platform is Windows VmWare
Perhaps this is yet resolved in a newer version but I could not find any hint for it...
Customer has configured User Tracking to discover endhosts on trunk ports. This is set globaly for all devices. Now we observe that switch_1
(2950) reports MAC addresseson one of his uplink-ports (gi0/2).
The switch_1 is connected to other cisco devices on gi0/1 and gi0/2; CDP is enabled on all devices; I do not see any problem here; Looking on the topology map I see only one neighbor device for switch_1 (on port gi0/1).
As far as I could see, the problem here is that the device connected on gi0/2 is managed by LMS with another IP then CDP reports is has. This is a known issue and the command "cdp source-interface" could help here if available in IOS. But it is not....
With debugging enabled for Data Collection, I see that the information about CDP neighbor devices is read correctly, i.e. neighbors are seen on both uplink-ports.
As far as I know, this process builts the "portsData.xml" file which is used by User Tracking to classify how each port needs to be treated. But in this file
gi0/2 is classified as an access port and not as a link port which leads to the observed problem.
Couldn't this be easily solved with a patch as Data Collection clearly sees a CDP neighbor device - so the port could be classified correctly - no matter if the neighbor device is managed by LMS or not!
Does this patch yet exists ? or istn't it that easy to implement?
