Switch GUIDs Overview

Global unit identifiers (GUIDs) are unique 64-bit strings that identify nodes such as switches and channel adapters. For the Sun Datacenter InfiniBand switches, GUIDs are modified to identify the node’s role and location. The following table describes the GUID’s structure.

63
16
15
12
11
8
7
4
3
0
MAC (48 bits)
Type
Pos
Device
Num

The five fields of the GUID are described as follows:

The following table provides values for Type, Pos, Device.

Board
Type
Position
Device
Fabric card
0xF
0x0 (Fabric card 0)–0x8 (Fabric card 8)
0xA (I4 chip 0)–0xB (I4 chip 1)
Line card
0x1
0x0 (Line card 0)–0x8 (Line card 8)
0xA (I4 chip 0)–0xD (I4 chip 3)
Gateway
0x3
0x0
0xA,0xB (I4 chips 0, 1) 0x0, 0x4 (Gbe chips)
36-Port
0xA
0x0
0xA (I4 chip 0)
72-Port
0xB
0x0
0xA (I4 chip 0)–0xF (I4 chip 5)

For example, given the following output from the ibswitches command:

Switch  : 0x0021283a8620b0e0 ports 36 "Sun DCS 72 QDR switch 1.1(FC)" base port 1 lid 24 lmc 0

The GUID is 0x0021283a8620b0e0 or 0021283a8620 B 0 E 0. Using the information provided in this topic:
