Passing Cisco CCNA And CCNP Exams: Ping And Extended Ping

I generally notify CCNA and CCNP candidates you do your very best Understanding any time you screw something up. I typically have a humorous look appropriate right after I express that, but the only real method to establish your Cisco troubleshooting skills – the talents you’ll have to go your Intro, ICND, and CCNP examinations – is by actually correcting configurations. Given that your employer will have a dim watch of you practising these competencies on his or her community, you greater accomplish that on your property lab!

3 vital applications for networking and CCNA/CCNP exam success are ping, extended ping, and traceroute. Nowadays we’re going to Look into the ping that we’re used to applying for LAN concerns, along with the extended ping.

We’re all accustomed to “fundamental” ping, in which you use the ping command followed by the IP handle you wish to confirm IP connectivity with. If you’ve bought connectivity, you will notice 5 exclamation details, as observed below:

R1#ping 172.12.123.two

Sort escape sequence to abort.

Sending five, 100-byte ICMP Echos to 172.12.123.2, timeout is 2 seconds:

!!!!!

Achievements rate is 100% (five/five), round-trip min/avg/max = sixty eight/68/72 ms

The default supply IP handle for ping could be the IP deal with closest on the spot IP handle. Other defaults – 5 ICMP packets will probably be despatched (that’s why you see 5 exclamation factors), and so they’re sent two seconds apart.

That’s fine For several standard conditions, but while you progress by means of your networking vocation and many Sophisticated situations https://socialhattori.com/ within your CCNA / CCNP studies, you will want to adjust Some defaults. What could you need to do should you wished to ship 10,000 pings? What if you needed your router’s loopback handle being the source IP handle for your pings? What if you desired to send out them five seconds apart, instead of two?

That’s where by prolonged ping comes in. To utilize prolonged ping, just kind “ping” and strike enter. (Take note that you cannot use extended ping in person exec method – you will need to be in enable method to do so.)

R1>ping

% Incomplete command.

“incomplete command” indicates which the router is watching for an IP handle; you'll be able to’t use prolonged ping in consumer exec method.

Sending a thousand, one hundred-byte ICMP Echos to 172.sixteen.123.one, timeout is 2 seconds:

…………………………………

In this instance, I despatched one thousand ICMP packets to an handle that doesn’t exist, so I am obtaining durations rather than exclamation points. This illustration displays you the various choices you have got with prolonged ping.

Since I’ve despatched those one thousand pings, let’s express that I would like to halt that system. In the beginning of the basic ping output, the thing is this phrase:
