Configuring NPIV
The NPIV feature is enabled by default. You can set the number of virtual N_Port_IDs per port to a
value between 1 and 255 per port. The default setting is 126. To specify the number of virtual
N_Port_IDs per port on a switch, use the portCfgNPIVport command to enable or disable the
feature. Once the feature is enabled on the port, you can specify the number of logins per port. If
the feature has been disabled, then the NPIV port configuration will not work.

feature. Once the feature is enabled on the port, you can specify the number of logins per port. If
the feature has been disabled, then the NPIV port configuration will not work.
The addressing mode can limit the maximum number of NPIV logins to 127 or 63 depending on the
mode. The portCfgNPIVPort command can set the maximum number of NPIV login limit to anything
from 1 to 255, regardless of the addressing mode. Whichever of these two (addressing mode or
the value configured through the portCfgNPIVPort) is lower will be the maximum number that can
be logged in.

The portDisable command disables the port and stops all traffic flowing to and from the port.
