We observe a WS-C93XX (Catalyst 93xx Switch Stack from cisco) where for some MAC-addresses information about switch port is missing.
Sorry, you kind of lost me here. Are you saying there are CAM records from this switch stack available in Machine Tracker, but that these records have no interface names attached to them?
Yep.
If so, can you confirm that NAV does not list any nameless interfaces on these switches (using e.g. the interfaces report)?
Example lines from the database:
nav=> select netboxid,ifindex,port,mac,start_time,end_time from cam where netboxid='5802'; netboxid | ifindex | port | mac | start_time | end_time ----------+---------+----------+-------------------+--------------------------- -+---------------------------- 5802 | 279 | | 6c:4b:90:1d:7d:a1 | 2019-01-18 10:13:00.577658 | infinity
We know that the device with MAC 6c:4b:90:1d:7d:a1 is connected to Gi3/0/15
nav=> select interfaceid,netboxid,moduleid,ifindex,ifname,ifdescr,iftype from interface where netboxid='5802' and interfaceid='2266190'; interfaceid | netboxid | moduleid | ifindex | ifname | ifdescr | iftype -------------+----------+----------+---------+----------+---------------------- -+-------- 2266190 | 5802 | | 279 | Gi3/0/15 | GigabitEthernet3/0/15 | 6
The box has no nameless interfaces.
