Four Important Commands For Your CCNA / CCNP Home Lab
Posted in Computers on August 27th, 2009 by cahyoMore CCNA and CCNP candidates than ever before are putting together their own home practice labs. It’s more affordable than it ever has been, and I receive emails daily from new CCNAs and CCNPs who say it’s the best thing they could have done to improve their studies.
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 easier for you. Let’s take a look at just a few of these.
The command “no exec” is short, yet powerful. Occasionally you’ll have what is referred to as a “rogue EXEC” process tie up a line, and you end up having to continually clear lines, which disrupts your practice. If you have an access server, I highly recommend you configure this command on your lines, as shown here:
ACCESS_SERVER(con)#line 1 8
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 something that is not an IOS command – and that includes mistyped commands, which happens to all of us sooner or later. Make sure to run that command in global configuration mode on all your practice routers.
