Configuring and Monitoring Port Security
Port Security
Syntax: port-security (Continued)
clear-intrusion-flag
Clears the intrusion flag for a specific port. (See “Reading
Intrusion Alerts and Resetting Alert Flags” on page
13-33.)
no port-security <port-list> mac-address < mac-addr > [ <mac-addr>
<mac-addr> ]
Removes the specified learned MAC address(es) from the
specified port.
Retention of Static Addresses
Static MAC addresses do not age-out. MAC addresses learned by using
learn-
mode continuous
or
learn-mode limited-continuous
age out according to the
currently configured MAC age time. (For information on the
mac-age-time
command, refer to the chapter titled “Interface Access and System Informa­
tion” in the
Management and Configuration Guide for your switch.
Learned Addresses. In the following two cases, a port in Static learn mode
retains a learned MAC address even if you later reboot the switch or disable
port security for that port:
■ The port learns a MAC address after you configure the port for Static learn
mode in both the startup-config file and the running-config file (by exe­
cuting the
write memory
command).
■
The port learns a MAC address after you configure the port for Static learn
mode in only the running-config file and, after the address is learned, you
execute
write memory to configure the startup-config file to match the
running-config file.
To remove an address learned using either of the preceding methods, do one
of the following:
■ Delete the address by using
no port-security < port-number > mac-address
< mac-addr >
.
■ Download a configuration file that does not include the unwanted MAC
address assignment.
■ Reset the switch to its factory-default configuration.
Assigned/Authorized Addresses. : If you manually assign a MAC address
(using port-security < port-number > address-list < mac-addr > ) and then execute
write memory , the assigned MAC address remains in memory until you do one
of the following:
