VLAN of the entry is removed or the port are removed from the VLAN, or port security is
disabled on the port where the address resides.
deleteontimeout - The locked addresses can be aged out after aging timer expires.
deleteonreset - This address will be removed if the switch is reset or reboots. The cases
under which the permanent entries are deleted also apply to the deleteonreset entries
vlan - (Optional) Specify the VLAN to limit the address learning.
<vlan_name 32> - Specify the name of the VLAN. The maximum length is 32 characters.
vlanid - Specify a list of VLANs by VLAN ID to limit the address learning.
<vidlist> - Specify a list of VLAN ID.
max_learning_addr - (Optional) Specify the maximum of MAC address entries that can be
learned on this port. If the value is set to 0, it means that no user can get authorized by the
port security function on this port. If the setting is smaller than the number of current learned
entries on the port, the command will be rejected. The default value is 32.
<max_lock_no 0-3328> - Specify the value between 0 and 3328.

Description
This command is used to set the maximum number of MAC address entries that can be authorized
system wide. There are four levels of limitations on the learned entry number, for the entire system,
for a port, for a VLAN, and for specific VLAN on a port. If any limitation is exceeded, the new entry
will be discarded. The setting for system level max learned users must be greater than the total of
the max learned users allowed on all ports.
