Note: Ensure that the Network MAC Address and the iSCSI MAC Address are not the same.
Configuring equal Bandwidth Weight values for all functions has different effects depending on the actual values used for
configuration. For example, when all functions are configured as "0" or "25", offloads configured on these functions exhibit
different bandwidth settings even though, logically, they would be expected to have the same effect. Consider the following
example:
Assume that four functions are configured with total six offloads, as follows.
Function 0
Ethernet
FCoE
Function 1
Ethernet
Function 2
Ethernet
Function 3
Ethernet
iSCSI
If Bandwidth Weight is configured as "0" for all four PFs, then all six offloads will share the bandwidth equally. In this
case, each offload will be assigned roughly 16.67% of the total bandwidth.
If Bandwidth Weight is configured as" 25" for all four PFs, then Ethernet & FCoE offloads on function 0 and Ethernet
& iSCSI offloads on function 3 will be assigned roughly 12.5% of the total bandwidth. Ethernet offloads on function 1
and function 2, on the other hand, will be assigned roughly 25% of the total bandwidth.
NOTE: Some vendors put restriction on minimum Bandwidth Weight that can be configured for each function. Please
refer vendor specific documentation for details.
