Sorry I misspoke, I didn't mean to imply you had to, but clear the existing dynamic addresses, and see if it leaves it with a single mac.
I configured my switch N2024 with port security. For an interface Gi1/0/6 configuration looks like this: "SW-4#show run !System Software Version 6.7.1.4 .... interface Gi1/0/6switchport port-securityswitchport port-security dynamic 1switchport port-security mac-address stickyswitchport port-security mac-address sticky A81E.84FF.3D81 vlan 1switchport port-security mac-address sticky B07B.2530.A42A vlan 1switchport port-security mac-address sticky B07B.2530.A560 vlan 1exitswitchport port-security" On this interface I have: "switchport port-security dynamic 1". I don't understand why can I connect 3 different devices on this interface and all can work? I want to limit the number of source MAC addresses that can be learned on a port to only one. What im doing wrong ? Tomasz
Limit the number of source MAC address per port to one
