through configuration commands.

Limiting the number of dynamic MAC and IP of ports:

1. Limiting the number of dynamic MAC. If the number of dynamically learnt MAC address by the switch is

already larger than or equal with the max number of dynamic MAC address, then shutdown the MAC

study function on this port, otherwise, the port can continue its study.

2. Limiting the number of dynamic IP. If the number of dynamically learnt ARP and ND by the switch is

already larger than or equal with the max number of dynamic ARP and ND, then shutdown the ARP and

ND study function of this port, otherwise, the port can continue its study.

Limiting the number of MAC, ARP and ND of interfaces:

1. Limiting the number of dynamic MAC. If the number of dynamically learnt MAC address by the VLAN of

the switch is already larger than or equal with the max number of dynamic MAC address, then shutdown

the MAC study function of all the ports in this VLAN, otherwise, all the ports in this VLAN can continue

their study (except special ports).

2. Limiting the number of dynamic IP. If the number of dynamically learnt ARP and ND by the switch is

already larger than or equal with the max number of dynamic ARP and ND, then the VLAN will not study

any new ARP or ND, otherwise, the study can be continued.

53.2 The Number Limitation Function of Port, MAC in VLAN and

IP Configuration Task Sequence

1. Enable the number limitation function of MAC and IP on ports

2. Enable the number limitation function of MAC and IP in VLAN

3. Configure the timeout value of querying dynamic MAC

4. Configure the violation mode of ports

5. Display and debug the relative information of number limitation of MAC and IP on ports

1． Enable the number limitation function of MAC、IP on ports
