ICND2 Command Recall Practice Tool 1
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.
Are you a CCNP or CCIE student looking to challenge your perfect knowledge of Catalyst switchport commands?

Remember to read, AND TYPE, very carefully! I failed my first attempt due to just plain sloppiness. 
As you may have noticed, INE does a wide variety of training in the Cisco space. 
This blog post goes out to all those folks who have recently begun their Cisco training.
This month we delivered new live classes on CCNA and CCNP. We are excited for and encourage our students at every level in their journey. In that light, we have gathered a collection of Videos Answers, targeted at the CCNA level, with a few topics leaking into security and CCNP. These videos were primarily created as quick (under 10 minutes each) Video Answers to questions that various learners have had.
Take a look at the list of topics, and if there are 1 or 2 you feel you would benefit from, feel free to enjoy them.
Here are a few of the topics (in no particular order):
- How the network statement really works in IOS
- Setting up SSH
- Initial commands for sanity sake
- NAT with overload
- Router on a stick
- VRFs Continue Reading

Question 1:
Can anyone explain what is VPN intercept?
–
Bhavik Joshi
VPN Intercept can mean a few different things, depending on the specific context.
One interpretation is from a driver perspective, where a VPN connection breaks the binding between TCP/IP and the physical interface, acting as a shim. See also:

Another meaning can be in regards to intercepting SSL traffic.

This blog post is taken from the INE Resources area Understanding Frame-Relay Traffic Shaping presentation by Brian Dennis.
Overview
Frame-Relay traffic shaping is designed to control the amount of traffic the router sends out of an interface or out of a particular DLCI. Common reasons for Frame-Relay traffic shaping are:
- It allows the router to conform to the rate subscribed with the service provider
- It allows for the throttling of a higher speed site (768K) so that it does not overrun a lower speed site (64K)
Traffic shaping is designed to delay excess traffic, whereas policing is designed to drop excess traffic.
Terminology
- Available Rate (AR) – the actual physical speed of the interface; on a DCE serial interface this is determined by the configured clock rate. On a DTE serial interface, it is determined by the received clock rate. A router will always (by default) try to send out at the AR regardless of the interface bandwidth. AR is also commonly referred to as port speed, line rate, or access rate.
In this post, we will examine PAP and CHAP forms of PPP authentication. The emphasis here will be on the fact that these technologies are one-way in nature. So many of my CCIE-level students believe that they must be configured in a bidirectional configuration. I guess this is because it is what traditional Cisco classes always demonstrate at the CCNA and CCNP levels.
OK – I have pre-configured two routers, R1 and R2, they are connected by their Serial 0/0 interfaces. Let us begin with R1 as a PPP PAP server, and the R2 device as the PPP PAP client. If you ALWAYS think of these technologies (PAP and CHAP) in terms of CLIENT and SERVER commands, you will be in excellent shape.
One of the key facts regarding Access Control Lists (ACLs) that we drill into your head during CCNA is the fact that the lists you create end with what is called the “implicit” deny all. You do not see it, but the effect is undeniable. Any packets that do not match any of the permit statements in your list get deny treatment. In the case of our filtering access lists, this means the packets are dropped. As you recall from the course, this is why we desperately require at least one permit entry in all of our filtering access control lists.
But what if we want to track what we actually drop as a result of this powerful implicit deny all effect? Well, a clever trick is to end the list with an explicit deny statement and log the result. In this post, we will examine this technique.
