Jeremy,

We use port security along with mac-notification on our Cisco 3560's
[running 12.2(40)SE] without a problem. I'd be curious as to what
problems you have seen using the two together.

Sample config:

interface FastEthernet0/10
 switchport access vlan <auth vlan>
 switchport mode access
 switchport port-security
 switchport port-security aging time 2
 switchport port-security violation restrict
 switchport port-security aging type inactivity
 ip arp inspection limit rate 15 burst interval 10
 snmp trap mac-notification change added
 no cdp enable
 spanning-tree portfast
 spanning-tree bpduguard enable
 ip verify source
 ip dhcp snooping limit rate 50
!


Thanks,
