HI C:\>ping 192.168.10.4 C:\>ping 192.168.10.5 Here what i would like to find is the efficiency of running with Gigabit NIC. How to differentiate while pinging that its gigabit or fast ethernet....? If not with ping any other command would give the kind of result iam looking for? Need specific answer pls? Thanks Praveen MOhan

As a professional network consultant, doing a Ping would not be my method of choice in deteriming if I'm gettin gigabit speed or fast ethernet. Ping was designed for WAN troubleshooting not LAN troubleshooting. You do have options when using a Ping test like the "-l" ("l" as in the letter) which you can increase the buffer size bytes being transmitted. You can go as high as 65500 bytes...here is such an example of a command "ping 192.168.2.1 -l 65500". But that still wouldn't be able to help you identify if it's 100Mbs or 1000Mbs. Generally physical inspection is your first line of identification. You have to have a Gigabit NIC on both sides of the transmission and the cable has to be rated at Cat 5e (Not Cat 5) or Cat 6 or above. If any one of the three components does not match you can not support Gigabit. If you have all of those physical components and for some strange reason you don't think your Gigabit is transmitting at Gigabit you want to run a data transfer, and clock the rate at which the data transfer occured. Some people make large data files or download such a file with a timing feature off the net but I've only seen the ones for 45Mbs or less which is what you use to test out your Service Provider at the DS3 level or below. I don't know of any trying to test at 100Mbs or above. Is there any reason why you cant verify your Gigabit physically rather than using a program? And if not, just transfer some Big "A" files and clock how long to take to transfer. D

Hi Thanks for your insights. Well,physical inspection is difficult because iam at the remote place only be able to troubleshoot thru telnet,putty etc. As far as another solution of copying the file is concerned it looks fairly fine.. However,the problem is i have many nodes to check so it would tedious to sit and copy to prove the point. Any other easier solution just by giving command of at what speed can the transmission happen would be much appreciated. Hope making the case clear. Thanks a ton
