Find lldp informations using snmpwalk or another method

I want to build a java tool that extracts lldp informations of some devices (switches, routers, etc) to make a 'topology map'.

Trying snmpwalk, i found only useless informations (for this case). I think lldp mib is 1.0.8802.1.1.2, but i'm not sure.

Anyone knows how to extract this, using snmpwalk or another method?

开发者_如何学运维Thanks in advance.

According to IEEE 802 MIB document, what append when you try to walk on this OID :

1.0.8802.1.1.2.1

I stands for :

iso std(0) iso8802(8802) ieee802dot1(1) ieee802dot1mibs(1) lldpMIB(2) lldpObjects(1)

This can be done via SNMPWALK. IF-MIB/IP-MIB are the generic MIBs that will provide you with good enough data to build something like that. If its just for Cisco than CDP-MIB will give you everything that you would need. Let me know if you are trying to make something vendor neutral.
