NOTE:
On a port operating in either macAddressElseUserLoginSecure mode or
macAddressElseUserLoginSecureExt mode, intrusion protection is triggered only after both MAC
authentication and 802.1X authentication fail for the same frame.
Configuring secure MAC addresses
Secure MAC addresses are configured or learned in autoLearn mode. If the secure MAC addresses are
saved, they can survive a device reboot. You can bind a secure MAC address only to one port in a
VLAN.
When the maximum number of secure MAC address entries is reached, the port changes to secure mode.
In secure mode, the port cannot add or learn any more secure MAC addresses. The port allows only
frames sourced from secure MAC addresses or MAC addresses configured by using the
mac-address
dynamic
or
mac-address static
command to pass through.
Secure MAC addresses include static, sticky, and dynamic secure MAC addresses.
