I have 1 stack of 3 3750X switches.
BOOTLDR: C3750E Boot Loader (C3750X-HBOOT-M) Version 12.2(53r)SE1, RELEASE SOFTWARE (fc1)
I have a pc attached to switch 3 port 29 (g3/0/29)
interface GigabitEthernet3/0/29
switchport access vlan 900
switchport mode access
storm-control broadcast level 5.00
storm-control action trap
spanning-tree portfast
spanning-tree bpduguard enable
end
#show mac address-table int g3/0/29
Mac Address Table
-------------------------------------------
Vlan Mac Address Type Ports
---- ----------- -------- -----
900 2c44.fd1e.a672 DYNAMIC Gi3/0/29
Total Mac Addresses for this criterion: 1
Now, when I add port-security to this port, the mac address disappears.

Anyone have any ideas what might be happening? I have a different switch stack and everything works correctly. Different Code Version of course.
Thanks
Mike
