43-2
Usage Guide: When configuring the max number of dynamic MAC allowed in the VLAN, if the number of
dynamically learnt MAC address in the VLAN is already larger than the max number to be set, the extra
dynamic MAC addresses will be deleted. After enabling number limitation function of dynamic MAC in the
VLAN, the number limitation of MAC is only applied to general access port, the number of MAC on
TURNK ports and special ports which has enabled dot1x, MAC binding function will not be limited or
counted.
Examples: Enable the number limitation function of dynamic MAC address in VLAN 1, the max number
to be set is 50.
Switch(config)#vlan1
Switch(Config-if-Vlan1)#vlan mac-address dynamic maximum 50
Enable the number limitation function of dynamic MAC address in VLAN 1
Switch(Config-if-Vlan1)#no vlan mac-address dynamic maximum
43.3 switchport arp dynamic maximum
Command: switchport arp dynamic maximum
no switchport arp dynamic maximum
Function: Set the max number of dynamic ARP allowed by the port, and, at the same time, enable the
number limitation function of dynamic ARP on the port; “no switchport arp dynamic maximum”
command is used to disable the number limitation function of dynamic ARP on the port.
Parameters: <value> upper limit of the number of dynamic ARP of the port, ranging from 1 to 4096.
Default Settings: The number limitation function of dynamic ARP on the port is disabled.
Command Mode: Port mode.
Usage Guide: When configuring the max number of dynamic ARP allowed by the port, if the number of
dynamically learnt ARP on the port is already larger than the max number to be set, the extra dynamic
ARP will be deleted. TRUNK ports do not supports this function.
Examples:
Enable the number limitation function of dynamic ARP in port 1/2 mode, the max number to be set is 20
Switch(Config-If-Ethernet1/2)#no switchport arp dynamic maximum
Switch(config)#interface ethernet 1/2
Switch(Config-If-Ethernet1/2)# switchport arp dynamic maximum 20
Disable the number limitation function of dynamic ARP in port 1/2 mode
Switch(Config-If-Ethernet1/2)#no switchport arp dynamic maximum
43.4 switchport nd dynamic maximum
Command: switchport nd dynamic maximum
no switchport nd dynamic maximum
Function: Set the max number of dynamic NEIGHBOR allowed by the port, and, at the same time,
