Hi,

The extended ping command can do this for you.

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

As the other posters have already noted, extended ping, i.e. entering ping followed by an enter, will prompt you for various options including size (also offers a range of size too).  However, the later IOSs also offer some of those options on the command line, size being one of them.  Enter ping and question mark to see if those additional options are offered.

Well you didn't even try to test how extended ping works...

I hope this thread will clarify things for you:

You can do something similar with extended ping, e.g.:

router#ping

Protocol [ip]:

Target IP address: 10.178.0.3

Repeat count [5]:

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]: 36

Sweep max size [18024]: 1500

Sweep interval [1]: 32

Type escape sequence to abort.

Sending 230, [36..1500]-byte ICMP Echos to 10.178.0.3, timeout is 2 seconds:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!

Success rate is 100 percent (230/230), round-trip min/avg/max = 1/2/17 ms
