43-3
enable the number limitation function of dynamic NEIGHBOR on the port; “no switchport nd dynamic
maximum” command is used to disable the number limitation function of dynamic NEIGHBOR on the
port.
Parameters: <value> upper limit of the number of dynamic NEIGHBOR 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 NEIGHBOR allowed by the port, if the
number of dynamically learnt NEIGHBOR on the port is already larger than the max number to be set, the
extra dynamic NEIGHBOR will be deleted. TRUNK ports do not supports this function.
Examples:
Enable the number limitation function of dynamic NEIGHBOR in port 1/2 mode, the max number to be
20.
Switch(config)#interface ethernet 1/2
Switch(Config-If-Ethernet1/2)# switchport nd dynamic maximum 20
Disable the number limitation function of dynamic NEIGHBOR in port 1/2 mode
Switch(Config-If-Ethernet1/2)#no switchport nd dynamic maximum
43.5 ip arp dynamic maximum
Command: ip arp dynamic maximum
no ip arp dynamic maximum
Function: Set the max number of dynamic ARP allowed in the VLAN, and, at the same time, enable the
number limitation function of dynamic ARP in the VLAN; “no ip arp dynamic maximum” command is
used to disable the number limitation function of dynamic ARP in the VLAN.
Parameters: <value> upper limit of the number of dynamic ARP in the VLAN, ranging from 1 to 4096.
Default Settings: The number limitation function of dynamic ARP in the VLAN is disabled.
Command Mode: Interface Configuration Mode.
Usage Guide: When configuring the max number of dynamic ARP allowed in the VLAN, if the number of
dynamically learnt ARP in the VLAN is already larger than the max number to be set, the extra dynamic
ARP will be deleted.
Examples:
Enable the number limitation function of dynamic ARP in VLAN 1, the max number to be set is 50
Switch(config)#interface ethernet
Switch(Config-if-Vlan1)# ip arp dynamic maximum 50
Disable the number limitation function of dynamic ARP in VLAN 1
Switch(Config-if-Vlan1)#no ip arp dynamic maximum
