Re: link monitoring Saku Ytti (May 01)
This feature will be introduced by ER-079886 in some future date. You
may be confused about OTN FEC, which is available via MIB, but
unrelated to the topic.

I did plan to open a feature request for other vendors too, but I've
been lazy. It is broadly missing, We are doing very little as a
community to address problems before they become symptomatic and
undercapitalising the information we already have from DDM and RS-FEC.

Re: link monitoring Alain Hebert (Apr 30)
    Yes the JNP DOM MIB is what you are looking for.

    It also the traps for warnings and alarms thresholds you can use
which is driven by the optic own parameters.
    ( Human Interface: show interfaces diagnostics optics <interface> ] )

    TLDR:

        Realtime: Traps;
        Monitoring: DOM MIB;

    PS: I suggest you join [ juniper-nsp () puck nether net ] mailing list.

RE: link monitoring Travis Garrison (Apr 29)
We use LibreNMS and smokeping to monitor latency and dropped packets on all our links and setup alerts if they go over
a certain threshold. We are working on a script to automatically reroute traffic based on the alerts to route around
the bad link to give us time to fix it.

Thanks

Re: link monitoring Eric Kuhnke (Apr 29)
If I may add one thing I forgot, this post reminded me. In the question I
think it was probably a 100G CWDM4 short distance link. When monitoring a
100G coherent (QPSK, 16QAM, whatever) longer distance link, be absolutely
sure to poll all of the SNMP OIDs for it the same as if it was a point to
point microwave link.

Depending on exactly what line card and optic it is, it may behave somewhat
similarly to a faded or misaligned radio link under...

Re: link monitoring Lady Benjamin Cannon of Glencoe, ASCE (Apr 29)
We monitor light levels and FEC values on all links and have thresholds for early-warning and PRe-failure analysis.

Short answer is yes we see links lose packets before completely failing and for dozens of reasons that’s still a good
thing, but you need to monitor every part of a resilient network.

Re: link monitoring Eric Kuhnke (Apr 29)
The Junipers on both sides should have discrete SNMP OIDs that respond with
a FEC stress value, or FEC error value. See blue highlighted part here
about FEC. Depending on what version of JunOS you're running the MIB for it
may or may not exist.

In other equipment sometimes it's found in a sub-tree of SNMP adjacent to
optical DOM values....

link monitoring Baldur Norddahl (Apr 29)
Hello

We had a 100G link that started to misbehave and caused the customers to
notice bad packet loss. The optical values are just fine but we had packet
loss and latency. Interface shows FEC errors on one end and carrier
transitions on the other end. But otherwise the link would stay up and our
monitor system completely failed to warn about the failure. Had to find the
bad link by traceroute (mtr) and observe where packet loss started.

Re: Myanmar internet - something to think about if you're having a bad day Christopher Morrow (Apr 29)
I'm glad someone noted this...
I'd also say that it seems to me that the restrictions are a LOT like
'seatbelt laws' in the US, where most states enforce as a secondary action:
"Oh you were speeding AND you aren't wearing a seat belt, bonus fine"
(note: I'm a seatbelt user, just using this as an example)

and that the censorship COULD be used as a further action for repressing
folk:

Re: Myanmar internet - something to think about if you're having a bad day Bradley Huffaker (Apr 29)
Censorship does not need to be complete to be highly effective. Almost all regulation, drugs/speeding/etc, is
designed to increase the cost to the point were “most” individuals are discouraged. While VPNs can be used to bypass
China’s Great Firewall the added friction is enough to keep most happily engaged with easer distractions....

Hi,

Even my third-grader was able to figure out that she needed a VPN when I blocked Roblox's IP space (128.116.0.0/17) on
my home router.

Other than, as reports said, soldiers snipping cables in datacenters, regimes will have a difficult time completely
blocking whatever they don't like. Even China can't do it.

Thanks,
