I thought I should give NAV a tryout in a large service provider network. After some initial problems fetching the device information for some devices (had to remove the OSPF oid) I was finally up and running. I had to add all my device types but that was easily done (I have mostly Cisco 7600 and 7300 series devices). However, NAV has a huge problem trying to figure out which module each port belongs to (especially the 10Gb ports). Attached is a device info screen grab of one of my modules (module 5), and as you can see NAV things the module has ports from module 1, 2, 4 (and 5) as well as loopbacks and vlans. Other parts of NAV seems to get things correct (the explorer) however because of these problems they can't detect where the port connects to (link type "none"). Which sadly makes NAV useless. Is there a way I can fix this?
Whenever the device info is able to pinpoint which module the port belongs to it is also able to detect the device the port connects to (including the 10Gb ports). However, that seems to be the exception and not the rule.
FYI, the screen grab is from a 7609 running SRD1.
