 connected to an interface

Basically what i want to do is to find out what is the mac address of a device plugged in to an interface on the switch (FastEthernet0/1 for example)
reading through the switch documentaion i found out that i can configure snmp trap on it to make it notify of any new mac address the switch detects by using the command 
snmp-server enable traps mac-notifiction
but for some reason my switch does not support this feature. the only options i see are
CORE_SWITCH(config)#snmp-server enable traps?
  c2900            Enable SNMP c2900 traps
  cluster          Enable Cluster traps
  config           Enable SNMP config traps
  entity           Enable SNMP entity traps
  hsrp             Enable SNMP HSRP traps
  snmp             Enable SNMP traps
  vlan-membership  Enable VLAN Membership traps
  vtp              Enable SNMP VTP traps
  <cr>

so the other way would be for me to run a cronjon on my gateway to poll the switch periodically using snmp to get new mac addresses
i have looked everywhere but cant seem to find the OID that would provide me this information.
any help i can get would me very much appreciated!
