Use the arp filter binding command to configure ARP packet filtering based on the gateway’s IP and 

MAC addresses on the current port. After that, the port will discard ARP packets with the gateway’s IP 

address as the sender IP address but with the sender MAC address different from that of the gateway.  

Use the undo arp filter binding command to remove the configuration.  

By default, ARP packet filtering based on the gateway’s IP and MAC addresses are disabled.  

Note that:

This command should be configured on a cascaded port or upstream port of an access switch.

If you execute this command repeatedly, the last configured command takes effect. 

# Configure ARP packet filtering based on the gateway’s IP address 192.168.100.1/24 and MAC

number: Maximum number of dynamic ARP entries that can be learned by the interface. The effective 

range is 1 to 4,031. 

Use the arp max-learning-num command to configure the maximum number of dynamic ARP entries 

that can be learned by the current VLAN interface.  

Use the undo arp max-learning-num command to remove the configuration.  

By default, the maximum number of dynamic ARP entries that can be learned by a VLAN interface is 

4,031. 

If you execute this command repeatedly, the last configured command takes effect. 

# Configure the maximum number of dynamic ARP entries that can be learned by VLAN-interface 40 as
