Welcome!

I’m Dave Hucaby and this is my blog. In here, you’ll find a variety of things related to networking with Cisco devices. I write books and videos for Cisco Press, so you’ll find things like:

• Extra study materials for Cisco certifications
• Discussions about Cisco exams
• Interesting scenarios and problems

As the site grows, skip straight over to a category to find some useful things. I’m glad you’re here!

 

Scenario 4

One LAN switching best practice is to locate the STP root in a strategic place for each VLAN. In Scenario 4, we’ll need to configure the STP root location…

 

Scenario 3

When switches are connected together, it’s important to keep traffic flowing in both directions over the links. In Scenario 3, we’ll need to leverage a switch feature to make sure that happens…

 

Scenario 2 – Securing a Trunk

I’m going to try and pick up the pace with new scenarios. Hopefully, this one won’t be too difficult and will work like I think it should.

Today’s scenario involves securing a trunk between two switches…

 

New scenario – VLAN Trunking 1

Here’s a new scenario to think about. I haven’t built it in a lab yet, but I think it might be interesting and it just might work.

 

Door prizes – round one!

There’s been too much grief on this blog, thanks to a certain exam. It’s time to spread a little sunshine with some door prizes!!

 

CCNP Switch – SVI Autostate

Here’s the next installment of supplementary material to the CCNP SWITCH Certification Guide. This time, I cover the Layer 3 SVI autostate feature.  This content will be added to the book toward the bottom of page 221.

CCNP Switch – Planning Topics

It’s time to shed a little light on the “planning” topics of the CCNP SWITCH exam. Or is it? This is probably the most elusive part of the exam, in my opinion.  The new SWITCH course doesn’t have much content directly related to planning, other than some common sense advice. In the past, the CCNP exams were limited to the scope of the corresponding course. With the new exams, this isn’t necessarily the case.

 

CCNP Switch – IP SLA

Here’s the next installment of supplementary material to the CCNP SWITCH Certification Guide. This time, we cover IP SLA — a feature found on Cisco routers, switches, and firewalls. Cisco does include it on the 642-813 SWITCH exam. This content will be added to the book at the end of Chapter 13: High Availability, right after the SNMP section.

Wrinkles to iron out…

I’ve noticed that WordPress is truncating any long command syntax lines when I post. I’m working to figure out a solution and will fix the posts shortly.

Welcome to the learning curve.

CCNP Switch – SNMP

Here’s the next installment of supplementary material to the CCNP SWITCH Certification Guide. This time, we cover SNMP. While SNMP is not a foundational LAN switching topic, Cisco does include it on the 642-813 SWITCH exam. This content will be added to the book at the end of Chapter 13: High Availability, right after the Syslog section.
