Hello, I'm using nav in a "simple" lab environment. I have a firewall (Juniper SRX3400) acting as GW/Router between Vlans that are distributed in some rooms thanks to switches (Cisco and Juniper). In particuler I have a direct fiber link between a Cisco 4948 (named 4948-Datacenter) and a Juniper QFX3500 (named QFX3500-DC). Port of Cisco is Te1/49 and port of QFX is xe-0/0/43 On the map and on the report, I see this on Direct neighborship candidates for 4948-datacenter: Sysname Interface source Candidate neighbor Candidate neighbor port control 4948-datacenter.sdn.lab Te1/49 lldp 3750-core.sdn.lab Gi1/0/24 4948-datacenter.sdn.lab Te1/50 lldp qfx3500-dc.sdn.lab xe-0/0/43.0

I see also this for qfx3500-dc: qfx3500-dc.sdn.lab xe-0/0/43.0 lldp 4948-datacenter.sdn.lab Te1/49

and this: 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/45 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/46 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/47 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/48 3750-core.sdn.lab Gi1/0/25 lldp 3750-ucs.sdn.lab Gi1/0/25

On the devices, I have not that (see end of messages). I suspect a mis interpretation of snmp get on the 4948 but cannot be sure :/ I've put everything in a file in case it's hard to see on the mail. How can we proceed to have the correct information? Thanks in advance, Sylvain
