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

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
