Constitution Of India Chart ENGLISH LAMINATED Wall Chart published this article page no 23 more ccna and ccnp candidates than ever before are putting together their own home practice labs. its more affordable than it ever has been and i receive emails daily from new ccnas and ccnps who say its the best thing they could have done to improve their studies. there are some commands you can configure on your lab routers that wont necessarily be on your ccna or ccnp exams but they will make life a lot easier for you. lets take a look at just a few of these. the command no exec is short yet powerful. occasionally youll 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. there are two commands i like to configure on the console line on all my practice routers and switches. the first is exec-timeout 0 0 which prevents you from being kicked out of enable mode and back into user exec after a few minutes of inactivity. (this doesnt sound like much but youll get pretty tired of typing enable after a while.) the first zero refers to minutes the second zero to seconds. setting them both to zero disables the exec-timeout function. the second command prevents the router from interrupting the command youre typing with a console message. if youve ever been in the middle of typing a router command and suddenly youre interrupted with a logging message you know that can be pretty annoying. we dont want the router to not display the message but we do want the router to wait until were done entering data. the command to perform this is logging synchronous. r1(config)#line console 0 r1(config-line)#exec-timeout 0 0 r1(config-line)#logging synchronous you wont see many of these commands on your exams but after you configure them on your home lab devices youll wonder how you did without them Ideal for Civil Services buy.
