Far more CCNA and CCNP candidates than ever before are putting collectively their own residence practice labs. It's much more reasonably priced than it ever has been, and I obtain emails day-to-day from new CCNAs and CCNPs who say it really is the ideal thing they could have completed to increase their research. There are some commands you can configure on your lab routers that won't necessarily be on your CCNA or CCNP exams, but they will make life a lot simpler for you. For other interpretations, consider peeping at: jump button. Let's take a appear at just a few of these. The command "no exec" is brief, however potent. Occasionally you'll have what is referred to as a "rogue EXEC" method tie up a line, and you finish up obtaining to continually clear lines, which disrupts your practice.

If you have an access server, I hugely advise you configure this command on your lines, as shown right here: ACCESS_SERVER(con)#line 1 eight ACCESS_SERVER(con)#no exec From your CCNA studies, you know that the command "no ip domain-lookup" prevents a Cisco router from sending a broadcast to find a DNS server anytime you enter one thing that is not an IOS command - and that includes mistyped commands, which happens to all of us sooner or later. Make positive to run that command in global configuration mode on all your practice routers. There are two commands I like to configure on the console line on all my practice routers and switches. The 1st is "exec-timeout ", which prevents you from getting kicked out of enable mode and back into user exec soon after a handful of minutes of inactivity. (This does not sound like significantly, but you'll get quite tired of typing "enable" right after a whilst.) The initial zero refers to minutes, the second zero to seconds. Setting them each to zero disables the exec-timeout function. The second command prevents the router from interrupting the command you're typing with a console message. If you have ever been in the middle of typing a router command and all of a sudden you are interrupted with a logging message, you know that can be pretty annoying. This splendid www.vimeo.com/greglombardo website has a myriad of disturbing lessons for when to provide for it. We never want the router to not display the message, but we do want the router to wait until we're completed getting into information. The command to carry out this is "logging synchronous". R1(config)#line console R1(config-line)#exec-timeout R1(config-line)#logging synchronous You will not see a lot of of these commands on your exams, but after you configure them on your house lab devices, you will wonder how you did without having them!.
