Considering IT Certification – GO FOR IT!

CCIE Coaching, , ,

Are you considering that leap to get certified because you realize the advantages far outweigh the disadvantages? Are you already heavily certified (or certifiable) and you want to add that next big one to your list? Hopefully this article gets you moving in the right direction FAST!

DECIDE!

Sit down, take a breath, and decide to really do it. Hell – you might even schedule it. As Tony Robbins likes to say – “If you talk about it, it’s a dream, if you envision it, it’s possible, but if you schedule it, it’s real.”

STOP WASTING TIME!

You have as much (or as little) time as many others that have achieved the same task. Take a look, a hard look, at where you are spending your precious minutes throughout the day. You just might find that many of those minutes are spent on activities that do not really serve you.

KNOW THE PRICE! 

Be sure you think about the costs of your certification. Sure we might be talking about actual costs here like exam prep materials, exam fees, etc, but we are also speaking of the costs in time and the potential hindrance on your personal relationships. You might even have the cost of some lost income based on setting aside more time to study instead of dedicating more time resources to generating income.

SHARPEN PROBLEM SOLVING!

There are going to be setbacks in your IT Certification pursuit. Just how well you handle those setbacks and make them strengths just might separate you from the rest of the pack!

GO! 

So decide and start now if it is for you! Don’t waste any more time in getting that momentum started.

Did you ever stop and think about just how many options you have for controlling traffic in the data plane on a multilayer Cisco Catalyst switch?

Here is a recap of your options –

  • Port ACL (PACL) – this option is for your Layer 2 switchports. You can apply:
    • IP standard or extended ACLs for controlling IP traffic
    • MAC ACLs for controlling non-IP traffic
  • Router ACL (RACL) – this options is for your Layer 3 ports on the router. You can apply:
    • IP standard or extended ACLs for controlling IP traffic
  • VLAN ACL (VACL) – these are also referred to as VLAN Access Maps. You can apply:
    • IP VLAN maps are for controlling IP traffic
    • MAC VLAN maps are used for controlling non-IP traffic

For most of us – we are well-versed in IP extended and standard access control lists. It is the MAC ACLs of the PACL approach and the VACLs that we need the practice with. I will be sure to publish my CBT Nuggets on this subject on YouTube for all to enjoy.
