Configuring MLS
Flow Mask Mode and show mls entry Command Output
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

With the source-destination-ip flow mask, the protocol, source port, and destination port fields display
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 source-destination-ip mode:
Console> (enable) show mls entry ip short

shown for each flow.
