Cisco Round Trip Time Monitor IP Echo Admin Target Addr Type
1.3.6.1.4.1.9.9.572.1.1.1.1
An enumerated value which specifies the address type of the target. This object must be used along with the crttMonIPEchoAdminTargetAddress object as it identifies the address family of the address specified by that object. If the value of crttMonIPEchoAdminTargetAddress is a zero-length string (e.g., because an IPv4 address is specified by rttMonEchoAdminTargetAddress), this object contains the value 'unknown'.
