On
a
port
macAddressElseUserLoginSecureExt mode, intrusion protection is triggered only after both MAC
authentication and 802.1X authentication for the same frame fail.
Configuring Trapping
The trapping feature enables a device to send trap information in response to four types of events:
addresslearned: A port learns a new address.
dot1xlogfailure/dot1xlogon/dot1xlogoff: A port learns 802.1x authentication failure/successful
802.1x authentication/802.1x user logoff.
ralmlogfailure/ralmlogoff: A port learns MAC authentication failure/MAC authentication user
logoff.
intrusion: A port learns illegal frames.

Configuring Secure MAC Addresses
Secure MAC addresses are special MAC addresses. They never age out or get lost if saved before the
device restarts. One secure MAC address can be added to only one port in the same VLAN. Thus, you
can bind a MAC address to one port in the same VLAN.
Secure MAC addresses can be:
Learned by a port working in autoLearn mode.
Manually configured through the command line interface (CLI) or management information base
(MIB).
When the maximum number of secure MAC addresses is reached, no more can be added. The port
allows only the packets with the source MAC address being the secure MAC address.
Configuration Prerequisites
Enable port security
Set the maximum number of secure MAC addresses allowed on the port
Set the port security mode to autoLearn
