Configuring and Monitoring Port Security
MAC Lockdown
You cannot perform MAC Lockdown and 802.1x authentication on the same port or on the same MAC address. MAC Lockdown and 802.1x authentication are mutually exclusive.
Lockdown is permitted on static trunks (manually configured link aggrega- tions).
Differences Between MAC Lockdown and Port Security
Because
Port security maintains a list of allowed MAC addresses on a
MAC Lockdown, on the other hand, is not a “list.” It is a global parameter on the switch that takes precedence over any other security mechanism. The MAC Address will only be allowed to communicate using one specific port on the switch.
MAC Lockdown is a good replacement for port security to create tighter control over MAC addresses and which ports they are allowed to use (only one port per MAC Address on the same switch in the case of MAC Lockdown). (You can still use the port for other MAC addresses, but you cannot use the locked down MAC address on other ports.)
Using only port security the MAC Address could still be used on another port on the same switch. MAC Lockdown, on the other hand, is a clear
The switch does not allow MAC Lockdown and port security on the same port.
