BM Sends the Command

Figure 34-6 on page 1015 illustrates the BM sending a command to a device's MME. The command is sent in a request GMP MAD with the following characteristics:

• ManagementClass = BM.

• Method = BMSend.

• AttributeModifier = 00000000h. Bit 0 = 0 indicates that this is a request (i.e., a command) packet.
