This week was a bit of a clusterfuck.

I still got paid to work, so that's a good thing, but a clusterfuck nonetheless.

Customer wanted fiber run from one building to an outbuilding. They had conduit all laid out and buried, pullstrings, that was all set. The path between the main datacenter in the main building and the MDU in the outbuilding was easy enough.

Problem is, #Arista (who is going to be providing their switches when they do their network upgrade here soon) told them they needed to use single-mode fiber "for future-proofing"... Problem is, the run was less than 600 feet.

Wednesday we laid out the single-mode fiber and ran it between the buildings, only to find out the customer didn't have any single mode SFPs to plug into their switches... So they ordered some and asked if I could come back Monday...

Thursday I get a call from my boss letting me know that I'm going back Friday (today) to run multi-mode along side the single-mode I've put in already... .and terminate it at both ends.

Got all 600 feet of it run, terminated the fiber ends, and cut over to the new link.

Now they can finish remodeling the outbuilding, put a roof on it, etc, etc, etc, and take the old aerial drop down.

In a few weeks I'm going back to run copper to all the workstations in the building. At that time I get to re-terminate the fiber in that MDF.. because I had to make this one TEMPORARY.. because the cabinet/rack they had in that room was only 12" deep. I'll be hanging a new, 24" deep cabinet, installing a proper LIU, and performing all the cable management necessary to make it beautiful and functional.

The single-mode is still there. Maybe they'll use it in the future for extension to a further building, but it's going to go un-used now... It was installed for naught... but at least I got paid to do what the customer wanted.

I now have a working #IEEE #1588 hardware-corrected #time sync setup using an #Intel #I226V card. No #Arista switch required. FreeBSD #ptpd slave sees #linuxptp master. Yet to test with the #NVidia #Mellanox #ConnectX-4 LX clients in #FreeBSD though. #BeagleBone Black support appears broken. Awaiting a #SiRFStar IV USB #GPS with alleged #PPS capability, and yet to recover my #GPSDO unit from my aunt's attic in Fife.

Crazy. Considering a (near-to-mid) future upgrade of our house network to 10 gigabit. Most switches are in the multi-thousand-Euro range, and have only SFP+ ports (for which you need transceivers, which are not 1000Base-T downwards compatible), but there is currently an abundance of used #Arista 48-port 10GBase-T switches for under 200€. I wonder what the catch is. Licensing? Or power consumption?

I've now spent many hours trying to solve a problem with my first #Arista, a DCS-7010T-48 TOR switch. My knowledge is mostly Cisco but I wanted to dabble a bit with Arista to compare. As far as I can tell, the switch boots OK but none of the 48 ethernet access ports are present. No controller/supervisor shows in the inventory. I don't think they're just shut/disabled but I can't find that right EOS (4.29.0.2F) commands to diagnose this further. It's frustrating. ->

@karppinen and #arista 7050 / 7160 / 7280sr/tr . I'll was looking for a bag like that recently, more convenient than a flight case for transport in bus/train. Thanks for the tip !
