Configuring Port-Based Traffic Control
How to Configure Port-Based Traffic Control
7.
switchport port-security [violation
{
protect | restrict | shutdown
|
shutdown vlan
}]
(Optional) Sets the violation mode, the action to be taken when a security
violation is detected, as one of these:
protect
—When the number of port secure MAC addresses reaches the
maximum limit allowed on the port, packets with unknown source
addresses are dropped until you remove a sufficient number of secure
MAC addresses to drop below the maximum value or increase the
number of maximum allowable addresses. You are not notified that a
security violation has occurred.
Note:
We do not recommend configuring the protect mode on a trunk port.
The protect mode disables learning when any VLAN reaches its maximum
limit, even if the port has not reached its maximum limit.
restrict
—When the number of secure MAC addresses reaches the limit
allowed on the port, packets with unknown source addresses are
dropped until you remove a sufficient number of secure MAC addresses
or increase the number of maximum allowable addresses. An SNMP trap
is sent, a syslog message is logged, and the violation counter
increments.
shutdown
—The interface is error-disabled when a violation occurs, and
the port LED turns off. An SNMP trap is sent, a syslog message is logged,
and the violation counter increments.
shutdown vlan
—Sets the security violation mode per VLAN. In this mode,
the VLAN is error disabled instead of the entire port when a violation
occurs.
Note:
When a secure port is in the error-disabled state, you can bring it out
of this state by entering the
errdisable recovery cause
psecure-violation
global configuration command. You can manually reenable it by entering the
shutdown
and
no shutdown
interface configuration commands or by using
the
clear errdisable interface vlan
privileged EXEC command.

switchport port-security
[
mac-address
mac-address
[
vlan
{
vlan-id
|
{
access
|
voice
}}]
(Optional) Enters a secure MAC address for the interface. You can use this
command to enter the maximum number of secure MAC addresses. If you
configure fewer secure MAC addresses than the maximum, the remaining
MAC addresses are dynamically learned.
Note:
If you enable sticky learning after you enter this command, the secure
addresses that were dynamically learned are converted to sticky secure MAC
addresses and are added to the running configuration.
(Optional)
vlan
—Sets a per-VLAN maximum value.
Enter one of these options after you enter the
vlan
keyword:
vlan-id
—On a trunk port, specifies the VLAN ID and the MAC address. If
you do not specify a VLAN ID, the native VLAN is used.
access
—On an access port, specifies the VLAN as an access VLAN.
voice
—On an access port, specifies the VLAN as a voice VLAN.
Note:
The
voice
keyword is available only if a voice VLAN is configured on a
port and if that port is not the access VLAN. If an interface is configured for
voice VLAN, configure a maximum of two secure MAC addresses.
