Hello everybody,
I have a strange and very annoying problem on a switch 3750-48TS with IOS 12.2(40)SE.
On each port I have :
switchport mode access
switchport port-security
switchport port-security mac-address xx..
But on one port which was in use before, I am trying to configure it again and at the stpe to put the mac address I have the follwing message :
"total secure mac-addresses on interface Fastethernet 5/0/35 has reached maximum limit"
When I am checking the portsecurity address table it is empty foiar that port, and also empty in "show mac address-table..." for that port.
I have of course use the "no switchport.." commands but nothing change.
Someone has an idea ?
Thank you.

Have you tried taking all the port-security commands off and reapplying? I've seen a similar issue where changing the switchport port-security mac-address xx line didn't work, and the only way to get it working was removing all the lines relating to security.

Hi,
I have tried to remove all command for port-security for that interface, but nothing. For the full stack I can't (5 switches in the stack with about 130 people)
I have used a workaround so far by setting a maximum number to 5 which is I know higher than needed. And it is working so far.
Really strange problem.
