Hello all,
A little background:
I have been running NAV 4.7.1 for quite some time now. Every time I have tried to upgrade to 4.8.4, things get a little weird. Layer 2 topologies are miss-detected and certain sites show up as completely isolated from the rest of our WAN. Netmap does not show any layer 3 topology at all. Also the IPAM tool will not allow me to enter subnets as NAV has already detected previous prefixes.
So, today I decided to do a clean install of 4.8.4. I input only two sites of devices. The issue I now have is netmap does not show layer 2 topology of the two sites. I only see layer 3 of the two sites. We use HP procurve layer 3 switches.
I still do not see any bandwidth loads for any given VLAN's. Is this a known issue with NAV and HP procurves? I have never been able to see bandwidth loads on any VLANs from 4.7.1 to 4.8.4.
Thank you!

Hi William,

Alright, I have a bunch of questions in return :-)
- Do you have LLDP enabled on all your devices?
- Do you have a mix of LLDP and CDP?
- Do you run a heterogenous mix of device vendors, or is your network fairly homogenous in that regard?
- Have you read the topology troubleshooting guide? [1]
[1] https://nav.uninett.no/doc/4.8/howto/debugging-topology.html
Netmap does not show any layer 3 topology at all.
- So, if you check out the prefix report, there are no prefixes of the nettypes `link`, `elink` or `core`?
- Did NAV detect any of your link prefixes?
- How were they categorized?
Also the IPAM tool will not allow me to enter subnets as NAV has already detected previous prefixes.
What, precisely, do you mean by "entering a subnet" in IPAM?
I still do not see any bandwidth loads for any given VLAN's. Is this a known issue with NAV and HP procurves? I have never been able to see bandwidth loads on any VLANs from 4.7.1 to 4.8.4.
What is a VLAN bandwidth load, and how do you measure it? Are we talking about the octet/traffic counters of the router interface for the VLAN?
