The value of sapStatHostMacLearnOptions applies to the static hosts of this SAP. When the 'singleMac' option is set, this system ensures that there is at any time only a single MAC address per SAP, learned through ICMPv6. When the 'dataTriggered' option is set, MAC learning is also triggered by data packets, as opposed to only by subscriber control plane packets such as DHCP or ARP. A bit in this object can only be set for a SAP in a group interface, that is each row in the sapBaseInfoTable where the value of sapIesIfIndex corresponds to a row in the vRtrIfTable where the value of vRtrIfType is equal to 'serviceIesGroup' or 'serviceVprnGroup'.
