NDE Flowmask is configured to use at least Null flowmask
Console>
Console> show mls flowmask
The MSFC features are using VlanFullFlowOnly flow mask on vlan(s) 13.

Flow Mask Modes and show mls entry Command Outputs
With the destination-ip flow mask, the source IP, protocol, and source and destination port fields show
the details of the last packet that was Layer 3 switched using the MLS cache entry.
This example shows how the show mls entry command output appears in destination-ip mode:
Console> (enable) show mls entry ip short
