Overview In this lab, we will be configuring EtherChannels between Cisco catalyst switches. EtherChannel is a port link aggregation technology where multiple physical ports are grouped into one logical link to provide for fault-tolerance, high-speed links and redundancy as well… Continue Reading
Overview In this lab, we are going to show how to integrate Cisco ISE with Microsoft Active Directory. The enterprise network of today is rapidly growing and employees are no longer using only work computers to access internal resources. The… Continue Reading
Introduction In this lab, we are going to be configuring VRRP on the two Distribution Layer switches. Virtual Router Redundancy Protocol is an open standard protocol that is used to provide redundancy in a network. It is a network layer… Continue Reading
Introduction Short for IP Security, IPSec is an Internet Engineering Taskforce (IETF) standard suite of protocols between 2 communication points across an IP network that provides data authentication, integrity, and confidentiality. It is supported by different vendors. OpenSSL can still… Continue Reading
Introduction Cisco’s Generic Routing Encapsulation (GRE) protocol is a tunneling protocol that can encapsulate a variety of network layer protocols between two point-to-point links. GRE can allow you to create an overlay network on top of the existing underlay network… Continue Reading
Introduction In this lab we are going to be Configuring Access Control Lists. IP Access Control lists perform packet filtering to control the movement of packet through a network. In this case, proper rules need to be configured based on… Continue Reading
Introduction In this lab, we are going to go over the basics of git. Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. Git… Continue Reading
In this lab, we are going to use a python script to filter out public IPs from a list of IP addresses. Let’s review a simple IP addressing concept. To conserve IPv4 addresses certain blocks of IPs have been curved… Continue Reading
In this tutorial, we will Using Python script to calculate Network ID. Let’s look at how to write a simple Python script to calculate the Net-ID given an IP address and a subnet mask.We will work with 10.10.10.65/26. This is… Continue Reading
Introduction Another way of configuring inter-VLAN routing is through the use of Switch Virtual Interfaces on a multilayer switch whereby we configure virtual interfaces on the switch. However, we will not require a Router to route traffic between multiple vlans.… Continue Reading
