[c-nsp] Unicast flooding on 6500 with dcef

I'm having an issue with unicast traffic being flooded on a 6500 with dcef.
All the traffic being flooded is to a single mac-address and if i check the
cam table for that mac-address I only see an entry on one of the modules
with dcef but not on the others. The command 'mac-address-table
synchronize' does not seem to be available in the version of code this
device is running. Anyone have any idea if there is another way of fixing
this without upgrading the code or configuring a static cam entry?


show mac-add add 0010.dbff.22d0 all
Legend: * - primary entry
        age - seconds since last seen
        n/a - not available

  vlan   mac address     type    learn     age              ports
