The value of tmnxOamPingCtlSubscriberName specifies the name of the subscriber to be pinged. When a non-default value for this object is specified, a Layer-2-Aware Network Address Translation (NAT) ping is requested. The subscriber name and the target IP address (i.e. tmnxOamPingCtlTgtAddress) are used together to ping the subscriber's device. A valid Layer-2-Aware NAT ping must satisfy all of the following conditions. 1. tmnxOamPingCtlSubscriberName is a valid subscriber name. 2. The test type (i.e. tmnxOamPingCtlTestMode) is 'icmpPing'. 3. The test is not an SAA test (as configured using tmnxOamSaaCtlRowStatus). 4. The target address type (as configured using tmnxOamPingCtlTgtAddrType) is 'ipv4(1)'. 5. The value of each of the following objects is default: tmnxOamIcmpPingCtlBypassRouting, tmnxOamIcmpPingCtlEgrIfIndex, tmnxOamIcmpPingCtlEgrIfName, tmnxOamIcmpPingCtlNhAddrType, tmnxOamIcmpPingCtlRapid.
