20.4  mac address-table max-mac-count 
Description 
The mac address-table max-mac-count command is used to configure the 
Port Security. To return to the default configurations, please use no  mac 
address-table max-mac-count  command.  Port Security is to protect the 
switch from the malicious MAC address attack by limiting the maximum 
number of the MAC addresses that can be learned on the port. The port with 
Port Security feature enabled will learned the MAC address dynamically. 
When the learned MAC address number reaches the maximum, the port will 
stop learning. Therefore, the other devices with the MAC address unlearned 
can not access to the network via this port. 
Syntax 
mac address-table max-mac-count { [ max-number 
num 
] [ mode { dynamic | 
static | permanent } ] [ status { forward | drop | disable } ] } 
no mac address-table max-mac-count [ max-number | mode | status ] 
Parameter 
num
  ——  The maximum number of MAC addresses that can be learned on 
the port. It ranges from 0 to 64. By default this value is 64. 
dynamic | static | permanent —— Learn mode for MAC addresses. There are 
three modes, including Dynamic mode, Static mode and Permanent mode. 
When Dynamic mode is selected, the learned MAC address will be deleted 
automatically after the aging time. When Static mode is selected, the learned 
MAC address will be out of the influence of the aging time and can only be
