I'm trying to debug a fiber connection between two datacenters in
Zurich. Unfortunately the other companies involved are not very
responsive. And please bear with me, I am not a network engineer, I am
just the poor guy who got this thingie on his desk...
Here is what I am trying to achieve:
In each datacenter we got an Arista DCS-7050T-52 with each an SFP
1000BASE-LX which supports up to 10km links on single-mode and 550m on
We got a 1Gbps "dedicated Layer2 Connection incl. Managed Switch" from
Init7. As far as I know, they are using Sunrise as partner to provide
the connection. We are connecting to a SMF with 1310nm.
If I put everything together, I still see a "notconnect" on the
Unfortunately the "Platin" support seems to be more like "Bronze", we do
not get a proper response right now.
Currently I can't tell if there is something wrong within our setup or
within the setup of our provider.
I would like to get a third party with a proper testing device (and more
experience than me) to meet me in the datacenter(s) and help me to find
evidence what the heck is going on.
