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

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

Instance is now set to nothing?

Hello, I don’t know the root of this problem, but I seem to have a module that has either been switched or replaced that is generating a load of error messages in /var/log/nav/cricket/normal.log.
