Set MTU 9000 in cause network failure

[Wong KY]

Hi All,

I've just upgrade my freenas from 9.3 to 9.10 2 days ago. Before upgrade， I've configure "MTU 9000" in Ethernet and stuff went fine. However, after download 9.10 and reboot. It said "No Configured Interfaces were found". So I cant access it from Lan exccept reset / reconfigure the NIC again.

After reset the NIC. check everything went fine and tried to put MUT back on. and issue reproduced.

Any one know the correct parameters for Jumbo Frame in 9.10 ?

Thanks

Post the output of ifconfig and indicate which interface you want to run jumbo frames on.

Here you are
[root@nas801 ~]#
[root@nas801 ~]# ifconfig
bge0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=c0099<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,VLAN_HWTSO,LINKSTATE>
ether masked
inet 192.168.200.31 netmask 0xffffff00 broadcast 192.168.200.255
nd6 options=9<PERFORMNUD,IFDISABLED>
media: Ethernet autoselect (1000baseT <full-duplex,master>)
status: active


As I mentioned above.. Although I can save the configure.. But problem happened when i reboot freeness

Aah, I see, I thought it wasn't letting you set the MTU at all. It's just not saving it on reboot. Please create a bug report at bugs.freenas.org and post the issue number here.
