I have Cisco catalyst 3560 SW PoE-24, i'm using this switch as testing for port security. The installed IOS Version is 12.2(40)SE.
I'm applying the following commands to the interface one after one for testing, and i'm connected my laptop to the Cisco IP Phone and trying the Cisco IP Phone to port after port at the switch.
The strange issue is that some ports are working fine and others are not "Security violation occurred". Why that?
The commands that applied to all interfaces:
switchport port-security maximum 2
switchport port-security violation restrict
switchport port-security mac-address sticky
Thanks in advance
