  • how to ping cisco switch with heavy byte packet

    I have problem while ping a cisco 2970 switch,
    i use the following command.
    ping 10.10.10.3 -t -l 20000
    then it gives me request time out.
    but it ping smoothly with -l 17000,
    so i want to ping with heavy byte packet more than 20000 bytes,
    Please help me to sort out this problem.

    Can you ping other devices with 20000 bytes?

    Is it possible the switch is over loaded?

      HI,we also have cisco switchs getting from [MOD DELETED],but I can pass this test.In my opinion,you can run show interfaces,and have a look if your mtu value is 1500.Actually,If the data packet exceed your switches MTU size(1500), it will automatically spilt into multiple.
      Maybe you can capture packages with wireshark from this switch.I think you will find what you wanted.
      For more information, you may feel free to contact me: [MOD EDIT]
