…..And we’re back again!

Doesn’t it feel good to be back online? Up and running!?

     Ok maybe not running, I’m not too athletic.
Technically….people would classify me as a couch potato. Hiding behind my computer, creating packet tracers for your enjoyment!


Speaking of packet tracers! I’ve got another one for you! Wanna see it? Well here it is! In all it’s glory! Click here to download Packet tracer Activity!


ACLS

  

This time it’s ACCESS CONTROL LISTS with PORT SECURITY!(Switches) I also threw in there some lightly fried fish fillets.

Just kidding, I threw in some Eigrp! HA!

     AGAIN, the configurations are easy. Nothing too robust. I keep everything at a basic level for those of you looking to obtain your CCENT/CCNA R&S.

     In the coming weeks I will be getting a bit more involved and moving slightly to more “Medium” level lab’s. Some of the labs will look familiar to you, and they WILL be! Most will be the same configurations/set up as the previous labs BUT with a twist. TROUBLESHOOTING techniques! MUWaaHAaHahhAhahaaaa

In order to be able to complete this lab, you’re going to need to know about:


ACL’s
Introduction to Access Lists
Configuring an ACL on a Cisco switch
Standard Access List (ACL) for the Cisco CCNA – Part 1


EIGRP
Routing & Switching, VLAN, EIGRP, IPv4, DHCP 
Learn EIGRP for the Cisco CCNA – Part 1
6.2.2.5 Lab – Configuring Basic EIGRP for IPv4
  

PORT SECURITY
Cisco Switch Port Security Packet Tracer Demonstration – Part 1
How to Configure Port Security on a Cisco Switch

 

BASIC CONFIGURATIONS
1.1.4.6 Lab – Configuring Basic Router Settings with IOS CLI 

It would also help to know the difference between VLANS and ACLS.
What is a VLAN?
VLAN vs ACL in CISCO routing

 

Good luck and have fun!

Are you ready to eat that Elephant! ARE YOU HUNGRY!?

If you haven’t already, take a look at the previous blog.

~How do you eat an Elephant~

Let’s eat!

This Lab is not difficult if you know basic Vlans, DHCP, and OSPF.
No hard confusing configurations. Just plain, regular …….stuff.
 It can become overwhelming if you don’t have the basics down.

Part 2 “Intruder Alert!”

ospf2     We did a lot of work yesterday trying to fix the network. The Information Security Specialist at the county sheriff’s office informed us that the intruders got into the network by “TELNET”

 Unfortunately, our previous network engineer didn’t use SSH also known as (secure shell) and we have been open to the internet for some time! I guess it was only a matter of time until someone infiltrated us? As network engineers, make sure you LOCK IT DOWN with passwords, logins, and encryptions. Another way to help secure your networks are by using firewalls, ACL’s, restrict ports, and physical connections.

Lab – Configuring OSPF PART 1

INTRUDER ALERT

    Oh no! It seems as if some one has destroyed our network! Our previous Network Engineer wasn’t too experienced and forgot to set some passwords and secure the networks from intruders!

    Not only did they mess with our configurations they rearranged some of the wires! Now we don’t know what goes where! They also stole a hub and I believe they have my stapler!

    All is not lost, I found the field operations manual (FOM) and back up logs from our previous Network Engineer that kept diligent details of the Logical Topology and IP Address Schemes!!ospf

To be a Network Engineer or not to be?

“All roads lead to Rome…” Routes,  infrastructures, hidden passages, tunnels……railroads.

   As I’ve mentioned before, I love Packet Tracer. I love playing with the commands and building new and interesting networks.

Routing & Switching, VLAN, EIGRP, IPv4, DHCP

Packet Tracer from CiscoVlanDhcpEigrpIpv4

I love Packet Tracer. 

You can be as creative as you like. You can purposefully destroy your creation and rebuild it, with a new or existing foundation. It’s like a never-ending puzzle, it can go on forever! 

It’s not to difficult to master, as long as you can memorize some coding and commands. Everything else is up to you, you choose how you want to connect. There are open and closed doors, locks and chains, clicks and  cliché’s! I’m not just talking about packet tracer any more either, I’m talking about computer networking and network engineering. 

Click Here  to download the Packet Tracer Topology/File on “Routing & Switching, VLAN, EIGRP, IPv4, DHCP”.  It’s fully configured and ready to go!
