Understanding ILOM on the Switch
Global unit identifiers (GUIDs) are unique 64-bit strings which identify nodes such as switches and channel adapters. For Oracle’s Sun Datacenter InfiniBand Switches, GUIDs are modified to identify the node’s role and location. The following table describes the GUID’s structure.
|
The five fields of the GUID are described as follows:
MAC – Bits 63 through 16 are the Machine Allocation Code (MAC) address. A standard for network components, the MAC address is typically provided by manufacturers in a 6-byte, colon delimited string. For example, 00:11:22:33:44:55.
Type – Bits 15 through 12 is the type of board on which the node resides.
Pos – Bits 11 through 8 identify the position of the board within the switch.
Device – Bits 7 through 4 identify which device on the board has that node.
Num – Bits 3 through 0 are numbers reserved for the programs which modifies the GUID. In most occurrences, the value is 0x2.
The following table provides values for Type, Pos, Device.

Note - In the previous table, the I4 switch chips are identified with alphabetical characters (A, B, C, and D). For the input of switch-specific and CLIA commands, and in other tables, the I4 switch chips are identified by numeric characters (0, 1, 2, and 3), respectively.
For example, given the following output from the ibswitches command:
Switch : 0x0021283a83b112b2 ports 36 "Sun DCS 648 shmm1500 LC slot 2 switch 1" base port 0 lid 17 lmc 0
The GUID is 0x0021283a83b112b2 or 0021283a83b1 1 2 B 2. Using the information provided in this topic:
The MAC address is 0x0021283a83b1 or 00:21:28:3A:83:B1.
The type is 0x1, or a line card.
The position is 0x2, or line card slot 2.
The device is 0xB, or I4 chip 1.
The number is 2.
