Topo doesn't work with Cisco VG350
by Biselx Nicolas 03 Jan '18

03 Jan '18

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 Dec '17

14 Dec '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 Dec '17

11 Dec '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 Dec '17

08 Dec '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!

New to NAV, supported devices
by Vinsonnaud Ludovic 07 Dec '17

07 Dec '17

Hello, Sorry about my english, I'm french so everything may not be understood :-) I'm new to NAV and this software seems very interesting for my needs. I'm managing the network in an Engineer School (IOGS) and CNRS Labs (LCF and LP2N) based in 2 sites (near Paris and near Bordeaux). I've got an heterogeneous group of switches because we begin to change our 100Mb switches by 1Gb and 10Gb ones. For the moment we own : - Dell S4048-ON (force10) used for routing - Dell N2048 - Dell N4064 - Cisco 2960s - Cisco 3750 My switches are recognized pretty well after some tweaking. For Cisco 2960, everything works. Sometimes I've got timeout and "failed" changes so I need to wait before trying again (especialy vlan change). For Cisco 3750, it's the same For Dell N2048, I'm a bit confused because if I have this command "switchport access vlan 524" already set in the switch and I ask to change the vlan from 524 to 525 with NAV, it adds this command "switchport general pvid 525" but doesn't delete the old one. So why change a "switchport access" by a "switchport general" ? Is it better to have a "switchport mode general" in default config ? Switchport mode access is the default mode, the 2 combined commands will not work as intended I think ? I've not yet tested S4048 and N4064. -- Regards, IOGS Logo <https://www.institutoptique.fr> *Ludovic Vinsonnaud * - Ingénieur Réseau basé à Bordeaux, bureau F108 (IOA, Rue François Mitterrand, 33400 Talence) *Institut Optique Graduate School* 2 Avenue Augustin Fresnel - 91127 PALAISEAU Cedex Tel. +33 5 57 01 71 52 - Mob. +33 6 08 08 41 05
