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...

Re: what is command to allow gratuitous arps on a vlan?

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:
