By default, a port operates in
noRestriction mode. In this
mode, access to the port is not
restricted.
You can set a port security
mode as needed.
z Before setting the port security mode to autolearn, you need to set the maximum number of MAC
addresses allowed on the port with the port-security max-mac-count command.
z When the port operates in the autoLearn mode, you cannot change the maximum number of MAC
addresses allowed on the port.
z After you set the port security mode to autolearn, you cannot configure any static or blackhole
MAC addresses on the port.
z If the port is in a security mode other than noRestriction, before you can change the port security
mode, you need to restore the port security mode to noRestriction with the undo port-security
port-mode command.
