Hello and happy new year!

Hello The Topo job does not work with Cisco VG350/K9 that I introduced in the GW category. I put the debugging and it remains blocked on the discovery of Vlan1. (see the log) I do not know if I'm missing MIBs or if it's a bug? Any ideas ? Thanks Biselx Nicolas

NAV snmptrapd handler help!
by Zhi-Wei Lu 14 Des '17

14 Des '17

Hi NAV gurus, I am in the process of learning how to use the snmptrapd handler for NAV. I hit a few road blocks along the way. I first test a simple home-made snmptrap (V1), what is the procedure to incorporate it into NAV snmptrapd. Where do I put the text mib files? /usr/share/snmp/mibs? Do I need to convert the text mib file into *.py in the directory (using smidump ?) /usr/share/pyshared/nav/smidumps ? I need to modify /etc/nav/snmptrapd.conf to add our own handler and put it in /usr/share/pyshared/nav/snmptrapd/handlers/ In my trap handler, I need to tell it process the trap with trap.genericType match what we define it. But I still could not get it to work properly. I would appreciate if someone can point me to the right direction, as I still miss a few pieces here and there. Thank you.

nav log time stamp issues: local time and UTC on different log files
by Zhi-Wei Lu 11 Des '17

11 Des '17

Hi NAV gurus, I noticed that some of the NAV log files use "local time" (here in California), 2017-12-07 15:56:13,973 [INFO] [nav.statemon.db] Returned 0 checkers while the other use UTC+1 in time stamp: 2017-12-08 00:50:14,898 [INFO] [nav.snmptrapd] Snmptrapd started, listening on 0.0.0.0:162, [::]:162 What do I need to make all log files using the local time stamp? Thank you. Zhi-Wei Lu IET-CR-Network Operations Center University of California, Davis (530) 752-0155

Netmap showing connections that do not exist anymore
by Oscar Patricio 08 Des '17

08 Des '17

Hi, I have been using NAV for quite some time and I am really satisfied with the tool. So much so, that I implemented it at my new job. That being said :) I have a question: the Netmap application is showing me connections that do not exist anymore. This means, they were once established, but have been disabled (I am talking about connections between two network switches, between which the cables have been removed and the interfaces have been shutdown) a couple of months ago. Because the network I am managing is not very big, this is not a big problem because I know those connections in the Netmap are "fake". This is, however, a bit annoying, and I would like the map to reflect the actual topology of the network. So my question is: is there any way that I can force a redrawing of the map? Or a way to force nav to delete that connection from its database? Thanks in advance!
