NAV and API exports
by Mischa Diehm 22 Jul '16

22 Jul '16

Hi, We are programming an inventory tool that uses NAV as one of its main datasources. We are now trying to get the Serial (lots of cisco here) for a given device. In the ipdevinfo overview we see the serial (for stacks there are even the stackmembers with serials listed). My questions is if we there is a way to get this information through the API and if yes how we could retrieve it? My second questions is if there is an easy documented way to extend the API with stuff like that or e.g. Status info like „is the box currently online“? Is there a roadmap towards what should and will be implemented regarding the exporsure through the API (maybe even write stuff?) Thanks a lot, Mischa -- Mischa Diehm | Network Team (NINS) UniBasel | IT-Services (ITS) Klingebergstr. 70 | CH-4056 Basel Tel. +41 61 267 1574 | https://its.unibas.ch

"Reversed" netmap view
by Kadlecsik József 07 Apr '16

07 Apr '16

Hi, Instead of the real topology ----------- gsw17a (SW) | kfki-sw (GSW) ---- gsw21 (SW) --- gsw21alag (SW) | ----------- gsw22a (SW) netmap shows a "reversed" topology, as shown in the attachment (full.png), i.e. gsw21 is the farthest from kfki-sw and gsw17a, gsw21alag, gsw22a "connect" gsw21 to kfki-sw. The IP device Neighbors of gsw21 shows the proper topology (gsw21.png) except that kfki-sw is not shown. The IP device Neighbors of gsw21alag shows the wrong topology: neighbor is kfki-sw instead of gsw21 (gsw21alag.png), the same true for gsw17a and gsw22a. The direct neighborship candidate is (partly) consistent with this (other fields are empty, non-related, invalid neighbors not listed): Sysname Interface source Candidate neighbor gsw17a 1/48 cam kfki-sw gsw21alag 1/24 cam kfki-sw gsw21 1/45 cam kfki-sw gsw21 1/107 cam gsw21alag gsw21 1/111 cam gsw17a gsw21 1/112 cam gsw22a gsw22a 1/48 cam kfki-sw kfki-sw Gi1/6 cam gsw17a kfki-sw Gi1/6 cam gsw21alag kfki-sw Gi1/6 cam gsw21 kfki-sw Gi1/6 cam gsw22a The switch types are: kfki-sw Cisco 6506-E gsw21 D-Link DSG-3120-48TC gsw17a D-Link DSG-3120-48TC gsw21alag D-Link DSG-3120-24TC gsw22a D-Link DSG-3120-48TC What can be wrong here?

Cisco - linux connection not recognized
by Kadlecsik József 07 Apr '16

07 Apr '16

Hello, We run nav 4.4.3 and are facing a strange problem: A Cisco 6500 (GW) ---- Linux with snmpd (GW) ---- B Cisco 6500 (SGW) Netmap shows that Linux - B Cisco are connected but does not show the connection between A Cisco - Linux. A Cisco IP Device Info, Neighbors does not list Linux. Linux IP Device Info, Neighbors lists neither A, nor B Cisco as neighbor. B Cisco IP Device Info, Neighbors lists Linux as neighbor. The Direct neighborship candidates does not list the connection between A Cisco and Linux. Linux has got IP addresses at both interfaces and added to the database with the IP address facing to B Cisco. We added the suggested interface descriptions to both Ciscos but it did not help. What could we do to get the connection recognized?

Portadmin - Problem with changing Vlan
by Mattias Söderholm 18 Mar '16

18 Mar '16

Hi. For a couple of week ago we could change Vlan in portadmin and save with our HP 5130 switches. But now with Nav 4.4.2 it only show error when saving. It says: Error setting vlan: SNMP Error: inconsistentValue (The set value is illegal or unsupported in some way). What can be the problem? There is error when we try to check connectivity for snmp for one of the switches via SeedDB also. That's because there's something wrong with Chassis detected. It got two Chassis detected and one is down. I have tried to delete the switch and added it again, but the N/A chassis is appearing after a while again! 5130-EI (serial: XXXXXXX, software: 7.1.045 Release 3109P05) <---- Down N/A (serial: N/A, software: 7.1.045) <--- Don't know where this comes from Regards Mattias

No. You should probably look into RANCID [1]. There was at some point some ideas to integrate RANCID and NAV, but the resources were never allocated. At UNINETT we extensively use tftp to store device configs, but storing a running config to the tftp serverr must be initiated from the device itself. RANCID is more proactive in this regard.

post installation question
by Don Click 29 Jan '16

29 Jan '16

Gents - first, thank you for an awesome tool to help manage the network. I recently did a fresh install of Debian and installed the NAV packages (including graphite). However, when we are adding our devices, they are all coming back with NO PORTS FOUND, or NO POWER SUPPLIES, NO FANS, etc. I am not seeing any logs in the /var/logs/nav area, so I am not sure what is really happening here. I have tried searching through the mail-list, but so far, I am not finding any possible suggestions or clues. When I evaluated the virtual appliance, this seemed to work quite well. (I wasn't able to get the virtual appliance to migrate to our production environment). Would someone be so kind as to point me in a direction that may help me troubleshoot this? Thank you!
