index-value
: Specifies the OUI index in the range of 1 to 16.
Usage guidelines
An OUI, the first 24 binary bits of a MAC address, is assigned by IEEE to uniquely identify a device
vendor. Use this command when you configure a device to allow packets from certain devices to
pass authentication. For example, when a company allows only IP phones of vendor A in the Intranet,
use this command to set the OUI of vendor A.
Examples
# Configure an OUI value of 000d2a, setting the index to 4.

Description
autolearn
autoLearn
In this mode, a port can learn MAC addresses, and
allows frames sourced from learned or configured the
MAC addresses to pass. The automatically learned MAC
addresses are secure MAC addresses. You can also
configure secure MAC addresses by using the
port-security mac-address security
command. A
secure MAC address never ages out by default. In
addition, you can configure MAC addresses manually by
using the
mac-address dynamic
and
mac-address
static
commands for a port in autoLearn mode.
When the number of secure MAC addresses reaches the
upper limit set by the
port-security max-mac-count
command, the port changes to secure mode.
mac-authentication
macAddressWithRad
ius
In this mode, a port performs MAC authentication for
users and services multiple users.
