NAV with Cisco 3850
by Mischa Diehm 15 Sep '23

15 Sep '23

Hi, we have a 3850 Stack with 3x ES-C3850-48T-S and 5x WS-C3850-12X48U. When we try to PortAdmin and edit a Port we get (see also attached Jpg): „IP device found but has no type“ Any ideas?

How to add "Getting started" widget
by Ingeborg Hellemo 01 Mar '18

01 Mar '18

I seem to have removed the "Getting started with NAV" widget from det default user, and now new users miss the opportunity to take the 30 second tour. How do I add this? I can't find it in the widgets menu. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Is that a healthy carbon cache?
by Karl Gerhard 01 Mar '18

01 Mar '18

Hello, we're having problems with gaps in graphs (only for some interfaces) and I'm working through the https://nav.uninett.no/doc/4.8/faq/graph_gaps.html guide. I've arrived at the part with the "Carbon Cache" and I'd like to know whether those two graphs represent a healthy state: http://abload.de/img/e7zassl.png http://abload.de/img/jyz3sjf.png What strikes me as odd is that there are negative numbers, I can't see that on the graph on https://nav.uninett.no/doc/4.8/faq/graph_gaps.html Best regards Karl

Business report - linkDown, erroneous listings
by Ingeborg Hellemo 15 Feb '18

15 Feb '18

The business report for Link Availability are supposed to show links that are expected to be up but are experiencing downtime. Links that have never been up or that are down and the linkDown alert is acknowledged/cleared will not show up here. Have I understood this correctly? We now have a handful of links which have been down "forever", but NAV did at some point last Friday decide that the links were up, ended the linkDown status and shows the links in the business report with nn% downtime. All these links are still down and NAV thinks the link is Inactive. (It is possible that the NAV processes including ipdevpoll was restarted at the point the error was introduced) How can we clean up this mess and remove the links from the business report? --Ingeborg
