I also think powering down the PHY when interface is down is not good idea in most cases but administrators is able to do that by choosing 'none' media for drivers which use mii(4). For example, #ifconfig foo0 media none will power down the PHY. Of course igb(4) is not aware of mii(4) so the command above does not work at this moment. > Jack > > > On Fri, Dec 3, 2010 at 11:41 AM, Eugene Grosbein <egrosb...@rdtc.ru> wrote: > > > On 04.12.2010 01:37, Mike Tancsa wrote: > > > > >> Now I see, thanks. > > >> > > >> Is it technically possible to bring link down > > >> for distinct port of dual-port em/igb-supported NICs using software? > > >> > > >> If yes, I'd like to patch my source tree. > > >> For EtherChannel this kind of management should be possible. > > > > > > > > > If your switch port's speed and duplex are manual, change the media > > > options on the NIC to something like 10 half.
