How to force 10Gbase-SR to full-duplex

[tbaror]

Hi ,

I am trying to force my network cards of my freenas box to 10G full-duplex , cant find the right syntax
the type is below
Please advice
Thanks

x1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
options=407bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSU
M,TSO4,TSO6,LRO,VLAN_HWTSO>
ether 90:e2:ba:85:02:bb
inet 192.168.10.10 netmask 0xffffff00 broadcast 192.168.10.255
nd6 options=9<PERFORMNUD,IFDISABLED>
media: Ethernet autoselect (10Gbase-SR <full-duplex>)
status: active

There are some examples in https://www.freebsd.org/cgi/man.cgi...=FreeBSD+9.2-RELEASE&arch=default&format=html. The man page for the driver should also indicate which modes it supports.

To be honest, if auto isn't working you've probably got bigger problems. In that text it appears to be connecting at 10Gb. Why force it?

You do realize that with auto if errors occur and it down-speeds to 1Gb it will keep the connection, while 10Gb will just disconnect?

The 802.3ae standards do not specify a 10G "half duplex" operation mode.. If your 10G link is up and operating, it can only be operating in full duplex mode.

If the driver does offer any configuration directives to modify 10G duplex behavior, they are either part of some non-standard functionality or not relevant to 10G operation.

Same applies to 1GbE, last I checked.

Seems so.. :)

Yeah, 1GB and 10GB are basically a full-duplex or "bust" mode. There's a few exceptions for very specialized hardware, but if you have that hardware you *know* this is the case. There's no denying that problem when you have that hardware.
