Description: Each octet contained in this value specifies an eight-instance group, with the first octet specifying instances 2048 through 2055, the second octet specifying instances 2056 through 2063, and so on. Within each octet, the most significant bit represents the highest numbered instance, and the least significant bit represents the lowest numbered instance. The most significant bit of the last octet is invalid. Thus, each instance to which the protected VLANs of an RRPP domain are mapped corresponds to a bit within the value of this object. A bit with a value of '1' indicates that the VLANs mapped to the instance are protected VLANs of the RRPP domain. By contraries, the VLANs mapped to the instance are not protected VLANs if the corresponding bit has a value of '0'. The value of this object must be set with h3cRrppDomainInstanceListLow at the same time when a SET operation is performed. This object is valid only when the value of h3cRrppProtectVlanConfigMode is 'instance'. If this object is invalid, it does not respond to SET operation, and it returns all '0' bits in response to GET operation.
