Is there anyone on-list who can help me (off list) with AT DNS? I’m looking
for some information about caching DNS servers.
Thanks.

Fun fact about letsencrypt certs, they expire after a month or so.
Looks like the site admin never noticed/cared to update it (since 2016), even
though there's a nice little helper program to auto-update them that you can

We are deploying more and more server based routers (based on BSD). We
have now come to the point where we need to have 10GB uplinks one these
devices and I prefer to plug in a long range 10GB fiber straight into
the server without it going first into a router/switch from vendor x. It

Do you have any idea if fiberstore has one with both a monitor and 1310

Seeing as how they don't charge extra for an expansion port, but do for
other special ports I am thinking of just using the expansion port.

I believe that there is no 'standard' and as such the actual filter on the
mux/demux you are using may vary by mfg.

I agree, I would be talking about getting one with the 1310NM special port
for the QSFP+ input that emitts 1270-1330nm light, and then say 4 client
ports on different channels than that light range.

I think you will find the "monitor" port is most likely to be used for "lawful"

My understanding is that ports on the client side would have cut filters for
that color, having 1310 and 1550 are nice since you can hang gear you already
have off the mux for OOB and so on. I don’t think I have any CWDM with
expansion ports to test with.

I'd imagine they vary based on vendor, so you'd have to check with the specific
vendor in terms of absolute technical specifications.
A 1310 and 1550 port only allow those channels plus or minus some, manufacturer
dependent.
An expansion port passes everything not used by that device.

Thanks for the answers. From the sounds of it, no one knows the real

All Single Mode Fiber 40g Optics are using 4 cwdm channels ...
If you use a cwdm mux/demux with and expansion port and it is only

expansion port to connect the 40g Optics

I guess that is the real question. Besides the client ports that are
clearly identified by channel number on Muxes, what channels can the
special ports handle?

The issue is that once you get above 10g things start to get expensive since
you don't have options for straight 40g optics in different colors. At least
not what I see, 4x10g like you have or a single 1310 40g with no way that I see
to mux them. I guess the only way this might work would be to

Hi,
Yes Stephen, we're talking the usual like GTT...
And no latency wise they're about the same. In the 35ms range.
But I still can't figure out the 10 x drop, that level of latency
alone cannot be the factor.
