![]() ![]() you could write a JUNOScript that would do this. ![]() Juniper-nsp mailing list you enable LLDP on all your switches/devices. Even commercial IPAM systems often use ISC dhcpd in the background so it should be possible to get this working even if the ipam tool doesn't directly support this. It discovers the network based on snmp and lldp, starting from the default gw - or you can add network kit manually.Īgain it might be another tool that doesn't handle Juniper MIBs too well, but I think it's worth a shot.Īlso, if you use mostly DHCP and you have access / control over your DHCP infrastructure, you can track your hosts using DHCP snooping and option 82 - the forwarding kit will tell your DHCP server what each client is physically connected to (device, interface). Note that I have not used it with Juniper kit, but it should support at least some of it. Juniper-nsp mailing list previously used a great free network discovery / management tool called NeDi ( ) - supports multiple vendors, discovers network kit and hosts on the network, integrates with Cacti - really rich feature set. It at least 'gets it right' 90ish% of the time. Then connects the IP devices it found to the correct physical port on the EX switch visually on the map (also in a easy-to-copy table view)Ĭommercial software, but pretty nifty. Reads any ARP entries on any routers/switches to do the IP->MAC conversion/lookup. Looks at the MAC forwarding Table on the EX to see which MAC is out which physical port Gathers all the MAC addresses off your EX switches, Scans a Subnet to find all IP pingable/snmp poll-able devices in a range. Juniper-nsp mailing list does this as part of it's "Layer 2" discovery.
