Hi,
I try to connect between routers and switches within our network so I can view it in Netmap view on the toolbox. I've read the guides in http://metanav.uninett.no/subnetsandvlans#guide_lines_for_configuring_router.... I've create the vlan and change the description on the routers and switches to match the requirement based on the guidelines.
However, I'm unable to connect the routers and switches on the netmap. The devices on the netmap are not connected and seems like "flying" on it's own and hard to capture to view all devices at the same time. Could you give me a hint, for example how to connect between two devices and view it correctly on the netmap view.
Thanks.
Regards Royke

Hi,
Correction, the connection view in netmap is established now. But I think I found a bugs (or is it a feature ?). My Prefix definition is dissapear , but my Vlan seems automagically filled with lot of Nettypes definition namely : core, elink, vlan. I think it is a normal behaviour, is it or not ?
Also I found many error from ipdevpoll.log like below (cannot paste all but I paste the most important parts I think) :

I'm not sure what you're referring to here? What prefix definition has disappeared?
NAV autodetects your prefixes from your routers. The only prefixes you'll need to add yourself are "scope" and "reserved" prefixes.
A "scope" prefix is an indication of what network address would encompass your entire network (though you may add multiple scopes if your delegated network block addresses vary wildly). The scope prefix is only used for things such as the graphical network scope report, which shows you your subnet allocations and utilization.
A "reserved" prefix is a prefix you do not route, or which is routed by something you aren't monitoring with your NAV. They can be added just to designate them as such in the scope report mentioned above.
As for the prefixes/vlans autodiscovered by NAV, NAV will try to classify each as either "link", "elink", "core" or "lan".
I believe all these are described adequately at the Wiki page you already referred to, http://metanav.uninett.no/subnetsandvlans#network_types .
Also I found many error from ipdevpoll.log like below (cannot paste all but I paste the most important parts I think) :

Looks like a bug in the handling of devices that have been physically replaced. The rest of your errors may be caused by the same problem, since this seems to create some scheduling problem for the duration of the ipdevpoll process.
If you would report these error messages at https://bugs.launchpad.net/nav/+filebug I would be gratefaul :)

I refering to link in (http://metanav.int.cbn.net.id/seeddb/prefix/). I already fill the prefix with the subnet of the point-to-point link between routers and switches of the network. Then change the description of the interface. And suddenly the prefix dissapear. I guess the autodetected vlan prefix superseed the prefix I already fill in the prefix tab and filling the vlan (http://metanav.int.cbn.net.id/seeddb/vlan/) with the network type aforementioned.

Yes , it explained a lot.

Ok, I think you may be confusing things (and I think this is confusing about the SeedDB interface as well).
You can only add/edit prefixes of type `scope` and `reserved`. There is no point in adding point-to-point link prefixes, because these are neither `scope` nor `reserved`, they are `link` prefixes. These will be automatically collected from your routers by NAV.
What happened here is that NAV found your point-to-point link's prefix in your router, and re-classified it to a `link` type prefix. That's why it looks like it disappeared from SeedDB - it is no longer editable there, since it is now part of NAV's collected information.
If you want to see the full list of known prefixes, you should view the Prefix report in the report tool.

Please be aware that the Netmap shows your layer 3 topology by default (everything else can be gotten from the dropdown menus).
Once your topology changes (or you otherwise change your device configuration as describe in your post), it may take some time for NAV to discover the changes and calculate a new topology.
