I've written this to crawl network with CDP+LLDP+SNMP and produce JSON
or dotty output of topology. https://github.com/ytti/netcrawl CDP MIB
is obviously enterprise but LLDP is standard.

LLDP standard itself is in my non-humble opinion broken. There are no
guarantees that standard compliant LLDP will produce useful data.
Standard should allow multiple TLV's to describe port and device.
Standard should mandate that if device implements IP and SNMP, one of
the port TLVs SHOULD be 'ifIndex' and one of the device TLVs  SHOULD
be MGMT IP address.

I can't speak to Brocade (just haven't been to a customer recently who
has their kit and wants topology), but I've found support from Juniper,
Cisco, and Arista to be very good. As long as the device software load
is reasonably modern and LLDP is lit up everywhere, topology usually
just works.

We added LLDP support a couple years ago to OpenNMS' L2/L3
link-discovery service daemon (on top of CDP, IS-IS, and OSPF).
Everything is done via SNMP, for now anyway. If you read Java, you can
profit from our experience by sifting through the various LLDP-related
classes in our code here:

https://github.com/OpenNMS/opennms/

Tangentially, we've also been working on integration with OpenDaylight,
which pretty much demands going ReSTful to gather underlay and overlay
topology data.

RE: LLDP via SNMP

[Michael Hare]

My experience with Juniper has been mixed, experience with 12.X and 13.X made 
me wonder if I had a poor understanding of how to do a proper decode or if 
Juniper's implementation itself had issues as I would often get incomplete 
results.

We've now grab over XML and have been pleased with that choice to the point I 
no longer see it as a "resort" but the most efficient way for us to move 
forward.  I used to open JTAC cases on each SNMP problem I'd come across [ CoS, 
mac-accounting ] and it generally wasn't a good use of our time.

We use Observium for most of our SNMP monitoring, and it correctly pulls
LLDP and CDP data from all of our Cisco and Arista gear.

LLDP via SNMP

[Avi Freedman]

Have had the question come up a few times, so I wanted to poll the community to 
see...

For those who are monitoring LLDP, how have you found the SNMP MIB support 
support for it on Juniper, Cisco, Brocade, Arista, and others?

Wondering if you've needed to resort to CLI scraping or APIs to get the data?

Thanks,

Frontier routing issue?

Is anyone else in the north east seeing routing issues on frontier right now?  
Unable to get to many websites. Trace route seems to complete fine but you 
can't bring up any content.
