Enabling port security traps
You can configure the port security module to send traps for the following categories of events:
•
addresslearned
—Learning of new MAC addresses.
•
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.
To enable port security traps:

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:
When the maximum number of secure MAC address entries is reached, the port changes 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 fall into static, sticky and dynamic secure MAC addresses.
