Description: Each octet contained in this value specifies an eight-VLAN group, with the first octet specifying VLANs 2048 through 2055, the second octet specifying VLANs 2056 through 2063, and so on. Within each octet, the most significant bit represents the highest numbered VLAN, and the least significant bit represents the lowest numbered VLAN. The most significant bit of the last octet is invalid. Thus, each protected VLAN of an RRPP domain corresponds to a bit within the value of this object. A bit with a value of '1' indicates that the corresponding VLAN is a protected VLAN of the RRPP domain. By contraries, the VLAN is not a protected VLAN if the corresponding bit has a value of '0'. The value of this object must be set with h3cRrppDomainProtectVlanListLow at the same time when a SET operation is performed. This object is valid only when the value of h3cRrppProtectVlanConfigMode is 'vlan'. If this object is invalid, it does not respond to SET operation, and it returns all '0' bits in response to GET operation.
