I have a few questions on how the PowerConnect 6248 handles MTU sizes:
1. It appears if I have a host using jumbo frames at 9000 MTU then I have to use a MTU of 9216 to match?
2. I can apply a MTU size under a VLAN using the "ip mtu" command but I can't set it to 9216 since I get an error back saying "Value is out of range. The valid range is 68 to 9198." I understand why since 9216 isn't even a valid standard for jumbo frames. So is the MTU size on the port vs VLAN suppose to be different to support a MTU of 9000?
3.Do I have to apply a MTU size to a VLAN? My intent is not all VLANs on the physical port need jumbo frames.
