MTR-V display version information for MTR

Mtr-r reported mode display

Mtr-c set the number of packets sent per second

Mtr-s to specify the size of the ping packet

Mtr-n No-dns does not do domain name resolution on IP address

Mtr-a to set the IP address of the sending packet this is useful for a host by multiple IP addresses

Mtr-i Use this parameter to set the request between ICMP returns the default is 1 seconds

The first column: Displays the IP address and the native domain name, this is similar with the tracert.

The second column loss%: is the packet loss rate for each corresponding IP displayed.

The third column snt:snt equals 10, sets the number of packets sent per second, and the default value of 10 can be specified by parameter-C.

Fourth column last: The most recent return delay shown.

Fifth avg: mean, this should be the average delay for sending ping packets.

Best of the Sixth column: the time with the shortest delay.

The Seventh column Wrst: The worst or longest time delay.

The eighth column StDev: standard deviation.

2, set the number of packets sent per second 30
