Hello,
We recently added a few Meraki MS switches to our network.
After reviewing some archived emails regarding Meraki I have come to the
conclusion that Meraki and SNMP-based monitoring tools are not very
compatible. I have issues with both Netdisco and another tool, Cacti,
regarding only the Meraki devices.
That being said, I was able to perform a macsuck and arpnip after following
the instructions within an archived email. I had to modify the
~netdisco/perl5/lib/perl5/SNMP/Info.pm file and create a
~netdisco/perl5/lib/perl5/SNMP/Info/Layer3/Meraki.pm file.
I can't help but feel that I hacked the solution together from the emails
and other Layer3 device files. I am not very confident in this approach
since I don't know much about the inner workings of Netdisco or the Perl
files.
I am curious if anyone else has created their own "Meraki.pm" kind of file
and if you would be willing to share it.

For a year I supported a customer with meraki, a large retail chain with
over a thousand branches of mx, ms, mr's, and they were mostly the bane of
my existence having to be the "meraki guy" for a short while (until I quit,
guess why). For Netdisco and Meraki, I found most things fairly broken
snmp-wise, largely due to the mx being less than useful for neighbor data.
I never could get netdisco to talk snmpv3 to them as meraki uses oddly
sha/des, but librenms would work. The ms were better, actually providing
more L2 info than mx router devices via librenms, but I never spent much
time beyond never figuring out why I couldn't poll them with librenms using
sha/des.
I used to harp on the Cisco SE about it, he just told us we should use the
API, but not so much an option for Netdisco. So then the customer bought
Netbrain (a commercial tool like Netdisco), which used their API's, but
guess what, it still sucked as we'd constantly hit api rate limits to poll
all the data we wanted as we might from SNMP. Then we found the API didn't
give performance counters like SNMP, and then told to use both SNMP and
API. We'd get excuses that Netbrain was "doing it wrong" requesting too
much data, but Netbrain engineering just shrugged, unable to do more, and
said "get a better vendor product than Meraki". I agreed.
There was simply no winning with Meraki really, I simply gave up trying and
voted to replace them or quit trying. Part of my quitting that customer
was really to wash my hands of having to deal with Meraki as a whole, and I
just don't see it as a real enterprise solution if you want to use tools to
monitor things beyond what their simplistic idiot UI's provide. Even the
whole template model wasn't very good at scale, and their monitoring
capabilities, snmp or other, were terrible. I just never got why people
would use them beyond a mom and pop operation, but cisco pushes them full
on against catalyst now. Caveat emptor.
