snmpwalk (cisco mibs) - changes in the interface's MAC addresses table

[magic_rooter]

Is there any OID (if it's possible the exact name) in cisco mibs which
shows  changes in the    interface's  MAC addresses table? (Or if
there is no such OID, maybe there is OID with the STATIC interface's
MAC addresses table?)
With the help of snmpwalk with such OID to our cisco devices  and with
some kind of script for Nagios I will find out the changes in my
network status.
I have found something on Cisco site
http://tools.cisco.com/Support/SNMP/do/BrowseMIB.do?local=en&step=2&submitClicked=true&mibName=CISCO-MAC-NOTIFICATION-MIB#dependencies

"This MIB module is for configuration of the MAC notification feature.
MAC notification is a mechanism to inform monitoring devices when
there are MAC addresses learnt or removed from the forwarding database
of the monitored devices."

Maybe this MIB is what I need?
