Cisco Ccna (640-553) security Exam Training - Using the "Clear Crypto Isakmp" Command

In today's article, I'm going to familiarize you about the Cisco Ios privileged Exec mode command named "clear crypto isakmp." Ccna's (like you) use this command to clear active Internet Key change (Ike) connections.

Below is the command's syntax:    

Cisco Router

clear crypto isakmp [connection-id] [active | standby]

connection-id-This (optional) argument is the Id of the association that is to be cleared. If this argument is not used with the command, all existing connections will be cleared by default.    

active-This (optional) keyword is used to only clear (remove) Ike safety associations (Sas) that are in the active state.     

standby - And, this (optional) keyword is used to only clear Ike Sas that are in the standby (secondary) state. Remember, if the router is in standby mode, the router will immediately resynchronize the standby Sas; thus, it may appear as if the standby Sas were not cleared.     

In the example below, all existing Ike connections are being cleared:     

Router#clear crypto isakmp

Note: You can use the privileged Exec mode command named "show crypto isakmp sa" to display (view) current Ike Sas.

And, if you conclude to use the command, make sure your router(s) is running Cisco Ios 12.3(11)T or higher.  

I hope this narrative was very informative and helped you fast understand the usage of clear crypto isakmp command. If you need to learn more; I recommend you visit my website, were you'll find the most recent data regarding the Cisco Ccna (640-553) safety exam techniques to help you make your day a minuscule brighter.

Cisco Ccna Exam Tutorial: Loopback Interfaces

As a Ccna candidate, you most likely have some background in Pc hardware and workstation support. If so, you're already familiar with loopback interfaces, particularly 127.0.0.1, the loopback address assigned to a Pc.

When you're studying all about the separate physical interfaces for your Ccna exam - serial, ethernet, and Bri, among others - there's one logical interface you need to know about, and that is - you guessed it! - the loopback interface.

Cisco Router

What isn't as immediately apparent is why we use loopback interfaces on routers and switches to begin with. Many of the Cisco router features that can use loopbacks are intermediate and advanced features that you'll learn about in your Ccnp and Ccie studies, but these features all come back to one basic concept: If the loopback interface on a router is down, that means the router is unavailable as a whole.

Cisco Ccna Exam Tutorial: Loopback Interfaces

In contrast, a physical interface being down does not mean the router itself is out of commission. A router's ethernet port can go down, but the other physical interfaces on that router are still operational. Since a loopback interface is logical, there's nothing physical that can go wrong with it.

As I mentioned, you'll learn separate Cisco router and switch features that use loopback interfaces as you climb the Cisco certification ladder. There's one misconception about Cisco loopback interfaces that you want to get clear on now, though. You're probably familiar with loopback interfaces on a Pc, and may even know that the address range 127.0.0.0 is reserved for loopback addressing.

Note that this reserved address range does not apply to loopbacks on Cisco devices, however. If you exertion to assign an address from this range to a Cisco loopback interface, you get this result:

R1#conf t

Enter configuration commands, one per line. End with Cntl/Z.

R1(config)#interface loopback0

R1(config-if)#ip address 127.0.0.2 255.255.255.0

Not a valid host address - 127.0.0.2

R1(config-if)#ip address 127.1.1.1 255.255.255.0

Not a valid host address - 127.1.1.1

The range 127.0.0.0 is reserved for host loopbacks (such as Pcs), not routers or switches. The most commonly used address from this range is 127.0.0.1 - if you can't ping that on a workstation, that means you can't ping yourself, which means there's a qoute with the Tcp/Ip install itself.
Keep these details in mind on the exam and in the workplace, and you're on your way to Ccna exam success!
