In this tutorial we will Learn how to configure verify and troubleshoot LACP (Link Aggregation or Ether Channel). Actually Link Aggregation or Ether Channel is a technology very similar to PAgP which allows two or more than two physical ports to combine and provide a new third single logical port which results in high availability and increased bandwidth. In below topology diagram you can see two switches switch0 and switch1 having ports fa0/1 and fa0/2.Using LACP we can bind these two ports to form a single logical port.

In this tutorial we will learn about PAGP.We will learn how to configure PAGP and how to verify and troubleshoot it after configuration. But before that we must know what PAGP is.PAgP is actually a Cisco Proprietary Protocol which is known as Port Aggregation Protocol which is used to combine two or more physical ports in to a single logical port or you can say it as a EtherChannel.

Here in this lab we will learn how to block or allow certain services binded on port.In other way you can that how to block or allow certain port or certain services using extended access-list in cisco packet tracer.This is an example lab showing how to block a certain port and how to allow a certain port using extended ACL.In this lab i am going to allow web services port say port number 80 and going to block FTP services say PORT 22. (more…)

Extended ACL is more precise than standard ACL.Even we can block a particular ip or range of ip address or network address using extended acl. We can also allow certain hosts and block few as per our requirement using extended acl. Standard ACL is very light weight and hence consume less processing power while extended need more processing power.Here in this lab we will learn to configure and use Extended access-list using an example lab in cisco packet tracer.We will block our clients or a network to access certain servers and allow to access few servers.
We want to block all clients in network 22.214.171.124/8 to access server SERVER 0 and SERVER1 but can access SERVER2 and SERVER3
STEP 1:First Assign ip address to all as I have mentioned in above Diagram.

In this lab we will learn to configure multi area ospf using cisco packet tracer.
In below Network Topology Diagram you can see there are Two area Area 0 and Area 1.
Now you have to configure OSPF such that devices in area 0 can easily communicate with devices in Area 1
