Has anyone successfully got jumbo frames, mtu 9000 to actually work in solaris 11.1?
--------------
vmxnet3 attempt:
root@media5:~# dladm show-linkprop -p mtu
LINK PROPERTY PERM VALUE DEFAULT POSSIBLE
net1 mtu rw 1500 1500 1500
root@media5:~# nano /kernel/drv/vmxnet3s.conf
mtu=9000,9000,9000,9000,9000,9000,9000,9000,9000,9000;
root@media5:~# dladm show-linkprop -p mtu
LINK PROPERTY PERM VALUE DEFAULT POSSIBLE
net1 mtu rw 9000 1500 9000
root@media5:~# dladm set-linkprop -p mtu=9000 net1
dladm: warning: cannot set link property 'mtu' on 'net1': operation not supported
For some reason the below setting went through (for this nic only) but had no effect
root@media5:~# ifconfig net1 mtu 9000

e1000g0 attempt:
The driver seems to have jumbo frames enabled by default but i cant enable it on the interface
admin@media5:~$ sudo dladm show-linkprop -p mtu
LINK PROPERTY PERM VALUE DEFAULT POSSIBLE
net0 mtu rw 1500 1500 1500-16362
root@media5:~# ifconfig net0 unplumb
root@media5:~# dladm set-linkprop -p mtu=9000 net0
dladm: warning: cannot set link property 'mtu' on 'net0': link busy
root@media5:~# ifconfig net0 mtu 9000
ifconfig: setifprop: Invalid argument provided
It seems that the link is busy no matter what i do, i have tried disconnecting the nic and it is still busy.
-----------------
The below is a ping initiated from each nic (one active a time) to a solaris 11 express VM that has jumbo support enabled and working (verified using pings to and from a VMKernel and windows workstations)
root@media5:~# ping -s 10.0.0.36 9000 4
PING 10.0.0.36: 9000 data bytes
----10.0.0.36 PING Statistics----
4 packets transmitted, 0 packets received, 100% packet loss
Some of the guides out there use ndd -set to kick on jumbo frame support however this command no longer works in solaris 11.1
Im using ESXi 5.1.0 914609 with the latest vmware tools installed.
Does anyone have an suggestions or tips?
