ReqGroupMask[n] = 1 means that the n th multicast group 232 status SHOULD be included in the answer. ReqGroupMask[n] = 0 means that this group 233 SHALL NOT be included in the answer. The number of groups to which the end-device will 234 respond depends on the available payload octets to convey the answer message. 235 236 The end-device SHALL respond to the McGroupStatusReq command with a 237 McGroupStatusAns command, which has the following payload: 238 239 Size (octets) 1 5xNbItems Field Status Optional list of [McGroupID + McAddr] Table 6: McGroupStatusAns 240 The Status field encodes the following information: 241 242 Bits 7 6:4 3:0 Status Fields RFU NbTotalGroups AnsGroupMask Table 7: McGroupStatusAns Status format 243 AnsGroupMask is a bitmask describing which groups are listed in the report.
