ABOUT ME

I usually tell CCNA and CCNP candidates that you do your greatest understanding when you screw something up. I typically get a amusing look correct soon after I say that, but the only way to create your Cisco troubleshooting capabilities - the competencies you may require to move your Intro, ICND, and CCNP exams - is by truly repairing configurations. Due to the fact your employer will consider a dim watch of you practising these competencies on his or her network, you superior do so on your household lab! 3 important equipment for networking and CCNA/CCNP exam achievement are ping, prolonged ping, and traceroute. Nowadays we're heading to take a search at the ping that we're utilised to using for LAN troubles, and the prolonged ping. We are all acquainted with "standard" ping, wherever you use the ping command adopted by the IP address you want to affirm IP connectivity with. When you have got connectivity, you will see 5 exclamation details, as seen here R1ping 172.12.123.2 Form escape sequence to abort. Sending 5, a hundred-byte ICMP Echos to 172.12.123.2, timeout is 2 seconds !!!!! Accomplishment rate is 100 percent (5/5), round-trip min/avg/max 68/68/seventy two ms The default resource IP handle for ping is the IP deal with closest to the vacation spot IP deal with. Other defaults - 5 ICMP packets will be sent (that is why you see five exclamation details), and they are sent two seconds apart. That is good for a lot of standard conditions, but as you progress via your networking job and most state-of-the-art eventualities in your CCNA / CCNP reports, you will want to adjust some of these defaults. What could you do if you desired to send 10,000 pings? What if you essential your router's loopback deal with to be the resource IP tackle for the pings? What if you wished to deliver them 5 seconds apart, as a substitute of two? That's exactly where extended ping arrives in. To use extended ping, just kind "ping" and strike enter. (Notice that you cannot use prolonged ping in person exec mode - you must be in permit mode to do so.) R1ping % Incomplete command. "incomplete command" suggests that the router is waiting around for an IP deal with you cannot use prolonged ping in user exec mode. R1enable R1ping Protocol ip Focus on IP tackle 172.16.123.one Repeat depend 5 1000 Datagram size one hundred Timeout in seconds two Prolonged commands n y Resource handle or interface loopback0 Form of service Set DF bit in IP header? no Validate reply info? no Information routine 0xABCD Unfastened, Stringent, Document, Timestamp, Verbosenone Sweep selection of measurements n Form escape sequence to abort. Sending a thousand, 100-byte ICMP Echos to 172.sixteen.123.1, timeout is two seconds Packet sent with a supply tackle of one.1.one.one ....................................... In this example, I sent one thousand ICMP packets to an handle that isn't going to exist, so I am getting durations as a substitute of exclamation factors. This illustration demonstrates you the many selections you have with prolonged ping. Now that I have sent those 1000 pings, let's say that I want to stop that course of action. At the beginning of the basic ping output, you see this phrase Variety escape sequence to abort. This escape sequence performs for ping, extended ping, and traceroute. Humorous matter, nevertheless - Cisco does not tell you what the escape sequence is! A person day, this will truly arrive in useful. The escape sequence is , 2 times in speedy succession. Soon after I employed it in this case in point, the pings stopped and I received this communication Results rate is p.c (/192) The ping stopped soon after 192 ICMP packets have been sent. This keystroke requires a little practice, so apply it in your residence lab. Understanding how to use extended ping will really arrive in handy on your CCNA and CCNP exams as well as your authentic-everyday living networking career, and realizing how to stop an extended ping will as effectively!
