netgraphp

A php script which uses lldp information to traverse snmp servers in a network and produce a graphical map of different hosts and connections in the network. The graph is produced with the graphviz dot syntax and graphviz can be used to produce different file formats like .png or .eps. All connections to be identified must have snmp servers with lldp support at both ends. Most high end switches have built in support for snmp and lldp. Computer hosts need something like lldpd together with an snmp server.
