Different MTU size's in a single ping command

[Ahmed Mukhtar]

Hello

I have a question which may sound silly...But if i want to ping any ip say i want to ping 1.1.1.1....so can i ping it with Multtiple MTU sizes???

like when i hit the command

Rx# ping 1.1.1.1

Then can i make each ping go with a different a Different MTU size if i want ??? by any command or something??

I want the output to be something like this....

Means each ping Goes with a different Byte Size or MTU size....

Reply from 192.168.1.1: bytes=32 time=2ms TTL=64

Reply from 192.168.1.1: bytes=64 time=2ms TTL=64

Reply from 192.168.1.1: bytes=100 time=2ms TTL=64

Reply from 192.168.1.1: bytes=150 time=7ms TTL=64

Its just an example i took but it clears the concept i think

can this be done??

Thank you

Hi,

altough it is a duplicate post I'll reiterate my first answer: extended ping !

here's an example

R1(config)#do ping

Protocol [ip]:

Target IP address: 10.0.0.2

Repeat count [5]: 1

Datagram size [100]:

Timeout in seconds [2]:

Extended commands [n]: y

Source address or interface:

Type of service [0]:

Set DF bit in IP header? [no]:

Validate reply data? [no]:

Data pattern [0xABCD]:

Loose, Strict, Record, Timestamp, Verbose[none]:

Sweep range of sizes [n]: y

Sweep min size [36]: 80

Sweep max size [18024]: 90

Sweep interval [1]: 5

Type escape sequence to abort.

Sending 3, [80..90]-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds:

!!!

Success rate is 100 percent (3/3), round-trip min/avg/max = 24/33/44 ms

R1(config)#
