1500 I've encountered a problem on a cisco ws-c3750x-48ts-s where jumbo-frames won't cross a trunk-connection between a vwmare esx-host and the switch :.
theThe access ports in the same vlan don't experience any problems.
I suspect that the problem lies with the mtu for the SVI for that vlan, since it's derived from the system mtu value and not the system-mtu jumbo command :
isIs there a way to increase the SVI MTU to 9198, since system mtu has a max-value of 1998?
