OpenBSD 6.0 - Silicom PE2G4SFPI35L Intel i340AM4 based
Dear Community, Hope all is well. I'm on my last stretch to put in production our OpenBSD/OpenBGPd implementation. I have chosen a SuperMicro box as my platform, some of our transit providers at the data center come in through 1000-Base-LX fiber cross connects hence the search for an SFP and LX capable network card. My question is, does the em driver work with Intel-based network cards of other vendors such as the Silicom PE2G4SFPI35L or the PE2G4SFPI80L, both respectively are based on Intel i340AM4 and 82580EB controllers. Or is there another card with 4-Ports 1000-Base-LX capable hardware I missed? Sincerely, Uday MOORJANI PS Loving the OS.

I haven't tried those Silicom cards but I have a couple of 6-port HotLava 1000base-T em(4) cards which are working nicely. I don't see I340AM4 on the list in the em(4) manual. I can't say whether this is just an omission from the manual, or whether it's unsupported. 82580EB is listed there. > Or is there another card with 4-Ports 1000-Base-LX capable hardware I > missed? > > Sincerely, > > Uday MOORJANI > > PS > Loving the OS. > > When I had a circuit delivered on single-mode fibre I couldn't find a suitable 1Gb SFP card for any sensible money so I used a 10Gb card instead (in my case some 82599-based Intel SFP+ which uses the ix(4) driver), which also work with 1Gb SFPs. $ ifconfig ix1 | grep -e ^ix -e media ix1: flags=8843 mtu 1500 media: Ethernet autoselect (1000baseLX full-duplex,rxpause,txpause) $ dmesg | grep ^ix1 | tail -1 ix1 at pci1 dev 0 function 1 "Intel 82599" rev 0x01: msi, address 00:1b:21:c0:25:bd

Stuart, Thank you for your quick response. We are in requirement of a 4-Port 1000Base-LX capable network card, whether it's 10GbE or 1GbE it doesn't matter. I took a look a the vendor, and I have to say it feels awesome learn something new every day. I did not know this vendor and the mere fact that they openly support OpenBSD is reassuring. I'll have my distributor take a look at it. Thanks a lot. /Uday On Fri, Mar 10, 2017 at 1:47 AM, Stuart Henderson wrote: > On 2017-03-09, Uday MOORJANI wrote: >> Dear Community, >> >> Hope all is well.
