Configuring NPIV

Configuring NPIV
The NPIV feature is enabled by default. You can set the number of virtual N_Port_IDs per port to a
value from 1 through 255 per port. The default setting is 126.
The portCfgNpivPort command is used to specify the maximum number of virtual N_port_IDs per
port on a switch. It can also be used to enable or disable NPIV. Once NPIV is enabled on the port,
you can specify the number of logins per port. If the NPIV feature has been disabled, then the NPIV
port configuration does 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 logins limit to
anything from 1 through 255, regardless of the addressing mode. Whichever of these two
(addressing mode or the value configured through portCfgNPIVPort) is lower will be the maximum
number that can be logged in.
CAUTION
The portDisable command disables the port and stops all traffic flowing to and from the port.
Perform this command during a scheduled maintenance.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the portDisable command.
3. Enter the portCfgNPIVPort
--setloginlimit command with the port number and the number of
logins per port.
4. Press Enter.
5. Enter the portEnable command to enable the port.

1. Maximum limit support takes precedence if user-configured maximum limit is greater. This applies to shared
areas on the FC4-48, FC8-48, and FC8-64 port blades.
2. The first 112 physical NPIV-capable devices connected to a logical switch using 10-bit addressing can log in 255
logical devices. The physical NPIV-capable devices after 112, 113, and higher, are limited to 63 logical devices.
3. Maximum limit of 63 for 10-bit areas connected to third-party (non-Brocade) NPIV HBAs.
