MAC address. Use the 

 command to disable the checking 

of ARP entry so the device learns the ARP entry where the MAC address is a 
multicast MAC address. 

By default, the checking of ARP entry is enabled and the device does not learn the 
ARP entry where the MAC address is a multicast MAC address. 

Configure that the device learns the ARP entry where the MAC address is 
multicast MAC address.

 Enter the IP address of the ARP mapping entry.

 Enter the MAC address of the ARP mapping entry, in the format  

H-H-H (H indicates a four digit hexadecimal number, for example 
00e0-fc01-0000). 

Enter the ID number of the local VLAN that you want to use to associate 

with the ARP mapping entry. The VLAN ID can be in the range 1 to 4094. 
Optional.

Enter the type of the port that you want to use to send frames 

to this address. Optional, but must be entered if a VLAN ID is specified.

Enter the number of the port that you want to use to send 

frames to this address. Optional, but must be entered if a VLAN ID is specified.

Use the 

 command to manually configure the static ARP mapping 

entries in the ARP mapping table. You must enter an IP address and MAC address 
with this command. You can optionally enter a VLAN ID, which also requires entry 
of an interface type and interface number. An aggregation port or port with LACP 
enabled cannot be set as the egress port of static ARP.

Use the 

 command to remove a static ARP mapping entry 

from the ARP table.
