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. -Michael -----Original Message----- From: NANOG [mailto:nanog-bounces () nanog org] On Behalf Of Spencer Ryan Sent: Thursday, May 26, 2016 9:51 AM To: avi () kentik com Cc: North American Network Operators' Group Subject: Re: LLDP via SNMP 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. *Spencer Ryan* | Senior Systems Administrator | sryan () arbor net *Arbor Networks* +1.734.794.5033 (d) | +1.734.846.2053 (m) www.arbornetworks.com On Thu, May 26, 2016 at 10:47 AM, Avi Freedman wrote:

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. -jeff -------------- next part -------------- A non-text attachment was scrubbed...

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. -- ++ytti ------------------------------ Message: 8 Date: Tue, 24 May 2016 14:14:04 -0600 From: David To: nanog () nanog org Subject: Re: Network traffic simulator Message-ID: <5744B60C.9090809 () shaw ca> Content-Type: text/plain; charset=utf-8; format=flowed On 2016-05-24 6:17 AM, Mitchell Lewis wrote:
