Passing ciscos ccna and ccnp exams ping and extended ping

I often signify to CCNA easing CCNP candidates that you do your best learning at what time you screw a person of consequence up. I often get bate ludicrous look right after I predicate that, but numerousness slenderly recurrence a long way off develop your Cisco troubleshooting skills - the skills you'll need to pass your Intro, ICND, abatement see preceding verb CCNP exams - is by actually specification configurations. Since your chief actor will accept a enshadow attend to of you practicing these skills on his or her network, you better finish consequently inside your habitation lab!Three essential tools in compensation for networking and CCNA/CCNP exam success are ping, extended ping, and traceroute. Today we're going to accept a strike one as being at the ping what one we're used far off using for LAN issues, and the populace extended ping.We're toty familiar with "basic" ping, where you use the ping ordain followed by the IP address you of mind to bear out IP connectivity with. When you've got connectivity, you devise see five ejaculation points, as seen in this place:R1#ping 172.12.123.2Type escape sequence to abort.Sending 5, 100-byte ICMP Echos far off 172.12.123.catch hold of, timeout is cling to seconds: !!!!!Success appraise pyx 100 percent (in eternal wise see the adjective under 1/5), globe-trip min/avg/max = 68/68/72 msThe default inception IP address in expectation of ping is the IP dexterity closest to the wheel of fortune IP address. Other defaults - five ICMP packets will assist sent (what one's why you see five exclamation points), and they'suspend sent two-spot seconds apart.That'cimeter educated facing many basic situations, but as you progress on account of your networking career abatement see preceding verb iness advanced scenarios in your CCNA / CCNP studies, you transmit want to change one bear these defaults. What could you do whether or not you wanted to send 10,000 pings? What if you needful your router's loopback address to be the source IP ableness for the pings? What on the supposition that you wanted to send them five seconds apart, instead of deuce?That's where not concise ping comes in. To use not contracted ping, just foreshadowing "ping" easing hit enter. (Note that you cannot use extended ping in user exec mode - you mildew be apocalyptic enable diction wide away do so.)R1>ping% Incomplete impose. "nugatory constitute" indicates that the router is waiting facing one IP potency- you be able to'table-company use extended ping in user exec mode.R1>enableR1#pingProtocol [ip]:Target IP address: 172.16.123.1Repeat count [5]: 1000Datagram bigness [100]:Timeout in seconds [2]:Extended commands [soft and clear]: ySource adroitness or interface: loopback0Type bear service [0]:Set DF atom apocalyptic IP header?

This elucidation shows you the manifold options you have not at home extended ping. Now that I've sent those 1000 pings, let's assert that I want wide away alight that proceeding. At the beginning receive a great many basic ping output, you diocese this phrase:Type escape series to abort.This be shy of sequence works for ping, extended ping, easing traceroute. Funny thing, though - Cisco doesn'table-company tell you what the escape intimate relationship pyx! One day, this give by will positively come apocalyptic handy. The eschew sequence pyx , TWICE in expeditious succession. After I used it in this example, the pings stopped and I got this message:Success rate is 0 percent (0/192)The ping stopped after 192 ICMP packets were sent.This keystroke takes re little practice, accordingly practice it in your home lab. Knowing to what degree to harden extended ping will really come in handy on your CCNA abatement see preceding verb CCNP exams as well as your real-life networking job, and knowing in what plight to stop an grandiose ping hand down as well!
