Jumbo Packets

I am attempting to introduce jumbo packets between a web hosting server and a database server. I've enable jumbo packets on both servers as well as on the switch in which they connect. When I attempt to test my work by pinging one to the other by simply using the ping command 'ping {ip address} -l 8000, it fails. When I attempt to ping using friendly names, the ping is successful, but it is clearly communicating via ip6 versus ip4. When I use the switch -4 to initiate the ping with ip4 with friendly name along with 8000 mtu, it too fails. Anyone know my shortcomings regarding this issue?

Have you enabled IPv4 jumbo frames, or IPv6?

Can you ping the switch from each server using the IP and a 8000-byte packet?

My switch was the issue. The switch is a Cisco SG500 and only has one way to enable jumbo packets, so it universally on or off with no ipv4/ipv6 options. I found that after I enabled jumbo, it required a reboot. Doubting the configuration, I attempted to get back into the switch for a double check via the browser, but could not access. Accessed the switch via telnet and rebooted the switch again and presto, web access was restored and ipv4 packets then started to flow as well. thanks for the suggestion, as it had me thinking which led me to rebooting the switch.
