HP 5920 Command Reference Manual page 138

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 them. When the timer expires, the sticky MAC addresses are
removed.
Static secure MAC addresses never age out unless you remove them by using the undo port-security
mac-address security command, changing the port security mode, or disabling 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 port Ten-GigabitEthernet 1/0/1 in autoLearn mode, and set the maximum
number of secure MAC addresses allowed on the port to 100.
<Sysname> system-view
[Sysname] port-security enable
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] port-security max-mac-count 100
[Sysname-Ten-GigabitEthernet1/0/1] port-security port-mode autolearn
# Specify MAC address 0001-0002-0003 in VLAN 4 as a sticky MAC address.
[Sysname-Ten-GigabitEthernet1/0/1] port-security mac-address security sticky
0001-0002-0003 vlan 4
[Sysname-Ten-GigabitEthernet1/0/1] quit
# In system view, specify MAC address 0001-0001-0002 in VLAN 10 as a secure MAC address for port
Ten-GigabitEthernet 1/0/1.
[Sysname] port-security mac-address security 0001-0001-0002 interface
