what is command to allow gratuitous arps on a vlan?

[jacob6000]

We have cat switches with sup720s running 12.(?)SX? revisions. What command/process is available to make them accept gratuitous arps from load balancer? Thank you...

Dear Jacob,

To enable the transmission of gratuitous Address Resolution Protocol (ARP) messages for an address in an address pool if the transmission has been disabled, use the ip gratuitous-arps command in global configuration mode. To disable the transmission, use the no form of this command.

ip gratuitous-arps [non-local]

no ip gratuitous-arps

Kindly refear to the below URL for more information about ARP configurations:
