Set FC Port QoS
This function specifies the bandwidth limit (maximum performance limit) for the FC port.
For details on the parameters for this function, refer to
"A.4.6.5 Set FC Port QoS" (page 880)
.
For the factory default settings for this function, refer to
"Appendix B Set FC Port QoS" (page 1001)
.
•
The bandwidth limit can be configured only for the ports in the port mode of "CA" or "CA/RA". For the ports
in the port mode of "RA" and "Initiator", the bandwidth limit cannot be specified.
•
If the port mode has been changed from "CA" or "CA/RA" to "RA" or "Initiator", the bandwidth limit returns
to the default value.
•
This function can be used, irrespective of whether the QoS mode has been enabled or disabled. If the QoS
mode has been disabled, the port starts the operation within the configured bandwidth limit after the
QoS mode is enabled.
•
Configure the host bandwidth limit on each host. Refer to the following sections for details:
-
"4.7.7 Set FC/FCoE Host QoS" (page 489)
