Purpose
(Optional) Enter 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.
If you enable sticky learning after you enter this command, the secure
Note
addresses that were dynamically learned are converted to sticky
secure MAC addresses and are added to the running configuration.
(Optional) vlan—set a per-VLAN maximum value.
Enter one of these options after you enter the vlan keyword:
vlan-id—On a trunk port, you can specify 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, specify the VLAN as an access VLAN.
•
voice—On an access port, specify the VLAN as a voice VLAN.
•
The voice keyword is available only if a voice VLAN is configured on
Note
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.
(Optional) Enable sticky learning on the interface.
(Optional) Enter a sticky secure MAC address, repeating the command as
many times as necessary. If you configure fewer secure MAC addresses than
the maximum, the remaining MAC addresses are dynamically learned, are
converted to sticky secure MAC addresses, and are added to the running
configuration.
If you do not enable sticky learning before this command is entered,
Note
an error message appears, and you cannot enter a sticky secure MAC
address.
(Optional) vlan—set a per-VLAN maximum value.
Enter one of these options after you enter the vlan keyword:
vlan-id—On a trunk port, you can specify 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, specify the VLAN as an access VLAN.
•
voice—On an access port, specify 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.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
