A. An easy way to check if you're sending 9kB packets instead of the 1.5kB standard is to use the ping command. Use a data size of 8kB bytes along with the no-fragment switch.

                              ping <server> -f -l 8000                              

As can be seen in my example below, I can successfully use jumbo frames to talk to savdalvs02, but not to savdalwks01. If I reduce the packet size to 800B, it works just fine for non-jumbo frame hosts.

If I use the command

                              ping savdalvs02 -f -l 8000                              
I'll see
                              Pinging savdalvs02.savilltech.net \[192.168.1.31\] with 8000 bytes of data:                              Reply from 192.168.1.31: bytes=8000 time<1ms TTL=128                              Reply from 192.168.1.31: bytes=8000 time<1ms TTL=128                              Reply from 192.168.1.31: bytes=8000 time<1ms TTL=128                              Reply from 192.168.1.31: bytes=8000 time<1ms TTL=128                              Ping statistics for 192.168.1.31:                              Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),                              Approximate round trip times in milli-seconds:                              Minimum = 0ms, Maximum = 0ms, Average = 0ms                              

But if I enter

                              ping savdaldc10 -f -l 8000                              

I'll see
