Chapter 43 Commands for the Number
Limitation Function of Port, MAC in
VLAN and IP
43.1 switchport mac-address dynamic maximum
Command: switchport mac-address dynamic maximum <value>
no switchport mac-address dynamic maximum
Function: Set the max number of dynamic MAC address allowed by the port, and, at the same time,
enable the number limitation function of dynamic MAC address on the port; “no switchport
mac-address dynamic maximum” command is used to disable the number limitation function of
dynamic MAC address on the port.
Parameters: <value> upper limit of the number of dynamic MAC address of the port, ranging from 1 to
4096.
Default Settings: The number limitation function of dynamic MAC address on the port is disabled.
Command Mode: Port mode.
Usage Guide: When configuring the max number of dynamic MAC address allowed by the port, if the
number of dynamically learnt MAC address on the port is already larger than the max number of dynamic
MAC address to be set, the extra dynamic MAC addresses will be deleted. This function is mutually
exclusive to functions such as dot1x, MAC binding, if the functions of dot1x, MAC binding or TRUNK are
enabled on the port, this function will not be allowed.
Examples:
Enable the number limitation function of dynamic MAC address in port 1/2 mode, the max number to be
set is 20
Switch(config)#interface ethernet 1/2
Switch(Config-If-Ethernet1/2)# switchport mac-address dynamic maximum 20
Disable the number limitation function of dynamic MAC address in port 1/2 mode
Switch(Config-If-Ethernet1/2)#no switchport mac-address dynamic maximum
43.2 vlan mac-address dynamic maximum
Command: vlan mac-address dynamic maximum <value>
no vlan mac-address dynamic maximum
Function: Set the max number of dynamic MAC address allowed in the VLAN, and, at the same time,
enable the number limitation function of dynamic MAC address in the VLAN; “no ip mac-address
dynamic maximum” command is used to disable the number limitation function of dynamic MAC
address in the VLAN.
Parameters: <value> upper limit of the number of MAC address in the VLAN, ranging from 1 to 4096.
