One of our CCNA students requested some command practice for ICND2 – here is one I put together for him. Please give me feedback in the comments if you find practice tools like this helpful.
Take the latest SWITCH Command Recall exam by clicking the link below. Good luck – and let us know how you scored in the comments area of this post.
Remember to read, AND TYPE, very carefully! I failed my first attempt due to just plain sloppiness.
In the first part of this series, we subdivided the processes of EIGRP into four discrete steps, and detailed troubleshooting the first two. This is taken from the 5-Day CCNP bootcamp:
- Discovery of neighbors
- Exchange of topology information
- Best path selection
- Neighbor and topology table maintenance
Let us now discuss path selection and maintenance troubleshooting.
We should all remember that we can view the topology table of EIGRP with the command show ip eigrp topology. Here we can see the successor routes (these are the best routes that are placed in the routing table) and we can see the second best routes, the feasible successor routes. These feasible successor routes are the key to the lightening fast convergence that EIGRP can offer us. When a speaker loses its successor, it can quickly install a feasible successor route in its place.
We need to remember the important rule of feasible successors. The advertised distance of the proposed feasible successor must be less than the feasible distance of the current successor route. This is actually a loop prevention mechanism.
So many students have written me excited for the upcoming Cisco Certified Design Associate (CCDA) 5 day online bootcamp. In this blog post I want to provide everyone with a preview of some of the hugely valuable content in this course.
Early in the week of the event, we review a network health checklist from Cisco Systems. We take this one step further during the bootcamp and show you how to actually obtain these measurements without breaking your budget:
- Ethernet segments should not feature a sustained utilization of 40% or higher
- All Ethernet segments should be switched – no shared segments (hub-based)
- No WAN links should feature a sustained utilization of 70% or higher
- Response times should be generally less than 100 ms
- LAN response times should generally be 2 ms
A common question for the CCNA Voice candidate is – “Just how can we translate our analog voice waveform into the digitized form that is required for Voice over IP transmission through the converged network?” These active reading questions tell the story – enjoy!
In its natural form, what signal type is the human voice?
To send voice as a series of zeros and ones is known as what type of encoding?
Converting analog voice into digital data begins with taking “snapshots” of voice very frequently. This is called what?

This Video Blog demonstrates and discusses uses for this powerful rack rental tool.
During this video I mentioned that it is now possible to view and download your saved configs, but I forgot to show from where. The location is shown below. Enjoy!

Enjoy the updates everyone, and as always, thank you so much for choosing INE.
Try these questions on for size! Learn all this and much more in the new QoS class – woohoo!
1. Based on the following configuration, what traffic will be policed?
class-map C_MUSIC match protocol kazaa2 match protocol napster ! class-map match-any C_WEB match protocol http match class-map C_MUSIC ! policy-map P_WEB class C_WEB police 64000 ! interface serial 0/0 service-policy output P_WEB
A. All Kazaa version 2 traffic is policed
B. All Napster traffic is policed
C. All web traffic is policed
D. All Kazaa version 2, Napster, and web traffic is policed
E. No traffic is policed
The C_MUSIC class-map does not specify the match-any or match-all option. The default is match-all. Therefore, for traffic to be classified in the C_MUSIC class-map, a packet would simultaneously have to be a Kazaa version 2 packet and a Napster packet, which isn’t possible.
The C_WEB class-map uses the match-any option, meaning that traffic will be classified in this class-map if it is HTTP traffic or if it is traffic that was classified in the C_MUSIC class-map. Since, no traffic will be classified in the C_MUSIC class-map, as described above, the only traffic that will be classified by the C_WEB class-map is HTTP traffic.
The policy-map P_WEB is configured to police (i.e. rate limit) traffic classified by the C_WEB class-map to a bandwidth of 64 kbps. (NOTE: The default conform-action is transmit, and the default exceed-action is drop.) Since only HTTP (i.e. web) traffic is matched by the C_WEB class-map, web traffic is the only traffic that is policed. Continue Reading
