When local proxy ARP is enabled on an IP interface,the system responds to all ARP requests for IP addresses belonging to the subnet with its ownMAC address, and thus will become the forwarding point for all traffic between hosts in thatsubnet. When local-proxy-arp is enabled, ICMP redirects on the ports associated with theservice are automatically blocked.Default no local-proxy-arpItem DescriptionSyntax [no] loopbackContext configure>service>ies>interfaceDescription This command specifies that the associated interface is a loopback interface that has noassociated physical interface. As a result, the associated IES interface cannot be bound to aSAP.Note that you can configure an IES interface as a loopback interface by issuing the loopbackcommand instead of the sap command. The loopback flag cannot be set on an interface wherea SAP is already defined and a SAP cannot be defined on a loopback interface.
