Passing Cisco CCNA And CCNP Exams: Ping And Prolonged Ping
I normally explain to CCNA and CCNP candidates that you just do your best Finding out any time you screw anything up. I normally obtain a amusing search correct just after I claim that, but the sole strategy to acquire your Cisco troubleshooting abilities – the skills you’ll must move your Intro, ICND, and CCNP tests – is by basically fixing configurations. Since your employer will have a dim see of you practicing these skills on her or his network, you much better do this on your house 토토사이트 lab!
3 essential applications for networking and CCNA/CCNP Test accomplishment are ping, prolonged ping, and traceroute. Now we’re intending to Have a look at the ping that we’re used to applying for LAN challenges, and the extended ping.
We’re all familiar with “basic” ping, in which you use the ping command accompanied by the IP handle you wish to confirm IP connectivity with. If you’ve obtained connectivity, you will note five exclamation factors, as witnessed in this article:
R1#ping 172.twelve.123.two
Kind escape sequence to abort.
Sending five, one hundred-byte ICMP Echos to 172.twelve.123.2, timeout is two seconds:
!!!!!
Results fee is 100% (five/5), spherical-vacation min/avg/max = 68/68/seventy two ms
The default resource IP handle for ping is definitely the IP tackle closest towards the vacation spot IP handle. Other defaults – 5 ICMP packets is going to be sent (that’s why you see 5 exclamation factors), and they’re sent two seconds apart.
That’s wonderful For several primary scenarios, but while you development by your networking occupation and most Superior scenarios within your CCNA / CCNP studies, you should transform Many of these defaults. What could you are doing in case you wished to send out ten,000 pings? What if you necessary your router’s loopback handle being the resource IP address with the pings? Let's say you planned to send them five seconds apart, as opposed to two?
That’s where http://www.bbc.co.uk/search?q=먹튀검증 by extended ping comes in. To implement extended ping, just sort “ping” and hit enter. (Be aware that You can't use prolonged ping in user exec method – you should be in help method to take action.)
R1>ping
% Incomplete command.
“incomplete command” indicates that the router is expecting an IP tackle; you are able to’t use extended ping in user exec manner.

Sending 1000, a hundred-byte ICMP Echos to 172.16.123.1, timeout is two seconds:
Packet sent by using a source tackle of 1.1.1.1
…………………………………
In this instance, I sent 1000 ICMP packets to an handle that doesn’t exist, so I am getting intervals instead of exclamation details. This illustration exhibits you the many selections you've got with prolonged ping.
Now that I’ve sent These 1000 pings, Allow’s express that I need to stop that system. Firstly of The fundamental ping output, the thing is this phrase:
