• dot1xlogfailure/dot1xlogon/dot1xlogoff—802.1X authentication failure, success, and 802.1X
user logoff.
• ralmlogfailure/ralmlogon/ralmlogoff—MAC authentication failure, MAC authentication user
logon, and MAC authentication user logoff.
• intrusion—Detection of illegal frames.

Command Remarks
1. Enter system view.
system-view N/A
2. Enable port
security traps.
port-security trap { addresslearned | dot1xlogfailure

By default, port security
traps are disabled.
Configuring secure MAC addresses
Secure MAC addresses are configured or learned in autoLearn mode and can survive link down/up
events. You can bind a secure MAC address to only one port in a VLAN.
IMPORTANT:
W
hen the maximum number of secure MAC address entries is reached, the port chan
g
es to secure mode,
and no more secure MAC addresses can be added or learned. The port allows only frames sourced from
a secure MAC address or a MAC address configured by using the mac-address dynamic or mac-address
static command to pass through.
Secure MAC addresses are divided into static, sticky, and dynamic secure MAC addresses.

Static Manually added
Not available.
They never age out unless you manually remove
them, change the port security mode, or disable
the port security feature.
Yes.
Sticky
Manually added,
converted from
dynamic secure MAC
addresses, or
automatically learned
when the dynamic
secure MAC function
(port-security
mac-address
dynamic) is disabled.
Sticky MAC addresses by default do not age
out, but you can configure an aging timer or use
the aging timer together with the inactivity aging
function to delete old sticky MAC addresses:
• If only an aging timer is configured, the
aging timer counts up regardless of whether
traffic data has been sent from the sticky
MAC address.
• If both an aging timer and the inactivity
aging function are configured, the aging
timer restarts once traffic data is detected
from the sticky MAC address.
Yes.
The secure MAC aging
timer restarts at a
reboot.
