and engineers to monitor, troubleshoot, and analyze […]
What is HSRP protocol? How to implement on the network?
HSRP, or the Hot Standby Router Protocol, is a Cisco proprietary protocol that enables two or more routers to work together in a group to present the illusion of a single virtual router to hosts on a LAN. The main purpose of HSRP is to establish network redundancy and avoid single points of failure, thus […]
What is EIGRP Protocol? How to use EIGRP?
EIGRP, which stands for Enhanced Interior Gateway Routing Protocol, is a dynamic routing protocol used in computer networks to help routers exchange routing information efficiently. It was developed by Cisco Systems and is primarily designed for use in IP networks, including both local area networks (LANs) and wide area networks (WANs). EIGRP is an advanced […]

What is a network port? Well known ports and registered ports.
A network port is a communication endpoint in a network. It is identified by a numerical value, called a port number, which helps direct network traffic to specific applications or services running on a device. Ports allow multiple applications to coexist on the same network device by assigning unique port numbers to each application. There […]
Cisco WLAN Controller with VLANs through multiple SSIDs
Let’s start configuring our VLANs and ports. We will create 3 VLANs on SW1 core switch. One of them will serve as Management subnet, others will serve as Office and Guest networks. Upon completion of VLAN and port configurations, we will start configuring Cisco Wireless Controllers and our Cisco Access Points. Both access points will […]
What is Etherchannel ? How to use it?
EtherChannel is a technology used in networking to create a logical link aggregation or link bundling of multiple physical Ethernet links into a single logical link, providing increased bandwidth, improved redundancy, and load balancing across the bundled links. It is also known as Link Aggregation, Port Channel, or Port Aggregation. EtherChannel is typically used in […]
