Configuring and Monitoring Port Security
Port Security
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.
Syntax:
port-security
(Continued)

no port-security
<port-list>

mac-addr
> [
<mac-addr>
<mac-addr>
]
Removes the specified learned MAC address(es) from the
specified port.
