Pradip, I had the exact terminology wrong (it's "mac address-table notification mac-move") You haven't specified the platform(s) you were using but this may help point you in the right direction - http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/12.2_52_se/command/reference/cli1.html#wpmkr11902727which discusses setting thresholds etc.
If you want traps, you may specifically need to include "snmp-server enable traps mac-notification move" as well.
