There is a known problem with the Netmap on Windows. We thought we fixed this bug in NAV 3.5.1, but it appears to still be present for Windows users (oddly enough). We're working to find new fix, but it's puzzling that a bug in a platform agnostic Java program only appears on a specific platform... -- mvh Morten Brekkevold UNINETT

IP device Availability shown as "N/A"
by larskulseng＠gmail.com 20 Mar '09

20 Mar '09

We're using NAV 3.5 to monitor several IP devices, including switches and access points. Most devices report an availability in the form of a percentage, likely the percentage of uptime or successful ping responses. Some of our devices, (notably all of them switches), report a "last Day" availability of "N/A". My question is, how should "N/A" be interpreted? Some switches have no known downtime and are N/A, while other test switches are purposely disconnected and also show N/A. Does N/A mean that there has been no change in the given period? A small test showed that a test switch, when left off for 24 hours, gave availability of N/A for "last Day". Once this switch was turned on, N/A turned into a percentage. Shouldn't the availability always be a percentage? Thanks! Lars

network explorer issue
by sergemueller＠gmail.com 20 Mar '09

20 Mar '09

Hi everyone, i've got some strange issues with the network explorer in nav 3.5: it shows only the root node (our coreswitch) and its vlan interfaces. The Problem might occur because the coreswitch is a h3c switch, and h3c tends to index their physical interfaces starting from .4227614 going to 4228033 (52 ports) (for the first stack member and ports of the second stack are indexed from 503316505 to 503316913 the rest looks like this: IF-MIB::ifName.14 = STRING: NULL0 IF-MIB::ifName.16 = STRING: InLoopBack0 IF-MIB::ifName.31 = STRING: Vlan-interface1 IF-MIB::ifName.2431 = STRING: Vlan-interface301 IF-MIB::ifName.4023 = STRING: Vlan-interface500 IF-MIB::ifName.4031 = STRING: Vlan-interface501 IF-MIB::ifName.4227614 = STRING: Aux1/0/0 IF-MIB::ifName.4227625 = STRING: GigabitEthernet1/0/1 the last thing shown in the netexplorer is vlan-interface 501 then the whole tree is cut of. But in the network map you can see the topology, with some switches connected to our coreswitch (uplinks detected correctly) any suggestions where to look for this problem/how to fix? thx in advance

Announcement: NAV 3.5.1 released
by Morten Brekkevold 11 Mar '09

11 Mar '09

NAV 3.5.1 is now available for download at Launchpad: https://launchpad.net/nav/3.5/3.5.1 This is the first bugfix release of the 3.5 series; 23 reported bugs are fixed, details can be found in the changelog attached to this message. The most serious issues were that under certain conditions, alerts would be sent outside the configured timeperiods, or duplicate alerts would be sent, and there were crashes in the new ipdevinfo and useradmin tools related to organizations and rooms with spaces or dashes in their names. One change to the INSTALL documentation deserves mention: To be able to receive alerts via Jabber, the python module xmpp must be installed.

Seaching for IP/MAC-address
by Erik Weber 23 Feb '09

23 Feb '09

I've just installed NAV locally to get the Machine Tracker, however, I can only search for ip addresses when checking the Inactive field. Results doesn't contain the MAC address either.. Any idea why this is happening? We're running cisco layer 2/3 switches (added as GSW equipment). -- Erik
