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.
