Multi-slot blades and the port offset parameter

Some blades fill more than a single slot in the chassis. As a result, they can access more ports than a single-slot blade.

The maximum number of ports available to a single slot is 8. The maximum number of ports available to a single blade is 128 (a blade can fill four slots, which is the maximum number of slots any blade can occupy at this time).

Ports beyond the eight ports of the first blade are referred to by using the port Offset parameter. Port 1 Offset 0 refers to the first built-in Ethernet port of a single or multi-slot blade. Port 1 Offset 1 refers to the third built-in Ethernet port of a blade that is double-width or more.

//IP           ,Type  ,Slot  ,Offset  ,Port ,MAC_1		             ,VLAN1	
localhost      ,eth   ,1     ,0       ,1    ,25:00:c9:00:00:00    ,1
localhost      ,eth   ,1     ,0       ,2    ,25:00:c9:00:00:01    ,2
localhost      ,eth   ,1     ,1       ,1    ,25:00:c9:00:00:00    ,1
localhost      ,eth   ,1     ,1       ,2    ,25:00:c9:00:00:01    ,2

The first two ports of each offset are reserved for the Ethernet attached card or built-in Ethernet (at offset = 0). Attempting to apply a Fibre Channel (FC) port specification to Port 1, Offset 2 causes an error. The parser prompts you that the port is reserved for Ethernet use only.
