I am also having issues with isolated nodes in netmap. I updated to 4.8.1, and now I have unconnected nodes.
The topology detection algorithm _did_ change in 4.8.1, as announced, so it is only expected that some issues would arise.
We'll have to conduct some internal tests, but I would like for you and Erik to provide more specific data.
When you know that device A and B are connected, but they do not appear as such in NAV, please do the following:
Please report the type of devices and the nature of the link between them.
Find the two interfaces you know to be linked (browse them in NAV/ipdevinfo). In the case of LACP/bonding, browse all the involved interfaces, physical and virtual, as it varies whether devices report topology information for the physical ports or the virtually bonded interfaces.
In the ipdevinfo "Connection" table, what appears as the connected IP device and port of these interfaces, and do they correspond to real life at all?
If they do not correspond to the real world, please click the "external link" symbol in the "To IP device" row. This will show you the report of topology candidate information found on this port by NAV. Please post an intact version of these reports, so we can see if there is any candidate data, and whether the data comes from CAM, CDP or LLDP.
(The point being that in any report about incorrect topology, we need a detailed report about the expected data vs. the actual data. Reports that amount to "it doesn't work" are more likely to be ignored on a busy day).
