Description
In this mode, the learned MAC addresses will
change to Security MAC addresses.
This security mode will automatically change to
the secure mode after the number of Security
MAC addresses from this port has reached that
configured with the port-security max mac
count command.
After this, new Security MAC address cannot be
added. Only the packets whose source MAC
address is the Security MAC address can pass the
port.
In this mode, the system is disabled from learning
MAC addresses from this port.
Only the packets whose original MAC addresses
are the configured static MAC addresses can pass
the port.
In this mode, port-based 802.1x authentication is
performed for connected users.
