Not sure if we are talking about the port aging here.
But 3550 will allow you to set multiple mac addresses
under port security. For example:
interface FastEthernet0/1
switchport access vlan 16
switchport mode access
switchport port-security
switchport port-security maximum 5
switchport port-security mac-address 0001.0001.0002
switchport port-security mac-address 0001.0001.0004
switchport port-security mac-address 0001.0001.0005
switchport port-security mac-address 0001.0002.0003
