Troubleshoot Management Connectivity on a Data Interface
Capture packets on the FTD internal interface
At the FTD CLI, capture packets on the internal backplane interface (nlp_int_tap) to see if management
packets are being sent:
capture name interface nlp_int_tap trace detail match ip any any
show capturename trace detail
Check the internal interface status, statistics, and packet count
At the FTD CLI, see information about the internal backplane interface, nlp_int_tap:
show interace detail
> show interface detail

Check routing and NAT
At the FTD CLI, check that the default route (S*) was added and that internal NAT rules exist for the
Management interface (nlp_int_tap).
