vlan
vlan-id
: Specifies the VLAN to which the secure MAC address belongs. The value range for the
vlan-id
argument is 1 to 4094.
Usage guidelines
Secure MAC addresses are MAC addresses configured or learned in autoLearn mode, and if saved,
can survive a device reboot. You can bind a secure MAC address only to one port in a VLAN.
You can add important or frequently used MAC addresses as sticky or static secure MAC addresses
to avoid the secure MAC address limit causing authentication failure. To successfully add secure
MAC addresses on a port, first complete the following tasks:
•
Enable port security on the port.
•
Set the port security mode to autoLearn.
•
Configure the port to permit packets of the specified VLAN to pass or add the port to the VLAN.
Make sure the VLAN already exists.
Sticky MAC addresses can be manually configured or automatically learned in autoLearn mode.
Sticky MAC addresses do not age out by default. You can use the
port-security timer autolearn
aging
command to set an aging timer for the sticky MAC addresses. When the timer expires, the
sticky MAC addresses are removed.
Static secure MAC addresses never age out unless you perform the following operations:
•
Remove these MAC addresses by using the
undo port-security mac-address security
command.
•
Change the port security mode.
•
Disable the port security feature.
You cannot change the type of a secure address entry that has been added or add two entries that
are identical except for their entry type. For example, you cannot add the
port-security
mac-address security sticky 1-1-1 vlan 10
entry when a
port-security mac-address security
1-1-1 vlan 10
entry exists. To add the new entry, you must delete the old entry.
Examples
# Enable port security, set Ten-GigabitEthernet 1/0/1 to operate in autoLearn mode, and configure
the port to support a maximum number of 100 secure MAC addresses.

# Specify MAC address 0001-0002-0003 in VLAN 4 as a sticky MAC address.

# In system view, specify MAC address 0001-0001-0002 in VLAN 10 as a secure MAC address for
