Navtopology Difficulties and VLAN Bandwidth load
by William Daly - Network Specialist, VUSD Technology 30 May '18

30 May '18

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! William Daly Network Specialist Vacaville Unified School District (707) 453-6170

netmap and lag
by Zhi-Wei Lu 09 May '18

Hi NAV gurus, We have a very limited test envioronment for NAV, our environment are Foundry based (->Brocade-> Arris and Extreme now). We have enabled lldp on edge switches, but not on ALL upstream routers. Even on connections with lldp on, the map does not show LAG ports correctly, it seems. Is there a manual way to fix netmap problem for those it fails to correctly identify the connections? Thank you.

Sizing the NAV server
by Zhi-Wei Lu 09 May '18

Hi NAV gurus, I have been testing NAV on and off for a while with a fraction of our devices on a small VM. I like it more and more as I am getting used to it. I would like to get recommendation of a NAV setup that can handle our environment. Our network is layered like the following: Border Router: 2 Core and Area Router: ~30 Building Router: ~100 Edge Switch: ~1500 Shall we use one big server or multiple servers, physical or virtual for various NAV management components? What CPU, MEMORY, DISK IO, and DISK size shall we plan for? Thank you very much for your help. Zhi-Wei Lu IET-CR-Network Operations Center University of California, Davis (530) 752-0155
