Domain ID offset modes

For instructions to convert decimal numbers to hexadecimal, refer to Appendix E, “Hexadecimal” .
When changing from IM3 with a 239 Domain ID configuration to IM2, you must first reconfigure the
domain ID offset to a value supported in IM2 or IM3 or the operation fails.
Following are the configurable domain ID offset modes:
• Domain ID default mode (McDATA Legacy domain ID mode) — In this mode, a default offset of
0x60 (96) is used. The default mode is used when you enable IM2 or IM3 without specifying a
Domain ID offset.
In IM 2: You only need to enter a decimal number in the 1-31 range when configuring a Domain
ID in default mode.
In IM 3: The Domain ID is always in the range of 97-127, or 1-31 plus the default Domain ID
Offset of 0x60 (96). For example, the Domain ID of 5 would be configured as 101 (101 - 96=
5).
